View Full Version : Woo! 483bhp from my S13
Managed 483bhp (at the wheels apparently!!) today at the rolling road at Janspeed, Salisbury. Very pleased indeed!!
And I'm still using the standard CA ECU :)

The gap in the graph is where the rev pickup on the coil pack misread.
Looks Great :D
Lovely Torque curve.
Get that new frontpipe and get to Thor, that should give you a 500@hubs figure :D
Awesome :notworthy
Im up for a meet at Thor in the near future if you fancy it. :nod:

What revlimit are you using? The power curve is still going up when they stopped...
Still :notworthy though :)
Im up for a meet at Thor in the near future if you fancy it. :nod:
Yup - I'm up for that :)
Managed to break my AEM CDI ignition system and the inlet manifold has cracked again (on the way back from the rollers) :( But I don't care I'm on holiday in a bit :D

Yeah, I know - scared of bending the crank. That was taken to 7200rpm
Wow that's impressive...:thumbs:
unfortunately makes my result look even more weedy:cry: :wack:
This is why you had to rush off home :D
Was good to see that earlier :nod:
If i leave mine with you for an afternoon can u make it do that:D Very impressive:thumbs:
Bloody hell Jez :clap: :clap:

We will have the new throttle body on Monday so our S13 should be done for when you get back. We can sort it for soon after if you fancy it :)
Just had a thought, you now own the most powerful proven S13 that I know after Tones bad luck :( :)

Yeah, thats right "only" 230bhp at 4500rpm :)
What did they say when they saw the figures? Were they suprised?

Yes :)
I think its the most powerful car they've had there so far (someone will correct me if I'm wrong)
cool, yeah didn't mean that bad or anything god knows that thing is a spaceship ;)
LOL - didn't mean to sound nasty in my last post :)
what do you think the fly figure is jez over 500 now :)
Yeah, probably. And this was just on Tesco fuel.

Very impressive :)
How about an 8k rev limit and a tank of race fuel? ;) :D
Very well done mate, how far, in real terms do you think u'd like to take her too?
Well done mate, you must be well chuffed.
Are you still using the GT30 turbo?

and now I'm off round to your house to steal a 500bhp S13 :D
Now all you need to do is get it to idle ;)
alanjuggler
04-12-2005, 18:38
not gonna happen :D
same with my car, 950cc injectors dont really have a lovely stable idle :)
good result jez, i have faith in you to finish mapping mine and hopefully might hit about 100bhp below that at the fly :)
got your initial remap too today, have a good holiday :)
Nice one Jez,
just one question, how does 500 odd bhp affect laptimes ?
do you have any before and after mods times from your sprints ?
Cheers
Steve
Yes :)
I think its the most powerful car they've had there so far (someone will correct me if I'm wrong)
Aye tis true, and they have tested porsche turbos and the likes. In the morning I took second spot on their rolling road chart 5bhp below a 360rwhp supra, that was until Jezz, Papa and pointblank came along lol.
They did not believe me when i said my engine only had a head gasket and cams, but they liked the glowing manifold and lack of reverse gear.
Now all you need to do is get it to idle ;)
Yeah - does need a bit of work - its not normally that bad, think it might have been the beginnings of the inlet manifold cracking again - its now got a huge crank in it... :indiff:
Just wondering Jez, at what point does the stock ecu become restrictive?

Considering the power it's running, I think a lumpy idle is hardly a problem. They do sound :smitten: Anyway, aren't you supposed to be on holiday? :whip:
Just wondering Jez, at what point does the stock ecu become restrictive?
Not really sure - at the moment its running a Z32 AFM and 950cc injectors. The main limit is the Z32 AFM - only :wack: good for ~500-550bhp. I'd have to mess about with a dual AFM setup if I wanted to higher - I could get it to work I think.
Anyway, aren't you supposed to be on holiday? :whip:

Isnt there a Q45 or something AFM thats bigger?
And did I imagine you saying at somepoint that you might try and run the CA off a SR ECU as it offers twice the size fuelling points to play with ? 16*16 instead of 8*8 ?

...d run the CA off a SR ECU as it offers twice the size fuelling points to play with ? 16*16 instead of 8*8 ?
As far as I know the CA ECU has the same resolution as the SR. I think the SR only has the advantage of offering the consult port which is very nice if you want to monitor or log sensor data.
btw, nice numbers Jez :thumbs:

Q45 MAFs are larger but max out with less airflow. They're good for about 450bhp IIRC.
Time to go standalone with speed/density and wideband feedback :D

Are you using a GT30R to hit that numbers? I´m stil considering what I should buy now to bring my project to an end...

Fantastic :notworthy: nice one.
If you guys go to Thor you better let me know as it's only just up the road from my pad, and i'd love to sit in on the rr session! :Plug: :D
Cheers guys :)
MarkH, I'll drop you an email - it'll be interesting to hear what you do.
I expect the Thor RR day will be well publicised - whos going to win? Bren or me? Place your bets ;)
I think it will be pretty close. We now have the larger 3076, nitrous and the larger throttle body along with some sexy additions to the management hardware and revisions to the mapping. Looky at the size of my new throttle body! :eek:
http://www.sxoc.com/vbb/attachment.php?attachmentid=25401&stc=1&d=1133951291
The sequential box isnt being fitted though, we would have to send it back to Quaife to have the S13 bell housing shimmed up and then back again to get it reshimmed for the S14 :(
Crikey, you'll be hoovering up small children and stray dogs as you drive past with the size of that intake :D
Hopefully we wont have to run such high boost with the larger apeture :)
RR day will be well publicised - whos going to win? Bren or me? Place your bets ;)
Tough one, if Bren hadnt ditched the inlet manifold I would have said Bren, but that seems to have enabled quite a jump for you. If you can keep it from falling apart and run with it then its going to be close :nod:
And you'll both make Buffy's monster machine look under powered, despite being a daft car. Will be nice if at least one of the SR big BHP turns up too.
Enigma !!! Where are you and your mid-12 1/4 car ?? :smash:
I think it will be pretty close. We now have the larger 3076, nitrous and the larger throttle body along with some sexy additions to the management hardware and revisions to the mapping
Nitrous is cheating :indiff:
I think it'll be close too (without the nitrous)
Sounds like youre running scared ;)
If nitrous is cheating then so is using WI. Its one means to increase power or performance as is WI. Turn your WI off and Ill turn off the nitrous, deal?
I want to see if Jez aggress that if nitrous is cheating then WI is cheating and if he will wstich WI off if I turn nitrous off :nod:
Ahhh not quite the same though bren, you can't add WI to a vauxhall nova and make an extra 100bhp. Whereas with enough nitrous you can :)
Nice result btw jez. just shows what standard management is capable of :) it may have made more if the manifold was on it's way out.
Its injecting a liquid as a means to run more power. :nod:
In that respect you could say the same about petrol.
It is just the fact that a 1.0 litre nova can be made to double it's output without too much trouble. whereas with WI a lot of 'tuning' would be needed to the engine first to equal the same increase in power :thumbs:
Ok then, Ill forget the nitrous but will run race fuel :)
Thats similar to WI injection in that just running race fuel wont be of any power benefit, it simply allows you to tune the car to a more advanced state, just like WI does.
But no, race fuel is 'cheating'. Therefore WI is 'cheating'.
So lets none of us cheat, Ill turn the nitrous off, no one runs race fuel and all WI systems are turned off ;)
Stop fighting guys, power is as power does.
I think whatever you run on the track, in normal use, is allowed.
WI, Nitrous. Dont think anybody runs race fuel on the track @ ~5mpg !!!
don't become dyno slags sort it on the track :nod:
/Steve
Like your sig, looks cool :nod:
I've got WI (not fitted it yet), but intend to use it purely as a cautionary matter against detting...
But from what you're saying Bren what power gains can I expect it to give me?
Sure Bren and Jez will be at a few tracks again next year, Bren has bigger brakes so that could be to his benefit.
WI - allows for timing advance, lower EGT's, and if on big boost allows less overfuelling if you had to overfuel for extra cooling / to lower EGT's
So in essence it doesn't do anything unless you adjust timing or mapping for it, much in the same way as using a higher octane fuel?
I probably wont have bigger brakes for long :no:
Youll lose power if you just fit WI, you need to make use of the water by advancing the ignition timing and/or raising boost to get the gains. You can also run a leaner mixture.
How lean a ratio are we talking here? What would a typical gain be? Bit of a non specific question seeing that one car is completely different to another...

Aye race fuel and WI have the same effect of allowing more advance etc. But any rude boy can stick a 50bhp shot of nitrous on their shitbox and make it go quicker. But it's a different kettle of fish to put race fuel in the car and tune it to take full advantage of it :) That's the only thing in tuning that I think is 'cheating' for that reason :)
He started it :p
No he started it...... lol :wack:
Everyone loves a bit of healthy competition :D

Jez posted some details, have a search for his WI thread.
From memory he was about 10.5:1 at high revs, with 950oC EGT's before WI.
Then almost at 12.0:1 at high revs with the same EGT after, and more advanced timing.
Pretty sure full details are in Jez's thread, mine from memory may be wrong :wack:
OK...Coz at the moment i'm around 12.5:1 at 17psi and therefore have dropped down to 15psi.
I might just wack it in and see what happens.
The car will be running standalone soon, so proper mapping will happen early next year, and i'll prob get them to run a different map for use with the WI...
Anyway end of the slight thread hijack...Well done Jez I'm jealous...

We arent talking shitbox cars here though, we are talking cars already putting out nearly 3 times their original output. Running nitrous safely on a car in such a state of tune isnt the same as "any rude boy can stick a 50bhp shot of nitrous on their shitbox and make it go quicker" :no:

and make them think they do a 9 second quarter :D just like the fast and the shitty :D
Engmia has a toggle switch via the motec that (I think) dials in a extra 12 degrees of ignition when the car is running on race fuel. Reckons it makes around 50bhp difference.
Oh and stonking results Jez :thumbs:
Si :)
To put this in perspective....
I was on the same Dyno day and got 237 at the wheels, might be able to improve upon that a little with a custom map but Jez managed to get twice the power I'm running, I'm using a T28 Hybrid :)
Then again I had loads more torque at 4000rpm :D
You will beat me if you run nitrous - you can just fit bigger jets and get more power. WI doesn't add more power (water doesn't burn), just helps prevent det.
I guess we could both run race fuel, if you're paying. ;)
Race fuel has a higher calorific value and is more det resistant. Just bloody expensive...
Ill beat you anyway :p
The nitrous is being used for anti lag only, it switches off early on, just wanted to scare you ;)
We ran similar power to Mike Rainbirds Cossy and that ran 510bhp on Harvey Gibbs dyno. We had a front pipe to turbo elbow leak and it was 23+ degrees ambient temps :nod:
We have since fitted a larger turbo, larger throttle body, taken out the plenum, fitted a higher flowing fuel pump, added some sophistication to the management and its all getting remapped :nod:
Thats the royal we of course, we being Gary :)
LOL :)
So you're happy on pump fuel and no NOS then?
Aye, like I say I am not running nitrous at the top end. Its too unpredictable to map as the bottle pressure changes with ambient temps etc so its fiddly to guess the map. Not worth the grief :no: We are just using it to get the car up and pulling and its doing a very fine job by all accounts :)
I did order some race fuel months and months ago but it never turned up so we gave up on it. Its also a faff to drain and refill the tank, Im too lazy for all that messing about ;)
Really good work Jez:thumbs:
Cool - so we're set :)
I'll let you know when I'm ready and we can sort something out :)
looking forward to seeing this one :)

though i dont know how you drive these cars.. mine is a bloody nutter even at relatively low boost. i think i need to learn more precise throttle control :wack:

09-12-2005, 09:32
LOL :)

Some dyno operators/owners won't allow nitrous because of the too temperamental points that Bren makes
This should be good :D You two could sell tickets :D
Gary has all the parts he needs and they are just finalising the car now, we should be good for first thing next year :) Or maybe even just before Christmas :nod:
Can you make your Thor date early Jan please :D
I may be ready before Christmas - depends on wether my CDI is ok or not. If not I'll have to get another from the states which could take a while.
Ah, I thought you were ready when you said you were all set :)
Theres a cheap trackday at Donno on the 29th of Dec :)
Would love to see that... where's thor?
Got to say... Thats ~560 flyHP on the old style Apex intercooler :D
I may be ready before Christmas - depends on wether my CDI is ok or not. If not I'll have to get another from the states which could take a while.
wont you wait for lil o me :(
Depends when you're going to be ready I guess. We could always do another later on :)
Our S13s life is now limited so if we are going to attend then itll have to be sooner rather than later :nod: :)
you're gonna lose the S13 Bren?
Aye, shes going to have to go. The S14a is going to (like it hasnt already) suck up a HUGE amount of cash and I have plans for another car so the S13 has to go. Its been pushed as far as we can take it on standard posiiton internal wastegate turbo so in terms of business usage shes done for :(
I really thought you'd keep her for the track :(
Cant afford to run loads of cars and, as I say. something new has come along so something has to give :(
Its still a 200 though :)
alanjuggler
11-12-2005, 23:16
a thor day might be good, if i can get my oar in and run my car too. jez is finishing the mapping in jan so i should be ready for janish. :)
bren:
it's a shame about the s13, it was my favourite of your test cars :)
but im already starting to think in vulture mode! - you've done evil things to me, with all your old parts :wack:
Pah ... i was thinking in vulture mode long before this ;) (Not that i want to see that car broken :()
but im already starting to think in vulture mode!
:rolleyes: I already PM'd Bren my wish list :wack:
Will the s13 be offered for sale as a complete car prior to breaking, Bren? :)
Nah, no one will pay what Id want for it :no: The only way to get the money back out of it is to break it :(
The cars worth an easy £15k in bits, no ones going to pay that :no:
Its still a 200 though :)
Oh christ, you're branching out into Rover modifying arnt you :(
:wack:
So what are the "rules" then?
Can I run race fuel? :wack: I did at Bruntingthorpe but didn't have my laptop with me to adjust the timing, I just used it as det prevention there (didn't see much point as I was wheelspinning most of the way through 3rd due to the weather). Managed to go through 20 ltrs. in ~27 miles :eek: :D
Rules are:
1. Pump fuel, cos its chuffing expensive and a pain to swap from pump to race fuel.
2. No NOS, cos its cheating ;)
Coming along? :)
what about WI????
sound good to me :nod:
what about WI????
Thats ok :)
But pedantic Bren said it was cheating :wack:
So Jez can cheat but we can't? :cry:
I dont think any of its cheating to be honest, whatever floats your boat. However if nitrous is cheating then so is race fuel and wi because they give an advantage in that they allow the timing to be advanced/boost to be raised/mixture to be leaned off.
We'll let Jez use his Wi then. I know how to hamper him. ;)
I'll have his plenum tomorrow :D

Gary@APT
13-12-2005, 21:19
bren is hampered big time at the minute.....
it dont run yet!!!
I know, Im just saying that I personally dont think any of it is out of order, whatever you do to increase power is ok by me :)
I'll still be ~100bhp behind you two idiots even running race fuel :cry: :wack:
Brens right really, any of the methods of getting more power are viable in a dyno queen shootout.
I need WI for my car to produce decent power (or race fuel without WI), which is why I'm a bit biased ;) But having said that, in the class I sprint in WI is allowed, NOS and race fuel aren't.
The way i see it, race fuel allows more power due to higher octane, and NOS due to extra oxygen added to the intake charge.
WI is a method of reducing charge temps and is a differnt league to the others due to this.
How does race fuel 'allow more power' due to its octance rating?
How does race fuel 'allow more power' due to its octance rating?
Race fuel generally has a higher calorific value and contains more free oxygen than pump fuel - this gives you more power. Its also got a higher RON/MON (as you know) which helps prevent det allow more ign advance to be run, again more power :)
Ah, its a det inhibitor which allows the timing to be advanced/boost increased to achieve more power?
Sounds suspiciously familier to wi ;)
And would that there water contain methanol by any chance?
The way i see it, race fuel allows more power due to higher octane, and NOS due to extra oxygen added to the intake charge.
WI is a method of reducing charge temps and is a differnt league to the others due to this.
Adding water increases the charge's resistance to detonation, its in the same league as higher octane (race) fuel.
NOS adds more oxygen which requires more fuel to be added to maintain the same AFR, more fuel burnt = more power. Its more effective at adding power this way so it is in a different league.
They all allow more power to be obtained.
The only way to test the engines is to run them on the same octane fuel in the same air (temperature, pressure and humidity must be the same). Or on a rolling road that has air compensation. Water, NOS, differing fuel would have to be taken out of the equation.
The way to test who's set up is the most powerful is to run them with what ever setup they arrive with on the day. If it were an outright power battle then they'd all be running Methanol which has some obscene oxygen content.
WI allows a little more advance to be run, its not up to 118 octane though and doesn't increase the energy of the mix.
I do use some methanol in my water as an antifreeze and extra coolant - I can run plain water if you like though :)
I dont care, Im just not going to agree that WI is significantly different to the other means of increasing power :)
Its just a bit of fun, Im not that bothered if we come first last or dont run at all. Its a bit of a giggle, thats all :nod:
If I was so anal about winning then Id have sent race fuel and water injection to Gary and would then have got him to map nitrous to the redline.
EDITED
Im doing a 180 degree turnaround and we are going to have a play with WI on our S13. Ive spent all this time arguing how good it is and have just realised that its actually probably pretty good :wack: So Im going to find out :)

LOL - you should be in politics :)
*** points and laughs at Bren ***
Go on, get the Nitrous mapped past 5K while your at it ;)
We have sold our last WI kit, I didnt know :cry: Ill have to get one ordered.
IMO... WI just reduces inlet charge and reduces chance of det, race fuel does this too but also has the higher calorific value so is cheating to some extent, NOS adds oxygen in massive volumes (also reducing charge temp) so I would class it as not playing on a level playing field... it's all personal opinion, whoever has the most power and torque etc wins, TBH doesn't matter how you do it.
Methanol would actually reduce RON and MON IIRC, it barely makes a difference, TBH I wouldn't use it unless it's v cold as it is known to cause corrosion in the engine :(
Jez just likes winding Bren up, and it's funny to watch :D
Be intersting to see WI, NOS and everything on your engine Bren, that could have some mentally massive torque mountain range :D
On an side note, what sort of value would WI be for me running Stage 3 on an APT Stage 1 engine? Just dipping a toe in the water before I finalise my next plans ;)
More torque lower down?
How much would a comprehensive mapping session be on WI and how much is WI set-up?
Our cars fit now but I dont want to go all the way down to Thor until we have tried out the new bits and hopefully got our power to climb all the way to 7500 rather than flatlining at 6k.
The new bits will be here mid March so we arent a million miles away :)
Sounds good to me :)
I just got my car running correctly, and the manifold hasn't split again - done a trackday and about 500 miles so fingers crossed it'll stay together now.
Shall we say end of march then? Will that give you enough time to get the parts fitted and working?

Chris - only just saw this :rolleyes:
WI won't increase power as such - i.e. if theres limited boost and ignition timing is set correctly without having to compromise for det then you won't gain anything. It's good for situations where you are having to overly retard the ignition to stop det, at the expensive of power. It will also help to reduce in cylinder temps and EGTs.
The main reason I use it is because my comp ratio is a little high for the boost I want to run meaning I'd have to retard the ign (which increases EGTs) a lot to stop det (or take the engine apart and reduce the CR).
I use an Aquamist WI kit with their MF2 controller - works very well. I think Bren sells the kits, not sure how much though. I can map it all up if required :)
