well today i had the sx on the rollers at abbey motor sport
being told it running spot on for the current mods
apex front mount
apexi air filter
apexi turbo back exhaust
h-derv 1a chip
blitz boost controler
so on low boost it made
269hp at flywheel , 254.5hp at hubs ,219.9lbft
high boost
320.2hp at flywheel , 285.2hp at hubs 279.2lbft
im over the moon with the power, so now it just got to keep on going up now
That's very very optimistic on the power. The turbo and injectors are maxed out at 290bhp roughly. You have an extra 30 over that. Id say there rollers are a bit out.
320hp ... on a 1a setup
Your having a laf
Another one of these Rolling roads which give imaginary numbers lol
It does seem like somethings not quite right there.
Trans losses at low boost were 14.5bhp and at high boost 35bhp!!
I would question the results with Abbey and see if they can shed some light on the figures.
Ps, guys, i think abbeys dyno is a HUB dyno pack, not rollers. (i could be proved wrong though)
Can always count on people round here to shoot you down when you feel happy about your car
Although the figures sound higher than they ought to be, at least if its running right thats good
Pop over to http://www.tracknroad.com/ for a dyno run at some point, they'll give you an absolutely spot on result and advise on anything thats not quite right.
Good result, doesn't matter that it's high - looks good on paper and will probably help come sale time
hooky, trans losses are a % remember, but yes it does jump a little too much (or the lower figure is just too low)
I was expecting replys like this tbh,not I think the rollers are out!,Its winter so colder denser air and its made 285.2 ath/wheels that's a good realistic figure and believable imo,and to be told its running spot on even better! just bit surprised at the commentsOriginally Posted by Ghazoobe

No one is shooting him down , Were just puzzled why some places tell you what you want to hear .
It just sounds far too good for the modifications carried out.
He has paid good money for a service and it may not be the actual truth therfore they may aswell just wrote a figure on a piece of paper.
But at the end of the day if he is happy that is the main thing.
I just here of so many places coming out with these nice figures and i think its not fare on the customer
Which makes no sense at all because the drivetrain hasn't changed between runs.
My car lost about 40bhp when it was standard and had still only lost about 40 when it was 375. A percentage only works on a completely standard car.
320 on standard 370cc's?????
Pretty much what i was gonna say, the losses should be the same not different.
Transmitted losses are not a percentageGood result, doesn't matter that it's high - looks good on paper and will probably help come sale time
hooky, trans losses are a % remember, but yes it does jump a little too much (or the lower figure is just too low)
It's a bolt if hub dynopack which are rated for near on 2000bhp for the drag cars.
Also also I did not pay for the service so why would they lie?? I got the paper work also, I had them set up the boost controler propley also.
I was expecting ppl to shoot me down on my results like they do on every forum.
And realised I did a typo it was 259 not 269
People dont believe its accurate for a good reason (and we have been over this many a time)
320 on a stg1a is exceptionally high for that tune,
Its a fair bit over the stock afm capabilities which is roughly out of ideas at 300hp
Its a fair bit over the stock t28s capabilities, even if it was new - its out of puff at about 300/305
Its way outside the stock 370cc squirters as well ....
So unless you aint got those on the car its got to be a bit optimistic, 300 would be a good result on that tune.
Heck a 2a map and tune would be doing well to reach a legit 310..
Ok kill joy, know not to post to much on here in future.
Just can't see why they would lie? I don't have any of my work done there so it's not like they make money from me.
But oh well
I had the same problem,I got my car dynod and was very happy with the results and then was told by people that it wouldn't be nearly as high as I said.a bit of a let down lol.
The good thing is it shows even if it is out slightly you have a healthy engine
So a few people question your results and your not going to post much in the future! This site is full of enthusiasts that know the cars and setups very well and the correct power levels they should achieve. As long as your happy with your car don't worry so much.

The thing to bear in mind is that hub dyno's and rolling roads measure the power at the wheels, the flywheel figure is guestimated using the operators knowledge.
Personally i only ever quote the figure thats been measured because everything else is debatable.
Also abbey may very well be telling you the truth as they see it, the dyno may not have been configured or sensors are beginning to fail giving false readings but unless you calibrate it regularly then you wouldnt know its reading wrong
Absolute rubbish! A 1.1 fiesta has 10hp loss, a 200hp fiesta has 30hp loss... go figure.
In the threads example the losses are inaccurate as the increase in power isnt proportional to the difference of the loss, but generally speaking, of course it's a %, think about it for a moment.
