RedeX

[JB]

Anyone know anything about Redex Fuel Injection treatment?

Is it worth it/does it work?

Cheers

I recently used some (not redex but similar stuff) and didn't notice any difference, however, my girlfriends dad used some in his Daewoo and that did (smoother running/more power).

Try it and see, can't do any harm..

Cheers Dave.

It's the harm bit that concerns me 'cos Slick 50 is supposed to do more harm than good.

I've used it in mine and no difference whatsoever. Nor in my sisters vauxhall. Has anyone used that 10k boost thing? idoes that work at all?

Think of injector cleaner as a preventative thing. It will help stop the injectors getting bunged up.
If they already bad it will not miraculously clean them regardless of what it says on the packet.
I put a strong dose in a 1/4 full tank every 3 months or so but have never felt any change.

All 10k boost is a carb cleaner. Nothing more.

Ive used the RedeX of a few cars, you can tell the difference more of a carb than with infection. A good one is the plug removal one, loadsa white smoke for about 3 miles - great fun.

We also used it - James Bond Stylee on my mates mini!!! We emptied his screen wash bottle, and filled it 50/50 with redex and petrol, moved the screen jets to point down in to the carb, and went out for a drive. Anyway, about 20 mins later we have some Citroen AX right up our behind, so a quick squirt of the screen wash button, and the redex mixture goes in to the carb. The headlights on the AX instantly went yellow through the smoke, then dark brown, and then totally disappeared. When the smoke cleared it turned out, he had to stop cos the smoke was that thick.

We did this all night, and had a great laugh, not sure it did his mini much good though http://300zx.co.uk/200sx/ubb/biggrin.gif

I've used 10k boost and its a right bitch to spray it correctley if you follow the instructions, all I seemed to do was fill the housing with the stuff,the only way to succesfully get it in was to remove the pipe after the AFM, and then the engine dies so you still cant win. I must have wasted over half of it. It did work on my misses NA engine though because all you have to do is take the air box lid off and spray straight into the intake.

I'm sorry Dave and Nathan I hate to differ, this stuff is great, I used two cans, one in front of the airflow meter to go through the turbo and the other through just before the plenum and what a difference it made !!! To do it through the airflow meter I used a tissue roll put into the intake hole in the airflow meter and squirted down that to miss the hot wire !!! job done. (and I've never seen carb cleaner that turns white and frothy !!!)

I FOUND THAT 10K BOOST STUFF WORKS BEST IF YOU SPRAY FOR 10 SECONDS THEN LEAVE FOR 5 SECONDS UNTIL THE CAN IS EMPTY, NOT HALF THE CAN IN ONE SHOT LIKE IT SAYS ON THE TIN, OR IT JUST DIES, AND STRUGGLES LIKE MAD TO GET GOING AGAIN.

NOW TAKE IT FOR A SPIN, 1st LOADS OF WHITE SMOKE, THEN NOT MUCH CHANGE REALLY, UNTIL YOUVE DONE ABOUT 20 MILES AND GOT IT NICE AND WARM.

THEN THE DIFFERENCE IS GREAT, I FOUND IT JUST GOT QUICKER AND QUICKER. SUPPOSE IT COULD BE DIFFERENT FROM CAR TO CAR THOUGH, DEPENDANT ON CONDITION ETC.

I got some stuff from Halfords called Nitro, in a bright orange bottle. It claims to up the octane rating and clean the injectors. It is bloody fantastic! Smoother tick over and more power all in a handy bottle....BRILLIANT

I know the stuff, I run it regularly, it's made by car plan, anyone on the old board will know I practicaly drink the stuff. I swear by it, 3 bottles the last time at Santa Pod and I blame it for me lighting up the tyres. great I love it!!! octane boosting through the roof and flames off the wheels! cant go wrong, even if paul laughs at me, he cannot deny the truth or steve and matt for that matter. I may have the slowest time but who had the highest speed guys? heh heh cant wait until the 17th redemtion time http://300zx.co.uk/200sx/ubb/biggrin.gif http://300zx.co.uk/200sx/ubb/biggrin.gif

Can you use Nitro with a catalytic convertor? Anyone tried any other octane boosters - the only ones I've found locally have been designed for cars without cats. I know Millers make one thats cat safe.

These conflicting personal anecdotes are all well and good, but has anyone got any hard data about the impact octane boosters have on a particular engine? I'm thinking of before and after dino readouts etc. As far as I understood petrol formulation, the octane rating just dictated the capacity of the fuel to resist (pre)detonation, thus allowing the design of higher compression ratio engines with increasing octane. There is no association between octane and calorific value (ie power per burn), so unless your engine is running poorly because of an excessive compression ratio, adding more octane to the fuel won't improve performance.

Having said all this, if anyone is interested in sourcing high octane fuel to test this for yourself (for drag runs, trackdays etc), the place to go is your local airfield where you can fill up with AVgas. I run a 2 stroke racebike, compression ratio of about 15:1, it will only work on AVgas.

S14, logbook says emerald, actually dirt coloured.

[Tom_S14]

Yep,
You're completely right, there's no point at all using octane booster unless you've got detonation problems. It might well make the engine run slightly differently, petrol is a mixture of hundred of hydrocarbons which are changed seasonally, more volatile ones in the winter for easier starting etc., so changing the composition of what's in the tank will have some effect.

I know 200's aren't all that "economical http://300zx.co.uk/200sx/ubb/smile.gif" but pouring this octane booster down the hole of no return must cost you guys a fortune ?
Anyhow, toluene does seem to be a popular ingredient for octane boost products, and you know what carb cleaner is... a lot cheaper for one thing.
Redex tends to make a lot of white smoke because (guess what) most of it is oil !?!?!
All you're doing half the time is burning the redex itself ! Good bit of marketing really.

Goeff, how much do they charge you for av gas ?

Tom

[Papa Lazarou]

Absolutely there is no increased 'calorific value' from using higher octane rating fuel. However it does allow you to run higher boost safely, as increasing the boost is effectively increasing the compression ratio of the engine.

The main reason I was wondering was as the car is a Jap import (which really needs to run on Super) could I get away with 95 RON with an octane booster if necessary (not everywhere keeps Super). I know it will run on regular u/l but not brilliantly (the ECU retards the ignition and lowers the boost level etc.)

PS I just thought about pulling up to a hangar at Cardiff Airport asking them to fill 'er up http://300zx.co.uk/200sx/ubb/wink.gif LOL

Nitrox does claim an increase in 10% more bhp, as I've said before (old board) I dont realy beleive this so much with a tuned engine. most cars are built to within tolorences which will allow them to be run in most countries taking into account humidity, heat, cold and fuel quality. there is only so much a computer can compensate for. the more you tune an engine the more tolorence you take off. It may well give an extra 10% bhp increase in your fiestas etc but you probably wouldnt notice the extra 7bhp on top of 70. adding nitrox which is mainley methonel with NPX2 additive does increase your fuel quality, running it with super UL + Nitrox I find the engine alot more livlier with better pickup smoother power delivery and to cap it off I reckon I get about 50 more miles to the tank. there is a but though, you have to run 1 bottle per 15 litres, I know its not the cheapest way but for the difference it makes for an every now and then run then sod it it's worth it. Im not claiming I get maxpoweresk type bhp claims but I will say that the car feels more responsive and 0-60's are faster, that I have proved by around .4 of a second. which is a hell of alot. being as though its take over £2000 to knock just over a second off.

Think this covers most of the above, note Nitrox is over 50% methanol so now I wouldnt recomand running it all the time haveing read this.

INCREASING OCTANE DOES NOT INCREASE POWER
Higher compression and improved engine breathing will increase power. These modifications may lead to detonation or combustion knock which is then eliminated by using fuel with a higher octane.

ALL PETROLEUM BASED FUELS PRODUCE SIMILAR POWER

Petrol refining produces a blend of hundreds of different hydrocarbons that have the required properties to meet the needs of spark ignition engines. It is well recognised that varying the blends has little effect on the power produced in an engine.

BP 100 IS A HIGH OCTANE FUEL THAT HAS GOOD VAPOURISING CHARACTERISTICS

High octane is required to avoid detonation when compression pressures are increased by either high compression ratio or better breathing. The narrow boiling range of BP 100 will ensure good mixture preparation because the heavier hydrocarbons of normal petrol are avoided. Also the lack of very low boiling temperature hydrocarbons will prevent hot fuel handling problems such as vapour lock.

BP METHANOL HAS SPECIAL PROPERTIES THAT INCREASE POWER

Methanol is the only readily available fuel that produces any significant increase in power over petrol. Methanol allows extemely high compression ratios to be used to produce more power. In addition, with methanol the engine can cram more energy into the cylinder for three reasons:

i. The large amount of fuel being consumed.

ii. The cooling effect when methanol evaporates raises the density of the mixture ie. even greater energy content of the mixture.

iii. Methanol contains oxygen within its chemical structure, which acts like a chemical supercharger.
Methanol requires about 3 times the flow rate of petrol so the fuel supply system usually requires significant modification.
Avoid lean mixtures because methanol has a low resistance to pre-ignition; the high exhaust valve temperatures caused by slow burning lean mixtures may induce pre-ignition and hence piston damage.

TOLUENE IS A COMMON OCTANE BOOSTING COMPONENT

Toluene (methyl benzene) gives about 1 octane number boost for each 5% added and the mixture may need to be slightly richer also. The higher octane allows the use of a higher compression ratio for more power. Toluene has a high carbon content that may lead to sooty spark plugs so don't assume that this indicates an overly-rich mixture. Toluene is also a good solvent, and high concentrations may affect rubber and plastic components in the fuel system.

Methanol the way to go then??? It works for me http://300zx.co.uk/200sx/ubb/biggrin.gif maybe I should be more carfull with the wording of my anecdotes, It also tastes rather nice http://300zx.co.uk/200sx/ubb/wink.gif also on the redex front when I used to race offroad in landrovers ( http://300zx.co.uk/200sx/ubb/redface.gif) another competiter said of it " why the bloody hell would I want to put diesel in me tank" which kinda ties up with what Tom says on the oil thing, I never did understand what he was on about until know. I have some nice pics of my landie on it's side after the sun hide the 6 foot drop to the left. anyway onto the point, I can vouch for the nitrox stuff but none of the others, as I've since been in touch with a drag racing nutter who said yeah they clean but thats it, it's only the methonal in nitrox that makes the difference and NXP2 is nothing more than a gimmik, aparantley its been around for ages as a good detergant and nothing more. so sorry I was kind off wrong, he also said running methonal all the time was a bad thing which I had kinda worked out, but you can run it as one off's mixed with decent fuel. also did you know these crazy gits run a 3 stage fueling system 1 petrol 2 methonal 3 some kind of nitro. theyre actualy running an engine on high explosives with the 1st two stages just to get the engine running, now theres an upgrade if I ever saugh one, fill her up with nitro glycerane mate.
