Tweaking A Compressor

[Lordnikon]

Sorry for the questions straight as a newb

I'm just looking at tweaking a Corolla Compressor ...... after abit more power, better stoppers and suspension tweaks.

Anyone got any info or links they could share

[Bodgit]

Slightly off topic but are you LordNikon from AstraSport?

On topic as the engine is the same as the Lotus 240R there is a school of thought that you could put an intercooler on and boost to 240 for a start.

I have looked at getting the pulley chnaged and remap but the tuning company were not sure about how good it would be for the cost.

Welcome and congrats on your new toy

Really, the only way I see at the moment is a flash tune and / or a pulley swap.

I have looked into intercoolers and there does not seem enough space between the supercharger and the intake to get the pipework in.

Another method is to use water / methanol injection and this is the route I may take.

I have been comunicating with TTE over issues with mine and it appears that the supercharger comes off boost at high revs. It's designed that way ;)

Anyway, I am still waiting for an explaination about why this is so. I have considered putting a feed to the supercharger electromagnetic clutch to engage it permanently but am wary about damage to the engine.

The interesting thing is that a similar Greddy supercharger produces a lot more power so I am curious as to what the difference is.

The first mod really to do to a Compressor is to remove the intake silencer snorkel and to fit a K&N type panel filter. Some change the whole filter unit but it's down to personal choice.

This will let the car breathe better for little cost.

Oh, and it makes the supercharger whine more audible which is nice B)

I dont know how true it is, however there is a chap in one of the other threads that thinks if you put the ignition on and hold the gas down until the engine mgmt light flashes, this changes the map to the default one...

Dont know if it's that simple though

There is no cost effecvtive tuning options for a compressor, a KnN tycoon air system makes lil difference but gives a nicer sound. The reason the supercharger cuts out at 6250rpm is because the secont cam enguages and there is no need for the supercharger to keep spinning. The best thing you can do is reset the ecu. i work for toyota and a technical instructor told me about this. The car is limited when it comes from the factory. if you switch the ignition on, put your foot flat to the floor on the accelerator and hold it for about 40 secs, the engine light will flash 5 times reseting all of the ECU paramaters which will in turn make a serious power difference. The instructor said up to 70bhp increase but i had mine roling road tested and im running 272bhp. Everything on the car is standard, no air system changes, all i have done is an oil and spark plug change and run it only on V Power. No other fuel will work right in a compressor, its really highly tuned which is why tuning companies dont want to work with them becasue they knnow there is nothing worht doing. The engine minus the supercharger is 190bhp, there is no need for an intercooler, the supercharger only helps with the power, the car doesnt soley rely on it!!

[bovriledcompressor]

one other thing.....

by taking off the air feed pipe as i see some have done you are actually reducing the air flow. i know the pipe is a funny shape and it goes really thin at one point but it is designed like that. By forcing the air through a smaller space the air travels much much faster and gets much better back pressure. it will sound better without the pipe but you will loose upto 20bhp by doing it!

272bhp doing nothing but reset ecu ? what a load of total rubbish ! stop BS on here

[bovriledcompressor]

why would i lie? by reseting it it takes the limiters off put in place by the factory. how do u think lotus get so much from the same system?!

[T128]

yes Lotus use same 2zzge block but the engine setup and tunning of this engine are completely different dont bother compare between the two car if you want the Lotus power of the 2zz-ge than go buy a lotus or you can drop the whole Lotus engine into your corolla either way would be easyer than to work out how Lotus tune the 2zz-ge and i can tell you they dont just unlock the ECU like you think .

ps: other than simple parts like spark plugs or oil filter there isn't much you can use on the Lotus could fit you corolla.

what i have quoted isnt just say so or what some random person on a forum told me. a fully qualified toyota technician was told by a fully accredited mechanical trainer at the salfords toyota training site. they have done what i have said to their compressor. if i am mistaken then fair enough but as a rule of thumb he would know a hell of a lot more about the whole system than probibly anyone else in the country. and also it hasnt just made a sslight difference, up to around 80mph its only marginal but now when i put my foot down in the higher gears the acceleration is 100% improved. where it used to tail off at about 120 it keeps going with gust. when i get the chance to test it further i will.

Dyno graph?

that toyota technician must be drunk when he told you all that or maybe this conversation you had with him was in your dream.

most owner on here with a compressor are running v-power with induction kit or upgrade panel filter and know how to reset their ECU how come they are not getting anywhere near 272bhp?.

you said

"its really highly tuned which is why tuning companies dont want to work with them"

i said is cos the tte charger is running near max and nothing left to tune

[european_bob]

I dont know how true it is, however there is a chap in one of the other threads that thinks if you put the ignition on and hold the gas down until the engine mgmt light flashes, this changes the map to the default one...

Dont know if it's that simple though

Techs in our workshop did this yesterday with our demo and said that there was a differance..

No need to be so aggressive T128

[StevenM]

so if this works with the compressor is there also hidden power within our standard t-sports also?

[Chris.S]

Not sure, its worth trying

I did mine and its a hell of a lot more responsive

and the differance were upto 272bhp.

and once again a toyota dealer worker have show everyone on here the awesome knowledge toyota technician or Engineer have, you can really depend on their word's.

[nrgizerbunny]

if you carry out the above procedure does it screw up the emissions? i'm thinking MOT time!

[PaulT]

I have to say I've been laughing out loud at this thread

Paul.

I keep meaning to try this with mine...Got some VPower in her at the moment...Will give it a go on the way home tonight!

[Chris.S]

i wouldnt have thought it would work and a jap built cars but the uk built ones are a poss as they use Bosch ecu's

[St3ve]

It was worth a try, nothing happend though :)

[rolley]

Here is an unusual way to test it.

STICK IT ON A DYNO

(Detect the sarcasm anyway its not unusual Jones~32 said before)

Anyway....

imo 272 is a bit on the high side, but I am not counting it out until I have firm proof of a nice dyno graph.

Least by sticking it on a dyno we can get the true results!

If its not 272 then it doesn't matter!!! (well not for me anyway i got a normal CTS )

so no bickering about the results boys and gals!!!

P.s The use of Photoshop is not allowed!!!

[Fizz]

Not sure, its worth trying

When you say responsive... Im presuming you mean just throttle response etc. You haven't said that you noticed any further power as such.

[T128]

i think this whole resetting ECU has been very overated on here.

all it does is setting ecu back to factory setting and the ecu will have to be on learning mode but after a very short while the ECU will be adape to normal condidition again then where is your so called new power ?.if people dont understand it is just like putting your foot down while the engine is stone cold it always feel more responsive then when engine are in normal condiditon,why ? because ECU always let much more air into engine when it is stone cold,if people need to find that kind of so called hidden power they be better of buying a £9.99 air flow (resisitor or chip) from eBay,atleast the resisitor will permanently let you fool the ECU without the need keep resetting but even so it just wouldn't see more HP just more responsive

but surley keep resetting the ECU manuly must do damage in the run long.

i am quite surprise so many people are falling for this.

[tsportkid]

I am sorry to say this as an ex technician but I cant believe Toyota would engineer a car that would have two parameters set in the ecu with such differences. To achieve 270 plus hp will require a significant increase in the boost pressure (somehere around the 15psi mark as opposed to 8 standard) accompanied by the additional fuel. Needless to say that at this sort of boost and fuelling you could not reliably achieve that figure without an intercooler somewhere in the induction circuit. What about the warranty implications too.
