Compressor Twin Exhaust

[Chris.S]

I've noticed on my compressor that only one side of the exhaust gets hot and has more steam coming out of it when cold. Dows anyone elses do this ?

Does anyone know if the is a valve in the exhaust that opens at a certain power range.

This i think is normal!!!

The reason is gasses out of an exhaust will escpae out of the fastest route, i.e the backpipe directly connected to the backbox!!! the secondary exhaust pipe is primarily used when you get a backup of fumes in the backbox that can not be shifted directly through the directly connected exhaust!!! Thus why it won't get as hot, because not as much fumes will go through it!!

Hope that clears that up for ya!!!

Its the left hand pipe that gets hot while the main box is cool

does that sound right

Its the left hand pipe that gets hot while the main box is cool

does that sound right

if you look underneath the exhaust gasses go straight to the left side and then through the box so fumes would be hotter cos not passed through box to cool down first:thumbsup:

i thought the twin pipe was only cosmetic on the compressor and that only 1 pipe was actually connected. Would i be right ??

No, both pipes are connected.

The passenger side actually comes out of the front of the silencer.It does pass gasses through the box.

I always think it looks lop-sided so am considering a new system to make it look more balanced from the rear!

[Chris.S]

If i change my system id have to have the rounded ovals again as i think they good on the car

[chrisio]

Very true, same here!

I followed a compressor across the Forth Road Bridge the other day, actually the first one I have seen on the road, and is it just me or doesn't the twin exhaust setup look completely naff?

I mean, you can clearly see the large silencer and exhaust, same as the TS, and the bit of pipe that looks like it has been welded on as an afterthought to the second pipe. Not very aesthetic!

itotally agree it looks proper naff in real life its such a shame that rear bumper looks class and with the right double exhaust it'd finish it off to a T but it just looks cheap. And if u didn't know u'd think the owner had found some spare scaffolding poles and been bored one afternoon.

I've been thinking about changing to a compressor but things keep cropping up and i personally think the compressor on the vvtl-i is an after thought.........no intercooler....some dodgy cluth thingy... i'm sorry i'm sorry guys with compressors' but i just think they are not the hit they were mean't to be?

Maybe i'm completely wrong and i'm sure some compressor owner will put me in my place...........

Just my thoughts

[Chris.S]

ive painted my exhaust black because i didnt like the way you can see a large silver silencer,

Same here T-Sport_Jay. My TS was in for service the other day and I had a good look round a 6 month old Compressor that was on the forecourt. 7k miles on the clock and priced at £14,999. The wife even said I could buy it if I wanted to but somethings niggling in the back of my head to leave it. Can't put my finger on it.

If I'm very honest, I'm waiting for the new Civc Type R to appear as I like the look of it from the magazine shots I've seen but obviously want to see it in the flesh and get a drive of it before I decide if it's for me or not.

Incidently, I asked about any plans for an Auris TS when I was in the dealership but I don't think the salesman was very knowledgeable as all he droned on about was how fantastic the new diesel engine for the Auris was!

The Compressor is actually a great car and it has all the trick bits the T-Sport should have had from day one.

There are one or two niggles with them but you have to accept that they were a limited run of a specialised car and they didn't have the time to put the miles on them for development, not good but it's what we have.

I am in constant correspondance with a guy at TTE who is sympathetic to the faults and is trying to help me out.

He has now recommended that I take the car in for a new ECU under warranty to sort my power problem.

So be it, I still love the car

hi chrisio dont no if you,ve seen my last entry having new compressor fitted but ask tte guy his veiws if pos. and despite my probs so far still think the car is great

[Chris.S]

Going be putting a K&N in mine nxt week and remove the air intake. engine cover goes for painting too.

Going to speak to a few friends at TTE as to the possibilty of fitting an intercooler

recommend the k n typhoon kit makes a big difference to performance on my compressor

[Chris.S]

just going for a panel filter for now and remove the intake

[chrisio]

I would be interested in the result, I can't see how the pipework would route ;)

When he mails me back I will ask the question

[Chris.S]

Those guys who have had their compressor a while now can i just ask if you notice when the lift comes in.

I spent ages last night giving mine some serious acceleration but i couldnt feel it kick in

Hi guys, I used to work for Inchcape Derby and I had a Compressor as a demonstrator. The above is true about the exhaust, and mine smiked more one side, but as correctly pointed out this is due to the flow of the gasses. What none of you have said is that although it box looked a bit strange on one side when directly behind (and low enought to see it) if it was pained black as per the press photos I saw, it was not obvious unless you know. I also wanted to add that I have had a few Corolla T-Sport's and none of them sounded as nice from the back, there's definately a louder note to the Compressors's system! With regard to the power band, I agree. I did about 5k in my demo and the powerband is smooth from 2k to 8.5k but there must have been increases, just not as 'vivid' as a normal VVTLi. You may all tell me to go away, but one problem I had was pinking from the engine. I got the Field Service manager from Toyota involved and we found that Optimax was the only fuel to use as well as the built-in re-map function set by TTE/Toyota. The cars cam mapped with 217 BHP as by law all cars have to run on normal 95 octane rated fuel. BP Ultimate is 97, but the requirement is 98BHP. I was tole to fun 2 full-tanks through it and then re-map. This was done by switching the engine to ignition-live (all dash lighgt on, but no engine) then holding the accelerator pedal down for 40 seconds until the engine management light flashes. Lift off the accelerator and start the engine. This re-codes the mapping to the originalo 237PS it was intended and removed the pinking (it may have been physchological but it definately felt quicker!)

Hope this may help someone if they've experienced it and I was really sorry when it sold :( . I loved it like it was mine but someone got a very nice (gently freed-up but quick) Compressor with additional wing 'TTE Compressor' badges I sourced by e-mailing TTE Europe and asking for some!

Take care all,

Will J

[Chris.S]

going try that later as im running v power all the time

you dont feel the kick now with the compressor boosting the air flow giving the engine alot quicker acceleration its smooths out through the rev band so you dont feel the kick

My name is Ben Rumsey and i work for Ipswich Toyota. i like will also run a compressor as a demo. Im a car freak and i have looked into every concievable option to get more from my compressor because when i first got in it i was unimpressed. Firstly, everyone going on about intercoolers, u dont need an intercooler, if you did there would be one. Your forgetting how powerful the engine is minus the supercharger. Secondly, the only air filter worth looking at is the KnN Typhoon but only because it wont give you flat spots, its no better than the standard system but it does make alot of difference to the sound. As will said above the best thing you can ever do to the car is reset the ecu mapping, Do a few thousend miles in the car using only V Power or Optimax fuel to really bed the engine in, its worth a plug and oil change before u do this as well but not essential. A technical instructor at the toyota training academy claimed to me doing this would give me up to a 70BHP increase. Toyota limited the car to much to start with but the second u reset the system it makes loadsa difference.

Wots baring in mind for all you type r lovers and clio 197 people, the TTe compressor is a far highly tuned system that just needs more coaxing than others. My car is completly standard, no air systems or tweaks wot soeva. All i have done is been a lil bit gentle of it for 2000 miles, changed the oil and the plugs, run it only on V Power fuel and reset the ECU. On a rolling road i hit 272BHP! Its a more hyperformance car than people give it credit for. And its for sale..... 06 reg in alsace granite 3650 miles, mint condition with £1200 genisis/vibe premium stereo £16395 call 01473 715777 and ask for me!

you talk total rubbish and all you want to do is get rid of your compressor on here with BS.

272BHP do you think people on here are stupid like you? everybody know the compressor on the corolla is NOT highly tune thats why it doesn't have intercooler and only make extra 26bhp more than t sport.

the toyota idea to supercharge the corolla was to help the 2zzge engine run smoother with more torque

at low rev which make it more driveable,it was never mean to be a highly tuned compressor system unit what so ever and if anyone is reading this and if you are going to tune a corolla best buy are a tsport cos we all know the tsport has a better future for tunning than any corolla compressor.

Hi guys, I was going to leave this now as it was starting to look silly. The info I gave I assure you is 100% correct from a TGB Field Service Manager. It's not official, but I am sure someone can substantiate it for me. I have to say that 272 is no-where close to what I was told. As I understand it from the people who developed the engine, the tie for TTE was the developement of this engine for Lotus as well as Toyota. I remember meeting the Japansese Corolla design team and an interesting chap called Satoshi Maekawa who asked me,'where is your Corolla Compressor?' I had never heard of this apart from an article in Autoexpress showing a German TTE developments 5dr Corolla Compressor which they said would never make it to the UK on price (I can't remember exactly but I think it was something like the equivelant of £24k at that time!!!) This was nearly 6 months before it was announced to the UK and even he said it was around 240 BHP! That and the fact that the forthcoming Corolla Verso T180 was being in-gear tested against a Porsche Boxter - and it wins!

The original specification of this engine is 237PS which TTE felt was as much power as can be reliably produced baring in mind the 3 year 60k warranty etc... Lotus kept the higher configuration but Toyota then re-worked the mapping to the eventual 217PS figure because of the legal requirement to run on conventional Unleaded (95 octane). 2 years ago, the T-Sport engine was the world's most powerful normally aspirated engine at 109 BHP per lite (more than a Mclaren F1 and BMW M3 etc...) which is today still quite a boast if you were not aware of that stat which I am sure most of you are! If you trawl the engine tuners pages, there is very little in the way of 'boost your Corolla T-Sports Power' trick modifications because it is developed to pretty much its maximum ability - of course Toyota could have got more (look at their 900HP formula 1 engines), but they managed a phenomenal feat just the same. As '215 Compressor' member rightly said, the Compresor makes up the difference below the Cam timing change, and I agree that it does smooth the powerband out albeit I kind of liked my previous T-Sport's 6,250RPM or so kick! It used to make people react more than my Compressor. We tried (unofficial) roll on's one day on a private(!) test track linked by hands-free mobiles against a 150 BHP Avensis. You may laugh, but the torque that engine produces is very impressive (pre t-180 days) and you'd expect the Compressor to anhialate it easily. It certianly overall was a lot quicker - but only after 5,000 RPM when the Avensis ran out of revs. The Avensis really did start to pull away on low boost from about 2500 RPM onwards. The suprise for us and the relevence of all this was when we got to the 6th gear roll-on. We set both cars to 50 MPH in Top and booted it on countdown. The Compressor not only matched the Avensis from the lowest revs upwards (real world remember as you may well do on the motorway if you have to brake for a lorry pulling out then change back into a faster lane without changing down the box) - and the Compressor carried on pulling away, before the significant difference on or around(!) the legal Motorway limits. I'd be interested if anyone here has tried a T-Sport against a Compressor doing the same?! I suspect if they have, the results will prove the Compressors superior low-down rev improvements, but would you answer the question that a well-driven T-Sport 'buzzing' on Cam through the 'twistes' would not be able to keep up with a Compressor? I doubt there'd be much in it would there with similar driver abilities?

Come on Mr 272BHP!!! ... if that's true, that's got to be some kind of TTE Technicians way of having a final giggle before leaving... let's see the scan for the Rolling Road because I reckon that the 237PS, as I understand it - is both Toyota and TTE's top limit... as well as the optimum for this car before silly expense!

Regards,

Will J
