Post Intercooler Kit - Problems?

[krush]

hey all,

over the passed weekend i installed an intercooler kit myself in my r32. a few dramas but it went in alright. the problem now is that it doesnt feel any better, even somewhat worse.

after a drive i feel the end tanks of the intercooler, the intake being hot'ish and the outlet being very cool, so im sure the air is actually going through it, and theres a noticable amount more lag, but it feels asthough its lost a bit of power. i used to be able to chirp second (gts4) but cant even do that now.

that might not be the best measurement of power, but from everyone thats installed an intercooler, theyve said theres a noticeable difference, even my mechanic mentioned one he isntalled on an auto had it spinning first whereas it couldnt prior to the install.

can anyone think of maybe some common problems, something i may have overlooked, something this or that? im sure everythings on right.

intercooler is not a power upgrade on its own!

What supporting mods do you run? It may need a quick dyno retune if you have an aftermarket air / fuel computer.

I put a fmic on 2 weeks ago onto my Stagea, and it definately needs a retune of the SAFC.......

sorry sorry, i also have a podfilter, cat back exhaust, (batmbl dumppipe is going on as i type this), iridiums (gapped at 0.8 if that makes any difference), running stock boost (which peaks 12 and settles at 9psi).

it feels like i had better performance with the smic on a cold night then i do with the fmic on a cold night.

power comes on more gradually with a fmic cause there is more air between the turbo and throttle body but at full throttle higher in rev range u may have a bit better power but less ability to chirp so push in the back can seem less but still have more peak power

[shif_tea]

just allows u to put the boost pressure up more man. Get a boost controller or bleed valve or something, then you might feel the difference.

response will be slightly worse with a FMIC however

FMIC is a supporting modification , it will allow you to make more power later on , IE higher boost levels

[paulr33]

as all the others have said. when you just fit a fmic you wont gain any power or less any. but you will loose throttle response. ie: more lag in the throttle system as discussed many many times before. fit a boost controller and an exhaust now and youll gain much more than last time and response will be great too as you make the outlet system more efficient (bigger exhaust) and inlet system pump more air (boost controller)

dude sounds like snail too small, cooler too big.

what is it - 600x300x76?

Consider that a factory GTR runs a similar size cooler to this and it is happy up to 300rwkW

there is no point changing the cooler unless the mods you have are struggling with the stock cooler.

[LANFOH]

A cooler on its own wont give you much gains however if you bump up the boost and free up some flow with some flow with an exhaust etc if there are no leaks you should really be able to feel it. Another thing is when I installed my fmic my car was running very rich this robs alot of power also, so a tune mite do you good eg safc or power fc.

okidokies,

well i have a full exhaust now, and it does feel more powerful and responsive (especially mid range for both), but also at the same time, feels its holding back a little.

the intercooler is 600x300c75.

boost also still drops off top end. i thought it was the stock -restrctive- intercooler that caused this. still doing it. makes me wonder if theres something restrictive in the new setup.

i might throw it on a dyno, im thinking theres too much little things to figure out by explaining it all :(

thanks very much for the input people, greatly appreciated.

shaun.
