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. :P

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.

shaun.

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.......

intercooler is not a power upgrade on its own!

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.

s.

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

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)

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.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
