kill1308 Posted June 25, 2009 Share Posted June 25, 2009 Just curious really.... Is fitting a decent FMIC likely to give a half decent power increase over the standard SMIC? I know it's the case on several other types of cars, but I've heard that the SMIC on the supra is pretty good (given it's in good condition). Also assuming it's a decent quality FMIC with well designed endcaps. Has anyone ever done a before and after test power wise on a BPU car with FMIC vs SMIC....? I did a quick search but couldn't find anything conclusive Anyone got any ideas on power gains (or losses due to re-routing of pipework possibly causing heat issues from elsewhere?)

pistonbroke Posted June 25, 2009 Share Posted June 25, 2009 I think from whats been posted before, that there is no advantage to having an FMIC unless you go single. Quote Link to comment Share on other sites More sharing options...
Ark Posted June 25, 2009 Share Posted June 25, 2009 The definitive answer is: "It depends..." Most of the gain is down to replacing a knackered old IC with a new one. Quote Link to comment Share on other sites More sharing options...

kill1308 Posted June 25, 2009 Author Share Posted June 25, 2009 So do you think it's worth getting one then if it's not in good shape? Or would it be better replacing it with a new SMIC? Quote Link to comment Share on other sites More sharing options...
tDR Posted June 25, 2009 Share Posted June 25, 2009 I had a good condition SMIC and my car definately 'perked up' when fitted with a GReddy 3-Row FMIC. Make of that what you will! Cheers, Brian. Quote Link to comment Share on other sites More sharing options...
SupraGirlie Posted June 25, 2009 Share Posted June 25, 2009 only of use if your SMIC is knackered on a BPU Mine was really knackered, also BPU, and I have noticed a difference with my new Greddy 3-row Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted June 25, 2009 Share Posted June 25, 2009 (edited) In a word, no, unless your SMIC is turning to powder. Remember the Stock SMIC has proper ducting going to it, which brings its efficiency up dramatically,. I would say 90% of the FMIC's fitted to Supra's are not ducted properly or even at all therefore they perform worse than a Stock Good condition SMIC.

Guest Budz86 Posted June 25, 2009 Share Posted June 25, 2009 What does everyone think about the different brands of FMIC? Is one brand likely to produce better results than another? I'm assuming here that they are well known brands (HKS, G-Reddy etc.) as opposed to the el-cheapo ones one E-bay Quote Link to comment Share on other sites More sharing options...
jazz1 Posted June 25, 2009 Share Posted June 25, 2009 It does give an increase il post the thread later, a guy did a dyno before and after fitting the greddy fmic and had increased bhp on stock tt Quote Link to comment Share on other sites More sharing options...

With respect thats a load of rubbish. supragirlie's car is markedly better with the Greddy FMIC and i have never known a car to lose performance. Look at the surface area thats in the cool air compared to a SMIC with a load of leaves and the odd dead hedge hog embedded in it, also factor that the pipework is prob better on a FMIC. On the other hand i could allways put Nells old ic on my single and see how well it goes!!! Quote Link to comment Share on other sites More sharing options...
kill1308 Posted June 25, 2009 Author Share Posted June 25, 2009 Seems like there's 2 differing opinions on this so far then... I'd be interested to see what more people think about this too. Would be nice to have some numbers to backup any claims but understand that's probably not possible. Thanks for your input so far peeps, appreciated...

ClaireRZ-S Posted June 25, 2009 Share Posted June 25, 2009 I change mine because i have a do luck bumper and i hated the gap , the car seems to be a bit quicker since it got installed but thats just me. Quote Link to comment Share on other sites More sharing options...

But what condition was Nells SMIC in, thats the point New for new on a BPU car a SMIC would be as efficient, fully ducted and lighter, add that into the fact it does not restrict the air flow to the rad Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted June 25, 2009 Share Posted June 25, 2009 I thought the general consensus was that fitting an FMIC to any turbo'd Supra would give an increase in HP, at the expense of a little Lag. I can't see there being much difference in lag however, as the stock pipework look far more restrictive than the pipework supplied with the Greddy and HKS kits, even if the aftermarket stuff is a bit longer.

MarkR Posted June 25, 2009 Share Posted June 25, 2009 I put the Blitz IC on and it is pretty large. Afterwards I noticed a little more lag. No noticable gain in power. No dyno I'm afraid. Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted June 25, 2009 Share Posted June 25, 2009 (edited) Fitting a bigger intercooler won't raise power on it's own unless you up the boost a little to compensate for the higher amount of cool, dense air going into the engine. The boost should drop a tiny bit if the intercooler is doing it's job properly, yet the engine will make the same power. It just has to push less air to get the same result. Hence a power increase is seen when the boost is brought back up to the same level as before, because you're actually getting more air (denser) flowing into the cylinders. The above is only true for comparing two intercoolers in exactly the same condition, so isn't the case with most of our cars.

kill1308 Posted June 25, 2009 Author Share Posted June 25, 2009 So by that logic a BPU car with increased boost should technically gain a bit of power if the inlet charge is being cooled more efficiently? I know the standard one is well designed and situated, I just find it difficult to understand that fitting a larger intercooler with solid piping wouldn't increase power somewhat.

Terminator Posted June 25, 2009 Share Posted June 25, 2009 (edited) The standard SMIC in good condition is the best option where only modest powergains are planned. An uprated SMIC will take you up to 500bhp of mods. Most people, fitting an FMIC as a replacement for a shot stock SMIC, may notice some power improvements as the charge temp may be being brought down to where they should have been. Bigger FMIC's just help achieve the potential of other mods. Edited June 25, 2009 by Terminator (see edit history) Quote Link to comment Share on other sites More sharing options...
