Guest Budz86 Posted February 9, 2014 Share Posted February 9, 2014 Ok, so I know these are an essential part of a turbo charging system but what I'm wondering is how much of a difference a good quality unit compared to a rubbish, inefficient one is? Not in terms of price, but of performance. Interested in how much difference you guys have seen just by changing the IC? If you remember the intake temps too that would be useful Reason I'm wondering is because mine has no markings on it at all and I have a feeling it's pretty lazy! A change is on the cards when I can spare the cash but just wondering what sort of improvements I'm likely to see Quote Link to comment Share on other sites More sharing options...
Abz Posted February 9, 2014 Share Posted February 9, 2014 FMIC? Or you talking SMIC? I have fitted FMIC to both my Supra's and I'd say it 'feels' like it make a difference but that could be to do with something new fitted. Pretty sure it doesn't make a large difference to HP, but I am sure on colder nights it certainly makes more difference to when it was stock. No idea what the intake temps were dude!

imi Posted February 9, 2014 Share Posted February 9, 2014 i changed from a stock 10+ yr SMIC to a CW SMIC - and the difference was noticeable. documented on a thread on the forum - search is your friend. Quote Link to comment Share on other sites More sharing options...
JamieP Posted February 9, 2014 Share Posted February 9, 2014 This time of year it won't make a huge difference unless your IC is shot. Quote Link to comment Share on other sites More sharing options...
ccssupra Posted February 9, 2014 Share Posted February 9, 2014 Interested in this. My intercooler is out as its just in a very poor condition. Looking at a whifbitz or CW SMIC. Quote Link to comment Share on other sites More sharing options...
Pulley Posted February 9, 2014 Share Posted February 9, 2014 A well designed intercooler will be both free flowing and effective at heat transfer to the cooling air passing between its veins Often cheaper coolers can have poorly shaped veins which although may allow charge air to pass fairly unrestricted thru them , are less effective at heat transfer and may also be more restrictive to the cooling air passing thru it Although there are plenty of pretty well made/designed intercoolers out there that lack the high price tag the branded ones demand I also think that unless your running big power you probably wouldnt notice the difference Quote Link to comment Share on other sites More sharing options...
Tommy B Posted February 10, 2014 Share Posted February 10, 2014 On a very cold night and a dry road where it won't spin up as much at the back, you notice big time. Plus they look the part. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 10, 2014 Share Posted February 10, 2014 The difference is scientific and irrefutable. Ambient air intake temperature versus intercooler exit air temp drop. Air density is directly related to air temperature and humidity level, including altitude. Air density is directly related to engine power output. I won't bore people with the maths, an easy to use calculator is, for example,\available here: http://wahiduddin.net/calc/calc_hp.htm Basically a more efficient intercooler is "free" additional BHP. (My idea of free is about £720 plus VAT ) Quote Link to comment Share on other sites More sharing options...
jagman Posted February 10, 2014 Share Posted February 10, 2014 If the question is FMIC vs FMIC and cheapo EBAY vs higher quality manufacturer : In performance terms I found sadly very little difference , issues were found with pipe work heating air at low speeds that had a more profound effect than the FMIC itself Quality wise the aluminium used in ebay item was much poorer and prone to rapid surface corrosion Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted February 10, 2014 Share Posted February 10, 2014 I changed from a fmic to an oem smic and the only difference I noticed was the side mound saved me about 3-400 rpm of spool time . ( this was an na-t so I cut out over a meter of ic pipe too ) Quote Link to comment Share on other sites More sharing options...

( this was an na-t so I cut out over a meter of ic pipe too ) Exactly the reason I've gone for the Whifbitz SMIC for my NA-T Quote Link to comment Share on other sites More sharing options...
