Default Will I gain powah????

Okay, I was thinking about FMIC's (Mostly due to the last post) But was wondering, I have a crappy Ebay front mount (22x9x3) now...if I where to switch to say a Bar/Plate Full-Race FMIC (20x11x3 rated for 700whp) and run 3" cold side piping would I pick up any power??? Stupid question but I'm on the quest for 400....no 500hp on pump with this little ol 1.6 ...

nothing noticed by your butt. The bigger intercooler may cool the intake charge more efficiently and may be able to bump some timing.

um what turbo are you running? cause maybe a bigger turbo will get you past 400 as you seek with the same 25 psi. I think eliminator runs something like 26 or so psi and makes 500 someodd whp.

I doubt you'll gain significant power

I believe you will gain a worthwhile amount of power. Not from the cooling of the intake charge but by the less restrictive flow and lower pressure drop. precision 750 is ftw.

I'm willing to bet they are both sourced from China, and you will see less airflow to the radiator as well.

In my opinion, I think you should start to look at displacement first for power. Judging by your profile, you've invested some $$$ in a 1.6....but in order to reach the 400-500whp range, money is probably better spent on engine displacement. Of course this isn't factoring how much $ it'll cost to build up a 1.8l long block, swap parts over, etc.

The biggest offense IMO on an eBay IC is found in the end tanks. A good IC will have a proper transition from the inlet to the tank. The second would be the entry into the core at the bar/plate ends. Look for Brainy's thread on his new eBay IC- lots of details there.

I don't know what the technical differences are bewtween the two intercoolers but that's a difference of only 66 cubic inches which is only 10pct difference. Offset that with pressure loss and it could be a wash.

I put up a thread recently asking if a small intercooler with WI could function well for high hp situations. The consensus was that with WI a small intercooler would be efifcient enough.

Have you considered WI? The cost of that intercooler would be close to the cost of WI with safeties.

Also plz do tell us what ur turbo is . And my vote is to keep ur 1.6. As for eliminator, he may be running a stroker but he also has great intake and exhaust manis, good spark etc etc so its not apples to apples.

Frankly, your reccommendation sucks. Why don't you give him the thousands of dollars required for that extra little bit of hp?

Are you running the stock intake manifold? if so good job! I would also like to know what turbo you are running.

The endtanks are fine, it's the transition into the runners which leaves much to be desired:




see how they protrude past the plane? that's the downside of tube and fine, otherwise they hold the advantage over B&P.

Before replacing the intercooler, maybe give some thought to how much air it's getting.

Whoops, misread it. If he's only going for another 20whp, yeah, 1.8 build isn't worth it.

Ive finally got you guys to where you accept it and are willing to try it that is all i ever wanted. If he has been on this forum any amount of time he should know about WI by now.

I have a T3/60-1 turbo, I'm debating on which turbo to go for maybe the new Billet wheel from PTE 5758 with a .63 hotside. I know there is no replacement for displacement, well my theory is that boost is the replacement. I have seen D16 SOHC Honda motors make over 600 whp on a head that doesn't flow that well. I'm going to run WI soon, also. I have a Flipside Customs manifold with 70MM TB just have not got the chance to put it on yet...

Replacing displacement with boost means you have to wait longer for your power. If your motor is built and you have no problem waiting til after 5k for full boost I say throw in a giant slug, crank up the boost, and lay pipe like hustler

You're right, yeah my motor is built...I really don't care about lag, and I don't get full boost around 4,500 already. Lag is really a good thing, I don't have to worry about traction issues so much! My problem is I cannot decide on what turbo to go with.
