Intercooler for AutoX

[andrewjscott]

Well, autocross season is almost over and I've been noticing my spool time is gettin longer and longer. I did a boost leak test and turns out the old stock SMIC is leaking, pretty bad too. The car is strictly used to autocross, currently I am still on the 14B but possibly looking to upgrade to a T28 in the future. So I need an intercooler, looking for fast spool time and was wondering what kind of lag people get using small FMIC's as opposed to something like a Supra SMIC, or perhaps even stock replacement.

correct me if im wrong cause i only know what ive learned by reading on these boards but wouldnt it be pointless to get a t28 for a first gen? Especially when a 16g which is better will bolt right up as a direct replacement

no he wants a fast spool up time and a t28 does just that

I would advise against a stock replacement for a T28. Mine heat soaks very quickly during hot weather, and if you're going to do a turbo upgrade and move up to SM you might as well go all out. A good sized intercooler will not hurt your spool-up noticably, especially if you are raising the boost--the gain in horsepower from not knocking will easily offset the slight delay in boost.

To back this up, the guys at http://farnorthracing.com/ are doing pretty damn well with a FP big28 and a griffin fmic core (28x7)

oh, i see. Sorry hehe.

I'm running a custom core right now (15x6x3) with super-short route I/C piping on stock turbo at 1 BAR (14-15PSi) and spool up is pretty quick as compared to stock I/C and rubber piping. I have a 16G that I'll be putting on with a ported manifold and O^2, all of which are from an Evolution I.

And yes, I do Auto-X.

ok, I'm leaning toward small frontmount with short route piping.

What kind of inlet/outlets do you have on the IC?

Also, are the ebay IC's any good? or should I shell out the money to a reputable source to get the good stuff?

I autoX a lot and have an evoIII and a supra sidemount. I never heatsoak on the street or the 1/8 mile drags. But on autoX courses with a lot of wide open throttle for long periods of time I do heatsoak, on tight course's that just use short burst of throttle I don't have any heatsoak issue's. So far out of about 20+ autoX's I've done on the supra intercooler I've only had heatsoak problems twice.

I am however going to switch to a front mount over the winter. This is partly because on the heatsoak issues at those two autoX's and partly because of other goals I want to meet at the drag strip.

If the original poster does decide to go with a supra sidemount and does experience heat soak issues, you could consider some sort of sprayer. Although, he is using an evo 3 as opposed to a t28.

I've yet to run an autocross where I heatsoaked the IC, but then again being fwd I can't be on the gas as hard or as often as you awd guys can.
