Intercooling solution

Long story short I recently bought a big block E85 ProCharged 72 Chevelle. The previous owner had the motor rebuild a year ago and in one racing season used it up running high IATs and no intercooler. Its running aprox 20psi and est 1500hp. Its being rebuilt and my motor guy says he wont even dyno it until its intercooled as that's the only way to get any longevity out of it at its current power level. Its streetable and I want to keep it that way so running methanol isn't an option.

Whats the best solution you guys have seen? I searched and didn't find much at all when it comes to mounting a FMIC in a 72 Chevelle. I would like to stick with air to air as its the least expensive option if possible.

Re: Intercooling solution

Have you thought of meth injection? As long as everything works, it might be superior to a intercooler.

Re: Intercooling solution

Run it on E85. Next best thing if you can't handle using Methanol.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

BIGOT is a word used by people that can't use logical reasoning to prove that you are wrong when you don't agree with them.

I ran meth injection on my last car (supercharged LS3), saw some improvement but ended up adding a water to air intercooler to get the desired results.

Its tuned and running on E85. I have all of the previous owners racing data. Its run with a Holley Dominator and he gave me the laptop with all of the data and, even on E85, the IATs were really high running the stock intake off of the ProCharger.

post 32 of 87.


I relocated the radiator back 2 inchs and mounted a 4" thick intercooler in front of the radiatior. It is a really tight fit with approx. 1/4" clearance or less in most spots. Only need to radius out the rad support for the charge tubes, nothing more. Core size was 24x12x4, should be good for 900-1000hp. generally anything over 1000-1200 most switch over to the water to air setup, use a small Honda radiator in front with a electric waterpump driving it.


With my FMIC setup I do not see over 100F IAT. most of the time I am between 80-95F. Only time it rises over 100F is a heat soak in the staging lanes, usually a burnout will get it under 100F, or throw the electric fans on.

That looks like the direction I`ll be going. Thanks.

i have one added to front of rad support;
i had to carve/cut away some grill supports,
and eliminate most of the center support the hood release was attached to.
it is the procharger 1050 hp unit with 3.5'' inlet and outlet;
it is about the same size as the radiator, but it fits now

That's what I was afraid of, cutting up the front to fit a large enough air to air intercooler. Any issues with coolant temps?

Found this guy, its a Nova but his air to water setup looks doable. See anyone use something similar in a Chevelle?

Im running the F1-X. Here is a pick of my current setup. Everything fits under the stock hood.

i have a fibre glass L88 hood secured with hood pin/locks on the stock hinges; the stock latch assy. c/n be used and was removed for room.
the coolant temps got hotter when i reinstalled the stock wheel wells;
i had to get the initial timing right along with a 71-72 style fan shroud and large mechanical fan w/direct drive off the waterpump;
i also got a 3-row champion radiator;
temps are so good now i even removed the aux trans cooler from front of radiator.
just using the internal trans cooler in radiator.
out here in the desert with ambient temps of 100* the car runs @ 180-195* with a 180* hi flow thermostat...
with a hughes custom 3900-stall torq converter

Define "really high"?
