My Project 4.8 Turbo Fox Body.


I know some of you are doing intercoolers and some are not. I know the IAT's seem to be all over the place.

Maybe im not thinking this thru all the way but if your injecting E85 into the motor thru the injector how irrelevant is the IAT reading thats coming from a charge pipe.

basically how much is E85 cooling the air when its mixed in the intake runner ?


I was planning on running the large ebay special $75 intercooler but if it turns out to be a restriction after 500hp ill have to pass on it.

The problem is its hard to monitor IAT temps in the runner after the injector with an EFI setup. Some are doing it with success without an intercooler and its hard to argue with stock shortblocks living and fast quarter mile passes. Personally, I run an intercooler and E85 and wouldnt do otherwise unless it was blowthrough.

As a rule of thumb, don't do it. IAT's are inconsistent and could lead to subpar or inconsistent results. The intercooler is the cheapest part of a turbo kit. Why would you not get it?

I'm going to run mine non intercooled. Most people that say that you need an intercooler with e85 have never tried it without one because they were told they "need" one. The few people that have gotten rid of their intercooler say they would never go back to one. It makes me think of how people say ebay turbos are junk, can't make power, and blow up immediately. Those are the people that have never tried them.

Just wondering if the el cheapo intercoolers are a bottle neck on 500 plus horsepower.


I've been following denmahs thread about removing his intercooler.


Of course I don't wanna spend the cheese on name brand 800hp rated intercooler that most likely is not budget oriented.

I don't run an intercooler with my junk. I run E85, E70, and even E50. I added a 50/50 mix of methanol/water injector for my intercooler. Most E85 guys don't think meth injection is needed with E85 and so if that is the case then why would you need an IC. I put a AIS meth injection on it and use windshield washer fluid and a little extra methonal and spray it at 10lbs of boost. Car ran pretty damn good with it.

I don't have any experience with an IC so I am only commenting on my use without it.

I have the "el cheapo" 12x24x4 intercooler and make well over 600. My good buddy who is also a member on here and number 5 on the 5.3 HP list has the same intercooler. He made 808 the last time it was dyno'd and probably makes more now.

I'm just saying... It is easier to have it and decide to remove it later, than it is to not have it and wish you did.

I have no regrets. I don't have to spray meth, and I can run it back to back to back etc with very consistant IAT's.

BTW you can buy that intercooler by itself for 150-170 all day.

Meth works great, but costs a lot more than an intercooler and you have to refill it/buy more methanol.

Cool , do you have a link where you bought it from ?

I was looking at the 3" $75 cores.

Wicked69

Im not sure it costs more. I bought 12 gallons of washer fluid and used 2 gallons over 7 months. What I do know is the meth will not be a restriction and most IC's on a budget are. JMO

I got mine from my huron speed kit, but this is the same exact intercooler

I had a impeller let lose on me and send the blades right into the ic. Wo the ic my engine would have been toast.

I have done this with good results
stock LQ4 with just a big cam
S475 on 21# and about 12* timing
was somewhere in the 850whp area from what I could tell. It worked good up to 14-16# but was very touchy over that.

I have the ebay 12x24x4 cooler, I cut the 3" inlet and outlet off and moved it to the middle of the inner cooler while increasing them to 3.5". I had an old sbc blowthrough single turbo setup that went 8.4x at 164 with a shitty 1.43 60ft with e85. So the ebay coolers can support decent power. The car weighed 3760 before that pass. I now have a cam only lq4 and made a high gear pull with and without the cooler. With the innercooler my a/f was 11.1 with out it, it was 10.0. This was night time air and about 50 degrees out. If the car needed that much more fuel it must work pretty ok. The innercooler is back on the car. This was a blowthrough setup also.

I've run non-ic e85 set-ups. Hell I tried blowing up a 200k+mile auto bone stock dodge neon with a 60trim 13-14psi, e85, only pulling ~0.5* timing at 13psi. 200*+ (only could read to 200) iats zero issues. Even did about 40 back to back 20-100mph pulls on a 90* day trying to blow it up. Nothing.

What is the advantage of not running an intercooler?

I’m running a 5.3 with twin GT35’s at 17lbs on E60. I run water/meth inj at the inlets of the turbos. Runs great.

Depends on the power goal, back pressure, base compression, RPM, cam, loads, gearing, tune, etc…

Similar results for me as Forcefed86, i'm running twin 7665 on 5.3 havent had water/meth on it yet but will this year. I've run IAT as high as 250* with no signs of trouble so far. many passes 1/8 mile at 18psi boost.
