I am going to run 3076's (~800whp) and the car currently has AWE Intercoolers. The car will be running on E85.

Now I am thinking I may need bigger intercoolers but will it not be as important if the car is ran on strictly E85?


Thanks!!

 

What are the dimensions of the awe?

 

It's like the same size as the USP intercoolers. Around 40% larger. 3.5 inches. But my impression with e85 it's less of a concern.

 

Well USP is making hp in the 950whp range, so if your IC cores are near the same dimensions as there's then you should be fine.

 

i think you'll be fine. awe says theyre good for 700+

 

e85 is a "better" fuel, but If you're tuning to its limits then you may get the same benefit from a bigger intercooler that you would with gasoline. The intercooler's job is to reduce detonation by cooling the compressed(more energy/heat) intake air, so if you're making lots of heat on e85, it has the same application.

On two cars with identical setups, but one is e85, the intercooler would be working less hard on the e85 car. This can't always be applicable though, because an e85 car would generally be tuned more aggressively due to e85's race-gas-like properties.

 

Not exactly...

E85 isn't a "better" fuel, it's just different. It's a less efficient fuel in regard to mpg, but has superior cooling properties vs regular gasoline.

As far as the intercoolers are concerned, they aren't working "less hard" on an E85 car vs gasoline car. The intercoolers receive the same charge air in both situations, and have the same limitations. The difference with E85 is the advanced timing you can run before running into detonation, and that is entirely where the added power comes from vs gasoline.

 

You'll be fine with the AWE coolers. That's not saying you wouldn't see a benefit by running even thicker intercoolers, but you certainly don't NEED them.

 

I suppose the " " around "better" wasn't enough.

My point was ethanol burns "cooler", but you end up using more of it. The fact that the ethanol will make more power in general results in higher temperatures.

As far as my identical setup example went; it could have been worded badly. I meant that the ethanol car would use a lower boost with more timing, so the intake air temp would be lower.

 

..Agreed..

 

Ok cool, thanks guys. I'm assuming my other mods come into play also inrealtion to detonation and heat, More air flow less heat?

 

I think Tim said he's using 3.5 in core ic's, and he put down 1300 whp.
The awe coolers will do you fine, especially with e85 since the it runs cooler.
