Well 25psi definitely aint no joke. What turbo was this with?

Damn, that makes me uneasy about trying this, even with only 10psi :(

I think what you are proposing would be safe on E85. It would certainly be safe with W/I . . . do it everyday.

Of course, safe and being able to make max power are two different things. You will be down on power compared to a setup running the same boost with an intercooler.

BTW, you could use the SAE correction feature in Virtual Dyno to simulate the power difference. I'm planning to experiment with this. I'm looking for a bit more power and was thinking an intercooler would be my next step. However, that thread Curly started discussing his latest results and the subsequent discussion on restrictive exhaust systems has me thinking that my exhaust might be the low hanging fruit. Stay tuned . . . .

See that's the thing: I am trying to stay under 250 til I throw rods in there anyway, so my only concern is safety, not maximum power potential.

I definitely plan to throw an intercooler in there when I go past 10psi, just thought maybe I could maintain somewhat of a sleeper look for now and not bother with the IC

I know for sure I tried it with my EvoIII 16g, possibly with my PTE5027e. The 16g would spike to 32psi and settle at 27 and with an IC the heat was no problem, but IIRC it started knocking before I even made it to 20psi with just a hotpipe.

Why not just paint the intercooler black? I swear I read a study somewhere that said it made little to no difference if there was a thin coat of paint on an intercooler. Sport Compact Car years ago maybe?

Its not just the stealth factor, its the hassle of fabricating and installing one when I will be limited by stock rods for now anyway and don't need to make any more power than what the turbo will already net me at around 10psi.

seems pointless. egay intercooler is cheap and easy to install. fabricating is hardly a big deal. I can think of at least 3 very clean effective ways to mount without much effort and about $10 worth of aluminum w/ bolts...

running the pipe is a bit more of a pain in the *** but still pretty easy. A hacksaw & a washer welded to some vice grips + 1 to 2 hours of your time is not bad at all. total i/c project ~$150-200. I can think of a lot more worse things to waste money on. If you plan on building your motor eventually mite as well do it anyway instead of putting effort into something less effective.

Modify the cold side of your A/C to a box in your charge pipe, turn on A/C, use it to cool intake charge, win. No front mount, but a lot of fab work. Kinda kills the point.

Just guessing here . . . but I'll bet Vlad knows how to fab and mount an intercooler and has probably done it several times.

I'm sure. Just trying to point out that he's fooling himself if he thinks e85, some injectors, and w/i are any less of a hassle and cost saving.

lol yeah I've done this more times than I can count. Its not a matter of IF, its a matter of WHEN, that I want to do it. That's all. Trust me, I'm not trying to half *** it or work around it.

Right now I'm driving it daily, stock powerplant. I want to slit my wrists its so slow. When I get into it after my subaru, its like I'm driving in reverse. I'm so busy with other stuff that a full on engine build and big power is out of the question.

Which brings me to this: I want 200-250whp. As simple and basic as possible. If I make more than that, I will have to either lower boost or retard timing to keep the motor in 1 piece. So doing an ultra-baller efficient intercooled setup isn't really even necessary, because my turbo is big enough to pop the motor on anything more than 10psi

Anyways, I'm not shooting peoples ideas down, just trying to get a feel of who's done it and if its reliable enough to be worth it or will 200* IAT's still fry my pistons despite being on e85. In which case I'll just suck it up and keep driving the car stock til I'm ready to yank the motor and get serious with the car.

i'd feel pretty comfortable with w/i e85 @ ~200whp. I think it's very reasonable. I just think that i'd rather intercool, premium gas, stock injectors until i could get serious.

why use premium gas when I have e85? I'm not injecting w/i or e85. I'm running it.

my bad. i had w/i stuck on the brain after reading all that garbage.

begi claims 140-160rwhp with their s kit hotside @ 5-6psi. I say go for it. Would be a lot more simple and i could see why that option would be really appealing. DO EEEEEET. I don't know about 250rwhp but 200 definitely doable.... let us know how much you can get out of it

I don't see you having a major issue, you'll be down on power, but you can retard timing sufficiently to prevent det.

Myself and my old man have run MP62 and M45 coldsides with no IC or WI for years.

You'll have a much more efficient turbine helping you out along with the fancy uber high octane E85 fuel.

cool is there any thread that compares water to air vs air to air?

I once saw a thread about an MR2, I think it was an MR2, where the guy boxed the intercooler and fed the air conditioner into the box. Not sure if it was an A/A or A/W and he was chilling the water tank.

Anyone remember this or was I dreaming?

Water/Air is stupid. I'd never run it.
