Is it possible to run 12-15psi through the stock top mount with some sort of meth/alcohol injection and safely make power? Ive been told that the top mount is worthless past 10 or 11psi but what if I add alcohol to that?

I've been debating this myself and would also like to know the answer.

Generally though, you'll probably get a response like "It's better just to go front mount" or "if you want to keep the TMIC, get the ARC"

I say just try it and watch your a/f ratios.

Well, my motivation for this is that my car isnt the prettiest FC on the road. Looks kind of beat up, but runs great. So Im gonna go for the sleeper look, and well, an FMIC gives it all away. So I figured I see how far I can take the TMIC on my way to a goal of 300whp.

well if you get the old school trust FMIC kit, it tucks the intercooler pretty far back into the bumper, it makes it hard to even see it....

but i dont want to sound negative, i would imagine you could do something on those lines of alki injection, or meth, you can also try using a mister on the intercooler to help keep it cool

I thought about that too, something similar to an EVO/STI

...but doesn't the STI run a top mount? and last I checked, EVO IC's weren't that hard to see

If you have enough meth injection you can run way more than 15 pounds of boost effectively on the stock top mount. BDC was running 30% (or so) methonol on his car with a stock top mount, had a reliable 25 pounds of boost and was still seeing 1300 degree exhaust temps.
He has writeups on fc3spro, I think.

Haha 15 is about the highest I would want at this point, until I get a rebuild atleast.

do you have some kind of management for the methanol? Also 300 hp should be achievable with the top mount i believe, i remember seeing people with numbers right up that alley just running 10 psi like 285 ish. with a street port it can be achieved with much less boost. Also check out nitrous spray over the intercooler.... hmm that would cool it alot my buddy is running that on his RSX. i plan on running a mister hook up to the windshield washer sprayer to spray the intercooler to cool it down. but like i said you should be able to see the numbers your looking for with the stock top mount, im hoping to

So you want to spray ambient temp water to cool down an almost ambient surface temp front mount intercooler?

Mindspin311

Can you not read? Im talking about keeping the TMIC and using meth or alcky injection

Mindspin311

I was referring to the intercooler sprayer

TitaniumTT

Can you not follow logic? I was asking Phantomkid who's talking about windshield washer sprayers.

Read BDC's AI Blog on TeamFC3S, should answer allllllllllll your questions

Mindspin311

Ah, my bad. I thought you were talking to me.

TitaniumTT

No worries.... but serious, check out BDC's blog. good info in there. hit 440RWHP w/a TMIC.... of course running a signature HBP brap brap brap

Phantomkid

well ambient or you can have ice water in the windshield container, i believe the water will help with heat exchange

Maybe with another turbo.

Not a chance on the stock turbo....streetport or not.


Even though BDC hit those numbers on a top mount, I wouldn't recommend it to anyone. Sure "it can be done" but around 250WHP, the top mount is a restriction. I mean, it has 2" inlets for crying out loud

Sure, with TONNNNNNNES of meth, lots of dyno time a decent sized turbo, you *can* push lots of power through the top mount. But at the point of spending well over 3K on the mods listed, why **** around with a 20 year old IC mounted directly over the engine? Just to say you can?

At that point you may as well just slap the front mount on and experience even more power from intake temps that are even cooler.

why on gods green earth would u want to keep that thing anyway........they should call it an interheater

I've ran 29psi on the stock top mount with combinations of water/meth injection.
On the stock turbo I haven't run more than 16psi with straight meth injection. Not optimal, but works fine; power levels do not drop off as boost pressure is increased.

That is a very good point. Just because it CAN be done doesn't mean it SHOULD be done.

jonesfromindia

just to clear things up, there is a member on here, 1990 GTx, hitting 341whp with a top mount.....

Whats not optimal about straight meth? It will cool better then water!

I run alchy on my car and I have a HUGE intercooler. I love the stuff!

TitaniumTT

I want to see pictures of your setup J-Rat, please. The were all removed from that thread. I;m doing something similar...... I think.

FWIW - bigger intercooler generally = cooler temps. Cooler temps + alchy = even cooler temps..... more ignition too
