Stock SMIC ducting and heat soaking fixes?

[my_precious]

I was working under my car yesterday and realized, as most of you already know, that right behind the passenger side fog light there is the intercooler ducting. I know that when pushing over 16psi on the stock SMIC you run the risk, and probability of heat soaking the intercooler. So I was thinking, with removing the fog light how much will this help? Obviously it would only help while the car is moving. Water injection and fans are another option, but when a Supra side mount intercooler is only 100-150 bucks its really not worth it. Is there any other way to get air through the intercooler? I know you can cut the splash gaurd and make more openings so air can get in easier, or rather get out. I have thought about if for a bit and I have an older book "turbochargers" that I've been reading and I know there are some tricks to get your turbo running cooler. However, I dont think much can help with the stock SMIC and that the cheapest and easiest most sufficient way to go about things is just upgradeing the intercooler all together. What do you guys think? I did some searching but didn't find much on the subject other than what I've already said.

Thanks,

Zach

Smart book.

FYI.. the foglight removal is stg0 in the Tuners Tunign Guide

I cut a square hole in the bottem of my ducting to my stock sidemount and JB welded a plastic scoop. I painted it and it looked pretty cool hanging from under the car, actually . At 15 psi, it did cause my intercooler to heat soak later, as I could do more WOT pulls;1 before and 2 after. But that's about it. When I raised my boost to 18 psi, there was no difference. So I got a water/alky kit.

Alky, it's not just for drinking anymore

I remember wayyy back DejonTool used to offer upgraded inlet/outlet pipes of the stock SMIC to 2.5" which proved to reduce pressure drop thru the core 3psi.

Assuming the 14B is at 74% efficiency, that equates to ~25F increase in compressor outlet temps at the same manifold pressure of 16psi

That's a good point! Pressure drop forces the turbo to worke harder to get to your desired boost level. And if you're running at the edge this would make a significant difference. True intercooler efficiency includes pressure drop not just how well it cools.

BTW, I figured alky worked so well in me that I thought my car would take well to it. It's now my drinking buddy ! (no I don't drink and drive. I drink and mod.)

you can always true methonal injection

With the outrageously low prices FMIC cores are going for these days, there is really no reason not to get one and fab up piping for under $300. Do the job right the first time.

But water/alky injection is such a cool toy to have, it's on my wishlist before summer hits. Plus some people just don't want the FMIC. But your right, the cost of a FMIC plus piping has gone down a lot. It just depends on your goals.

An aside, kinda cool to see some of the fastest turbo cars out there are not running any Intercooler at all. Pure Methonal Injection

Well i have dejon tool 2.5 inch upper and lower pipeing. I thought about aquahol injection (as the book calls it ) but you have some major issues with that like if you forget to fill it you'll toast the pump or if you dont have 50/50 it'll freeze in the cold, and there were a few other things like if you dont have a manifold pressure? switch (some kind of switch dont remember) it can over pump it into the engine and you can water lock the pistons. Water injection is suposed to be avoided unless absolutely necissary the book said. As far as the intercooler goes though, whats the most psi i can run without getting heat soak at all? A supera SMIC is only about 100-150 bucks so i should be able to get one soon enough, running stock boost will be a huge upgrade to what im driving now anyways...

You need to research alky injection a bit more and stop referring to "the book" as much.

the book is a bit old and probably new things have been found or new technology has been aquaired. however, i think a water injection setup will still cost more than a supra side mount intercooler. I basically bought this thread up because i was wondering if there were any "free" mods you could do to get more air to the intercooler, or how well removing the fog light would help. the other thing was, maybe i could make a water injection system from the window washer fluid pump (as in the book and i've also read here) for next to nothing. Since it is winter right now, maybe i dont really need to do anything to cool?

the other thing was that i only want to run about 300 hp for my MAX goal as of right now. i am on a low budget and dont want to buy a bigger turbo, intercooler, injectors, etc. I just want to run the most power I can on the stuff I have and maybe buy a few more thigns down the road to get closer to that 300hp goal.

If you were wondering, right now i have:

Dejon upper and lower intercooler pipes
K&n filter
various free mods, includeing a removed back seat and carpet
14b turbo with no shaft play (bought it used a few weeks go...car came without a turbo)
ACT2600 clutch brand new never been used (already installed with car)


I'm also running the stock SMIC as you know, and stock fuel pump, injectors, etc. I dont think i have anything else upgraded, but i cant remember... I have the money and I've researched it alot so I have a 3inch stainless (o2 back) custom exhaust planned for the future.

i have a lap top. right now the car isnt even started yet. i was just thinking of things i could do to the intercooler while i have the car in the air. as for the fuel system, i should be able to run either a rewired stock fuel pump or a 190lph as far as i've read/been told. like i said, 300hp is my max goal, so working up to that point is a given.
