View Full Version : TMIC on a DSM? Crazy!

You're forcing air into the engine bay behind the radiator and increasing the overall air pressure in the engine bay. This means less air will be going through the radiator.
I don't see how it could be much worse than putting a big FMIC right in front of the radiator though, Subaru's seem to do it without cooling issues, but then again I don't know much about aerodynamics either

Actually, I think it would work just fine, probably not for serious power though. Now if you did some kind of ducting below it and around the tranny with a suction fan, now you'd have something.

Sounds like it does have some ducting, but ya probably not for any serious power.
The fan is shrouded and pulls down. It is a radiator fan from a honda Civic and pulls a great deal of air. With the scoop removed you can feel air being drawn from a couple inches above the intercooler.

i think this would be great for a mean street car, and i think it would help smaller turbos trying to fill aftermarket intercooler piping, might not be a huge increase but should be decent, then running meth if you really want bigger

His outlet temps are horrible. Air temps above 130 degrees are quite bad. A decent setup should be be 80-110 degrees at 70mph with ambient temps of 76. I have only ever seen 170+ on non-intercooled cars.

Sounds about inline with Subaru temps. We all know how great those are ;) As Shawn said, there is a reason Subaru guys go with FMIC setups instead.

nvm me then, thats f-n horrible, i never knew much about intake temps till now, guess you learn something every day

Yup, crap tastic. I got temps up in that range (170) running 18PSI on my stock SMIC's. Now with my over sized FMIC they are about 15 degrees over ambient at about the same boost level.

I remember seeing a guy Running E-85 and no IC on a DSM with a very large turbo(20g i think) running only about 16-18psi to keep the temps down some and did very well knock/intake temps. I thought about short routing my Stealth for one day with E-85 but after feeling my intake air temp coming out of the bov after a decently long day.... i started to think maybe it was a horrible idea.
Gotta admit, you don't see a TMIC very often on cars other than subby's.
Better than this car(Weird use of a DSM SMIC):

Or this one(TMIC on a Civic FTW!):
