Re: TMIC on a DSM? Crazy!

Supposedly he's getting 2-3psi by 1800 with the piping that short. If that's truly the case, fuck anti-lag.

Re: TMIC on a DSM? Crazy!

why not just run no intercooler like crazy said with meth. Its been done and works. Now that will be the best system with the least amount of lag

Re: TMIC on a DSM? Crazy!

Maybe I'll sell my front mount and use that money to buy a meth kit. Then get my 16g back and run 30psi til redline. Sounds like a plan to me!

Re: TMIC on a DSM? Crazy!

I had piping that short in the Colt when I had no intercooler. I didn't notice significantly slower spool when I added a sidemount IC in the stock DSM location.

Re: TMIC on a DSM? Crazy!

No intercooler would be nice.

Re: TMIC on a DSM? Crazy!

IDK, this looks like an awesome idea to me, it looks like an old guy is doing it too which more than likely gives him no reason to lie about how welll it does or doesn't perform like a younger person might do. It limits the size of intercooler sure, but it's original, very well done, and as far as we know it performs well. This guy has made a whole bunch of cool shit right in his garage too I think its pretty cool what he's doing

I don't get it, he moved the intercooler, the radiator didn't move....

EDIT: more info I found on the IAT's

But I was not tought to interpret it. I do know that the data collected is not good data. there were to many inconsistancies to be accurate. All were done on a long highway on ramp and posted speed was not exceeded. But traffic made it difficult to repeat experiments and the low speed ranges are passed by so quickly it was difficult to lock the temps at the right time to get good readings. I did learn one thing. I need a cold air intake system.
The first test was acceleration and highway cruise no boost.
outsid air temp 76 Deg
mph - inlet temp - outlet temp
20 - 131 - 91
30 - 135 - 97
40 - 135 - 95
50 - 144 - 93
60 - 147 - 93
70 - 161 - 100

15lbs boost
mph - inlet temp - outlet temp
20 - 248 - 131
30 - xxx - xxx
40 - 262 - 138
50 - 257 - 134
60 - 302 - 159
70 - 331 - 174
These were averaged after several runs and I was so unhappy with the difficulty of getting acurate data that I forgot to test with the water sprayers on. I will do some testing again late at night when there is less traffic and I can get some more consistant data.
Also I was WRONG on the temp drop at idle. My data is collected in celcius and I have to convert to farenheit. My calculations were wrong the average temp is 10 above ambiant but will not go above that even idling for ten minutes.
I promised good or bad I would post the numbers so here they are. Tell me what you think!

Re: TMIC on a DSM? Crazy!

This isn't exactly new, even on a DSM. Luckily my daily hooptie has a TMIC from the factory, it must be cool!

Re: TMIC on a DSM? Crazy!

I'm having a hard time with this, it just gives the intake track a big piece of aluminum to heat soak. There's a reason Subaru guys go to FMIC when they start to make serious power (yeah I know, those two don't go well in the same sentence together), then again I also have an FMIC big enough to smuggle Mexicans across the border in.

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.

Bahahahahaa
Anyways I think it would be even better with a co2 spray kit on the tmic, that would be some serious air cooling.

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

Re: TMIC on a DSM? Crazy!

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.

Re: TMIC on a DSM? Crazy!

Sounds like it does have some ducting, but ya probably not for any serious power.

Re: TMIC on a DSM? Crazy!

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

Re: TMIC on a DSM? Crazy!

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.

Re: TMIC on a DSM? Crazy!

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.

me too

Re: TMIC on a DSM? Crazy!

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):
