TMIC on a DSM? Crazy!

[CVD]

I'm skeptical of anything that allows air to enter the engine bay without passing through the radiator. DSMs have cooling problems enough as it is.

How do DSM's have more of a cooling issue than other cars?

They tend to make more power than other cars.

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

As posted earlier I got some data on the efficency of my intercooler. I have done some Research Diving in the past and was trained to collect scientific data for study. 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!

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
