TMIC upgrade question
(I watch a couple of boards, so apologies for duplicates to fellow multi-forum surfers....)
I was surfing around a noticed that couples of places offer upgraded top-mount WRX intercoolers (SPI was one and I can't remember the others) and realized I don't see much about this other than the TMIC to FMIC talks.
Are there any appreciable advantages to simply upgrading the stock TMIC if you're running stock (w/a Cobb stage 1 and catback exhaust to be specific)?
Thx in advance for replies....

We have tested .5 sec faster 1/4 mile times just by changing from factory to AVO TMIC. If you are running higher boost, added cooling capacity is never a bad idea. FMIC for the really serious up grades, but there are many connectors that can sometimes leak, and added lag(although minor if you get the turbo package right). We like to see upgraded TMIC, AVO or APS are good ones.

on the stock turbo I have not seen great gains to be had from any IC upgrade... < 10 hp... this will not equate to more than .1 sec in the 1/4 and probably wouldn't really be noticed... if your going to upgrade the turbo to something bigger then an IC upgrade will provide much larger gains and I would recommend a FMIC over TMIC.

Until your making over 300 horses you dont even need to think about a fmic cause it wont help you. Mrt aparently makes a real nice top mount unit. The reason you want to avoid fmic's until higher hp's is because all the extra piping forces longer spool-up time which is our enemy.

The whole FMIC on a stock turbo negatives need to stop. It's all false info.
The "lag" or slower spoolup time of pressurizing a few more feet of pipe happens in less then a second. You will not feel it.

True.
all it takes is a little basic math calculating the cfm and volume of piping added by the FMIC.

There is some really good info on turbo setups in past issues of sport compact. They go through all the math behind everything and all the terminology, blah blah blah. Well from everything ive read, there is a difference in spoolup time, pressure drop, ect, by using a fmic vs. a tmic. Now im not sure how valid it is in the real world, but on paper it makes sense to me.
