here is a pic of one of two cars from the mid-atlantic i-club meet that had fmic conversions, among many other mods. fyi for those curious about this mod:

I'd be interested to feel what the low end losses are like with systems like that. Theory and all says one thing....but to actually feel it on the butt dyno would be another.

Geez....you'd think that was an STi.....fog covers, front grill.... ;)

:) yeah. being the "new" guy, i didn't what to blurt out "man the turbo lag much be enormous with all that piping"; i didn't even want to bring up the topic of lag. as you say, the butt dyno is the only way to get a real answer.

mmm... fancy.

i know it's possible to flip the intake manifold 180 degrees to shorten the piping for a fmic. does anybody know where the alternator relocates to in this situation?

i was wondering about that option also, but wouldn't you have to move the a/c compressor also? seems like a lot of work. i guess it depends how much benefit fmic gives you over tmic.

You would think that the shorter pipes jammed right in the front of the engine bay would give more turbulent flow given the sharp angles and directional changes vs. the smooth up and around design as shown.

But who knows.....

Praxis System Update!!

look at a wrc car. they think the sharp angles are worth it. although they do run with anti-lag and all of the other fancy engine management stuff they get...

i'm no flow-dynamics expert, but i'd imagine that having less to pressurize would offset any problems from turbulant flow, but like you said who knows.

in the end the question is moot for me as i have no intention of going to a fmic, but it is fun to think about.

Here is a pic of a WRX with FMIC anc CF RS type hood.

If that doesn't work, use this and scroll through the pics:

This was at a meet recently held at King of Prussia PA. We had something like 39 rexes there and one STi (mine).
Cheers,

did you see the $110,000 evo in the latest sport compact car? there is a sharp 90degree joint right at the input to the intercooler. i found that surprising cuz i had the same thoughts that you did. dunno...

edit: the 90degree joint isn't to the *intercooler* but to the *intake manifold*. i was describing from memory and got confused with the sti. :oops:
