EVO 16g and a FMIC?
 
I have the insane desire switch to a FMIC now that summer is here, but I would like some input first.

Background: I visited COBB tuning in Plano last August for an E85 tune. I am running a BNR evo16g, AVO TMIC, 850cc DW's, Cobb DP with the factory midpipe and Magnaflows. The car runs great making 325WHP and 350WTQ. Cobb felt that the 2.5" mid-pipe might be an issue, but the results seemed pretty good and the car spools so quickly that first gear is almost useless. (6 speed)

Fast forward

I have recently pieced together a FMIC kit utilizing TXS plumbing, Racer-X intercooler, custom bumper beam, and an AVO intake. I am considering having a 3" exhaust custom fabricated as well. I chose the Racer-x fmic because of the relatively small size (compared to Perrin, AVO).

I also have less than $300 in the FMIC, TXS piping and the AVO intake, so why not.

Ultimately a built shortblock and a Blouch 1.5xtr are in my plans (two year plan), so the FMIC will be a necessity eventually.

Some of my questions are:

1) What kind of gains could I expect with a fmic/AVO intake and/or a 3" exhaust ?

and

2) will it be worth $300 to have Cobb re-tune my car with the fmic, exhaust and intake or just wait until the "two year plan" is together?

I guess I am looking for thoughts and first hand opinions on E85 and FMIC's, especially those who have had the opportunity to compare both on the same set-up.

1. Not alot, but measureable, see my dyno comparison thread in signature stage 2 vs stage 2.5

2. You need a retune if you change intake and go FMIC.

Dr Sharp, thanks for the stage comparisons

I am assuming that the larger the turbo, the larger the gains from a fmic. Also, I should see a good bump, considering there will be exhaust work done as well.

For the FMIC, I think thats a reasonable conclusion. But exhaust will just give you more sound unless you're going to run a GT30+. So it probably won't give you much now, but will help later once you get the bigger turbo.

^IIRC on a similar setup the exhaust was worth negligable hp but more than 10tq. Thats a lot of money for just 10tq if you don't also want noise and looks.

Oh, I hate noise. My magnaflow/factory resonator sounds great. I just didn't want a restriction pushing more air.

Bear in mind, numbers on a dyno for FMIC may not be precisely correlated to gains on the street. You may get more gains on the street due to airflow. Plus you won't have heatsoak at lights, etc. If you already have it, I'd put it on.

Thanks everyone. I am ultimately hoping for a little more consistent performance with the FMIC. The AVO tmic is great, but in the summer it is very inconsistent in terms of performance.

Ask legend about the catback gains. I'm pretty sure he dyno'd his vf52 w/ both stock and a/m catbacks a few years ago when he was changing setup once a month.

Do you have a link or remember the results?

A few hp and a little bit quicker spool. IIRC.

Traveling to Plano/Cobb tuning on January 11th to re-tune the 16G with the addition of a FMIC, 3" exhaust and AVO untake. I will post results.

just confirming, you made 325WHP and 350WTQ on E85?
