    Racer X fmic vs Process West tmic?

    I've read a lot about the PW tmic but can't find much useful info on the racer x fmic. There is very limited info out there regarding the racer x. I've already purchase tons of aftermarket parts over the holidays and am just waiting to install. I want to do a full stg 2 build, or I guess full bolt on build with the stock turbo. I'm curious as to how well the racer x performs on the stock turbo vs PW. I'd also like to know how the quality is or any other general info about it you may have.

    If you are staying stock turbo the pw tmic would be a great upgrade. They are some of the best (ets is great as well). You don't need a fmic at stage 2.

    The racer x has a better price tag, just curious if its worth getting over the PW. I under stand its not needed, but if it performs better I'd like to know. Any one have any useful info on the racer x?

    From what I've seen, Racer X is a knock off brand, and it looks to have pretty poor core density. Though I have never personally had one in my hands, so I can't say for sure.


    I would expect the PW TMIC to outperform the Racer X FMIC in all areas, other than propensity to heat soak.

    Okay thanks. I'm assuming not many have used the racer x.

    If you aren't doing a rotated set-up there isn't much benefit to FMIC over TMIC. IMO at least.

    That and the PW TMIC has been proven in many builds to be an exceptional TMIC. Outside of Speed Racer, I've never heard of RacerX.

    The motto to remember here is "You get what you pay for". Sure that price might be appealing but, there is a reason it is so cheep.

    It will also take longer to build pressure....
    You can't have everything - where would you put it?

    will smaller than normal FMIC pipe diameter help with that? one thing I have read is that Racer x pipe diameter is a lil smaller than most FMICs

    That would end up restricting the flow... FMIC is for larger turbos, otherwise it's counterproductive.

    It's more distance to the turbo. FMIC's aren't useful on a stock setup because the stock turbo is small and needs denser air to be effective. Having an FMIC that far away causes the air to lose density through heat soak, therefore limiting performance. (I could be wrong on this principle but, in general this is correct).

    Bottom line, you don't want an FMIC on a stock turbo.

    Okay gotchu, that makes sense. PW is what ill go with then most likely. so far ive got Invidia DP catted, N1 race dual, AEM intake, goin on this week to start my modding. i also got the cobb EBCS but am waiting to get my fuel pump and injectors before installing that. that way i can get it all tuned at once. any other mods you recomend to go along with this? oh and i also got prosport evo guages, boost, oil pressure, and WAFR.

    Honestly you shouldn't install any of that until you are ready to get tuned. Better safe than sorry.
