Talking TurboXS intake

I just installed the TurboXS intake on my Rex, and I have to say its leaving me with a very good overall impression. From looking at the other CAIs on the market I decided on the TurboXS unit for one reason. K.I.S.S. or, to the uniformed Keep It Simple Stupid.

It consists of a simple aluminum bracket, machined aluminum section for the MAF sensor, a cone shaped K&N airfilter, and a couple of hose clamps. Installs in the same area as the factory airbox, not the fender (I feel the air in the fender is potentially too turbulent to be a big benefit from cooler temperatures). Incidentally I initially installed the MAF sensor backwards, makes for an interesting attempt at starting the car when the computer thinks the engine is having air SUCKED out of it - pay attention and dont make yourself feel stupid like I did.

Now for the good part... The turbo spools up noticeably quicker, starting at probably 4-500 rpms lower than stock. According to my (not terribly accurate) stock boost gauge, I am making about .01+ MPA (not sure how that works out in PSI) more at max boost in third gear. Nice side benefit of the location is that you become intimately involved with what the turbo is doing, the intake sound is very attractive, almost sounds like I switched out the exhaust.

I would reccomend this to anyone.

This is the first mod I have made to my Rex, more to follow.

I have this intake as well. I have nothing but good things to say about it. First off what everyone wants to hear NO CEL. Thats right, it has the exact diameter of the stock MAF housing so no CEL lights will be on.

Second. The sound is amazing. Nice loud spool up of the turbo and a large gulp of air rushing is as you stip on the gas.
( I list sound first because of the nominal and almost none existent peformance gains with the stock turbo)

Third. Performance gains. I can notice the turbo Spooling up a bit sooner than stock. Over all turbo spool up speed somes a bit quicker, but it could be my imagination. I have no acutal numbers to back up this theory.

In any case, this is a good product that will not harm nor really majorly help your car, but d*mnit it has a great sound.

Default TXS shorty intake

Recently I added the shorty intake on my stage 4 car. Immediately noticed that the car was far more responsive. The other benefit is the sound. Yes it was very nice to have the bypass valve be audiable. Very pleased with the kit and the hardware that it came with. Well worth the price that they are asking. And no CELS from it.

Default One question

Will installing this intake change my A/F ratios? Reason I ask is because I have a nicely tuned UTEC map and I dont want to have to mess with it.
