intake plumbing

going with the MAFt but still going to recirculate bov instead of blowthrough because im not a fag like paul walker and want my turbo to spool up a little bit quicker. anyway heres my question. im gonna have the MAFt and i want to have my intake plumbing go down instead of up so that my intake cone is where the stock 97-99 air dam is on the passanger side. i need to find a good FMIC that flows good but has an upic that isnt in the way of that air dam. hopefully this intake route will get some fresh air and will be a little different aslo too. also i need to recirculate the air so my bov needs to be somewhat close to the turbo. i figure if it blows taht extra air close to the turbo(5 inches or so) it will maby spool up quicker. i will fabricate all the plumbing so dont worry about that i just need to find a FMIC thats "output" pipeing isnt in the way of the donwward intake plumbing. any suggestions?

Well, the MAFt isn't going to be the most cost effective way to spool faster... I would venture to say that it won't help spool or power that much at all, unless you were out-flowing the stock MAS. Also, the BOV is closed during acceleration, so it's not going to blow any air into the intake/turbo to help spool.

If you still wanted to do it, a lot of FMIC's have 'short route piping' that doesn't go through the stock SMIC location (where you want your filter to be). The stock SMIC location, in the front air dam is a pretty common alternative to stock location for an intake. This is a picture of Andre Cardadeiro's CAI.

Here are a few pictures of his custom short route piping (on a Spearco 2-216 core FYI) and his custom cold air intake filter location.

Have fun.

yea but this race shop where i live says its better to reciurculate than blowoff because it reduces turbo lag. i know that the turbo doesnt suck in air when not under acceleration and that is when the bov releases the air but still if that extra air was in the intake pluming wouldnt that make it easier for the turbo to work rather than having to suck it all through the filter etc. and i also read that the MAFT flows ALOT better than the stock MAS. like 800% better or something.

thanks for the help joe

Running the MAFt will help with spool wether you run it in draw through or blow through. But the effect of recirculating the BOV will be just a sliver compared to the gain you get from the MAFt. In fact I think you will be hard pressed to even notice it or be able to measure it. But there is no reason not to do it... If you set up the MAF in draw through, you dont even have to mess with your current intake/BOV setup, unless it is for other reasons.

I dont like to put the filter that low on the car, but I also run a 4" duct down to the bumper opening from my air "box." Let me also state that cold air intake has a very minor effect on power output on a turbo car with a FMIC. I have a novel sized explantation for this somewhere, but the short version is the FMIC will cut down any drop in intake temps by 80%. So if you cut your intake temps by 20 degrees, its really ony a 4 degree drop. Etc. But it doesnt hurt... :)

What size turbo is this setup for? Smaller turbos like 16G see a small gain in spool up since they already spool so damn fast. On my 56 trim I picked up a couple hundred rpm in boost threshold (rpm for full boost) but massive improvements in lag (time to respool after a shift)...

my 97 gsx is completly stock i just bought it like 2 days ago and now am selling my 97 gst. im not sure which turbo im gonna go with probly the 20g. my new gsx only has 100k and when it goes out i plan on swappin the 6 bolt in and building a nice enginge. until then i want to do mods that can be transfered over to the 6 bolt. i thought a good start woudl be BOV, MAFt intake and FMIC plumbing along with a FMIC of course. my goal is mid or high 12's with my new enigne because i want some reliablility but its not my dd. from what your saying gsxracer... and i kno you know your shit.... the cold air intake in that air dam really wont make a difference since it then travels throught the turbo to become very hot anyway then goes through the intercooler to cool off. so cold air intake is basically usless on a turbocharged car. so its makes more sense just to put the air filter in the stock location right. its easier and plus it will create more room for the intercooler piping with less bends and the intercooler is a lot more effective becuase it cools the air after the turbo fries it right?

It doesn't take away or give any more room to the FMIC piping, or make it have any less bends. With either intake setup, the FMIC piping is the same. Other than that, you are right and good luck with the plan.

i just thought the air filter not being down there would give you more room to play with. i didnt even think of setting up the air filter like Andre C. instead i thought instead of curving the intake up to wehre it sits stock. you could curve it down but the radiator hose is in the way and a FMIC pipe would probably be in teh way also. thanks for the help guys
