hey guys,

I'm ditching my greddy setup for a more powerful one (Precision baby!). The only thing im keeping is the type 31 IC and all the piping. After the turbo its 2", then after the intercooler its 2.25". Now Im planning to run 325 whp with my new bottom end build up. So im wondering if these pipes are satisfactory for that power level or what, will it make a BIG deal? Or should I get new 2.5" piping all around?

Any comments welcome.

stay with 2.25, smaller piping = steady pressure, velocity and those will make up for the volume.

Boost is a measure of pressure, Pounds per square Inch

2.25" max like Stan says. Can be used to at least 500whp

 

it's too small, just give it to me

lol nahh Alan ..

Thanks Earl and Stan, that's what i thought too, I just wanted to run it by everyone

 

are u guys messuring the inner diameter or outter??

 

I run a crazy 2" to 2.25" to 2.5" setup. Someone did the choke flow analysis a while back and found that I think it was 2" piping will support over 750 hp. It may have been 2.25" that would support that, but the point is unless you have a y2k on a supra you'll be fine with anything in the 2-2.5" range.
