I did a search....didnt find anyting related to HP capability...

Thanks for any info

 

Anyone?

 

I read somewhere that for up to 400 hp they recommended 2-2.25 inch piping. Not sure how accurate that is though.

 

300 I was told was the limit 2 inch will flow, by a very well respected tuner/driver (10 sec integra owner.)

 

I would probably listen to that guy, and it sounds reasonable.

Although, I think Drag and Revhard both use 2" and a portion of 2.25" piping, and I know Greddy uses 50mm and 60mm piping which is 2 and 2.25 and there are some guys using those kits are doing over 300.


I need to figure this out before I re-do my piping in aluminum. Changing stuff around with steel is no biggie but the Al is gonna run about $200 in materials alone.

 

I'm shooting for the fastest spool up possible, but making sure not to cut off my goals in the process

go with 2.25, good flow at lower boost and support a higher app as well...I have 2.25" all around

remember, boost is a measure of pressure, not volume...they're both plays critical role, so use your judgement....think about the amount of flow your turbo support as well...

I am using 2.5" piping on a d-series motor pushing 12 psi, does that sound like overkill to you?? What affect does bigger piping have on power and spool up time?

 

I thought most greddy piping was 2.5? Yes it is overkill yeah I would reccomend 2 .25 if looking for over 300 hp, Mplex if I was you I'd go 2 inch
