I saw good results from swapping up to 3" piping and a 70mm TB from 2.5" piping and a 65mm TB. We had made 711whp 35psi BUT couldn't get any richer than 10.8:1 on the dyno, we called Tony1 and he said to try the 3" piping and 70mm TB we had and voila car made 714whp with only 32psi after that change I believe Tony mentioned he felt anything above 350-400whp will benefit from the 3" piping. Again it was his opinion he stated and not a tested fact, he has given me his gut feelings before and they always seem to work. Tony1 for all teh help over the years man!

 

Thanks alot.

 

Tony1 for senator yo

 

 

hmmm...i would have not thought that 3" pipe would make that much of a difference... and 3" will not allow boost to build as quick if your running lower boost settings...

I always heard that too, same with trying to make the intercooler piping as short as possible.

I don't believe it anymore after moving the intercooler in a friends car from behind the bumper to in the back seat, along with 4" piping instead of 3" piping and seeing zero change in spool.

Harder to fill a bigger amount of space with smaller turbos from a 2.5 in to a 3in piping...thats just what I hear. Could just be hearsay or bullshit.
