Waiting for some dyno #s from either of these two mods. Would really like to know what kind of potential is in them, more from a curiosity standpoint actually... since I dont have any $ to do them...

 

hihi long time no see...how is the VI going?

anyway Mr Eous has dyno from stone racing header, and i believe i30tmike (i30/i35 moderator) just recently installed PF TB and getting a dyno done. pm both people.

btw daniel says he miss u

 

Stone Racing Headers Info...
Cattman Headers Info...

Both links above show gains from both headers currently available for the VQ30.

My opinion, do not get headers unless you are just looking for every single possible hp available.

 

Those are nice dyno's but what I want to see is a dyno comparisson of the an aftermarket y and the header replacement back to back from the same vehicle with same mods and same mileage under the same weather conditions on the same dyno.
To me thats the only way to prove how much of a gain over the aftermarket y the headers have.
I keep seeing to many assumptions of 10+ hp over the aftermarket y but no numbers.

 

That's what everybody wants.

I would have done that comparison if I had the money and an aftermarket ypipe. The only controlled factor I had was using the same dyno for before/after.

 

For what it's worth, my SAFC registers a consistent 4% increase in maximum MAF voltage after installing the Pathfinder TB, boosting at about 11 psi.
