C3 SC pulley??! If you are, PM me. Thanks!

 

It sounds like you are ready to go C3 pulley along with your 178. Good luck and hope all works out great for you!

 

Indeed I am! Thanks! I wan't to do some testing with it.

 

I believe that there may be more than a few of us. I like the higher boost aspects with less revs on the pulleys. I want to get it working with bigger manifolds and then try a boost modification - sort of a limiter this spring.

Woody, Be happy

 

Are you planning on an injector upgrade?
I do know that even with an accurate tune you stand a good chance of leaning out at 23lbs or higher.
Good luck,
Mike

 

If it is needed, absolutely! I am going to do some testing with it as other people have tried. I am not giving up on the idea yet. Although my thinking is at this point, with the larger intake Mani's, my boost wouldn't be hitting max. On a stock setup, this may be the case, but I did notice a drop in boost when I installed the NW mani's....Then again, I could be totally wrong. :P

 

I would like to humbly add that the boost would not drop with the better manifolds, but infact increase.

THis too sounds bass ackwards, so allow me to explain using an ASSUMPTION. I wonder if you might be sensing the boost at the wye pipe? Many are.

If that is correct, the larger manifolds with their LARGER inlet pipes flow better. This reduces the wye pipe pressure due to the BACKUP of the air flow into the manifolds. Sort of a standing wave or turbulance bump.

Conversly if you were sensing at the manifolds you should see a higher pressure ( peak) due to better delivery from the wye to the manifold(s).

Later this year I hope to take receipt of a bigger manifold set. After I get the manufacturer the info for his benefit, Ill show you how I will increase their rated flow by approximately 40%. Pressure gradients are very much related to time (the passage of time).

Woody Be Happy Coloring out of the box.

 

Yes Woody, I am reading it at the Y inlet and not the actual mani's. Interesting.......

 

I am reading at the NW mani's, and I'm from 15-18psi on a full run.
