Anybody have their dyno plots from before and after head porting, with no other mods? Just curious to see how the different head porters stack up against each other. Everybody has their favorite porter, but who has numbers to back it up? I have my before dyno, and after I have the headwork done, I am going to dyno again. I want to see exactly how much torque/hp I will pick up. Flow bench numbers are great, but dyno numbers should really tell the tale. Anybody?

 

I can tell you hands down that Portflow and Allaniz heads are good.

As much as 20 WHP gain in the high RPM's.

More RPM= more gain.

Alaniz was one of the machinists that I that I was seriously considering.

R and D said that he would guarantee me 20 whp in writing, so that is another way I might go. I was just hoping to see some proof of how much actual gains various head porter's work produced. Although I know that many guys are kind of secretive about their dyno plots.

 

id trust jeff at IB, he knows what hes talkin about. although i would lean more towards allaniz because they provide b4 and after flow charts of each and every head they port. that in itself is important.

 

Jeff is a good guy. He dialed in my Hondata for me a few months ago when I was running an LS/VTEC. I also got an 84mm VTEC head gasket and some +0.25mm CTR pistons from him. So I definately respect his opinion.
