370ci pt88 .96ar dyno graphs
So my dyno graph shows a clean hit to 904whp and then falls a bit, i'm windering if this is the issues with all you guys running this setup..
This one only shows a pull @17.5psi, the power drop doesn't increase with more boost...

i'm using the AEM true boost, it is such a pain in the *** to set up...
This graph shows a clean boost hit of 18-19psi all the way but with power still dropping off... Wtf?! I don't think it's valve float, i have double patriot golds with really high seat pressure, spark plugs are br7's gapped to .24, a/f ratio is constant 11.5-11.8...
Could it be the ar on the turbine housing is too small for a 370ci engine? Or myabe my speed inc. TU1 cam is too small?!

I have One truck mani and one fabricated manifold (to clear a/c) , 2.5" pipes merge to 3" into turbine, 4" down pipe, 3.5" cutout (only one i could find will be getting a 4" soon) , dumping through the bumper infront of the tire...

Is your power still dropping with the more solid boost reading? What cam do you run?

I would like to think it carries the power band out a little farther but I haven't had it on a dyno again to find out for sure so right now it's just an assumption. My cam is the EPP blower cam. 232/240 .595/.608 115 if I remember correctly. Your exhaust sizes are similar to mine except I have a 4" cutout. Can't imagine that would make the difference in power curves though.
Thanks a bunch all the way from hot ol'Kuwait...

I'll be ordering that soon but it's going to cost me like 250$ in shipping via UPS, so that sucks...
