D1 dyno results on 2001 Z28 Almost done with the Car and here is our latest dyno #'s(this is street tune on 93 Octain)
Specs:
2001 Z28 M6, Forged pistons,stock rods/crank,Patriot LQ9 heads 72cc, 230/234 .598 on 114 Cam,LSX 75mm intake,ported TB,Procharger D1 pulleyed for 8lbsHooker headers,Corsa exhaust(no cutout)42lb injectors,340 Walbro intank with -8 feed,rails,boost sensative regulator,run through a Denny nitrous shaft and Moser with 4.11's,315 Nitto's.
boost was at 7lbs at 6200rpm
591hp at 6500
509tq at 5200
A/F was 11-1 to 11.5-1 across the board
above 400hp at 4500rpm,5500rpm was 500hp
The injectors are maxed at 6400rpm,so new 60's are going in.
Timing was at 19 degree's total.
What do you think?

Cant wait to see what more fuel will do. Any thought of

We see no signs of slipping.Also running the 8rib so 8 lbs shouldn't stress it.Next winter the thought of 12lbs is nice.The problem is right now the car is limited on traction in the first 4 gears.So 12lbs would put us around 700 or more.
Pretty impressive numbers. 
I had a similiar set-up minus the better heads and cam (mine was a single pattern slightly smaller and the heads ehere factory stage 2's) and only made 587 rwhp at 12PSI. Who said heads and cam aren't as inportant with FI!

The power is very linier till about 4000rpm then the tires break loose.So when it's done it should be a very tame daily driver.

Great job..... gives me great hope of hitting my goal of 600rwhp. If you dont mind me asking what size is the crank pulley and what size is the blower pulley?? My 8 rib setup should be ready in the next couple of weeks an i am wanting to see 14-16 psi on my forged 370. you went with stock rods?? What rod bolts?? Thanks

don't think you'll need the 4.11's though.
Can I see the dyno graph?

The Cam is big but very tame for everyday driving.We went bigger Cam,lower boost for the power.Hopefully the owner will scan the graph and post it.The car also make 420hp/390tq before the blower was put on. 
I will get a dyno graph up soon for you guys...the kicker of this setup was the low compression setup still netted 420 untuned before blower. We were expecting 380-390 so its been all gravy since then
now I can't wait to get Mark's car (BlwnTA) on the rollers

ya its an m6, dont expect too much track time, Im running on nittos and takin it easy. Im not a big track guy and dont need to hurt the car. I will run it this friday for fun though. I have serious coin into this car.
