Sts dyno numbers
Sts dyno numbers Here is my dyno run on 5.5 lb and everything that is in my sig. The lower pull is my h/c package pull on the same dyno before I installed the turbo. I have a NA cam right now so my numbers could have been a good bit better. You can view my dyno sheet at http://my.starstream.net/f8lpony/Pho....5psi%20sm.bmp

NP man, glad I could help... It would be fun to take a ride in that beast when it's finished. My cars have been decently fast so no matter how fast i make the truck it still doesn't feel fast. My satisfaction comes from seeing the looks on peoples faces when I beat them rather than actual adreneline pump you get when trapping 120mph+
It seesm like the cam is bleeding off boost on the bottom end so it's hacing a hard time getting power up. Wait till you get that new cam and some lower compression. It's gonn abe wicked!

Nice numbers, but why did u stop the run around 6K RPM? Take that sucker up to 6500RPM. 
Also i dont think a cam change would affect your setup that much because the turbo is really far from the manifold hence less effects in spool up and EGT when changing the cam specs. I would go with a big cam 230/230 or 232/232 but 115 LSA to keep the boost in the combustion chamber. Just my .02 cent.

I took my 230/234 591/589 114 cam out on saturday to go with a 226 turbo cam on 115. Idles at 700, its quite and I can peak the car at 5800 which should be 600+ at the wheels. Less revving equals longer engine life. Also much more streetable.

With only 14 degrees timing to start as well. At 9 psi and the old SC cam it absolutely screwed once it made boost but it came on too late for me. So the new cam is in, gm mls gaskets are in. All buttoned up with a big fmic as well. It will be tuned this week and I will post all the numbers. Im starting at 10 psi and going from there. Hoping to make 550-600 rwhp and 650+ tq. We will see. Im willing to push the gt70 to 15psi. Wish me luck 
Also used to run the d1 with 24 degrees of timing and always had 0 knock but the iat's were 140+ after one run. After about 5 wot street runs with gt70 and fmic they were 78 degrees. Im gonna push the timing into the 20's as well.On the dyno when it it blew it only had about 4psi but still put down over 500 rwhp and 490ish tq. So tripling the boost and upping the timing from 14 to 20+ outta be good

PurEvl, did you happen to take note of the RPM range when you started developing power with the new STS kit? Also, when did you develope power with the D1, in comparison.
I appreciate the info, both for my own good, and for those hashing me for considering STS...
