STS Kit and My H/C LS1 I had the Central Florida STS Dealer, Macedo Motorsports install an STS kit on my Z28. The car has a TR224 112 cam and a set of Macedo's CNC Heads with 64 cc Combustion chambers. My compression is too high and Macedo didn't want to put the Turbo on, but I obsolved him of any warranty issues if the motor pops. He and Tim Sloper had to work the computer pretty hard to get it to work with the heads and cam, but on 5 PSI the car cooked the dyno at 475 hp and 460 TQ, Tim was sure that we could have taken the power above 500 hp, but they wanted to keep the tune conservative and the bottom end togther. I drove the car today, woosh, at 3500 rpm the world turns into as blur like light speed. I was impressed that the car was actually a little quiter than the before and the idle was smoother. I will try to track the car in the next two weeks and see how it differs.
take it to bithlo and see what she can do now I'd like to run ya for fun and take a ride in your car to check that sts kit out.
hey if the motor pops its a good excuse to build it!

He has been running consistent 10.9's and 11 doh's, his car is hooking up really well now , but he is gearing up for the no bull shootout, his car is at norris motorsports right now.
I'll let him comment on what he's getting done.
i need to get my car in the shop too I need some more boost.

They are the 4.8 heads with cut combustion chambers, I put the compression at 10.6-10.7. Toohigh for a good turbo application, but I had the kit and I don't have the turbo motor yet so I decided to go with it anyway. Tim and Larry did a great job, the car idles smoother than before.

Bring that Vipper out for the No Bull on Sun 12/12, you might make a few rounds with it.
Yeah Larry cranked it out pretty quick. Your car hooks hard, if I set the Viper up like you have done I'd probably be looking at low 10s. Can't make the 12th, we have the V-10 Nationals in Bradenton that weekend, racing for points can't miss it. I'll probably go out Wednesday, maybe I'll see you there.

Watch out for in intake temp's.At the end of the track they might be over 250 degree's and will slow the car down on the top end.Throw on a OBX front mount intercooler and really feel some power.Drop's the intake temp ALOT.
(don't know if you are running Myth. or intercooler though)
