Found broken valvespring, 13 psi PT88 820HP corrected vids added Finally figured the car out. pulled heads to do lifters thinking we had a lifter problem and found a broken outer spring. Hit the rollers again 13 psi PT88, PT A2A 91 octane, 408 CI HP tuners, victor JR, etc... Remember this is corrected at altitude. The uncorrected was 675HP ish. Ran 10.1@138 1/4, 1.54 60, 6.57@109 1/8t mile Density altitude today was 8322Ft. Car still needs some suspension tuning and a big diet.

Be good to see you out again. I have another TA we are finishing up with our kit. Small turbo -s70 stock cube but forged with nitrous. That car is 100% full weight a/c, p/s etc.... I am interested in seeing how that car does on our kit.

24.6 Baro is nasty bad. I thought our 27.2's was bad here, but you're the king of bad air. BTW, ATCO and Englishtown will hit 30.50 in good weather for a comparison. Your car is making great power.

We do the happy DA dance to the DA gods if we see 6k ish DA. lol. Some of the bike guys were down from 144- to 138- ish on their traps that day too. Seems only people that really know what high altitude does to performance have to live in it lol. I see a trip to vegas and some changes for PSCA next year for the car. Limited street is looking fun.

Thanks guys. I am just a small shop Doing what I love wishing I was a big shop and playing with the ls1 guys. They are much more fun than the mustang guys. Hopefully we can become a vendor on ls1 tech very soon and help other people out. More videos to come in the next few weeks as we get the next few ls1/2's on video and a weight of the white pig.

I wish you and your guys all the best of luck this year. I've learned a lot from Sean and Eric and can't wait till these guys become a vender/sponser on here. They have a strong work ethic and very good integrity. SOLID!
