Derek from Bootleg Tuned in Wallingford, CT. He cleaned up motor tune and got it running well. Unfortunately the nitrous runs were giving him issues (his input and the plugs were not correlating) so will need to troubleshoot a few things.

Engine is now 11:1 (down from 12:1) and made 640rwhp on 93 octane. Based on the data it's likely still making ~800HP at the crank. It made over 800rwhp on a really fat nitrous run but couldn't get it to be happy so aborted after 4 more attempts. Didn't want to risk washing the cylinders down and hurting the engine.

Build a race car they said, it would be fun they said.

*life gets in the way update*
3+ years later I realize you need Holley spec O2 sensors vs off the shelf. My car ran pretty good but was always a rich. My newest local tuner confirmed this, fixed, and re-tuned. She's running realllll smooth, nitrous tune next.

Holley's O2 sensors are calibrated differently than the low cost Bosch or NTK sensors purely so Holley can overcharge for their sensors. Bag of dicks.

Despite a good install by a reputable glass/race car guy my Optic Armour rear glass is separating at the top. Looks like it needs to be screwed in. Ughhh always something

First official shakedown pass on freshened up combo (motor pass only). The line lock, transbrake, and air shifter all work! 3 year old slicks on a 40* night not so much.
Then the cops came and drove home.

Same run, different view. Front shocks had 10 clicks in from full loose but still came up pretty quick. Needs tires and more testing. 1.47 60ft is not good for this car

Any more info from the new combo to say it was worth doing? On paper it should be much better.

With a full point of less compression, it's likely making same HP as before. I'd say the bigger intake, TB, and exhaust all helped. But I won't know for sure until I get some Dragy data to back it up.

Had the valvetrain and cam not fcked themselves, I'd still be rocking the original combo. I had no choice to rebuild, and adding nitrous will be more competitive.
