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.

Interested in your track times, I don't recall ever seeing any posted, but I haven't read through this thread in a long time...

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
