Default Full Size Sierra 72mm 19psi/35 nitrous [email protected]

Bested my own record over the weekend. Previous best was I made 4 10.7x run and one [email protected], no nitrous 19psi dropping to 17 (72mm maxed out) removed passenger seat, sub, and headlight.

This weekend ran same boost but a .034 nitrous first, .042, then .034 last run. (out of fuel so had to swap to the smaller shot again) Nothing removed, full street trim to include towing package (4400 weight) Last pass eng temps was over 200 so it pulled timing on the big end.

Engine is 4.8l, headstuds/gaskets, valve springs, ls6 cam, e85

Drove 5 hours round trip and made it home! She's a tough rig!
