This is my 2003 Lightning. It made 413 rwhp and 528 rwtq on 100 octane fuel and the stock Eaton blower. I then installed an alcohol injection kit on it which allows me to run race timing on 91 octane pump gas. I later added a ported Eaton blower from Apten Performance. On pump gas it made 428 rwhp and over 500 rwtq.

Next set of mods were a KB blower, 4# lower pulley, cold air kit, and SCT Racer Pro tuning software. In 100 degree heat it made 457 rwhp and 549 rwtq.

At 500 rwhp or so the stock fuel system is no longer up to the task. I nosed it over at WOT and broke a rod. So a new billet engine is going together from Dante at Modular Performance. Crower billet rods, Crower crank, coated pistons, Stage II Crower cams, fully ported heads, etc. Shooting for 560rwhp+ on 91 octane.

New chassis dyno numbers are 544 rwhp at 16 psi with the 91 octane tune and 100% stock exhaust. Jumped to 578 rwhp with 20 psi but the stock exhaust is really holding it back now. Problem is the headers and high-flow cats are sooooo loud!

With a full Dynatech exhaust with Bassani cat-back, 21 psi made 621.5 rwhp and 708.7 rwtq.
