Apparently the other drivers that cant turn faster lap times vs a stock LS6 engine cant drive, dont know the track or how to control their higher HP level on the track.
If you wanna set up a s/c car road racing set it up to use E85 then you dont need a intercooler and don't have to worry about your intake temps either and can a run all day long and never even come close to overheating the engine.

1- do you like to haul all your E85 to the track, 40-60 gallons ? Most likely will not find it around most tracks.
I go thought 20-22 gallons of 93 octane a day at the track. that is 3.5 to 4 mpg at WOT. If I am out just doing laps and cruzing it is 5 mpg.
2. Never seen a SC car last a full day at any event when driven hard. Over heating. Even the ZR1s overheats and looses power.
Stock LS6 engines are still the best options. and at $3200 for a crate motor. Run them and replace them.
Most high HP guys dont last very long, too many broken parts or mechanical problems. or move into older ASA stock Cars, older GT1 / Trans AM race cars and go racing not just lapping.

Tracks need to start carrying E85 but unfortunately most people don't think it works for high hp cars.
To each his own, but after almost 40 years of racing its not too hard to figure out whats works and what dont.

The C5Z does not need a supercharger for HPDE. The car in stock form is more than capable of holding it's own. Here's a video from last weekend at Roebling Road with the Florida Citrus PCA. Car is an 01 C5Z and the only performance mod is a SLP Blackwing intake and 03 H-pipe.

I almost feel sorry for all the German made cars you passed. Almost.

One of our regular HPDE buds just replaced his SC LS1 with and LS7 due to the recurring issues with heat management, belts, leaks in the SC etc. He had 650 RWHP with the SC and has spent the better part of two seasons trying to get it sorted, but after one event at VIR he seems much happier with the NA LS7.
Incidentally I believe the guys from ECS have their road race car set up with Heads and Cam and no SC. That tells me all I need to know.
