Still working a plan for replacing the LS3 that let go last month. Have quote for machine work and long block to make 550+ RWHP but remaining NA. I am still heavily on that path but honestly its not cheap to build big streetable power and stay NA. Before someone throws it out there, I'm the first to admit you have to pay to play. Curiosity is killing me though.

I am just curious who is running HPDE boosted, what setup, and how it handles the extended high loads and heat. If you are boosted or have some experience, please share. Thanks.

SLP2300, 6.5 lbs boost. About 470 rwhp - plenty for fast takeoffs and good acceleration anywhere in the torque band.

I have heard from the ZL1 guys that heat is a problem, so I have done a lot to keep things cool. Hex vents in the hood, a splitter to drive more air into the grille, opened up the mail slot, and plumbed in a remote oil cooler down low up front. My coolant temps rarely get above 205 even after a full 25 minute run at VIR in high 90 degree heat at the end of June. Before the oil cooler my oil temp gauge went into the red but honestly I am going solo these days and keep forgetting to look down at the oil gauge to see where the temps are. But if coolant stays just over 200, oil can't be a problem...

SSSoon,

Any problems with detonation and knock retard?

Anyone else running with boost?

No problems at all. Jannetty Tune, refined on a local dyno, emailing results to Ted in real time and getting updates.

Went with the n/a set up like you are talking about. I have done a lot off autocross in the summer with no problems. Not a road course but the one in bowling green is not finished yet

Curious how much it costs to do this properly (NA, 500 rwhp). Any ballparks?
