Stock Bottom End LS7 and 10 PSI? Has Anyone done it?
I'm making 600whp on a 3.8 pulley with the A&A V-3 T-Trim Blower (7 PSI, very conservative timing), just ordered a 3.4 pulley, and am curious to see how it will live @10-11 PSI.
I run 110/91 (50/50) octane mix, and will plan on a 11.2-11.5 A/F.
Have the Rev Limiter set to 6500, may even back it down a little....
Engine has never had the valve covers off....so to speak.
Curious on your thoughts....

Meth needed in addition to the 110?
I have no issue running straight race gas, this is just a weekend toy.
Not a huge fan of meth, as that's just one more thing to go wrong.

Ask Rodney at RPM transmission he is at 15psi. On a completly stock engine never had the valve covers off. Making 689 rwhp thru an auto swapped Z06.
Here is a nice little read on his car.

First off, let's discuss the engine combination. "The car has a completely stock [LS7] engine, never even had the valve covers off!" OK, well that was easy. Moving forward in the engine bay, we have the real secret to the horsepower, a Procharger D-1SC supercharger system that has been tweaked to work flawlessly run after run. For maximum boost, RPM installed a Cartek flip drive and 8-rib Innovators West crank damper, which brings boost in at 15 psi, enough air to lay down over 689-rear-wheel horsepower. Helping expel all of that air, Rodney relies on a set of Kooks 2-inch long-tube headers, which feed a 3-inch X-pipe and a set of B&B bullet mufflers. And, that's it for power
