I'm not at the limit just yet. I'm only pushing 10 psi and the engine was built for 15. I need to change my IC and the exhaust housing on the turbo's. I believe I can get 800+ from this setup. It may require a larger center exhaust pipe but that's yet to be determined.

After working with my rear mount I would say it's simpler just because of the room requirements. It's much easier to get to everything on the rear mount. The oil return system is a little more complex but it's been a proven design on both my LT5 and LT1 rear mount cars.

Yes, Corey has expressed a desire to go for 1000+ rwhp. He just needs someone with the desire and deeper pockets than required for the rear mount.

Yes I understand... I know you've been dreaming about this and have lot's of traditional idea's. I'm just fortunate enough to have been able to pursue an alternate avenue that I and some others have thought to be a more economical means to more RWHP. Plus the benefits of removing heat from under the hood and moving weight to the rear of our cars is of some real benefit.

very exciting stuff.

E85 is an option with the new ECM. Mod the Fuel System and you're in there.
I've been kicking around sending the test Ruby to Corey after Megasquirt is finished. The idea would be to install the Raptor LT1 Single Turbo system on the LT5 car, add Meth for a safety margin and then turn up the boost to 6-8 psi. I believe we could see 550 rwhp from the stock block. I'm not just pulling these numbers out of thin air... There's another single turbo car out there that achieved those numbers however it didn't last long before needing a new head gasket. I believe the new ECM and Meth protection should keep her safe... I may install Jerry's head gaskets as an added safety measure but that's more $ of course... This would be a sub $10k upgrade.
On another note. Last update from the Megasquirt guys said they were on the dyno this week. Last report before that said they had a little more integration work to do with the A/C but that was it. I assume... that means all the other sub-systems are working as they should. I'll know more this Friday...
Cheers,
