This sure is not intuitive, but putting twin turbos behind the rear tires is a really interesting idea:

  I talked to them on the phone, and they said 700 to 800 HP would be easy.  Not sure I'd want 1,000 HP unless I had a closet full of ZFs.

  1,000 HP!!!! YEEEEEEEEEEEEA! JB and others are in progress of building twin turbo engines as well SS so you guys gotta stay in touch with "TURBO-DAVE". You shall never be referred to as Crazy Dave again.....Dave is dead.
Can you share specs yet?

I hear your pain bro' on $$$. This year is gonna kill my budget before I get to the first ORR! 
Keep us in the loop though on the new turbo work. At least unlike some people (Mikey) who swear running over a real road with elevation changes, dips, long straights while cops stand on the side of the road giving you thumbs up is wrong or blame lack of sufficient wheels and tires (Mikey) I am glad to see there are still many others who will go and will return.
GO TURBO DAVE

Dog,
Oh yea, I am Crazy, real Crazy. This winter I am modifying my car and
going for 1000hp. I want 750 at the wheels. Intercoolers with dry ice,
methanol injection, 15 psi boost and pump gas. It can be done. But Silve
State? I would love to do it again, but I need better gears and money.
The big problem is money. I dont have any.
