What If Build Ideas...for Land Speed Racing

No budget? R5P7 with a giant turbo on meth.

Realistically? A bulletproofed 400 BB with a giant turbo on E85-90.
I knew someone would go there on the lack of budget. Just an average guy. What do people think is needed to run WOT for 5 miles at a time and make the HP number?

You say giant turbo, but i would think something capable of 20-25lbs of boost should be enough, no?
