Right, I've just had a look, and found the paper copy and for arguments sake, I used an 8k rpm redline, but I will recalculate for 6.5k, to produce 750bhp+ at 8k, u need a garrett 'gt4294R - 774495-3' type turbo, coupled with an eaton m62 supercharger, with a 10psi pulley, you could use a modified aircon pump for the clutch to disengage this. There is alot more to it than this, I shall try and dig out the word doc! Kev does have a good point with the space issue tho! Have to admit, I was hoping to be the first at this! good luck anyway mate, it'll be a beast when it's done!
