Depends what you're after. -5's won't blow till 9000 rpm on a 3.0, so if that's what you're after, wrong turbo.
A grunty, lazy 400-440 kw on E85 with a sorted setup without having to spin it to the moon, perfect.
Well each gear, peak boost will be reached at different rpm due to load, will it not?
And farken "full boost". Unless it has some sort of reference to it (eg 25 psi), it's the most meaningless thing ever. Are we talking 5 psi or 55 psi?
Is your mega pump going flat out at all times, Mick? I suppose on the track it would be going nuts anyway, the only time it wouldn't would be in the pits.
Fuel cooler ahoy!
