Thanks. Your large single isn't a TA45 type is it? This should give around 600rwhp! I looked in to this but cost (and lag!) is pretty great! From information I could get the turbo would spool at around 3500-4000 rpm and should be able to get the V8 to spitt out 800rwhp, I reckon 600 would be possible though... It is tempting to do it, but then you run into waste gates $700.00+, turbo $2000.00, not to mention a killer clutch setup! Smoking the tyres at 150kph would be a sight though hey
