Nice..... I guess Nitrous well help your pre spool, I was having a long chat with dusty about the 76mm.. Sounds like an awesome turbo at the later mid to top end.. Ive gone with a larger hotside than you have as im wanting more top end car... Be interested to compare spool times for sure..
looks like anything after 1.65 to 1.7 bar on uk fuel might need water spray, e85 or race gas to go further....
I might go down the nitrous route myself is spool is too bad... Im hoping for at least 8,200 rev limiter on the wangan so should be a good enough power range.
