Going for broke

We were able to get my car tuned today. I verified a couple of things today which in the back of my mind, I already knew. My turbo was close to being maxed out before, now it definately is. The other thing; water methanol injection really is the shit. This tune was done on 117octane without water methanol injection, and timing ended up identical to 93 octane tune with water methanol injection.

I feel more comfortable on race gas running high boost however, because years ago I found out on our tC time attack car that above 30psi cylinders 1 and 4 don't recieve enough water methanol as it is distributed through the stock intake manifold. We were able to tune around that because the Haltec sport 1000 had individual cylinder fuel and timing control. My Haltec sprint 500 however, does not have that capability.

My T3 60trim (.42ar compressor, .48ar turbine housing) maxed out at 31psi of boost peak, held 28 at redline. I am not dissapointed however , because we squezzed out 20whp compared to my previous 27psi tune. This should definately get me into the 11's on Monday .
