thanks, there is a video here of me beating a newer Mach 1 Mustang that was running 12.1 @ 110 at Speedworld the night I raced him, soonafter this video I cracked a ringland on my stock pistons after turning up the boost to 24 psi on my old T60-1, nearly every ringland was cracked but no damage occured to the block or head.
I'm looking forward to making some nice power with this setup.

74mm turbo and you are running on 440cc injectors? Better get those upgraded.
Also, a quick word of advice. You cannot run any larger than 720cc injectors with the MAP-ECU on the NA ecu, because you can't control the injectors at idle. 720's are probably even pushing the limit.

The max you can run with a pig back is 550cc. Unless you know how to play with valve jet. With this kind of hp it would be wise to have a stand alone in place. Methanol can't control all the timing you need. It's a quick band aid solution. You would need to find a way to disconntect that OCV so your timing won't reach sky high when reaching high boost.

A 320 system can do about 640cc, a 440cc system can do 880cc and a 550 can do 1100cc and so on.
can't remmeber what stock N/A injectors are, but rule of thumb is about 100% larger injector is the max.

Thanks.. From what I have read 525cc's is really all the stock computer can handle, I got a good deal on the 440's so I'm staying with those for now, I have a Haltech E8 in my closet and a set of 1000cc injectors however I want to see what I can do on the stock ecu. I have a friend who runs 800RWHP on stock 550c injectors and meth injection on his Supra, right now I have it set up at 12 psi on the 440's and its running great, I'm going to take my time inching up the boost. I got the headlights on Ebay, they're great!
