Just finished making dyno pulls on the car today. To be honest the day was a little disappointing but overall there appears to be some left on the table if we can add more timing. Running 91oct and 100% Meth Injection and boost at 25psi the most timing we can have is 8*. Any more than this the knock detector was showing KR and would pull timing. We added 2* and made 30hp but there was knock so we dropped the timing back down.
So here are the Key Factors:
Dyno: Mustang Dyno
Timing: 8* Total
Fuel: 91oct and 100% Meth:
Transmission: 4R70 with converter lockup.
Exhaust: 2.5" full length
Before the end of the year we're going to use race fuel and meth then see how much HP we can get with just more timing. With just more timing we think we can get over 800hp @25psi then we can start cranking the boost up and see where the HP goes. So the 735 is a bit depressing even tho that's through the 4r70 but if we can get over 800hp with just more timing then adding boost should make some solid numbers.
