Stock Heads and Cam , besides you do not need to turn the motor 7k . The only reason you turn a motor 7k up is for air flow which equals hp. N/A and S/C cars require this to make power. The more RPM the more boost on a S/C car . Turbo cars do not need rpm's to make power . There is no need to dyno at 7k , besides if you notice the hp starts to drop . This is because of air flow not b/c a Hellion Kit is restrictive as someone else had mentioned.
I have stock heads and stock cams I do not turn the motor past 6100 to 6200. The power starts to drop because of air flow .
I made 836 rwhp/ 848 rwtq at 22.6 psi's , Im now able to turn it up as high as 26.6 so if I had to guess I would say its gotta be close to 900 rwhp and 9xx ftlbs. Still no higher then 6100.
BBR's numbers are on Pump 93 gas , put c16 in it and 19* to 21* of timing and the car will make 700hp easy.
Thats also a 67mm Billet Wheel , go with a 74mmbb or 76mm and it will pick up another 50hp across the entire band at the same boost .
Hey John what back a/r is that a .81 or .96. I would think the .96 would work well on the 5.0s with these 4v heads should pick up a ton in the back half.
