The Sae Was 1.01 And No I Dont Have A Cutout But I Figured The Car Would B Breathing Enough Through The Headers No Cats And Slp Loudmouth Which Remember Doesnt Have A Muffler
The air was horrible yesterday. There was no knock. We have him tuned in at 13.0:1. The 9" is definitely eating a lot of power, but it does seem low for a h/c car. We are not the biggest fan of the Patriot cam (Made by Lunati). We prefer the Comp Cams XE-R lobes, they are definitely more aggressive and we use them on all of our Equalizer packages including the dyno record holding 505rwhp combo.

With the Lunati 55006...224/224 .560/.560 112CL and stock lS6 heads I made 370 rwhp and 360ft/torque. I would say the heads and cam are the culprit along with the 9" rear. I hope it works out for you!!!
thanks for all the opinions guys ya theres something defintly not right with this while picture. the car produce much better numbers and i have such a free slowing exhaust im sure its not a cutout even if it was i still wouldnt break 400rwhp and thats really upsetting right now. im going to try and find something i can do but im almost out of ideas witout spending another 3,000 dollars which i really cant afford right now
