at 4.5-5 psi the truck made 444 rwhp and 476 rwhp SAE. I haven't had a good trip to the track and only been out once with the new setup. Its just been way too damn hot and humid to get a good run here.. We are in the 90's now during the day with pretty high humidity. Even still it went a 7.901 @ 88.6 mph I'm really expecting it to touch on the 7.7's when fall rolls around.
Do you think the T60 is a little small or just the right size? Does the power drop off pretty early? If the 67 were in its place do you think it would change a whole lot? More power up top with a very small increase in lag?
I feel like the T60 will carry me conforably to 10psi which is the limit I want to go with the stock compression. I may lower the compression with a set of l92 heads and take it further. I have a T67 I can put on but to be quite honest I'm very happy with the 60 on the truck now. it pulls right to redline and the IAT's stay cool
