Well over the weekend I installed some 1 3/4 ARH longtubes with 3'' X-Pipe and today I went back to ProDyno to dial her back in. Very happy with the results I got! :rockon:
Final numbers were:
673rwhp on 93
724rwhp on e85
Pulley setup is a 3.2 upper/4lb lower on 93(19.5lbs-18*timing)
3.0 upper/4lb lower on e85(22lbs-20*timing)
Previous pulley setup was 2.8 upper/stock lower for pump and 2.6 upper/stock lower for corn which provided the same boost numbers as above new numbers.
From the last time I tuned it I picked up 20hp on 93 and 37hp on e85. Just added the ARH headers & X and 4lb lower kit but the boost was the same last time as this time. Same tuner, dyno, timing and about the same temperature within a few degrees. Soooo to answer the age old questions...YES! Headers do make a decent difference on these cars at higher levels. :thumbsup:
I went in hoping for about 710-715 and couldn't be happier. :coolman:
Video coming soon....epper:
