OK ya'll here is what I've got and done. And the G-Tech readings we took. And all mods are cumulative unless otherwise specified.
Bone stock=182rwhp 10.5 1/8th mile
Free LS1 ram air mod, put a piece of 3" PVC in between the stock lid (after I knocked out the vanes), removed the screen at the intake neck.=208rwhp 10.0 1/8th mile
3” Dynomax muffler attached to stock pipe and cheesy cut out = 202rwhp (removed)
3” cat back exhaust with a 3in3out Dynomax “straight through” muffler = 224rwhp
3” off road pipe and O2 sim = 236rwhp 9.9 1/8th mile
54 rwhp is pretty good gains I would say for the work involved. However the exhaust is loud and sounds a bit ricey. Going faster is going to require either N2O or a turbo.
