Re: Mac vs Hooker LT dyno..

I have seen at least 25 cars gain about 22-25RWHP from MACs with ORY...

Only one person responded to my post. They got 23 hp from running a long tube header. That means that the mac headers are only good for 13 hp. That's not very much for such a big investment. I was hoping to get 30 + hp and torque from a header swap. Then I heard that 2000 and newer cars have better ezhaust manifolds and that the gains are even less. Has any seen serious gains from running headers.

Maybe they didnt tune or something because that sounds like bs.. I went from 344/357 to 368/378 with macs. So umm macs are definetly good for power.

Re: Mac vs Hooker LT dyno..

Mac's do make good power, I made the numbers in my sig with no real tuning like LS1 edit. I only had this POS maf translator that leaned out my car a little. I know if I advanced the timing with LS1 edit I would of saw over 400rwhp.
I have been thinking about switching to LT's but not sure its worth the gain once my heads go on.
