How much hp gain???????

[Brad003]

Gotcha. I now have:
8lb lower
Sbtb
Cai
Lightning upper
Cat back exhaust
And a 69.4in belt
Mafia maf
Sct tuner
Ported blower and plenum(about to install)

I went to tune and dyno it and it miss fired at 75mph. So got to change plugs out and go again. Should be pushing roughly 440rwhp 550rwtq when ported blower and plenum is installed. What plugs should I run and at what gap?

Do a search over at the Harley owners site. The info that you are looking for should be there.

is Lee doing your tune?


those are fair for flywheel/flexplate numbers as you won't see that much at the rear wheels

I am brad003 just with a new account. And yes lee is the one doing my tune. For a dead #2 cylinder(rings are bad) so I'm going to at least put forged internals in while motors out.
