Building an motor
Any one have any experience with power gains from the 09-11?
I have a "drag bike" (I know, I'm a redneck) and looking to bump up the power some.
I'm looking at doing head/cams (Web .400/368)
Pistons will be stock bore, ether Wossner 14.1:1 or JE 13.8:1
I will also be doing Carpenter Racing valve springs, and APE head studs.
I will be sending my crank out to Marine Crankshaft to have the "oil mods" done, being that I Rev it to 14,000 on a regular bases.
The head will be getting ported by a close friend of mine.
The bike in its Current form made 164hp with a "cleaned up" head, a Brock's sidewinder pipe, BMC filter, factory pro stacks, Dyno tuned through the ECU on 93 pump gas (10% ethanol). That power was with a swing arm that puts the bike wheelbase at 66" (11"ish over stock), And a Shinko hookup tire.
I'm just looking for any info on what kind of power I should see with the above mentioned items. Also interested if I should add a set of H beam rods to the build this winter, or if i would be safe at that power level with stock rods for this year. I will also be tuning the bike on a good oxygenated fuel such as VP MR-12.
Thanks in advance,
Please excuse my title.... A Motor*
