I have an 07 street bob, my build is almost done Heads come in saturday,
Im going to a 103" SE Forged pistons 10.5:1 compression, Tw9 Wood cams (650 lift), Heads worked over by interstate junction.

What should i expect for HP/TQ?? anyone have a similar build?

 

BTW V&H big radius pipes and power commander

 

I've got the 9BGs at .630 with 9.5:1 pistons. Getting 109 pound feet and 107 HP. I'm betting you'll be +10-15 versus that...Let us know.

 

Kinda getting off the sunject. Interstate Junction?? Where is that, don't mind me asking?

 

yea ill def. let you know ill post the dyno sheet, Interstate junction racing its in albert lea MN, Bob woods told me about the place so i ended up sending my heads there, they have taken almost SIX WEEKS!!!!! So they better be some ****ing good heads

 

I'm thinkin between 110 & 115 hp & tq, not sure what they're doin to the heads? Pipes will hurt a little compared to a 2 into 1, but your headed in the right dirrection! What are ya doin with the throttle body? What clutch set up are ya gonna run? Good luck man!

 

WOW thats my hometown. Small world. All my buddies take there stuff there. Grew up listening to him race his bikes down S. Broadway on test runs. Just shocked to see his business here, didn't know it was that well knowen. Good guy, does great work, never hear a lick about something bad.

 

im going to run a 50mm SE throttle body , as far as the clutch goes stock besides Heavy duty clutch spring.

 

Right on...fu**er will rip (nice parts)! Only thing I would look at changing is the clutch set up. I'm only sayin this cause I'm tryin to save ya the time, my stock clutch with HD spring slipped with 108tq. Nice set up though!

 

All the above info does not matter. HP/TQ is always 2 * PI * RPM / 60000

(I know that is not what you were asking but I couldn't resist, old engineer.)
