I have always heard sb pipes make more HP on a dyno but BB pipes will run better times on a track. BB pipes have better "useable" power from what I have heard from a couple guys that own dyno's.

That's exactly what I'm noticing from my switch to BB pipes over the SB. Less over-rev, broader powerband, more useable power...It did "seem" that the SB pipes pulled a bit harder, but the powerband was much more narrow...Just my opinion

I will be able to tell you guys just that after this weekend coming up.
My pipes (big bore) are in for repair...

I'm bringing a set of Shearer big and small bore to the races, for my 10 mil cub.

4 different (well respected) folks ALL said small bore on a 10 mil cub.

His current Big Bore pipe was designed for a 535cc Cheetah...

I've got 10 hours of test and tune on Friday, 10 to 8. Going to try both sets of pipes, gearing, etc...
I'll let you know when I get back from racing.
