Bob Carpenter released a 219 hp busa from his shop before xmas. It was a 1430 for a guy in the Carolina's. He took it back home and put it on a dyno that made 221.9 hp. That was with yosh setting at Carpenters shop. I don't know about the run when he went home. His $1800 head is making 8 hp over stock. Coming soon 48 mm and 50 mm injectors for the busa.

Is this bringing the New Year in right or what!
 
Nope, not yet! I will try and dig a little deeper. Let me know if you hear anything on your end. That is awesome if his statements are backed up.
 
If it's thottle bodies, somebodies screwed up!

If I remember right the last time I checked the thottle body it messures 48mm on one side and 41mm on the other.

What good would it do to go to 50mm?

The attention needs to be drawn to the 41mm side. (oops! did I just give out another secret?)
 
Just tring to keep you on your toes Frank.I finnally get to back to work tomorrow.been home with the sick kids for 10 days now. need some kind of enjoyment. I cannot play with my Busa till March. but will start on a customers Wed.Hoping for at least 170 rhp.
 
Pipe.airbox mod.possible pc.minor work to the head.it might take more than that .Most customers don't like it but every step dyno but you know that I'll keep you posted.

p.s. did I make you chuckle?
 
Why neck down from 48mm to 44mm...velocity?? If you bore out one end, do you need to bore out the other end the same amount? What if you bore it out more at the smaller end, would you lose velocity (which would hurt fuel atomization)? Any thoughts about boring out the large end MORE than the smaller end to INCREASE velocity? Might hurt flow #'s but...?
 
Yes they can be bored out and think Lee Shierts has bored them out with limited success.
If I remember they start at 46mm and taper down to 45mm at the throtle plate there is a section that stayes at 45mm then they taper down to 44mm in the area where the injector is.

Thomas, theres going to have to be some work done on the head if anyone is planning to any thottle body boring.

I wonder if Lee Shierts worked with the ecm after done his boring?

Anyone?
 
Heard that this bike with all the HP is actually Paul Gast`s and was sold to someone in SC.....was supposed to be quick...all hearsay of course.....told you I had big ears.....
