Hear what our customer has to say about his 170 rear wheel horsepower S&S 145" engine:

"I got out on the bike Sat. afternoon.

WOW ! What a beast! Acceleration

was effortless. I was cruising down the

road at 85 mph before I realized it.

What an incredible feeling. The best

part is knowing that it's nowhere near

its full potential. My need for speed

has been fulfilled. Thanks for all your help

and patience. You and everyone at

Star Racing did an excellent, excellent job.

Thanks again, Mike."
