Super pass..Wow that back half must feel crazy..you are putting crazy power to the track..great job. How much boost on the top?? Or is that top secret??

Not a whole lot (well, depends on what you compare it to I guess).

The best ET on my bike (6.908) was with 27.5psi. The fastest pass on my bike was with (212mph) about 31 psi. The 221 mph bikes have a bit more than that, but still nothing compared to what the import car guys run.

These are all with stock GEN1 bore and stroke as well...just under 80 cubic inches :bike:
I would of figured a lot more but chassis is so important in prostreet setups. Very well done.Thanks for sharing your information.

Back a few years ago, I would have thought more as well. When I first started messing with turbo busas, probably 2001 or so, we would run alot of boost and never ever broke into the 7's. I've learned alot since then and continue to learn more all the time. It amazes me that we were able to make 2 bikes run 6.76@221mph with stock gen1 bore and stroke at the same event. 211, 212, 221, 221 for best speeds from our 4 bikes. Crazy.

Congratulations  man that's great to hear. Those are some crazy times and serious  mph! I would have figured way more boost than that also and thanks for all the info you post. Most wouldn't and I can understand  it's a lot of work, time, and money involved to get a good setup.
Thank you for all the help on this board you guys definitely  have it figured out, I'm glad to see someone  besides  DME  run crazy numbers.

Six seconds?! That is crazy quick. Congrats. What's the next goal?


Hey I just wanted to know why they dont put fatter tyres on the back wheel....they could get more grip right and a better time?

We have to run DOT tires. There aren't any wide dot tires suitable for drag racing. A 240 width Continental was tried a few years ago, but it didn't work very well.

Can't be a lot with all that stress on them I wouldn't figure, I could be wrong I once was in 1982.

Depends on what you mean by how many. While we do grenade one once in awhile, we pull them at least every other race, sometimes after each race, and freshen the bottom ends.

Wow that seems like a lot I guess all that boost is hard on them. Probably  isn't a bad idea just to keep things fresh so nothing unforseen happens, still can break but I guess that's the nature of the beast. You guys aren't  setting records though by being easy on equipment  lol.

I would have had no idea...You guy's have gotten it down to a science, to be able to be so consistent and maintain that level of performance...Damn good job!!!
