Curious why the race fuel? Gotta love it when a plan comes together.
Higher oxygen content plus some extra room for timing. Not expecting 10% gain but 3-5% shouldn't be out of the question. Plus it smells good.
Tuner called yesterday, might have covid. Probably wont have it for another month now. This was the last nice weekend of the year. Got the car put away 2 weeks ago so all I can do now is drink beer outside lol.
First pull, no tuning, 65 degree room temp, 100% humidity (rainy day), made 140hp at 5500 with tq showing no signs of falling off. He said it should be into the 150s no problem on pump gas.
Just heard from him again. 152hp, 140tq. at 5700rpm. Just added a little more fuel up top. Timing still needs adjusted, will knock on the door of 160hp STD

Sounds strong-👍
When you get a chance, have him email you the Dyno sheet, and post here so we can see when and where the power comes on....

Thanks!
Will do, we will also check CCP after the full pull Saturday when the humidity isn't crazy high.
We're at 110 ft lbs at 2500rpm, still a bit more to go maybe 5 or so. My 107 was about there and it was plenty for my Dyna with the 30T compensator sprocket.
Heres the last pic he sent me. These #s are at 5700, STD. Peak tq at 5000rpm, math shows at 5700 we are still 140 tq.
LOL I hope I don't! I think I will be too scared to really lay into it for a little while.
Im not far from you (Stephenson County IL) so as you know the weather probably won't cooperate enough for a test ride. Might throw on some snowmobile gear though...

Cordova is about 1hr 20mins from me so Ill probably go there a few times. Byron Dragway is only 30 mins from me so I will mostly go there for Test & Tune weekends.

nice, keep us posted with track updates. Ive never been to Byron, but have raced all bike events at Cordova.
Get your 60 down and keep the bogging out of your runs and youll definitely have a high 10 second bike.
