Do you have a Barnett lock up in it? And your wheel base is 6x?

I think I can get a 9.9 with a 1.5 60 as well. I think its between 60 and 330 I'm loosing out when comparing to a couple of the other guys running 9.4s-9.6s in my class are 1.3s and 3.9s. I'm running on average a 1.5 and a 4.1-4.2, so it seems a big chunk of my time difference lies in that first 330ft, but they are also hitting 135-140mph. Where as I have been peaking at 130mph it seems. I need to find some more MPH in the big end and keep working on my launch. The seat pan I made was a huge help, I really think it's going to make the difference in my 60 and 330 times, just need to find more power after the 8th. thinking I need to drop to the 32T crank which will put me at a 4.25 final and have me cross at a higher rpm in 5th. Thoughts?

Barnett scorpion 6 spring no lock up and 61" +/- 1/2". Swing arm is +4 at the end of the slot, I'm set at about 1/4 back from front of slot. Front end is -2. Last time I had it strapped on the lift and all the way forward it was just over 60 1/2.

Agree with everything you’re saying. IMO if the shift light is not on in the traps you’re leaving something on the table. Why it’s not on is the question. If it’s e.t. You’re after work on the 60 first.

Imho you do not need more power to run quick and fast. You have the power and imho if you spend more money looking for power you’ll spend a lot of money and set yourself up for failure. You know what needs to be done, 60’ and 330’ work, you said it yourself. Do that and the bike will fly. Just my 2 cents

Agreed, seat time will be the key, I have plenty of room for improvement. I still want to go lighter on the sprocket this winter just because, so stuck between the 32 and sticking with the 34, worst case get the 32 and go down on the wheel sprocket.

12.0 50 mph first pass. Up and down a bit. 10.53 at 65mph. A few shifting issues with the rider. Hopefully a good turnout tomorrow!!! First few passes he didn’t like the bike, but with some runs and creeping up the rpms on launch he’s liking it. Slow on r/t, but that came around after he got comfy. It’s game time tomorrow! He did like the non violent launch compared to the cr85. I didn’t test as I was busy helping max with a few things. I did pull my 375 spring and install my 350 clutch spring. It’s not as aggressive, quick or fast , but it’s more forgiving when the track prep changes and is consistent.

86* degrees today, tomorrow with shxt DA, but
We don’t care!!! Winter is coming and good luck to anyone racing tomorrow. We are tossing Max into the money bike class with me if he Chooses. If not, he’ll run jr and I’ll run trophy bike and the last money bike race. A few old friends showed up tonight to get a piece of the pie 🥧 so competition will be tough!
