Al that is because on a dyno a gear ratio is a gear ratio, It will not show a gain but that is certainly not the case on the track! On a momentum track a 16/63 will outperform a 15/59 every time. I've tried it multiple times just to prove it to myself. Why, I can't say.What I find interesting is; I've never heard of anybody finding these 2 tenths on a dyno. I can't help but think; if you're getting more HP to the axle (I'm pretty sure that's what you'd have to do to go faster) why does that not show up on a dyno?
I can't figure it out either. Do you have a dyno? Maybe a friend with one?Al that is because on a dyno a gear ratio is a gear ratio, It will not show a gain but that is certainly not the case on the track!

Nope, not yet. Hoping to have one soon once I get my bigger shop built.I can't figure it out either. Do you have a dyno? Maybe a friend with one?

Can you explain the reason for having to change at one tooth down. Did it turn more RPM before you took the tooth off? What happened?From our testing when we would say go from the 16/63 to the 15/59 mathematically we end up needing to drop down a extra tooth on the rear and vice vs. when you are adding a tooth to the driver..... food for thought
It's interesting to me as well, I'm still curious as to 100 % details of timing between your test, I see week before you lead on a 16, then i see 5 min scrambled to prove, still doesn't paint the picture of exact details full account, also 100 % details on tires for all the runs.I'm not trying to convince anyone at all. I'm just sharing what I found. I was convinced 15 59 was going to be faster. Week before I lead the race on 16 63 thought for sure with someone pushing 15 59 was going to hold the lead. Nope switched 2 tenths it was more like 5 min scramble to get back on track to see if my experiment was correct. I seen results thought same thing promoter thought. But now I have enough info that I'm not going to 15 again. I have someone in clone mediums doing the same thing with me. He laughed cause last race in 15 driver he finished back of the pack. This race 16 driver he was swapping with leaders contending to win.
I'll let everyone know if I figure something new out.
This is just interesting to me.
Also 2 tenths change not one lap 2 tenths. Mylaps are consistent. That is what I meant 2 tenths every lap. Not 2 tenths on my best lap. I went from front runner to back of the pack.
I agree with you 100%, and that's my point.Your still not comparing apples to apples 100% with different on track runs even if only 15 min apart, don't matter if it is the same set of tires, same number of laps, there are a lot of contributing details that come into play that can show 2 th difference either way that has nothing to do with the different gearing combo's being tested. But hey confidence is probably worth 2 th as well !!
