unless your really heavy or you are on the brakes hard in and out of turns I think you would be shooting yourself in the foot on the 13 driver combo.

I run a 1/8 mile that has pretty tight turns. I am always on a 15/61-64. I'm always near the front. The 13 wont have the getup you need. I'll also point out that our predator isnt completely stock, and I target 51-5400 rpm.

Thanks I’ve been running 15 / 63-64 one guy told me try the 13/60 so I would have to get a 13 I have the rear sprockets to change if I stay on a 15

The 15 is going to be your best bet. Forget the others and just find a rear gear that works better for you.

You'd be out to lunch on either one, Jaymancds is on an 1/8th with a 15/61 to 64 BUT turning 5100 + If your stock you only want 4800 so that would put you at a 15/58 provided your track only makes mid momentum like where he's running, Here we have a SMALL 1/8 mile but it grips up real well and makes flatfoot throttle momentum and gearing is a 17/ 58 BIG DIFFERENCE, If you only have a 15 driver start it with a 15/56 however If you have a 16 driver start it with a 16/60 so you don't start gear bound and then go from there, YOU FOR SURE DON"T WANT NO 13/60.
Good Luck !!

Just because your allowed it doesn't mean that's best, If it's STOCK out of box to race it at 5300 rpm your killing it, beside that the 5500 max rule should be on the stand, Where are you racing it at ?

I run between a 15-57/60 on an 1/8 mile non momentum. I purchased a 16 and I think it’s gonna help. I’ll try it next outing.

Pap , come on down to 2 Brothers on Oct 11th . Box Stock Nationals .
I don't like putting that large diameter gear out back , tends to dig into the track and could cost you a race .
