Predator 212 hemi question

[fatfrog]

Our track has started a new division its a predator 212 hemi class, stock right out of the box, trying to figure out gearing and rpm wise, have never messed with one of these right out of the box, governor still intact, its a 1/9 mile banked asphalt track we have to weight 375 and open clutch, have a bully two disc clutch was just wondering about the gearing and rpm thanks

Target rpm’s will be 4800 , do you know if you can flatfoot the track.

 

[fatfrog]

I would believe so its a very banked track with some grip

 

[fatfrog]

So would a good gear to start be like 16/60

If indeed it's flatfoot momentum to big rear, with 16 front driver a 56 rear should be close.

And if its not a flat foot momentum track?

Few more on the rear , maybe even closer to your 60

I can flat foot my local track at 4800-4900rpm with a 14 driver and 62 rear but I don't have the speed still. I've been messing around with it. I'm a heavy guy also fyi.

Probably more air pressure, which track, which tires, current air pressure ?
