F2 is much larger unit. F1R will not support 1200rwhp. F2 will take more power to turn than the F1R.

Im hoping for 1100rwhp on a 75-125 shot of spray. 900-1000 on meth

What power level NA should I look for to decide F1r or F2? motor will be broke in NA

What car do you want this on? Because the F2 won't work on a 4th gen. I mean there is no actual kit for it, you would have to fab something one of to make it work. For an F2 you would nee to push over 500 or so to the tires.

Not a 4th gen. I think I will make over 500 at 9.0-9.2 cr. Cog drive a must with either

I have to say that I disagree with the over 500 rwhp statement.

I witnessed a guy running an F2 on a stock size mod motor at the tract the other night and it seemed to be working very well. 40 psi of boost on a 4.6l with stock ported heads, aftermarket cams and a carb style intake. Car was running high 5.20's all night on a shitty track. I seriously doubt a 4.6l in any configuration (especially boost friendly) would make 500+ to the tires.

Then again, I might not know a damn thing...............
