Like the title says which would be better for my setup? Solid roller with TFS 245's and most likely a Fast 92 setup. Been told 42's before but the more I search the more it looks like 42's won't be enough or be right at the edge. Thanks for the help.

Here is a quick calculation based on 675 FWHP N/A. I'm not sure what kind of power or RPM your shooting for but if you make more than 675 FWHP you will be close to 80% duty cycle by using 42 lb/hr @ 3 bar injectors. They will fuel the motor but do not offer much room for more power in the future.

42's should work fine for you, 42's @3 bar flow 48.5 @4 bar, which will be good for about 700 HP.

We have some good deals on both 42's and 60's right now, PM me for more info.
