tech speed for 100 mph class is 140mph.It wouldn’t take much to be in the 90 or 110 class. I’m pretty sure the tech speed is 120 for those classes. An LS with bolt ons would get it done.
to me there was a huge difference driving at 130mph on that road(last year entered in 100) vs driving at 110 on that road. ie- on the first long stretch to get your average up to 100 you need to drive a lot faster than you would at 90. Im sure someone will come along and do the math for me, but what Im talking about is the feeling. the road is shit. absolute shit. 110 feels sketchy as fuck. I cant imagine driving it at 150 in the 125 class.
we were cruising at 135 last year when the blower pulley came off. that is about as much as I would have liked. 110 feels a lot safer. plus you get up in that 100+ class and the cage/belt requirements change.
I think a 6 liter with a cam( i had 400whp NA) is plenty.
