LRT formula (proven across hundreds of road cars) with normal manual trans and say your running real road tires!
1310kg (real road weight FD rx7 with 1/4 tank fuel)
150mph (averaged over last 66ft of a 1320ft standing start test
= 870bhp
Your car should easily do that given your power band and "dyno proven power"
looking forward to the result.
You will see a road FD in the fast fd thread that has done a proven 140mph both at traps and via VBOX (at same location) with 1280kg run weight (anorexic owner and no poofter sub woofers installed!) and it ONLY did 525rwhp lol (385rwkw VBOX) real wheel power at track!
fact v's fiction
go test it, I'd love to see the actual results from this car

IT WILL KILL A BUGATTI VEYRON which only does 142mph in a 1320ft acel test and its weight is FUCKEN MASSIVE LOL!!!
