I don't have Dyno plot of previous spec but it was jm1300r and ran a 9.9 @ 154 mph on r888s at totb, and then ran a 9.7 @ 161 mph with a 1.7 60 ft on 18" rims with drag radial on it

By my plot I got from rips 160 mph at 1800 kg is 1250 hp, and 154 mph at 1800 kg is 1100 whp

Ignoring the time as were looking at proof of power not grip, even the 161 mph it's done in precious spec proves I believe previous spec was actually above 1300 crank hp at 1800 kg

It now has about 300 hp more but the turbos are huge so I don't know how it's going to affect the launch, I will make sure I have my vbox in the car for any runs I do so I can analyse the data as that should show me any dips in mph Vs time

Buzz pattar at jm1700r spec has run an 8.3 @ 171 mph but that was with rear slicks on 18" rims, I'd imagine they were bias plys aswell as the car gets out of shape through the run and the driver said he did lift at one point !

Jurgen said mine should do about 1700 hp if we run 45 psi of boost on e100 but I said na it's ok 1560 will suffice for now lol
