[-Alex-]

Okay, i went with these ratios ( 3000rpm ), theoritically 250km/h is achieved at 6570rpm.



1. 3.44= 25.5 km/h

2. 1.93 = 45.5 km/h

3. 1.3 = 67.7 km/h

4. 1.00 = 88 km/h

5. 0.77 = 114.2 km/h

Also been talkin to Thorsten Pieper, i am going to buy his bare heads and stuff them with type 4 48x38 valves and JPM springs and retainers. And little porting







One finnish guy said by looking the pictures that JPM heads are a lot of better and theirs intake ports are better flowing and more straight than Thorstens heads. Yeah right

I cannot see the difference..
