1998 indy 500 liquid
Sled only turns 7000 rpm and top speed of 65 mph.
IS the Rpm right? I know the top speed could be higher.
I got 20 top gear, 40 bottom gear in the chain case.
epi clutch kit, orange primary spring with 50 gram weights
and a purple secondary spring. Im not sure on what the helix angle is that came with the kit.

What is the red line on the engine?
I have read in another thread that speeds can vary from 75 to 90 mph!
So Im way low on the speed!
Thanks

you may be low on speed, but with the clutch kit and gearing it sounds like from a dead stop that thing will pin your ears back!

so it depends on what you want, hole shot, or speed. your going to give up a little of one,to get more of other
