What are you talking about when you say windows cut out and clipped ? ypy spring what does that change and where do you buy them , dealer ?
i ran 121mph in 600 ft.with a simon cpr turboed apex, not much traction at the starting lights. feb 10th in fort atkinson, wi. might be going for a 1000 ft radar run to see what it does.

the closed windows on the track that the sliders run on is what i cut out and made it a fully clipped track,the spring i got at my local dealer,it helps lower the engagement rpm and it is close to the same on top end so you dont have to change any other setting,better gas mileage too......flybyu....that is an awesome speed,i see a local guy the other day at a 1000ft radar run on the lake get a bunch of 129mph runs,sounds like you would have that speed at 650-700 ft,good luck on that
