Spring Clamp Question

[OregonDMAX]

Thanks for the tips Bac. Not new to drag racing but always had rwd and it's a totally different animal. Maybe I'll keep my rear shocks then and just switch the front to the Ranchos. How much difference did you see between clamps and caltracs?

They are way too different to compare one to another. I run both.

I was just curious since he switched what his before and after 60s were.

Well i got a chance to go do some testing tonight. I tried launching by RPM and just referencing boost. I started at 2000 rpm which was 12 psi and the truck hooked and left pretty decent. I stepped up to 2200 rpm which was 15 psi and the results surprised me. The tires spun, but by the seat of the pants the truck felt like it left harder than it ever had before. The next attempt was at 2300 rpm which was 18 psi. The truck started pushing thru the brakes and when i launched it spun bad and was all over the road. Unfortunately i didn't get a chance to repeat the 2200 rpm launch to see if results would repeat.

Sorry, didnt see this. Usually 1.7x + with spring clamps, with Caltracs usually in 1.6 - low 1.7 range.

Thanks for the info. I want to run 11.99 on the 33s at street weight. To do so I will have to get it to 60 really well or a bigger turbo and fueler and i think getting it to 60 would be much cheaper. We'll see if I can do it this fall with a nice cool day and good DA.
