Re: Best boost to launch at?
I think some were posted in my project never ends thread, or nats 07 picture thread that matt took.
Basically it is a triangulated 4 link, started with an Art Morrison universal kit. Lower bars mount almost where the front spring perch is (if I did again would probably try to reuse stock front leaf spring perch.
The top bars are triangulated, eliminating a panhard bar. Mount to custom mounts on frame, angle in toward center on the rear diff.
I mocked everything up without the body on, my calculations of ride height were off and the lower bar was angled down toward the front. Made the truck spin rather easy.
Drilled a new hole moving the mounting hole up in the front, they now converge somewhere around trans bellhousing I am guessing. Truck instantly launched much better.
1.6X at 4psi on cheap street tires and 4k lb truck.
Never got to turn up the boost, this year I hope. Want to see a 1.55 on street tires.

I run four Mickey Thompson drag radials mount on stock rims on my Typhoon. I usually run the front tires at 22-23 psi and the rears at 18-20 psi. I've cut a best of a 1.61 before adjusting the suspention. I hope to be in the mid 1.5's this year with a new torque converter.
Hope this helps,
Nick

My latest Sy seems to like 18psi on the street.......solid motor mounts, CalTracs, BellTec drop leafs, ATR sway bar, 17"BFG drag radials.....the ABS delete unleashed a new animal! I could only build about 9-10psi and the truck would creep forward bad until the abs delete was done last summer.

I want to Congratulate You, You are the only 1 that I have heard of, still running the KA-Boom chip. Even with 104 race fuel that is brave, real brave.
