I went to Atco Tuesday night to try out the suspension (and some other) changes I made to my car. The results from the last time out are in my sig.
This car is just a toy that I don't take to the track much because it cost $300 to get towed home once! (broken axle) I would go more often, But I can't justify the cost of a trailer. Anyway...
After I bought the drag radials, I read on here that they are for auto's. Being that I'm not a serious racer, I tried them anyway. When I got the 12.003 last time, I was dumping the clutch at an unknown rpm. All I had was the stock tach. i was not getting good launches. The launches are even worse now. Best of 11.88 @ 121, a 12.06 @ 121, and a 12.88 @ 118 where I tried to slip the clutch, and boy did I. I aborted two runs, they were brutally bad. (Wheel hop, missed gears, you name it!) BTW, the tires are 6 years old. (DOT 3810)
The changes since last time:
-Skinnies and light wheels, front and rear. Same rear tires.
-Approx 200 lbs. removed. Weighs 3140# w/ me.
-Battery in rear.
-Eibach front springs w/ 1 coil removed. (It sat too high.)
-Stock 5.0 rear springs, 1 coil removed.
-Strange 10 way struts, shocks. Front full loose, rear on 5.
-No front sway bar.
-2.95 1st gear. Astro A-5.
-Fidanza Alum flywheel.
-Mc Cleod 260570R clutch disc. (Per Tony at Astro, needed a 26 spline) Used with existing King Cobra PP. No "R" on this one, but I believe this is it: http://www.mcleodracing.com/index.ph...x-26-yes.html-
-HPM lower control arms.
-Steeda adjustable uppers. (Solid mounted at body, stock bushings on axle end.) Pinion angle- 3* nose down.
-Shift light, tach. Shifted mostly @5800. (Things were happening fast!) Through the traps @6000.
-2 step, set at 4300 rpm.
-MM full length subframe connectors.
-No roll bar, though I expect to need one when I get it to launch.
I'm thinking I need to get bias tires. I want to use DOT, because I don't want to swap tires. I also need more practice. I never raced a stick car this quick before. But I wasn't getting anywhere fast with the DR's. It either hooked and hopped, or spun through 1st. I was trying to slide the clutch, but it was hard to do. When the car bogs, it's hard to control my foot.
How about these? https://www.summitracing.com/parts/mtt-3551
EDIT: I just remembered that I had a chip in it the other night that wasn't in it the last time out. LaRocca burned it in 2000. Maybe that accounts for some of the mph increase.
2nd EDIT: I forgot I also changed the flywheel and clutch disc. Probably important, huh? Maybe also responsible for some mph and a reason it's hard to launch. I added them above.
