I've never been able to determine much at launch on dry pavement with mine. At speed, sure, but not from launch. The surface is just too uneven and unpredictable. Doing essentially dry burn outs on untreated surfaces like that, mine does the same thing, though with a bit less climb than yours. I think your experience will be way different on the track, after a waterbox smoke session and a launch on a treated surface. Don't get too discouraged
That thing sure sounds good and healthy !
X2, I agree, mine would just boil the tires on that surface. I gota have a well prept drag strip to leave hard.
Your other ? from earlier....Just my opinion below.
1) front travel from 4 to 5 " = great.
2) front shock calvert 90-10, rear shock at 4 click to soft is ok ??? = If it hops at to track add a click or two.
3) sway bar removed. =Yes
4) all bumper bracket removed. =Yes
5) battery on the trunk. =Yes
6) exhaust removed ( only headers and 15" extension) with EVAC. =Should work well.
7) connecting frame. =Yes, but add a roll bar or cage later for safety and more strength.
8) pinion angle to 2 degree nose up at 2 degree nose down). = On a leaf spring car I have been told 4 degrees or more, maybe less with CalTracs but I don't know for sure. Important that you are measuring rear end is nose down in relation to the crankshaft/transmission main shaft. NOT the DRIVESHAFT!
See diagram here http://www.markwilliams.com/driveshafttech.aspx
9) caltracs at zero preload ( i dont understand if is better at zero or 1/2 preload i dont see change ) = A half turn would help control wheel hop and help with pinion angle change under load. I think with preload of a 1/2 turn you would be able to run less pinion angle.
10) tires screw installed with tube , Tire pressure 11 psi =Or start at 12+ and work down. hopefully you will have time to test and tune the things that you can adjust like shocks, tire psi, launch rpm and so on.
IMPORTANT...With a clutch car you actually need just a little wheel speed (spin) appox 2 to 3 or more turns then hook.
If it dead hooks, somethings got to give. One of 3 things will happen, 1) broken parts all over track 2) engine bogs down 3) clutch slips. I allways say the cheapest thing to break is traction.
11) car weight from 3650 to 3490 =Great reduction!
with all this work, as it will be my 60 ft?? = I'm happy if it improves any, atleast I'm know I going the right direction.
for you rpm launch is ok at 4500 or is too ??? = Start low and work up, 3500 and see what happens. Remember don't break it on the 1st pass cause you want to prove something.
Can I have spaghetti too!
