need a little more tire hit
 

i have a 2x3 chassis strut front four link rear. i need a little more hit im running lees hp than what was in it. im running a 496 glide 4500 stall leaving at 3800. i may need tires i dont know how old they are. im running 32x14 hoosier. my best 60' is 1.36. its just not hooking like it should and it may go a 1.41 and the next pass a 1.36. what should i screw up first?

If you are not sure about the tires, then that would be the first thing to look at. With your 60 ft. times that inconsistant, it would be a good place to start.

TS1955

i agree with ts, thats a fairly big swing between runs if all else is equal. in other words, no chassis adjustment between rounds.

i ordered a new set of mickeys today well see what happens

It may take a few run to wake up the compound on those mickeys, but after that, i think you will be happy, what rear shocks are you running?

double adjustable they are soft

You can get more hit by raising the top bar a hole, i was on the bumper because the CG was off so bad on my 4 link. Haven't been out since the change (dropped it 2 holes) and scaled the car, put 30lbs right side, but maybe i'll find out friday nite T&T if it don't rain, been rained out for 1 1/2 month, we only race and T&T every 2 weeks.

Zip.

how many clicks do you have in compression, stiffer compression and softer extension, will get you more hit.

Zip, I wonder if this is the difference in the door car vs dragster, but we've lowered the top bar *front* holes to get more hit, shorter IC. Must be it is different with a door car, was thinking this would go the same for all 4 links as they are the same concept. Just wondering here thanks for the info :)

mines not super fast 1.36 60' my front tires never leave the ground or not enought that you can see it anyway.

I don't know David, but when layed out with a chalkline the CG (old setting) CG was right behind the front tire (car on the scales) 1450lbs on the rear 1766lbs on the front. Dropped the top bar 2 holes to get closer to the CG and set the preload to 30lbs right side. As i said i have not run the car since the changes were made, but before the changes it would pop the frontend 4 to 5' then fall right back down (no torque with the 377") it would normally 60' in the mid to high 1.40's, total weight 3216lbs.

Zip.

ok guys the new tires didnt do it. my 60' times were 1.377 to 1.45

have you got any video?

no

More bite
 

What is your tire pressure in the slicks? Some video would be a great help. Stripe the rears and get some video of the car leaving as viewed from the side. Have you tried stepping up the launch RPM? Are you shocks bottoming out?

i went from 6 to 7 pounds 1/4 1/2 3/4 didnt seem to change much i dont have a video camara i tried leaving at 4200 early in the season but seemed the 60' was better at 3800. i dont think its bottoming out. it had about a 100 150 more hp than my motor plus it was aluminium headed and mine is steel headed so more hp and a little less wieght. i think im going to do what zip said and raise the top bars a hole and see what it does

if that helps, then you were hitting thr tire too hard.
