I did the first time i ran but unhooked it i will set it back up next time i run i'll set it for like 6300 and go for it!!!! Also take some weight out of that fat pig

these motors need to be spun real high, i shift mine just shy of the revlimiter every shift and the engines pretty stock. id shift that thing at 6500.

how are you launching the car? i see the 60' is ok but after looking at the 330' numbers it looks like the car might have bogged when the rpms came all the way down.


for instance i have run a quicker ET spinning to a 1.89 60' vs a 1.82 dumping the clutch at 5k and dead hooking because the clutch will slip a little at first and the rpms will slowly fall but they eventually fall to 3500 and the car falls on its face. so even tho the 60' was quicker the 330' and up was slower.

I tried spinning them and the tires grabbing this is my best 330 of the night ill tach it up higher wednesday and see what happens

what are you running for a clutch? you need to work the clutch pedal as long as you dont have a puck style clutch. basically something has to give and its either going to be the clutch or the tires. with drag radials it has to be more clutch than tire, theyre a good tire as long as they are dead hooking but seems like once they start to spin its all over.

fwiw im stepping up to 4.30s in my 99, the 4.11s are a big improvement over 3.42s but still not enough, has to do with the 2.66 1st gear in the trans.

I have a monster stage 3 clutch. i was thinking of doing 430's but figured the 410s are enough. Ill drop some weight see what that does. I want to add some quick power with some bolt ons.

you have the power, id spend money on making it all work going down the track. with that clutch your going to need a bias ply tire, full slick or a dot slick. too much clutch for a drag radial, theres no slip with a clutch like that, hits the tires way to hard.

put the money towards a 9" with 4.30s, a pst driveshaft and hoosier quick time pros. like mike mentiond a while back get an anti roll bar while your at it, a solid 24 or 25mm is a big improvement over the stock 19mm coat hanger. youll want lca reloc brackets as well.

Take the toolbox, spare ect out. Run on a 1/4 tank of gas. Weight makes a huge difference. Also compare da conditions which affects alot.
