Unhappy car falls on it face!

Ok I have a 96 Formula M6. I ran it about a month ago with the stock slipping clutch and turned a 2.09 60 ft and ran a 13.74 @101.8. I went to the track on Saturday with a new Ram HD clutch in it and could not get a decent 60ft. I would heat the tires up real good and tried lauching at 2500 and it squated and then fell on its face and bogged bad (like it was going to die) and then took off to a 2.45 60ft. I was told the rpms were to low to go higher, so I tried 3000, 3500 with the same results. I then tried 3800 and it spun the tires over then hooked and bogged. I even tried heating the tires and then just releasing the clutch and punching it off idle and that didn't work because it still bogged. If I do not heat the nitto's it will take off but the tires will be slipping. I can not ride the clutch off the line because the clutch engages all at once, so what should I do?
exact setup : stock LT1 with the airbox removed, Ram HD clutch, nitto's with 20lbs, cut-out on exhaust

Not true that you cant ride the clutch off the line, you just arent giving it enough rpms or not trying hard enough, with my Stage 3 ceramic clutch which is basically on/off, you can ride the clutch out, it just takes 3-4000 rpms to do so, or maybe more. Other than that noone can tell you how to do it exactly, you just have to keep trying. Basically your problem is that your car isnt powerful enough for the amount of traction it is getting if you just drop the clutch at lower Rs, and if you drop it at higher Rs the tires arent sticky enough to handle the power, so with your setup you basically need to ride the clutch out.

I agree with Jona.... your car is basically stock. You need to keep it reved up and feather that bad boy.

I will practice that. I guess since the stock one slipped I didn't have to ride it and I could just dump it, I will practice and see if I can't figure out how to ride it out of the hole. I could ride the clutch on my old Stang, but it didn't engage as quick as this one.
Thanks Zack

If you clutch is brand new, thats your other problem. It needs a good 500 miles at least for break-in
