I realize that I should probably pull timing out to manage traction after the hit, but this is just a simple street car with a small plate kit. I am running radials, and track prep is not the greatest, when I have it come on right away, it would spin for 30 ft or so. I have a NOS mini progressive on the car, would it be worth it to try to delay, or progress the hit? The track is normally packed, I'm lucky to get 2-3 passes in, so I'd like to get an idea of where I should start, then I can dial it in from there.
I should probably upgrade the rancho shocks on the back, but I'd like to work with what I have for now. I think I might also go back to slicks just because of the quality of track prep here...

I had a friend that was running deep 9s in the 80s that would tune his hit with different length hoses between the plate and solenoids. Looked kinda goofy with a coiled up hose, but he would always get that car down the track. He had several hose sets that were staggered to sharpen, or soften the hit.

I did do that on another car actually, part by design, part by accident. The N2O noid was under the dash, then I had a ~2' line running through the firewall, same pill in that car hit much softer.

What type ignition box do you have? If MSD programmable use launch retard or gear retard. If you decide to use a progressive I suggest the Leash progressive, simple to wire and use.

That's makin time! I'm hoping for .50's this year with my barge. I think it's gonna need a little more jet depending how early I can get it all in.
Here is a Monte trick, hit it as hard as you can for the first two tenths, then pull your launch timing out. Monte said, everything dead hooks for two tenths...
I've been thinking about this a bit...He was talking about timing that you'd pull in addition to what you pull for the nitrous(step retard), right? The car does fall on it's face if the initial progressive is set too low on the off chance I'm trying to get it down bare asphalt. Probably because I'm pulling all the timing at the hit, then ramping any launch retard back in over time. It's a balance between hitting the tires hard enough and keeping it planted, especially on an untreated surface.

A tire needs to be hit and held there to work, especially a radial or a slick on a marginal surface. Hit it hard and hold the tire down with the shock. So....hit it hard but what works well is to hit if for a tenth or two, then pull your launch retard and ramp it in. This helps hit the tire, keeping it there is the job of your shock. To go "fast" you need a good double adj shock. Tight compression keeps the tire planted. What also helps a lot is keeping the front suspension off the limiter. That's either a lot of travel or a tight shock ext setting or a combination of both.
....BAD A$$ STREET CAR.....

Good info! Thanks for the help! I finally broke down and bought a set of Viking DA's all around. Can't wait to get them on the car and start playing around. I really only got one hit on the new motor last year so this is going to be a learning curve for me.

How did you go about this discovery? That's still fast as hell
Ok, just one nipped piston, and some other issues. Changed the carb and it's real fat. Wire for my rpm switch for electric shifter fell out of the msd tach conn/output, banged the limiter. Got all the parts and ready to start reassembling tomorrow . Hope to make a decent showing at monster Mopar next week.
