Nor should you, it's just going to make it a touch more difficult...especially on a less then well prepped track.

How many passes do you have on the DR's? Mine took a few good burnouts and about 50 street miles before they started hooking well.

Agreed.

Wish I was closer, I'd love to help and watch you make passes with that combo.

Burnout: Next time you go out, try to go out with a buddy. Have him watch your burnouts. A problem I've had, as well a few friends, is we think we're doing a monster burnout and actually we're not getting the tires that hot. I've been focusing now on going like 5 mississippi up to 7 mississippi. I've also been doing my burnouts in manual mode though you have so much gear I'm thinking you don't have a torque problem.

Tires: Try 18 cold.

Launch: I'd try stalling it up to like 1500 and then for the first pass or two, I'd get into the gas fast but not stomp on the gas. Roll into it fast. If you spin like mad, even after a good burnout, I'd roll out even slower, just to get some decent numbers out of the car.

Track: Compare notes with other races. See what they say about how the track is working. My closest track, like on a Friday, is good for a few hours after opening but goes away by 9PM.

You can "tune" the launch/60 foot if you have software or have your tuner do this via power management in the base timing map, or just get the right tire that you should have to cut a good 60 foot time. Just my 2 cents anyway. Also, one thing I hate to see, is the phrase "giving up". But, to each his own.

Another thing to note is since you have added a few horses to your setup you might be doing a one tire burnout. Have someone watch for you and make sure both tires are spinning.

Do not forget the alignment. If you're set up for the street only you will not do very good strip. I bet just by changing the alignment little bit you will do much better. I know there's a vendor or two That posted a good set up for a street/strip use that won't eat your tires up.
Some cars will hook up good from the factory some will not just too much variation from the factory.

This is the very issue that improved my 60' from 2 to 1.7 and got me to the 11 sec. You need a drag alignment front and back. I also ease into the throttle to reduce spin...launch from idle on last yellow and peddle on the floor on three count. I will be at your track when temp get cooler, I like that track. Also how long and how much practice did it take you to hit every green in regulation?!!

Agreed.
I have about a dozen passes on the tires and about 200 street miles.

Somebody please explain "fast roll" to me.

I hate to "give up" too, but the definition of insanity is doing the same thing over and over and expecting a different result.

The rear end has the JRE Posi-mod in it, but I'm not sure that is 100% foolproof. I seem to be getting smoke from both tires.

I have had the front and rear alignment set-up for the strip. Using Pedders recommendation for the front and Hendrix Engineering recommendation for the rear. Those seemed to really help my 60' times when I was on Nitto 555Rs at about 370 rwhp. Haven't changed the alignment for this set-up.

Easing into the throttle is a very ambiguous term for me. Whenever I try to "ease" into the throttle I seem to end up being too slow. Can't seem to slow down to go fast.

I still don't hit every green, still have about 10% red lights (impatience). Shoot me a PM when you're coming to Silver Dollar and let me pick your brain.

Yes, I went down there last December after Silver Dollar shut down for the winter. Actually put down my best 60' time and ET there on my previous set-up (370 rwhp and Nitto 555Rs). In fact the 60' time from SGMP on the old set-up is better than what I have had at Silver Dollar with new set-up. Thinking about going there again just to compare with Silver Dollar again. SGMP makes Silver Dollar look like a red-headed stepchild as far as facilities and track prep. The only down side is that it a lot farther to drive to get there, but may be worth it for the better facilities.
