Looks good leaving, things went away right after this. I got 4 passes in last night and I'm still having traction problems. I bought a MSD 7531 this morning. I'm trying that next.

Look's like a real nice launch. But how much boost are U leaving the line at? Sound's like you are going to half to have a boost controller installed.

The track went away later on during the night on the last two passes. The one in the picture, on that pass, I took out 8 degress timing and ramped it up from there. Right after the frontend comes back down, it smokes the tires. It actually lost traction again about 80 to 100 feet out. I had two drag radial guys with me last night that run a 275/60 tire. They both agreed I would be better off with the MSD box. So, I got one. I originally intended to go with a stiff wall slick, but, I'm leaning towards a set of Hoosier drag radials. There are several classes I can run in, if I run radials. I should have the box in by next Monday and hope to get back down there by the end of the month. Not much fun burning the tires.:no:

I'm running QA1 front shocks and Rancho 9000 single adj. rears.

I'm far from an expert...and it's even been a while since I stayed at a Holiday Inn, but I did read the Doorslammers chassis book a while ago. (How's that for a disclaimer!?!?)

You're carrying the front wheels, which implies that the leverage you're getting from the rear is aimed far enough forward to do that. Doesn't that mean that you should shorten the lever (instant center I think is the right word here) so that it's farther back, and you're not pulling the front tires? Seems like that would avoid the unload when you come back down.

I'll have alot more information to read after I have the MSD. I'm not going to mess with anything until I have it installed. Anyway, here are somemore pics from the track.

The car looks GREAT! 2 things...........The first is it looks like a lack of tire pressure in the rears. They are crushing that tire pretty good. The other sounds like the same problem I used to have, when the front end comes down it is unloading the rear when it porpoises and then you are spinning the tires. I have double adjustable shocks on the front and I have them set kind of loose on the extension but I keep them stiff on the rebound so the front end can't come down too quick. You probably don't have the stuff to do that on your car but it is something to think about. Adjustable suspension components are your friend.:yes:

Thanks for the info. I've only got 8 passes on the car with this setup. I know there will be alot of testing with a small tire. It will take some time to get it straightened out.

I just saw your post about the drag radials. I didn't see what you were running earlier. The Hoosiers work well but they have a softer sidewall than the M/T and they are going to wear out quicker. I put about 35-40 passes on my M/T 325s and they still worked great when I pulled them. I am going to a 275 radial class this year myself and running the 28" tall tire the same as the 325. I run 15 pounds in the 325s with a 3300 pound car and I expect to have to raise that with the 275s because of the smaller tire patch has to hold up the same weight so it will need more help.
You will get it figured out and that box is a good tool to help with your timing ramps at the beginning of the run.

What power adder is on youcar? I do agree the tire looks like it could use more air.
He's running a Procharger F2.





Sheldon----you're yankin' the wheels man! The car looks great as always. Keep us up to date and let me know the next time you go to Moroso or Brandenton--if it's a Sunday I can make it.

Be safe, talk to you soon.

:turn:

I haven't heard that about the Hoosiers. That's good info. I ran M/T before and they lasted quite some time. Mostly street driving back then. Those suckers are expensive so, it sounds like the M/T's will be a better choice for me. I apprecitate the input.

Sheldon the car looks staight and level coming off the line. Question is what do you have your back shocks set at full soft or are you loading them any?
When your off the line the boost is coming on harder and over power the tire by the way it sounds....
Scott go to the track with you?
Good luck and keep us posted
Paul


Hey Paul, Scott lives about 3.5 hours away from me. We have talked about meeting up at a track closer to his home. Bradenton and Immokolee are much closer to him. That may happen. As for the shocks, they were set a 8 on both sides to try control separation. As for tire pressure, we were moving up on that as the night progressed. As you know, small increments for everything so you know what is working and what is not. I am looking into renting the track with some guys once I have everything in place. I think that will be the best bet for gathering knowledge in a short time. I don't have alot of patience (with this) so this is really tough for me.

I know some one has mention this B 4 but have U consider going to double adjustable shocks in the rear? I know I am as soon as I can afford them.

Anything you can do to get a little more travel in the front suspension? Looks like even 1 inch would let it get up on the rear tire a little more. The more travel the better, especially with this small tire stuff. That's where I would start.
