After getting rid of my rear mounted fuel cell, and putting the four gallon cell in the front, I had an opportunity to review some run video.

Check out the back tires on the launch . . . :nonono:

You could always ballast the rear of the car with lead, but I'm sure that adding weight is not the direction you want to go.

Have you tried playing with the shock settings to get the car to sit down better and not unload the tires? Maybe try some stiffer settings first. You probably need to be in the low 1.3s to get where you want to be, right?

Yeah . . mid 1.3s should get me there. I'm going to adjust the suspension (shocks, LCAs, and Anti-Roll) and play with the tire pressure a bit tomorrow night. I probably also need to have a look at my pinion angle. I don't want to add weight.

I also just got bigger injectors so I can, hopefully, get the car to quit falling on it's face on the big end.

I don't know if you've met him, but there's a guy named Todd Beaudoin here in the valley with a 79 Mustang Pace Car replica - he runs low 10's with an NA 347. He has since backhalved the car, but used to run stock-type suspension and could 1.3 60' with a small tire. I think he did some voodoo with the rear suspension (specifically the UCA placement and geometry) that helped him hook harder, so if you see him, have a chat. :) I think he's a relative regular at the track.
