I liked the video. It runs good. Got air bags in the rear?

Nice run on the vid! Keep pecking away at the tune by trial and error is all you can really do.

Have some one stand behind the car when you are spooling the turbo to check if the rear bumper is staying parallel to the ground.  If not, an air bag or a stiffer roll bar may be helpful.


Watch it on an actual launch as well at the strip

Kevin Slaby's rear upper control arms relocation kit is also a good idea given the poor geometry on a GBody as well

I didn't see any real issues, at this level. That is why I guessed air bags. Typically, a G-body is beginning to show symptoms @ 1.6 short.

I would not worry about it until it breaks loose as the rear unloads. They typically squat on the hit and unload in about 10-25 ft. This car apparently has good rear shocks and a smoooothe power delivery.

Anyway, you can video the launch and slow it down to find out. You probably won't feel it.

15 to 20 at 3100 to 3600 at that you think it would be wheels up

117mph is solid horse power. Hooks well. Or seems to. Short time? What about the other splits? What kind of mph is it picking up In the second half?

I agree.  Something is not right at that point.  It should be wheels up or blowing the tires away. I would expect a 1.5 short time

It acts like it hits full boost after rolling out for a bit. Is it spraying alky while your spooling?

or, the converter is not doing its job and is absorbing the "Leave" instead of handing it to the rear tires?

I would listen to Lonnie and Julio at this point. [converter]


With a 3500 n/l I didn't even notice it was there until I got in a stocker. I certainly never got the, wait for it to hit, people talk about.

I’ll post time slips tonight on the split
Turned Alky of for a short 60 foot left leaned out to 12.2 no improvement in 60 ft time
Tried the 2 step at 3600 worst 60
Got enough data and time slips for Lonnie to restall the converter to best Mach my combo.
