Description of the car is in the sig. It dyno'ed at 363 RWHP, 356 RWTQ. Track times are consistent:

60' 1.721
330' 5.172
1/8 8.004
MPH 87.48
1000' 10.468
1/4 12.546
MPH 109.1

I've launched both by flashing off the converter and by loading up to about 2500. I also run skinnies and ET Streets. Doesn't make much difference. I'm looking for things I can do to get closer to 12.0.

Precision offers a free restall. I'm not sure what the limits are for the Vigilante but I'm hoping a bigger stall will give me a better launch.

Any advice on a stall to go to? Anything else to ask for? STR? etc.?

Not really worried about drivability too much either.

TIA.

 

4400 is probably the highest to still see gains. TCI 4400 or Yank PT4400. PT is proven, TCI is more affordable.

 

Go with the Yank 4400. Youll be happy, it cost more but has proven results!

 

Thanks for the input. I'm more interested in restalling the vigilante than buying another converter right now.

If I was starting over again that might be another story.

 

Have you ever had your car dyno tuned, Those #s seem abit low for your mods, whats the D/A.

 

It was dyno tuned @ MTI with LS1 edit.

D/A was about 1400' last time out. Had 4 out of 5 runs within 0.1 sec of the list above.
