Got the car dynoed. First run at 16degs timing and 11.6/1 AFR was 617rwhp/572rwtq. We wanted it really safe so we pulled the timing to 14degs and added fuel to 10.5/1AFR and made 601rwhp/538rwtq... I am seeing 10psi at 6000rpm, thats were we stopped. There is more in it if I run it to 6500rpm. The other lines were with the previous Maggie 8psi...I made no other changes from the Maggie to the Paxton. By 3700rpm or so the Paxton is making more HP and TQ from there on...I'm very happy with the results... Mods in sig. stock LS1 bottom end and stock heads...I did all the install myself.

 

thats sweet, is it an A&A kit, or who did the work
either way great numbers and setup

This is the ECS(east coast supercharging) kit Paxton Novi 2000 and a huge intercooler. A&A uses a smaller Vortec unit and a smaller intercooler...

 

Congrats on your numbers.

 

Nice numbers in a beauty of a car. What's your intercooler setup?

If your IAT numbers are under say 150 you probably don't need that much of an AFR safety net. Im running ~8# after the throttle and FMIC, and I'm running it at 12.0 AFR with no knock and 25 degrees of timing. Pump gas (91, NorCal). I'll bet 11.3 would be still very conservative but safe, and that's pretty much the Rich Best Torque point for our Chevys.

Are you seeing any knock?

Your dyno looks good man dam good numbers

 

Congratulations on the install and the outcome!

I'm lucky enough to be relatively close to ECS, so I had them do the install.

How does it compare to your previous SC?

IATs seem to be right at 10degs above the outside temps. The intercooler is huge. 3 1/2" core x 14"H x 28"L ....

 

James what suspension set up have i know off topic but i have limited time and this dam thing takes 10mins to load

 

nice setup man

 

very nice, but I think you were plenty safe with your original tune. you lost a significant amount of torque.

 

thats awesome on a stock bottom end!! great numbers
