Dyno numbers and track times

[FenixNR]

Finally got my car up and running on a base tune from Tillman Speed. Had to datalog some AFR's for him so I hit up a local dyno. I'm running a paxton novi 1200 with 39lb injectors non intercooled. I am on the stock pulley for now, and I made two runs without meth injection and one with. Without meth, I made 399.8 whp, and 364.4lbs, with meth since it came on a little eary it was 385.2 hp and 356lbs. I was very happy for this. Kinda scared me with AFR's a little, but the dyno guy said its pretty close to dead on. 12.1 afr when getting into boost, then after in boost it drops down to 11.1. So I took it to the track the next day, since it was our first open day, remember, only mods for my car are that and lowered on tein springs. Pulled off a 12.87 @ 109 for my best 1/4, being I had a 2.3 60' thats not bad. And a 12.94 @ 112 for my best mph. Very pleased with the kit, also let it cool off between runs. What do you guys think?

MPH seems about right, but the ETs are slow. Need to get that 60' down about a 1/2-second.

LOL, my only run with my car last year is almost identical with your times... My 60 ft. was brutal too, and my mph was similiar as yours as well as your times..BUT...this year will be much better..TRACTION!!(and cams and proper shift points will help)

Our track was hooking REALLY well, I just didn't want to break anything so I was super easy on it. We had cars pulling the wheels all day there.

I looked at your datalogs and they're definitely friggin nice air fuels. Are they before or after the cat? I can lean out the top end so its about 11.7 all the way throughout. You'll pick up some power, for sure.

Chris - dont you mean rich'n? 12.1 seems a bit lean already @ WOT

Post #1 says it goes to 11.1 in boost...

It ramps from 12.1 down to about 11.7 and holds fairly steady, and then drops down to 11.1 in the higher RPMs and I'd like to keep it a flat 11.7.
