I would love to see a follow up on some of these people with some upgraded drag radials or stickier street tires.Good job regardless

Worth noting: When you lower the pressure on drag radials you actually hurt your top-end MPH a bit. DRs really help you get out of the hole when you get a full contact patch down, unfortunately all that extra rolling resistance slows you down once you get going.

Your best ET run:
Nrgy - MHP Tune, MHP Catted Headers, Carbonio Airbox, Street Tires
2.238 60', 12.547 @ 117.58 MPH (1/8th 8.323 @ 92.26 MPH)

Be sure to watch it in 720p and crank up the volume.

The P31 results are very impressive and I am now more convinced that the 481hp is purposefully understated.
The tuned with header cars still amaze me that such a gain in power is so easily accessible.
It was interesting to see how close the MHP header cars ran in terms of 1/4 mph trap, although superlubricity was the most consistent out of us. However, both avenger and super seemed to edge me out on avg by 2 mph in the 1/8 mph trap. So it would seem that they are both making a bit more power than me, as shown when we dynoed together. However, towards the end of the run where I seem to close the gap, maybe that is the result of the Carbonio airbox/filters breathing better as speed increases?
Oh, should also mention super would probably have seen higher traps that day if he were running street tires, so I guess that explains some of it

1. Is the 2 MPH and corresponding horsepower increase by their cars simply the difference between catted and catless?
2. Are the multispoke OEM 19"s (beautiful, BTW) wheel/tire combo heavier than the OEM 18s?

Also, you guys trap awesome 1/2 track mph (94+) i cant get my head around why you guys can and we in aus dont (me personally and time slips ive seen) for reference on my 12.0 @ 121mph pass my half track was 92mph.
Did you guys try in manual mode? I seem to lose a tenth and 2-3mph in manual.
How were you guys launching? Any tips?
Looks like you guys had an awesome day. Lots of info being shared, thank you.
Here are a couple of quick snaps from yesterday. Wish I would have arrived earlier to catch more!

No videos, but here is the data from the two nearly identical back-to-back heads-up races between B.E.R.U.A.N.G (Eurocharged Tune) and cek (Stock P31 Tune).
RACE 1
2.392 60', 13.004 @ 114.83 MPH (1/8th 8.688 @ 90.42 MPH) <- B.E.R.U.A.N.G
2.413 60', 13.010 @ 114.56 MPH (1/8th 8.688 @ 90.48 MPH) <- cek
RACE 2
2.512 60', 13.330 @ 114.14 MPH (1/8th 8.981 @ 89.41 MPH) <- B.E.R.U.A.N.G
2.510 60', 13.387 @ 114.14 MPH (1/8th 9.039 @ 89.33 MPH) <- cek
This was before B.E.R.U.A.N.G discovered traction.
I'm glad you guys all had such a great time. Very interesting lessons from your guys' most recent experience.
The P31 and Eurocharged cars times are nearly identical. That's crazy. Obviously, the Eurocharged tune is an excellent alternative to the P31 car.
Btw, were the majority of the C63's fitted with stock or aftermarket LSD's?
