Ran a personal best Saturday at ubly

1.63 60 ft 10.8756 et 129.14 mph. With this mph, I feel my et should be better and I know my tune is set a little more rich than lean- could this be why? What are your thoughts.

Mods Procharger 7lbs Boost slicks.

Nice 60ft time, trap speed and et. Does your time slip break down you the times more?

2012 SRT automatic, PB 12.0490 with MT drag radials and trinity 93 octane tune.

Labor Day 2018, maguson supercharger 5.5psi, forged piston/rods, Hellcat injectors, 10/1 compression, tuned for 90 octane. [email protected] with lots of room for improvement.

Great time! I assume that you have a 392 engine? What other mods do you have besides the Procharger and slicks?

trapping 129 mph in a full weight Challenger requires around 690 whp . clearly you're not making that kind of HP with a 7 PSI Procharger.. what is the rest of the story ?

I don't like going by dyno numbers and clearly depending on the dyno you don't need 690whp to run 129.

Case in point, my '13 Mustang dynoed at 590 whp and at a race weight of 4,000# ran [email protected] So the 4mph more should about offset the extra weight of the Challenger so I would think closer to 600whp on the same dyno.
