Pretty close to E60 M5 numbers! That's not bad at all.

That would mean the car actually has about 520hp. (all estimates of course) Not bad!

This slip helps prove my point and my guess of 12.0 seems to be quite accurate. This one slip is from a C7 Corvette - slightly better DA and 60'. The key is the trap speed everyone.

There were - it was a multiple competition track day. I actually beat a Mustang in one of the competitions and another Challenger as well. It will run a low 12.1 or 12.0 with the right conditions and it will be SUPER consistent. I ran 12.3 four times in a row lol.

I was there with my other car...it's not a drag car either.

Love it ! I have a 2017. 650hp pulls hard. Tip for ya. I had my front plate like yours. Then bought an undermount. Big plus for H20 temps. Plate covers 40% of the airflow per Tadge.

What did the Z run ?

Thanks - my car has the two side vents completely opened (no elbows in there anymore) - and the oil cooler and intercooler are also in the way - so I'm not saving much by removing the plate - that said - I'm sure it wouldn't hurt either.

I removed the stock SC as I was having massive heat soak and over heating. I replaced it with an F1A procharger (and cam for the extra fuel) setup and love it now. You have a 17 with the taller lid and bricks 7 and 8 angled - that is supposed to help with the heat soak issue.

PC's are tough to launch - especially with a manual - so my best ET is lacking: 10.0. My MPH is healthy at over 145 MPH however.

The car really shines in the 1/2 mile - where I ran a 178 best MPH (which I believe is a record for a manual C7Z with a F1A setup).

I have a car I drag - so this car is my GT car - I just needed a certain amount of power (145 MPH traps were my goal).
