1/4 mile 4100 pound 21 vert, runing Roush 2650

Very respectable for a Roush.

Could do a lot better with some long tube headers, on E85 with a custom tune. for stock exhaust, on a Roush tune, running 93 octane pump gas. I agree very respectable

That’s for hard tops. Not convertibles...

“Convertibles quicker than 13.49(8.25) and T-tops quicker than 11.49 (7.35) must meet Summit Racing Series roll-bar and roll-cage requirements.”

Perfect, thanks.

Pretty impressive for a heavy vert. Do you happen to know what the DA was on that run? Any plans to turn it up more?

 

[Coyote Chase]

What RPM and which gear do you launch from?

No sorry I don't know what the DA was that day, no plans to turn it up either right now. sticking with the stock Roush tune till the warranties up. it's just a weekend fun car, and for a convertible man the thing runs great a 10.50s convertible that's plenty for me

It's a 10-speed automatic I just stall it up to about 2,000 RPM after burnout comes off the line hard run it down the track in drag mode shifts great

FYI: What I've learned about the 10 speed transmission, is that I can launch in 1st gear at around 1750 rpm and let the car shift itself or I can launch in 2nd gear at around 2500 rpm and shift manually.
Oddly enough... My 1st gear launch, puts me in (low RPMs) 7th gear, going through the traps and my 2nd gear launch, puts me in the high rpm range of 6th gear.
My ETs are similar!?? But, I'm still in the early transmission tuning stages.

Still learning as to what all this 10R80 transmission is able to do?

Thanks

Was this car owned by Brennspeed? I ask because they had one on their you tube channel that looked just like this running similar times.
