Took my Cobra to the Dragway, on street tires :(

Wanted to basically see what the Cobra would trap on Corn.

I knew going in that on my street setup, R888 all around, than any ET under 11.5 was going to be near impossible on a street night with little prep. I was shooting for 135+ and I hit it

I really don't want to cage the car. So no point in big and littles since my track is very strict.


Ran a best of 11.54 @ 137.25

Nice mph!!! Tires were probably begging for mercy on that second pass.

Holy! That’s moving out without really trying!

That's moving out for being on street tires. You have a 10.9 pass with a drag radial out back.

At 137, he has a lot more than a 10.9 in it. Lol

Good stuff OP!

Wow, that was a really impressive run on street tires. I want a ride! LOL.

35mph back half is the most impressive part. Your car is making some power!

Nice!

That back half is awesome! Congrats!

I'd like to think 10.3-10.5 if I could dump at 3500 and dead hook.

IDK how many mph dead hooking is worth and being able to be WOT the full 1320 feet

That is what I noticed, tire finally started to grip and the Mules HP took over. Tires were probably spinning a portion of the 1/8 & didnt notice.

Pretty damn nice... with some drag wheels and slicks, you might he knocking on 10.0's with a dead hook launch.

It wont back half that kind of MPH with a good launch and drag set up.

Not at all taking away from this car's performances.. its a beast... High 9 sec car considering 137 mph.

But the 35mph back half is a little misleading considering the front half on that pass.

I had varied back half results...

29.9 to 35.5 gains

Trap was around the same, but my 1/8 mph was changing a lot dependent on how soft the launch was.

I'd have to look at my slips

Here are my other 4 passes.

Gains of 35.23, 33.09, 30.51, 29.82 and then finally 34.31 on my best pass.

My final trap speed varied from 130.73 to 137.25 with 1/8th mile traps larger at 95.05 to 105.92.

It's not by chance my slowest 1/8 resulted in my fastest top end gain, while my fastest 1/8th in my slowest gain.


So maybe if I dead hook and boogie, it would continue to drop

Agree....

Looks fun!

Also I calculated the DA. Was around -400 to -600 for my runs. The humidity was getting up there and was resulting in a lot of dew forming everywhere.

Probably resulted in a slick track

That thing is moving out on the big end

that is definitely moving on the big end! I just ran 139mph on wastegate but since i had a 1.4 60'...that resulted in a 9.75. So thats a 9 second mph right there!

Thanks man

I semi debate racing it more often. I just don't have the passion I did earlier.

Seems to just break the car, or past cars haha

Also really don't want to invest in cage/harness and everything else needed.

But the idea of running 9.999 is damn tempting!
