Car and Driver tests GT500. Runs 11.4@132...

Ive seen this at the strip. Spring air runs faster than summer air. If you put drag radials on in the summer, you’ll still be quicker, but temps are higher and power is slightly lower.
I’ve been to the track as well. My experience is when I can go wot sooner and launch better my trap speed is higher.
I realize from seeing you try to extol the forum of your greatness on other threads that you believe the world is poplulated entirely by idiots (with the exception of yourself) but....contrary to what you may believe, I am perfectly aware of the wide variations in vehicle performance due to atmospheric conditions.....
I’m not comparing winter runs on OEM tires to summer runs on drag radials. I’m talking runs in very similar conditions.
But that’s OK. You continue to believe what you tell yourself. All I know is I pity the first unsuspecting GT500 owner that really thinks a Redeye is slower by almost 3 seconds to 150 and tries one from a highway roll.
Mine does 0-130 in right around 10.5 seconds. You really think it takes another 4.5 to pick up 20 more mph.

I don't have a dog in this fight but from my track experience I can say my car often runs a slower mph with a quicker et. Never really understood it but it has happened many times.
Oh man surely if you’ve read through some of the comments above you realize there’s no place for that kind of common sense and actual experience here.

I’m just a loud mouth by nature, it has nothing to do with this forum exclusively, you give me too much credit. You must hate my politics, god bless you, and Merry Christmas. On a 60mph+ freeway roll, a red eye charger should mob. I’d probably bet on a stock redeye charger over a 2020 gt500 if both are stock power-wise from a 60 roll especially if it’s a gurney wing gt500 or the carbon fiber track pack. Lower drag coefficient and more torque of the redeye Charger is excellent for freeway rolls.. Then again, if gt500’s are really putting down 700whp then it should win regardless in base (non gurney or cftp) form.
I think a good 3-4 second is needed for your red eye to go from 130 to 150, yes. Time it and let us know. My personal experience is I can easily hit 130-140 on an on ramp, but burying my speedometer to 160 takes maybe 3 times that amount of distance/time. I have a hard time to hop on, bury the speedo, and hop off the freeway if it’s under 10 blocks. I think an average onramp is about 1-2 blocks. I have 800whp on pump gas and .35~ drag coefficient. I’m not certain my car can go 130-150 in much under 3 seconds and itll trap 140-145mph on that’s setup.
There’s only so much time to cover distance in a race. If you spend fractionally more time, you are likely to be fractionally slower assuming perfect traction. That said, tires unwind once spun a little too much and that does translate to forward motivation. Do a rolling burnout at 40 and then let off the gas. Rubber band effect will push you clear past 50mph. I saw it on need for speed, promise.
If you have wheels that are spinning just a little off the line, when they unwind, it can bolster acceleration but be a slower run over all. If you chirp/spin slightly through a gear change like 1-2, 2-3 etc it can give a little boost too as the wheels translate the excess motivation and eventually return to match vehicle speed again. This is a big reason why a power shifted car can trap 2-3 mph faster than a very very quickly speed shifted car.
If you spin em to 330’ though, then yer run will be crap because you wasted 1/4th of the run doing a John force. You struggle to trap with 10mph of a proper run.
Dodge hellcats and red eyes spin stock pirelli tires to 330’ pretty easy and need to be heavily pedaled. That’s why they pick up so much trap speed with just a tire. Very torquey power delivery. The gt500 is much less torquey so it simply won’t get much any of that. It might honestly just bog a bit unless a tune can raise the launch control rpm.

You do realize this is not on a prepped track? You are comparing your times on a prepped track to ones that aren't.
Did you take into consideration the tire tech on the GT500?
Launching using the DCT?
Shift times?
These all play into the times on the street. To assume your MPH is the same on a track as on the street seem to dispute your 'common sense' scenario.
There was a big thread on this about 12 years ago and everyone said trap speed goes down when you add sticky tires.
Then Ranger who knows how to launch and drive a car ran 3 mph faster in his new c6z with drag radials. That ended the thread real quick.
Most driver will trap lower on sticky tires. Too drivers will add trap speed as the horsepower in the vehicle is used to hook and not spin.
Burry=buried I think. Just a translation.
LOL
I got "Blurry" out of that.
Hennessy is crap. Always will be!
the c6z was faster to 150 than the c7z. Part of the reason the c7z ring time was below expectations.

I logged on to fix typos... and then I realized it’s not even legible... I need some time to sort it all out.
I see 26 seconds to 30 seconds 130-150mph. That’s 3.5-4 seconds.
The demon is obviously faster than the redeye so the average red eye is probably 4-4.5 seconds 130-150mph, @Sirhc7897
@Sirhc7897
He goes from 1.51 to 1.49 to 1.47 60 ft and he goes from 127.x to 128.1 to 128.5mph almost as if by some miracle of miracles, reaching 60ft a fraction sooner a fraction more optimally sets up the car to trap speed a fraction quicker and faster.
Best way to think of that is if you take a car and accelerate 1260ft wide open throttle with two tests, one from 29mph and the other from 30mph, and are able to hookup equally optimally on both runs, the vehicle starting at 30mph will likely be traveling more than 1mph faster than the car that started at 29mph.
On traction limited cars, this is very evident. Fwd cars literally drop 1-2 seconds and trap 10-20mph high on drag radials and slicks all season or decent summer tires. A tiny bit of spin on power shifts can bolster mph and reduce elapsed time, but much more than that ends up hurting elapsed time and very soon thereafter begins hurting trap speed. It’s not video games or whatever you insinuate I’m trying to sell a room of people on the Internet, it’s common sense.
Here’s an awd skyline that picks up 4mph in the 1/4 mile. Just street tires swapped for drag radials. He even spins quite a bit launching much higher rpm.
Cheers.

Dude....I totally understand what you’re saying.
But you’ve also claimed a drag radial is magically going to give a car 3-5mph trap speed increases.
It’s not your claims or science I doubt. It’s the exaggerated nature of the claim I doubt. Especially since I’ve put a drag radials on one of the cars we’re discussing and personally seen no (or at best marginal) trap speed increases despite improved 60’s by close to half a second....in the same DA....at the same track.....in the same lane.
Oh and that demon is on the 808 tune so it’s basically a widebody Redeye at that point with worse drag characteristics.
Make it a standard body and add your 4 second 130-150 to a 10.5 to 11 second 0-130....that 17.7 time is pure crap.
*except maybe on the all season Pirellis. I’ll readily admit that.

Knock it off with all of that common sense wrapped up into an easy to read, to the point post!
It’s the return of thePill.
