All 55k AMG's. What trap speed are you hitting @ 1/2 mile roll events?

A good reference is add 30 to your best 1/4 mile mph and that is your 1/2 mi mph
NA cars are 28-30, under 1000 rear wheel hp FI are 30-32, and above 1000hp it varies 30-40-50 depending actual vehicle

It used to be the norm and generally accepted rule to post a vbox with any platform "record". However, all that went away once people just dealt with the fact it never read the same. Ive started quite a few fights on other forums asking for a vbox log of "World Records" and its always an excuse- vbox card didnt capture it, or it was "independently verified" etc. As far as I know, only Slipstream has actually been able to get the 2 readings to match to .25-.35 for runs.

it was an educated guess I used for years before we actually knew for sure; once we bought the equipment to actually measure it all in 1 run, it validated it:
Here's the list of time from SlipStream Invitational Private Event:

That's correct marine when guys say that the vbox recorded this or that speed etc, I always would want to see the verified file from vbx

if your car suffers from heatsoak easily, it may be affected more so than others, but yeah that would be about right from other cars we had run. We'll know a lot more after July as its a bigger day and a more diverse line-up, but should be the accepted norm- just like .1 in the 60' is .2 in the 1/4. Its ricer math, but it works the same

Makes sense. Guys reading this thread can use it as a guide..
Not much heat soak. I wont run back to back because of that. The car has always been stock since I purchased almost a decade ago. But, I still ice down and keep IATs cool as possible to get the most out of my car.
I usually ice down and now I take a garden sprayer filled with ice water and mist down my supercharger and heat exchanger before and after some spirited roll runs with my friends. Ya, Im kinda nuts about this.
But, wow anything above 140-145 mph is impressive for a stock car.

If you REALLY want to get performance, grab a 20lb bottle of nitrous and freeze your coolers before going ;0
