Cool, thanks for the help guys.
Roll racing gives you the best idea of how fast the car is day to day IME. 0-60 times and even quarter mile (to a much smaller extent) are a matter of turning the engine into a flywheel and dumping the clutch. If it's something with AWD, the effect is magnified, you can just launch it and let all 4 wheels grip your way to a fast 0-30 and 0-60 time. This is how subaru used to advertise their cars, it was literally written "don't look at (competitors) HP, look at the acceleration times!". They were down on power and their actual WHP was fairly low, but you could zing them to 60mph pretty fast with these techniques and the help of some short gears. But race from a roll and they fell flat on their face. Especially with older turbo cars that had to rev pretty high to make any serious torque. Almost any car can launch strong to 30mph, but if you are cruising at 60mph and floor the accelerator...then what happens? The roll figures give you a much better idea of what this will do.

From 8th gear not a lot. But drop to 5th and hit it and you'll be up to 135 pronto.
I can't believe I wrote this. I sounded like such a newb..lol.
Thankfully I learned how to actually roll race the thing beyond just punching it. Using the paddles to downshift definitely helped but learning how to properly brake boost it was a game changer. Brake boosting from 45 in second gear (or from 60 in 3rd) makes a HUGE difference, if done right. Not good for the drivetrain obviously but it seems to be able to handle it *knock on wood*

Not obviously to me. How are high revs and punching it "not good" for the drivetrain? It's what the car is designed to do. There is no way that a stock engine can be over-revved. The car won't let it happen, in the first place. And even if we could hold red line, it wouldn't do anything, since the tolerances of this engine are tested for literally continuous DAYS at peak revs (stopping only to replenish the oil). As for the transmission: it is up to a lot more stress than the stock engine will put on it.

I think I'm dumb because I've been struggling to get the car to let me brake boost. I know on some modern cars it won't let you hold the throttle and brake like that but obviously if others have done it then it works. Any ideas what I'm doing wrong?
Nah you're not dumb, it takes practice to master it, since the ECU doesn't like it. The main thing is to go light; if you give it too much brake and throttle, and for too long, power is cut.
Lightly touch the brakes (I use the edge of the pedal so I know I'm not applying too much pressure) and start applying throttle gently. I see you have Injens too; you'll hear them sucking air, that's how you'll know it's working. Hold it for 3 or 4 seconds, which will be enough to build a few lbs of boost. Release the brake and nail the throttle at the same time and you're off.
If you do it right, it makes a huge difference.

And your competition will cooperate so that those three-four seconds of boost-building happen right before you GO? How do you time this?

Thanks that's really helpful.

It's a roll race so your competition doesn't have to. The trick is you're maintaining the roll speed but also building boost so when you go it will launch harder.

This would work if you're using a track and a marker. But a rolling start "in Mexico" would be problematic, to time the brake within a three second window and with the other guy. Is there some trick to that?

No idea how you make that work, just luck I guess. I was on a track so we had a designated roll area and a hammer down area.

I've got the bug now. Got beat by a few guys I need to get revenge on. Got beat by some no amount of money put into my Stinger is going to rectify.

Were you able to beat some other cars that made you feel good?

I beat some sort of modded Mustang, I missed what the guy said so I never figured out exactly what had been done to it but it wasn't a 5.0
A convertible Camaro SS twice
A modded Focus ST
A BMW 335i
A seriously modified Infiniti Q35
I know I beat a few more but I can't remember off the top of my head what they were. There was a Civic Type R there I really wanted to go with but he left before I got the chance. None of them were really walk overs for me so they were all fun. Lots of people wanted to know about the Stinger too, including a track worker who sought me out at the drivers meeting and told me he'd been "waiting for one of these" to show up.
