It's a great track and those numbers are probably pretty accurate, I guessed about 2500. Yes I was very impressed and satisfied to get that 10.9 all stock everything!!

Temps in the low 70s. Still stuck in the 10.8 range but a little quicker. It launched so far it gave a "warning: damage to vehicle" warning on the center console as if it had been in a collision lol. 3.2s 0-60. AFR got in to the low 11s in 5th.

I found using launch control is more consistent but is actually a little slower. Without it I could cut 1.63/64 and run a 7.0x 1/8th but I also had to worry about the breaks pushing through and red lighting. I would guess Terry is trying to launch consistent and has a technique he sticks to.

LC is an easy 1.68 1.63 is impressive by foot brake boosting. Did you LC the 10.99 pass ?

I just brake boost it. Might be able to launch it a bit harder but I'm more or less launching it as hard as it will go. Never been able to engage launch control and doesn't seem I need to. I suspect it requires DTC fully disabled like it does on other models which I'd rather not do racing.

If you want to keep DTC activated, part throttle brake boosting is the best method. Do a couple of hard stops before making a run....helps the front pads clamp.

Timing wasn't that bad previously so I did not expect a ton out of the race gas. It might take more boost and cooler weather to get the traps up. It's definitely a heavy car though. When it cools down a bit we need to get all the new cars over to Famoso for some test and tune action!

I think realistically on a cool night 10.6@134mph on race gas and map3 tune only is a plausible goal. And for a basically stock car, would be pretty sweet.

Why don't we rent it out for one night a small group of OUR people only. Plus I can have my cousins drive up some BMS cars so we can actually test them all

Maybe when it cools down. But with dragy now it's so easy to get metrics, hardly worth the extra effort for a big drag day anymore IMHO.

Boost is driver side boost, and boost2 is passenger side boost.

You live near farmland so you have long stretches of roads. I don't have that luxury

The throttle body is over sized for flow and used to as a safety system for valvetronic which does the majority of the engine control. As mapped will move around from 50-100% depending on where boost is vs. boost target, and engine speed.

Is the left side JB4 scale that goes from 0 to 50 a double value to get to the “50-100%” range ? IE , if the “Throttle “ log is at 45% on the JB4 scale, multiply that by 2 for an actual 90% ?

It's saved as 0-100% in the CSV, and shown as bottom to top when looking at chart.

If Y scaling is set to 50 (default) then 30 is 60%.
