Launching A-10 w/1st gear delete
This build hits the strip on the 20th down in Nebraska, so we'll see how much the higher DA helps.
My question is, how best to burn out with the MT ET Street R 325/50R15. My default would be to burn out in 2nd and roll out, but I'm wondering about shifting to 3rd just after the tires start spinning. It should get a lot more wheel in 3rd.

Yep... start in 2nd and shift to 3rd.

I drew the same conclusion because it doesn't have enough wheel speed in 2nd

I know you've had traction issues in the past. Are you planning a 3rd gear leave option if it's a problem again?

Definitely not. My 9.28 was launching in 1st gear with a 10 spd. I’ve used 2nd and 3rd gear launches on no prep/back of the track. I’ve exhausted that and moving to 2nd gear launch on front side now.

I race in manual mode with a tune that deletes first gear. It's inconceivable to me that I could get this car to make a decent launch in first gear. On the other hand, I believe Brian at dinosaur juice told me he has a number of clients launching in first gear with an A10. This would indicate that you can reduce torque somehow to get the car to bite

Thats impressive! Mine blows the tires off bigtime even with decent track prep! I put a 15 inch conversion on over the winter so I may try a 1st gear launch..

FWIW the midrange timing cut paid much bigger dividends than the 15” drag pack did…

Gotcha... Never played around with pulling timing on this thing. When this car ran a 9.37 the 60 foot was a lazy 1.49! Hoping to get that 60 ft down to low 1.40's high 1.30's. That should put it close to a 9.0X Gonna find out this Sunday @ Cecil
