Looking for tips on the dragstrip

DuMa M3 · 08-15-2019, 12:39 AM

I recently went to the track. I managed to get 11.0 sec @ 128mph time slip. I would like to know at 129mph capable of a 10 second run. I attached a photo of my timeslip. Mods is just catless dp and E85 tune on BM3. I was shifting at redline . Any tips to go faster ? really would like to get into the 10s if possible.

Not sure why my picture didn't work. But here my time slips.

60'= 1.742 1.773 1.688
330= 4.767 4.915 4.765
1/8= 7.190 7.401 7.243
mph= 101.74 100.02 100.30
1000'= 9.270 9.506 9.334
1/4= 11.027 11.275 11.104
mph= 128.66 127.82 127.62

Outside of driver improvement, get better tires?

Power peaks at 6000rpm and the turbos run out of steam at 6500rpm, try shifting there.

I don't think you should be shifting at redline beyond the first two gears.

Have you ever dyno'd the E85 BM3 tune to see where the peak power is?

I'm on a stock tune and although I don't drag race the car, my shift point is around 7100 rpm on 3rd +

No have not had it on a dyno. Had a conversation with my tuner the other day and he also said to shift at 6500rpm. Im going to try that next time.

I cracked an 11.1 with VRSF downpipes and 93octane stage 2+ catless tune. Tires are a must, I went with the toyo r888r.

As mentioned it's all In your shift points and sticky tires. Stock turbos run out of steam at 6k and start to drop badly after 6500. Based on the torque curve ideal
Shift points 6k-6,500k rpm tops.

Play with Launch control rpms let the car shift to 2nd automatically. You want to be between 4-6k rpms or 4500-6500 max

Report back with a deep 10 sec run!! GL!! 👍🏻
