Help with launching the car
Hey all. I took my 335 to the track today for the first time and I feel like I did fairly well. However, I think the car has more in it I just can't get out of the hole good enough. I was trying to launch in 2nd with traction control off at about 1500rpm. It seemed like it wanted to shift in to 1st every time. The one time it didn't the results weren't really better. I've attached the best time slip I got. Every run was pretty much within .1 in the 60' and ET. MPH was 112 for every run except this one. It was the 12.8 @ 111 if you couldn't guess. If any one can help I'd appreciate it.
Any how here's the mod list.. VRSF 5" intercooler VRSF DP MHD with E40 map (running E40) Alpina transmission flash I'm running stock run flats and had 3/4 tank of gas. I have the MMP relocation inlets, I plan to install them this week or next week. For some reason the picture doesn't show up. The link is View post on imgur.com |

Put it in 2nd, hold break with left foot, hit desired rmp (I launch at 1800). let go of break and quickly ease into gas. dont put your foot through the floor and hit the kickdown.

Like the others are saying, sounds like you're hitting kick down, disable this in MHD.
A friend of mine (right?) was running the OTS E40 map on slicks and cut some 11.6x/11.7x runs so you have plenty of room to cut time. This same guy is the one who told me launch in first. He also now launches in 2nd since he has PS2's and should break 10's soon. My $0.02 and Im sure people will jump just shit on me here so take it with a grain of salt
Here is my sequence when I line up
I'm getting consistent 11.8x and 11.9x runs with 1.7x and 1.8x 60ft's on an all season tire (265/35/18). Make sure you're logging your runs. You could be heat soaked and not even realize it. I've had some REALLY bad runs, like a 13.0x run because of a little heat soak and a heavy foot. How are you 'measuring' your ethanol? Each station varies and if you dont have a tester kit or analyzer guessing or using a calculator may not be enough. Again, take what I say with a grain of salt. Try different things. You have to learn the way YOU drive and what makes YOU feel good about your runs.
