First track passes in the 15

[Major League Infidel]

Took her to the track last night and squeezed off a couple of runs. Only mods are the FRPP Sport catback and Steeda springs. both passes were 13.2@107 and 108 respectively. no tire pressure changes or anything. launch control set at 3k and 3100. might have been able to go a little higher with it since it felt like it bogged a little.

What was the 60'?

2.1s

MPH looks low; were you shifting into 5th before the traps or lifting early?
Do you know the DA for that day?
Maybe try quickly leaving off idle rather than launch control on stock tire? My bone stock 14 GT auto ran a 12.8@ 113 and 2.2 60ft on second run ever. 1st run was a 13.6@ 113 mph and 2.7 60 ft. I doubt the 15' GT is that much slower.

1300 da and hitting 5th

1300 da and hitting 5th

Yeah my runs were in a little better air. You should defintely leave off idle modulating until traction is achieved, shift quickly at 6800 and wind 4th all the out through the traps. You should be hitting at least 110.

I hit limiter with the 3.73s before the traps. i just checked the DA of the first run was 1687, according to the correction at sea level it wouldve trapped 110. since Im doing the ole ricer math with the weight and trap it should be making around 394 to the tires which is ballpark for these cars stock. I think it wouldve ET'd better if the 1-2 wheel hop didnt cause me to partially lift too.

I hear you and not bad in that regard using your theoretical ''ricer math'' This is why I feel 3.55's are more optimal for the 1/4 on street tires, can ride through the traps in 4th and easier off the line; however, 3.73's on taller slick should take it.

Decent. Work on that 60 ft.

 

[Major League Infidel]

If I dropped tire pressure I could've gotten the 60ft better. I literally teched in and made passes. Once I go FI I will prob drop to 3.31s
