Transgo Valve Body Upgrade and Exedy Technics Sports Clutch Kit with the steel mating plates.

Made a world of difference in my 5AT

 

Ya, I'm boosted peak torque at around 3500 (5psi spring), but even with that I'm only 8mph more than op.
I wouldn't worry about trap speed. Worry about ET and 60'

Side note. Did you ever go to the track before you lowered the gears? If not, seems silly that you would change them without knowing what iit did previously.

 

Yes and the swap of gears dropped my time by 0.2

 

This. I was running that quick/faster with just a plenum spacer and intake.

 

There are a lot of folks out there that don't really understand the relationship between ET, trap speed and traction off the line. My full bolt-on '06 stick would run low 14's @ 105 if I spun off the line and 13.7 @ 99 if I hooked. I low ET with a low mph just means you're launching hard with little wheelspin. What matters is your ET, not your mph. BTW, this is in Vegas with a 7k foot DA and zero track prep. Just to give you an idea how horrible our track is, I had the quickest NA Z in Vegas until the 370 came out.

 

My roadster doing 141 mph trap speed and I think it is (s)low.

 

wanna feel like a loser:
wanna feel like a winner:
477hp/467tq, high 11s low 12s @ 117mph (at altitude) … one more reason NOT to move to Colorado
