I was not expecting that outcome at all. But the Pin Flare pulled out a win.

The AT is so much slower because of the double overdrive (5th/6th gears), and some slight tuning differences in the top end. The manual has only one overdrive gear. However, they both have the same 4.10 gears stock.

Once someone comes out with a set of 4.5X gears for the auto and some valvebody/torque converter options...then it should be more even.

That all depends on the transmission and driving style. A lot of drag racers prefer an auto Trans because it can shift faster than a human can. A manual is better for smaller motors on tighter courses to keep the rpm high and carry speed

I love the AT in this car, only other good AT under 30K range that can compete with it is the VW GTI AT (Wish we had a throttle blip when we downshifted). After that, dare i say it can compete with more luxury/sportier automatics at around 50K.

Don't know if you noticed but the AT is our cars rev match on downshifts.

Are you in the red car?

I thought the AT and MT were almost the same....its when you drop the clutch in the MT is were you see a 0 to 60 diff.

I know he's not running e85 yet...bc he has the unichip.

The Cusco 4.55 RCE is testing is good for either trans. Diff is the same.

This is on a tangent, but have any of you guys noticed that when do a sharp turn or u-turn at very low or slow speeds the diff/LSD makes some noise and feel a bit rough? Or is it just me or my car?

I'm sure it's just the dif working.. My dads dodge truck with some sort of LSD would have the tires squalling and chirping and then finally start skipping when in a low speed u turn because under power his locked the diff..

I'd assume with ours it's trying to prevent one wheel from "slipping" because one wheel is turning a lot more then the other.. Isn't that how our diffs work.. Lock up or activate when one wheel spins faster then the other

You're correct in how a diff works, but I'm referring to what's called binding. Sorry, I should have clarified.

I've noticed that the diff seems to show signs, via sound and feel, of binding when I'm at low speeds and do a sharp turn or a u-turn.
