Would you see a difference in performance in an automatic?

[shecks7]

headers and a exaust is a great start, ESS supercharge it with Dinan software and it being a automatic or not, it will make a difference. She'll make you proud and will throw you back in the seat compared to a civic manual, its well worth it man.

az3579, I can usually get a nice judder-free 2nd gear. But I'm talking about getting some wheel spin. I don't see why anyone rev-matches upshifts..

My brother has a Steptronic 335xi and he now has 400+ whp. The JB4/Meth made the biggest impact.

A judder free 2nd-gear shift is a rev-matched upshift. That's why.
All it is, is waiting for the revs to drop where they belong to dump the clutch. There isn't as much to rev-matching an upshift (waiting for revs to fall to dump clutch) than to rev-matching a downshift (by blipping the throttle while downshifting with clutch in). They're the same thing.

I know what rev-matching is! lol

So why'd you ask why anyone bothers rev-matching upshifts? lol
I figured the answer would be obvious... for judder-free shifts...

lol it was just me saying i'm not sure why people do it. not how people do it.

My original question was if anyone can get wheelspin from 1st into 2nd (because i barely can...just a peep)

Sure, well I dont in our auto, but its not hard in nearly any newer car with 200+ hp. Now the bigger question, is why would you want to get wheelspin? Are you asking as in "barking 2nd" like 16yr olds leaving school? No reason to try unless you are trying to show off to people that are easily impressed. It only shows poor shifting technique and it's abusive to the drivetrain because you are simply trying to abruptly apply torque to over come the available traction of the wheels.

I've spun all 4 wheels in 2nd, 3rd and bit of 4th but that was in a highly modified 997 Turbo and I was actually trying NOT to spin the wheels on the way to a high 11 quarter mile.

I'm curious.

This is my first BMW and I have a Steptronic. I personally love driving my auto ZHP but my question is for those of you that have driven both manual and auto ZHP's can you tell or feel a huge difference?

[johnrando]

I thought there would be a huge difference, and by no means is this scientific as I didn't get to drive it hard: but I've only driven STEP and when I did have a chance to take a manual around the block recently, it didn't seem all that different to me. The manual driver said the same when he drove my STEP.
