Is it possible for a AT 335i to rev pass the 7k rpm limit? - BMW 3-Series (E90 E92) Forum

KyLu II · 11-20-2012, 11:27 PM

Just wondering is it possible for a AT car to go pass the 7k rpm maximum?

AK 335i · 11-20-2012, 11:29 PM

if the tranny slips all things are possible

Eric335 · 11-20-2012, 11:31 PM

Im pretty sure that the tranny wont allow paddle-shifter downshifts that will put it outside the red-line. Although, i wouldnt go and test that, if possible

OP, do you think you over-revved the engine?

EDIT: Are you concerned about over-revving or are you looking for an increased redline?

it can and will, waiting on programing.

Well, that could be dangerous.

sono0b · 11-21-2012, 12:22 AM

i hit 7.2k the other day in 3rd gear LOL

VNeBLOB42 · 11-21-2012, 12:26 AM

I hit 7.2 from a manual down shift to first while roasting the tires and second gear went to 7.2 as well. Happened so fast my manual shift was to late. COBB pro tuned.

I believe COBB raises the rev. limiter to 7.2 for manual trans. I am not sure if that's the same for AT. it may be though.

But either way, my dyno charts as well as others, clearly shows the loss of power after 5.5k - 6k. I shift around 6k anyway.

Same here, around 6000 which means i actually shift around 6250 due to my reaction times.
