Yeah, Im gonna say mine is around 7200. Ill test it on my way home, if the roads dry up.

Yeah, seems high. I wouldn't want my car to rev higher than stock redline--7200 rpm... just sayin.

Happy to report that tonight I ran a 12.39 @ 114 at etown...that's with a crap 2.09 60'.

My best previous stock time was 12.77@113.

Even on street tires I know I can shave a couple tenths off my 60'...with DRs I believe this car will run 11's.

On iPhone now...will post timeslip manana.

While your results are respectable, I'm a bit surprised you didn't gain more on the trap speed. If the v3 tune is truly producing 60+whp over stock, you should definitely be picking up more than 1mph. I'm also guessing the DA conditions were better tonight compared to your stock runs, so once adjusted, you may not have picked up anything. Not trying to be critical, just making some observations.

Regardless, good job getting out to the track and putting down some numbers.

I agree that my trap should increase more - I believe (hope) that it can I just need more track time to learn how to launch properly.

More testing required and I'll be sure to share when I do.

Launching better will really only help your ET. Your trap speeds are likely valid. You could have a terrible 60', yet still have the trap speed you should expect.

xtyper

Agreed, and that was exactly my concern. Although more practice will likely improve the ETs a bit, the trap speed shouldn't change much. To me a tuned car should be trapping better than 114mph in decent conditions.

FWIW, I ran my car in S mode. When stock, I alternated runs btwn S and M mode and experienced traps that were about 2MPH faster. What i discovered was S mode = better ETs/lower traps and M mode = higher traps and lower ETs...This was consistent
across every run...any thoughts on why?

Jon's C63 stock was trapping 115 on stock tires. His best trap with an OE tune was 119 on street tires. This is why I say track times show the big picture. 113 is quite low for a 540 HP car. Hopefully we can meet up BK or you come to a track event soon with some DR's. Ill help you get that car dialed in.

I was trapping btwn 111-113 when stock. I'm really want to see if I can pull higher traps because it is a little disappointing to think that the tune hasn't given me the increased performance that I expected.

I'm going back to the track tomorrow to see if my traps improve...if they don't then, I guess I'll know where I stand :-/...fingers crossed.

BK63amg

I appreciate that - please keep me posted in the next track day!

Sounds good. Come chill at the Bimmerstock show next Sunday.

BK63 i was the one you met at wawa!! haha small world.. your car looked sick i got to the strip late.

I agree 113-114mph is STOCK trap speeds. That's what I used to run stock.

Since having put in Renntech stage 2, my trap speed increased to 119mph which is a high 11 second trap.


Also, after putting in the tune, I could spank the M5, which I could never do stock.

Trap speed = king.
