I am trapping as high as 116mph, and I cut low 1.6x 60fts, and I can still only get a 12.04. What am I doing wrong?

that don't make any sense with that 60' and the speed. I was running upper 11's at that speed on a 1.7x 60'. don't know what to tell ya there.

Post your time slip maybe some of us can see how your 330, 8th mile and 1000 ft. times compare to our 11 sec. slips......your good 60ft. and trap speed is more than enough I would say, somethings up.

1.63 60ft 1.68----think I spun a tad
4.946 330ft 4.99
7.693 1/8th 7.74
90.88 mph 91.06
12.04 et 12.07
114.2 mph 114.4

Here are two of them. I have one more where I trapped 116 with 1.63 60ft. I have several of them laying around here somewhere. These are pretty average. This is a 6spd car, and an 01 ws6 since my sig doesn't say it

Hmmm......the only thing I can see by looking at some of my many timeslips is that you might be loosing a little bit between your 60ft. and 330 compared to mine but I have an auto. Also my 8th mile et is a tiny bit quicker but your mph equals and betters mine on most passes.....I have run many 12.0 passes and a few high 11's but that was in really good air in nov. Your car has me easily covered in hp and should be in the 11's.....Maybe some m6 guys can chime in. And this time of year the air and the da is not that good. You will certainly be in the 11's in better air but I know that doesn't make you feel any better now.

Here are 3 of my slips that are close to yours to compare:

1.651 60ft 1.640 1.649
4.904 330ft 4.890 4.886
7.617 1/8th 7.604 7.589
89.94 mph 90.11 90.33
9.992 1000ft 9.970 9.946
12.00 et 11.97 11.94
112.24 mph 112.77 113.27


Hope this helps you a little.
Post your 1000ft. if its on your slip.

1000ft isnt on the slip. I would hate to say its my tuner, he does a lot of guys around here and their cars run fantastic, all deep in the 11's with their cam only setups. You guys think it could be my gears and tire combo? I need more practice for sure on the slicks and skinnies, I have only went out to the track on them two times. Maybe I cant drive? But if that was the case and I couldnt shift worth a damn wouldnt that show up in the mph?

I'm thinking this is the culprit. Your MPH shows the car has some power, and the 60' is pretty good for an M6 car, so this seems like the logical choice.

I wouldn't really say it was your driving although looking at your 60fts. vs. your 330s maybe your 1-2 or 2-3 shift is costing you a little et but I am no 6spd. guru. And 4.30s with a 28" tire sounds about right from what I have been told. Either way practicing and getting seat time you will improve on those ets, good luck, you have a nice car there!

You're losing it on the top end. The 114 in the slips you listed is gonna put you right where you are in the 12.0 range with a 7.6 1/8. Not impossible to hit an 11.9 as you're right there, but another mph up top would do it. With those 1/8 mile stats, it's a simple matter of power up top that you don't quite have. Like I said, definitely possible you'll do it in the future if you nail that launch and every shift, but based on the trap and 1/8 you're right where you should be for that trap speed.

Let me ask you this, on the 115-116 trap speed runs were your 60's also in the 1.6 range and how about your 1/8 numbers on those runs? A 7.6 1/8 with a 116 trap should do it if you don't screw up the shift.

But if I was shifting like **** wouldnt the mph be lacking as well? I would think if I shift really slow, I would have an even shittier mph

I am thinking I am leaving some on the table with the 1-2 shift myself. My car revs so quick with these gears the tach isnt even close. It will smack the limiter around like 5.5k if I remember, well before my shift point. Limiter is set at 6.5k btw. I have a harlan shift light sitting right here to install before the next runs. Thanks for the compliment

When you say the 114 puts me right where I am, is that because of the 1/8th mile time is slow? I am thinking its somewhere lower, my buddies trap 113-114mph and run as low as 11.6x's with a 6spd. The run where I trapped a 116 I actually only cut a 1.8 60ft. This was one of my first runs ever on the slicks and I didnt leave extremely hard. The time came in at a 12.40.



I appreciate all the help guys

The reason I asked it there are some calculators on line like this one that you input your RPM's, tire size, rearend ratio and final trans gear ration and it calculates the MPH.

At 5800 rpms you are at 112, 6000 rpms you are at 116

I run near you but best trap is 112 MPH with an A4. You should be 11's but somewhere you are losing it. Maybe spinning on gear change?
