Evolution Performance, Inc. "The clutch is officially Toasted, it lasted a lot longer then I thought! New one should be here tomorrow, but that one won't last long either! Upgraded clutches are going to be a must when running with sticky tires"

The other thing about the high MPH on the drag tires is the ET streets, it looks like they are probably 28" tall tires on there if not taller so that would help the MPH considerably.

Those numbers just do not make sense.
Very first run, last week, was a 13.2x@110mph on street tires, with a 2.10 sixty, in good air.
This week, a run on street tires nets 12.61@108mph with a 1.96 sixty, in presumably marginally worse air(this early in the day).
Then later on, on full rubber, the same car picks up 9mph? Nine?
That middle run does not compute with the other runs. Picking up a tenth in the sixty doesn't equal a full 6 tenths on the big end(today's street tire run vs first run), especially when losing 2mph through the traps. And this car is supposedly making 40hp/30tq than last week.
And then it picks up NINE mph by swapping tires? Anybody else confused by these numbers?

I was guessing 120 mph with full bolt-ons. CAI (Not avaialble yet), Tune, Long Tubes (Not yet available) and Full Off-Road Exhaust, Pulleys (Likely minimal gains with the new super-efficient water pump). Im thinking I might have been a little low.
120 mph trap is going to require close to 7300 rpm in 4th with 3.55 and stock rubber (Dont forget finish line mph will be close to 122 mph). I didnt think I wanted to spin it past 7500 rpm so thats the reason I didnt get 3.73. We got 1.79 out of a CAI/Tune/4.10 4.6L-3V on Stock Rubber and with the lower 1st and more torque I believe the 5.0 will do at least as well without gears. I know many dont buy it and thats okay. The proof will be in the doing or not doing... Until then its just Ricer Math...and Im bored (Railroad is holding my car hostage)
PS I wont be suprised if 11's on the 5.0 are almost as easy as 12's on the 4.6L-3V.

117 mph is good for mid 11's. it will take more time to get the full ET out of the power. once the coyote gets to 435rwhp with bolt ons like an LS-3 mid 11's should be pretty easy.
i still want a boss 302 intake manifold for mine.

No, the 9mph was from switching rubber, in comparison to the first run of the day on street tires. But as other people have pointed out, there were clutch problems and they were probably riding the limiter.

Well, if the ET streets are 28" tall, then the soft limit of 6850 makes for 116 mph, 118 at 7000 in 4th.
If they are 29" tall, they would be better off, would get them to 123 mph at 7000.

The Knock Sensors are very sensitive on the 2010 GT500, almost too sensitive that's why there has been four strategy changes from Ford for the Knock Sensors being to aggressive when hearing noises thinking it was knock even though it wasn't.
When we tune the 2010 GT500's on the dyno we turn the knock sensors off, tune the car with the necessary fuel, timing, DBW changes and then turn the knock sensors back on, but decrease the sensitivity. You maybe be running an old strategy with a higher sensitivity! You can read the strategy with your X3 to find out what it is!

From what I can tell the clutch blew AFTER the 12.04. At first I thought "wow" that's a great MPH. But you raised a good point earlier (as someone else did on another forum - a seasoned racer) ; the difference of 9mph doesn't make sense. Now that I think of it you can't just pick that much speed up with slicks. Maybe Fred can explain it when he gets on here.

on the run with stock tires they were hitting the limiter so they had to push the clutch in before they crossed the line so that is why the MPH on the first run yesterday was so low compared to their 111mph in previous stock tire runs.

Thanks for that, Todd.
So, just to get my head around this, this problem didn't occur with the strip tyres as the higher tyre didn't require the extra rpm just before the end of the quarter, and nothing to do with the clutch itself having a problem?
Cheers.
