Usually the speed limiter only lets me get to 181 mph.

Data taken with a qstarz extreme (10 hz) GPS.

Nice … ! :sunglasses:

Just say it had an extra 200lbs in it, what would that equivalent value likely be … ? :wink:

WD :like:

Edit : Just thinking out loud, if there was a potential problem with the stability, could it also effect the electronic limiter ?

Wow, that's a good question. I wasn't sure if I was going to post the stability control issue, but most who run at Daytona know that it frequently checks out from time to time. It was most prevalent in the 350. The 350R happened less frequently, and the 500 CFTP hardly at all. In this example, the nannies were out to lunch.

I wonder if the combination of steering angle, speed and G coupled with the banked track puts the sensor parameters outside of the programmed limits ?

I guess it’s quite an extreme outlier and possibly not considered ‘normal operation’ when FP set the original parameters.

I talked with Dean Martin about this and he said that Billy would be the guy to answer that question.

Under normal circumstances, the speed limiter will stop you dead at 181 mph (fuel cutout kicks in). Either way, its about this time its time to get on the brakes for turn 1 of the Rolex course. As you witnessed, there isn't a whole lot of extra time from when you are in the 180 mph range to where you are hard on the brakes to make the turn into the inside course.

Again, normally you are limited at 181 via the speed limiter. I've never seen anything higher. Keep in mind that what you are seeing is a GPS speed with a highly accurate GPS. What the car thinks it was doing vs what the car really was doing could be the difference.

You are aware of the right front tire fiasco and how I had to grab a K2 spec tire on a spare CF wheel and deal with the resulting performance decrease. The time you see is 1 second off my usual 2 minute lap time at Daytona.

Just curious if you were running stock tire sizes and what psi you were running. Could that impact the computer's calculated speed versus actual speed?

stock tire sizes and the usual air pressures.

Very nice. That's moving.

I know this topic has been discussed by you and I before, but I would like to know what the car's non-governed top speed is just for gee-whiz knowledge. Can it go over 190, 195? With the massive front opening, I would be surprised if it could hit 200.
I know, it's governed for a reason, and if they wanted it to go faster, they would blah, blah, blah.
For curiosity's sake, I would like to know.

Obliviously it can do 185.4!

If given enough real estate, I think it would do over 200. I was told by someone in the know that one of the limiting factors was the half shafts. A friend blew his second set this weekend.

You bring up a good question, what can the car do? Once the Dct changes gears into 7th, it starts to pull again. I can't venture a guess, but 210?

I think this was my first run out. I haven't gone through and prepared any more videos because I'm swamped.

Please DONT like and subscribe. I hate youtubers and this is for pure entertainment value because this forum has been so boring lately.

Maybe ill get off my ass and put together something more interesting some other time.

I no reason to doubt your guess. You are likely one of the few outside of the Ford team or FP guys that has run the car to its limited speed in a fairly regular basis if I had to guess.
210 would be something.
