  1. 5w-30 to 5w-50 on na 5.0

    Temperature. Pressure is measured with a sensor.
  2. 5w-30 to 5w-50 on na 5.0

    The only issue I can foresee, if it even is an issue, is that the inferred oil temperature displayed will no longer be accurate, but read artificially low. Probably not that big of a deal, since you already know what the temperature was before on track, and you have experience, so you are...
  3. 2026 NASCAR Trailer - Dark Horse Domination!

    Fun commercial That is Clint Eastwood's son. I wonder what that ad cost Ford?
  4. Big/tall tires?

    Waze is more accurate than your vehicle's speedometer, and it is also more precise, which means that the margin of error is less than your car's dashboard display. Federal regulations (49 CFR 393.82) permit factory speedometers to have a variance of 10% higher or lower than the actual speed...
  5. DH LTH

    Appears to be a good advertisement for Big Daddies Garage angled O2 extenders, at least so far.
  6. DH LTH

    8,000 rpm, wow, you are spinning it up there!
  7. 576 horsepower to the wheels, naturally aspirated?

    576 horsepower to the wheels naturally aspirated with just a few things being changed, stock block, internals, and cylinder heads, is pretty amazing.
  8. Building a 2025 mustang gt s650 - recommendations?

    So what did you decide to do?
  9. RPM redline on Tune?

    I was at the same track for the June event. It seemed brutally hot then, too. I had owned the car for a full three days. 🤣 Thanks for sharing a video. I think I need to get one of those Garmin Catalysts. It looks like the video using the Garmin camera is rock steady even at 140 mph.
  10. Dark Horse at Homestead-Miami Speedway in October 2025

    What is the device hanging from the windshield? To what is your camera mounted? And then the view switched at 3:55, I assume to the device hanging off the windshield. I am sure you already know this, but the view is much better, if it was not for the shakiness. Is there any way to get rid of...
  11. RPM redline on Tune?

    @krisk I need the opinion of a better, more experienced driver than me. What sort of speed are you hitting from 7 to 10A, and what sort of speed do you drop down to for making the left turn through 10A? I know you might have posted a video that shows mph on it, but I can't locate it right now.
  12. RPM redline on Tune?

    Whew! That makes me feel better. The one in that video was cutting out at 155 mph (and I saw a YouTuber saying his cut out at an indicated 158 on the dash). I can see that affecting a track day on some of the tracks with longer straights once the horsepower is bumped up. For example, Michelin...
  13. Big/tall tires?

    Looks a lot nicer than I thought it would.
  14. Big/tall tires?

    I had 3.73 gears in an 81 Z28, with a highly modified 400 cubic inch engine (6.6 liters, for you youngin's) huge cam, too much compression, headers, 4 barrel, aftermarket cylinder heads, and I went 140mph. The car was still accelerating, but, um, that was about 7,000 rpm, and no, back in the...
  15. Big/tall tires?

    A taller tire is the same as a taller rear gear, i.e., lower numerically. Who knows what gear he had in his 1971 Z28, probably 3.73 (standard for 1971, although 4.11 was available), with only 330 horsepower (actually a lot for 1971 but laughable for today as the Ecoboost would stomp it in a...
  16. Big/tall tires?

    I like how he had very little change to the rear suspension, basically leaving it stock and just addressing an issue of flex in one area and the camber (getting zero camber, the opposite of what most of us want for performance, but perfect for the drag strip). I also noticed he replaced the...
  17. RPM redline on Tune?

    Is it difficult to get rid of the speed limiter? I ask because I keep seeing these dyno tuning videos where they keep switching into lower gears to avoid the speed limiter. Like this one at Palm Beach Dyno (right at time stamp 7:15): If the speed limiter can be turned off, why not just...
