  1. Fuel life/Octane loss

    This is exactly why they sell ethanol free gasoline, for people to use in their boats and lawnmowers and pressure washers and small engines that get infrequent use. Ethanol free will last much longer because it's much less hydrophilic, but eventually it layers and lacquers. The issue is...
  2. Fuel life/Octane loss

    Not necessarily. All air has moisture in it and over time, the alcohol in the fuel is hydrophilic and pulling the moisture out. It's not as bad as it would be sitting outside, but it's still collecting moisture from the air. Also, the fuel is starting to stratify and separate and over time...
  3. Fuel life/Octane loss

    Fuel doesn't go "bad" in a short amount of time, what happens is the alcohol present is hydrophilic and attracts water. It also tends to separate and layer (which can be remedied easily with sloshing around under driving but upon restart, until it's mechanically worked, it can be a problem)...
  4. REVan Evan Mach 1 Street and Track Testing at Willow Springs

    If you actually READ what I wrote, I don't think it's loud because of the firing order, I think the firing order makes it sound trashy. I think MOST coyote exhaust videos don't sound good, they just make the exhaust LOUD and therefore guys think that's a great improvement. It's my personal...

    The problem down low is that simply mashing at a different starting rpm will yield a different curve down low (drastically). If you mash at 800 rpm or you mash at 2000 rpm, your torque values at 2500 rpm are going to look different.

    I'm skeptical. I'm betting (not having seen OEM dynos overlayed) that whatever torque advantage there is (if any) will be marginal/negligible. I'm betting, that JUST like the GT350, everyone complains about the gutless nature of the car because of the gearing. I'm betting that if you drove...

    The 3160 ratios in there are the GT350. Not sure what you're looking at. With 3.73 rear (same as GT350) and same trans, whether or not the GT350 is geared for street use is gonna be the same problem for the Mach1, maybe slightly less with a SLIGHTLY better torque curve lower in the band.

    This is from Tremec themselves with no mention of a ratio change: Why Ford Chose the TREMEC TR-3160 Manual Transmission For The 2021 Mach 1 This is from Car and Driver again no mention of a ratio change: 2021 Ford Mustang Review, Pricing, and Specs (caranddriver.com)

    yeah, except that's not verified anywhere I can find on the interweb. If Ford elected for a new ratio, I can't find it. It's certainly possible, but would reduce some of the efficiency of using the same spec as the GT350 (even though the 350 is discontinued, Ford still has warranty legacy to...

    Unless someone chimes in otherwise, with 3.73 (and assuming Ford doesn't alter the 3160 ratios) it's going to be the same for the Mach1.

    Thanks, and no worries. You're not alone. And there's nothing "wrong" with your view or assessment. Just different cars for different folks. The Mach is a great car. Once Ford ditched the garbage MT, adding the tremec to the yote motor now eliminates a big turn off for a lot of drivers (and...

    Please don't take this the wrong way, but it's been a lingering complaint against the GT350 for some time. Many driver's who just aren't accustomed to driving a high rev motor feel more comfortable in the traditional, big American V-8, hence the sales of the Chrysler boats. Even the cadence...

    How long can a valve bodied auto last when abusing it up and down the range of gears for extended periods and under harsh/hot conditions. It better have some SERIOUS cooling, as anyone who's ever towed anything up and down hills and mountains in an auto will tell you it's a fast way to burn up...
  14. Gen 2 5.2L - Does it push more HP? Truth or rumor?

    Yes, but then I'm running all raked/weirdo with 30 series in the back. The only solution is 305 squared, which my wheels aren't setup for (running OEM R specs/offset). And the cup2's weren't enough traction for the car max'd out N/A with 4.09's let alone now (with a blower upcoming). In...
  15. Gen 2 5.2L - Does it push more HP? Truth or rumor?

    I have 4.09's in the back now, and prefer the performance of the cups, but I do NOT like the scraping, the car already scrapes enough as it is, now worms everywhere duck when I'm around. If Michelin or Toyo made a 315 or 325 in 35 series and a 305 in 35 series (cups) it'd be most helpful in...
  16. Gen 2 5.2L - Does it push more HP? Truth or rumor?

    The 315/30/19 in cup2 comes in around 26.5 lbs. You're correct, 3 lbs spinning at radius saps torque and power. However, just as important is the fact that the 315 cup2's are 26.5" tires. The 305/35 MPSS were 27.4" tall. The effective gear change just from the tire diameter is like going...
  17. Gen 2 5.2L - Does it push more HP? Truth or rumor?

    It would be the first one that resulted in changes that didn't change anything all of us as car enthusiasts know to increase horsepower. Anyone with half a mechanical brain can see why/how the gen1 vs gen2 vs gen3 coyote puts out more......from increased displacement to increased compression...
  18. Gen 2 5.2L - Does it push more HP? Truth or rumor?

    Pedal commander makes a fortune convincing people (through customer testimony) that it makes the vehicle faster when all it does it change the throttle input profile and ramp in more throttle with less pedal travel. But you'll get all sorts of people who swear their vehicle now has more....more...
  19. Gen 2 5.2L - Does it push more HP? Truth or rumor?

    Except in this instance, the baseline is the motor is putting out the same power. And there's no facts to support that, just "it feels better." The burden isn't on me to prove that the motor outputs the same power, because Ford has already claimed that. It's up to others who are convinced it...
  20. Gen 2 5.2L - Does it push more HP? Truth or rumor?

    Prove it. Show some sort of data. Otherwise, it's just placebo. And as I said, I doubt Ford would be spitting out motors from the factory that fall outside their power confidence interval without changing the rating. Slapping on Cup2's WILL give the perception that the car is stronger, but...
