    2012 Mustang 5.0 - Misfire

    Sorry for the slow reply I missed this post. Yes, I replaced the engine wiring harness and all misfires resolved.

    2012 Mustang 5.0 - Misfire

    If you’re still getting random misfires check the engine wiring harness carefully, especially where it attaches to the front passenger side of the timing chain cover. It’s secured tight against the cover at that location and over time my harness had chafed and worn through and 3 wires leading...

    A/C Problems Need Help

    OP, did you replace the expansion valve? Top of the firewall behind the engine. It can get stuck either open or closed and should be replaced with any compressor or condenser change. Cheap and easy access on our cars.

    200 Treadwear Options

    Plenty of faster and "grippier" options for sure. GRM maintains and updates a good overview summary of the most common players, it's a good place to start: https://grassrootsmotorsports.com/articles/track-tire-buyers-guide/ If your tires are 2015's they are aged out in any event. New...

    Watts Link Question On My '09 GT

    Either an adjustable PHB or a Watts Link will get your axle centered. Which is better is very much debated and seems to be largely a matter of personal preference. Lots of really fast guys on both. The WL allows easy adjustment of rear roll center which can be nice. Project Budget 400WHP...

    S197 GT owners: What’s it like as a daily? Coming from a New Edge GT

    Agree with others here, an S197 is a great daily driver, do everything car. I bought an '11 GT glass roof MT 5 years ago with 25K on it and now I'm at 140k. Year round daily driver in New England, ski car with snow tires, commute to work, sees 5-10 track days a year. I see about 20-22 mpg in...

    S197 Coyote prices?

    Seems like it's a great time to sell my s197. The only problem is its a terrible time to buy another one to replace it!

    Will there will be a run on S197 cars shortly?

    To me the s197 glass roof is a bigger deal than the s550 IRS or interior materials. I think the s197 as perceived through your butt and your hands actually feels lighter than it is, especially with some basic mods. But visually, because you are sitting down low and with a long hood, it feels...

    Strut Tower Brace....Fact or Fiction?

    If you take the stock bar off notice how much extra room there is in the bolt holes on the brace, I guess for mfg tolerances? With such a loose fit and so much space for the strut tower to move, it's hard to see how a couple 5/8" nuts torqued to 20 ft lbs or so are going to make any noticeable...

    Hot Rear Brakes

    Obvious question but was the piston retracted all the way back in when installing the pads, and was the piston rotated correctly so the nubs on the brake pad line up with the cavities on the piston? It's easy to do with the proper tool but a pita without. It seems unlikely you have two...

    why does everyone want to spin the coyote up to 8000 plus?

    Norm, I'm not trying to argue with you and for sure I'm no math whiz. But respectfully, yes I can follow the gist of your math and going back to your post #68, when you are talking about "torque in the vicinity of peak power rpm...", or "power varies more with rpm than torque does," those are...

    why does everyone want to spin the coyote up to 8000 plus?

    Norm, you are over-thinking this. :) Putting all the variables of downstream gearing into play isn't "rigorous," it's "unknowable." There are infinite variations and possibilities from car to car. With the right gearing you could theoretically move a train with a motorcycle engine. The...

    why does everyone want to spin the coyote up to 8000 plus?

    I think it's more helpful to not think about transmissions and final gearing, etc., it just puts too many variables in play. Imagine the s65 in the M3 and the coyote in the Mustang are just hooked up 1:1 to the wheels. I am pretty sure, assuming the weight of the cars is the same and you could...

    why does everyone want to spin the coyote up to 8000 plus?

    For sure you are right, there are a lot of variables with the M3. But in a general sense it makes the point that a car with a LOT less torque but similar HP is posting similar acceleration times. How about the Boss vs. GT comparison? Those two cars are pretty much identical in terms of...
