    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...

    A little more apples to apples, the Boss Mustang is a little down on torque, a little up on HP, and accelerates a little faster than the same gen GT. Track Tested: 2012 Ford Mustang Boss 302 vs. 2011 Ford Mustang GT (edmunds.com)

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

    You guys are making my head hurt so I had to look it up. According to wiki, the physics definition of "work" is force x. displacement (distance). HP is a measurement of power, or the RATE at which work is done. And "acceleration" is the rate of change of velocity. Focusing just at the crank...

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

    Just my basic understanding: Torque is a measure of force, or ability to do work. HP is a measure of how quickly that force can be applied, or how quickly the work can be done. So to pull a trailer you want torque. To accelerate a car you want HP. Lots of complicating factors with gearing...
