For weeks, maybe months, I have noticed a coolant smell sometimes after driving my car. My wife noticed it, too, with no prompting by me. I checked the coolant level, and it is above the minimum. Is this a normal thing? Has anybody else noticed a coolant smell after driving? It is...

I don't think he is a member here, but I saw this on FB on the 2024 S650 Mustang Gt / Dark Horse page. Erik Andre Radzins, and the rest is a quote by him: MICRO RECORD UPDATE: Your thoughts? Back story, this Dark Horse is bone stock other than the ProCharger P-1X supercharger kit and a used...

I have a beautiful blue ember metallic paint . . . covered in white spots like I rinsed it in milk. I am on a well, probably drilled down into a calcium cave. Anybody on a well have any tips for me? My prior car was silver, so I never noticed this before.

The question is in the title.

I wanted to ask those of you who have used Michelin Pilot Sport 4S tires what you set for tire pressure. I have had these tires wear in the middle first (in the center of the tread rather than at the edges on either side). My Trofeo RS tires did the same. Accordingly, I have been...

Ran across this strange thread - a guy is asserting that he was able to manage heat . . . I run my Whipple PP car on track a fair bit. It is an absolute hoot. I have added a belt bar and run a 5 point harness. I have the larger intercooler from Whipple, and I run a stage 1 system. I have coil...

First you have to remove the three pins (not sure why they did not take these out at the factory or why they are installed in the first place). This is a GT 500, but it is the same, and shows in detail how to to remove the pins.

LMR installed a Whipple on their Dark Horse with a manual Tremec and took it to Motorsports Park Hastings in Hastings, Nebraska. I don't know what the temperatures are, but everybody is in shorts and T shirts (EDIT - 71 degrees). It is also not a serious shakedown run. It looks like they are...

In the following video, a man uses his extreme summer tires in 24 degree Fahrenheit weather (-4.4° C) and does some panic braking tests. Wow, it takes a long time to stop, way longer than it takes in the summer with these same summer tires. It is true. Summer tires are hard like hockey pucks...

PS4S stands for Pilot Sport 4S. Do you drive on them? If so, have you experienced cracking as a result of cold temperatures? I have driven on them over several winters and have experienced nothing of that sort, in spite of all the online speculation and hand wringing. What about you? Have...

This gal is tracking her A10 handling package Dark Horse over on TrackMustangs and sharing her experience. "My lap times at my local track were massively quicker than my GT, quicker than a Mach 1 with a comparably experienced driver, and on par with a modified GT350." He also commented: "I...

The Whipple Stage 1 pulley is 3.875" - has anybody run a larger pulley, e.g., 4", 4.25", or 4.5" Whipple's install manual has a chart showing that going from 3.875" to 4" drops the boost from 11 psi to 10 psi. I am guessing maybe we could get it down to 8 with the 4.25 and maybe 6 with the...

If I were to install Kooks 1&7/8" long tube headers on my car, will it sound terrible? I actually like the sound of my Dark Horse right now. I read dismissive comments like, " Great way to add only 20 horsepower and make your car sound terrible at the same time." Will they make my car sound...

Long version: Short version:

Now that tuning is out for the S650, E85 for fuel is a real possibility. This video is an excellent tutorial about ethanol as fuel, and, even if you already know about some of it, you will learn some new things within just a few minutes. It will answer questions such as, why is 1.63 used as a...

So I see for tunes they say, first, you have to buy some device. Then, you have to purchase credits. Then you purchase the tune. What are credits? Please explain like I am stupid and have no clue. I am not really stupid, but, in this case, I have no clue.

So it looks like the Michelin Pilot Sport 4s tires on the handling package stick out more. Or is it the carbon fiber wheels?

Has anybody used these? They come in the same sizes at the Trofeo RS https://www.tirerack.com/tires/tires.jsp?tireMake=Pirelli&tireModel=P+Zero+Trofeo+Track&sidewall=Blackwall&partnum=03YR9P0TT&tab=Sizes

Anybody use these for track days? I was thinking about getting some with the tread width and tire height matched as closely as possible to the Trofeo RS that came on my car (ignoring the 350mm, etc., just match up the specs). They are a lot cheaper than the Trofeo RS. YouTube reviews on track...
