Wiseco pistons posted a great article explaining the purpose and function of the second piston ring. Many engine builders and engineers read this site and already know these details but for the rest of us who aren't experts there is some great technical piston and ring info in the article below. ...

This network is critical of Carwow videos. Are they featured from time to time? Yes. Why? Because Carwow benefits from having certain cars available that never were sold in the US market plus an airstrip they seemingly get to use whenever they want to (poorly) test cars. ...

Well, we are sufficiently teased and pretty much know all the details of the upcoming Shelby GT500 Mustang. The car has a dual clutch transmission, carbon fiber wheels, wider bodywork, and a nasty TVS2650 supercharged 5.2 liter V8 codenamed 'Predator.' ...

This is something a bit different hitting the market. Say hello to ALTi who specializes in CNC machined wheels. This is a new wheel company that has been in the works behind the scenes for some time. The difference with ALTi is due to the quality of the machining which means hand finishing is not necessary. There is no hiding of flaws this way. ...

This is from Car and Driver and that alone should make one pause regarding the result of this comparison. It certainly is odd the new Ford Ranger places last in the comparison considering it offers the strongest acceleration and best towing capacity. ...

This is an impressive beatdown by the BMW considering the Mustang is boosted with a Procharger supercharger and has a built Coyote V8. The F80 M3 is a DCT running the VTT (Vargas Turbocharger Technologies) GC cast S55 turbocharger upgrade. ...

BoostAddict is seeing more and more posts about chemical direct injection fuel system cleaning solutions. Color this website skeptical but over the years some pretty bad carbon build up (namely in Audi 4.2 FSI and BMW N54 motors) was posted and it took a direct physical solution to clean off the carbon deposits. ...

Yes, this is the same Heads/Cam Gen V Viper you saw posted the other day. It is a hell of a ride that is well driven and the owner has no problem posting his runs against just about anything. He runs some strong competition in the video below. ...

Ecoboost 2.3 liter inline-4 fans have some upgraded HPFP (high pressure fuel pump) options courtesy of Xtreme-DI. There are two pumps, the XDI-HPFP35 and the XDI-HPFP60. The HPFP35 is in stock and shipping for the Focus RS. ...

The Ecoboost 2.3 liter four-cylinder in the base Mustang and the Ford Focus RS are not the same. Actually, the Mustang's Ecoboost is quite weak. Just look at at a dyno and the stock torque curve. The powerband is ugly to put it mildly. ...

Quick KIA's? Yep. It just goes to show in the turbo era anything can be made fast in a straight line. The KIA Stinger GT with its 3.3 liter twin turbo V6, 8-speed automatic, and optional all wheel drive can certainly surprise especially once tuned. ...

Stretching out a platform a bit or profit is one thing but this sounds absurdly long. The next generation S650 Mustang will not appear until 2026 or later if Automobile Magazine is to believe (and they should not be believed). ...

We are starting to get an idea as to the design of the upcoming Ford Bronco. Last week an article on FordBoost reported the Bronco would have 2-door and 4-door models with removable doors. Well, the roof is also removable. ...

Let's interject some automotive humor in between the usual serious horsepower posts. The California DMV is, well, what one could imagine hell to be. Endless rules, lines, red tape, fines, regulations, bureaucracy, and little to no fun. ...
