Hemi Pistons Baby! MAHLE Motorsport Introduces Top Alcohol Hemi PowerPak Piston Kit

Top Fuel and Top Alcohol engines are some of the most bad ass pieces around and they inspire awe among anyone who gets to lay eyes on one. They are incredibly similar in many ways, but just different enough to mean that not all the parts are the same. This mostly revolves around the difference in cylinder heads and the fuel being burned which means that compression ratios can be significantly different between the two. While a Top Fuel engine might have a compression ratio somewhere around 6.5 or 7:1, a typical Top Alcohol engine will run 11 or 12:1. That means the piston’s compression height and design will be different. If you want more information, and to buy a set for your combo, see all the info and links from MAHLE Motorsport below.
