Hughes Engines Tech Center: How Can A G3 Hemi Hammer Out 886 Horsepower?


Hemi cylinder heads, both vintage and modern, have shown time and again that they’re able to support big power, especially in ported form. Couple them with the right combination of hi-po parts and it’s plenty possible to hit four-digit’s worth of ponies. Oh, and a supercharger helps too. Hughes Engines nearly touched a thousand via a build in conjunction with The Supercharger Store. A limited dyno run proved out the hair-dried Hemi, even though there may have been even more power left on the table:

Since this is the third GEN3 Hemi we’ve shown with a supercharger, you may think that is all we build—not so blow-by breath!  But they certainly do make a lot of power as shown by this engine too! This is another project in which we worked with The Supercharger Store.

This is also another case of leaving some more power on the table, due to rented time on the dyno.  With some more tuning, horsepower with 4 figures may be available (for you low information voters that means over 1000 HP).

That restoration experience lead to pursuing a degree in Mechanical Engineering and a career in manufacturing.
