Sprint Car Engine Combinations


The building of Sprint Car Engines has been a passion of mine for years..

I have spent years and accumulated countless hours researching, testing, and developing engines specifically for sprint cars. In that time we have produced some fantastic combinations with proven track performance.


Building a engine with big HP is not a problem these days, but developing a engine that promotes forward bite and still makes enough grunt to set fast time is the trick!


For the past few years building the most horsepower is not what we have strived for in our non wing engine combinations, rather than smooth drivable power that allows the driver to hook his car to the track.


A car that is hooked up will be a lot faster than one blowing the tires all the way around the track come feature time!  


Take advantage of our experience and desire to win!
