Freshening your engine is an important part of maintaining your racecar.  Often times problems can be discovered during the freshening process that would otherwise lead to disasterous results.  Whether we built your engine or someone else did, let us perform your next freshen up.

  • Completely disassemble and thoroughly clean all parts

Engine Dyno Service
We have our own in-house engine dyno.  We use the Superflow Xtest dyno system capable of testing engines up to 2000 horsepower.  So much can be learned about your engine by running on a dyno. Without testing your engine on a dyno you are forced to test by the costly trial and error method at the race track and are left to guess at its performance level.  Have your engine dyno tuned in our shop and we can work out the best tune up for your engine before you ever go to the track.

Chassis Tuning Service
We have all of the equipment necessary to help you setup your chassis.  We recognize that building high power engines does you no good unless you can apply the horsepower to the ground. A properly tuned chassis will increase you car's performance as well as it's consistency. Bring your car to us and we will weigh it and provide you with a base line 4-link/ladder bar setup.

Differential Repair/Setup
We offer complete drive train service and that includes the rear differential.  Whether you are changing gear ratios, need repair work or just want an inspection, we can help.
