Coltrane Welding and Fabrication is excited to offer dyno services to the New River Valley. 

We have an in-ground DynoJet 248 chassis dyno rated to handle 1800hp and 200mph. The unit also includes an integrated wideband oxygen sensor to map the car's air/fuel ratio through the pull so that you can tune for maximum hp and safety. Additionally, our model 248 is equipped with the Eddy Current loading option which can greatly help in tuning the vehicle.
