Viper Racing’s workshops are equipped to the highest level. Equipment includes turning, milling and drilling machines. Gas & Electric Mig welders, hydraulic Press, air and electric high speed grinding equipment. Ignition Test Rig, Benching and Storage equipment. We pride ourselves on our cleanliness, accuracy and attention to detail.

So remember, all Viper racing’s tuning work is developed using our own engines and verified on our own dyno’s. You will never be a “guinea-pig”, but will always be guaranteed the best, most useable and reliable power possible.

Similarly with any rebuild or repair work, we will produce a report and/or email images of any parts that need to be replaced. we will at this stage produce a fixed price quotation and await your approval to proceed.
