A view from the dyno console: see and hear a Type 1, 1776cc engine being tested on the JMR dyno at 5,000rpm.

The most significant step forward in tuning and developing engine combinations at JMR, has been the investment in a brand new engine dynamometer from Stuska Engineering, USA. Yes, this is the same equipment all the major engine builders in the States use to test an engine's horsepower and torque output and is the only facility of it's type in Europe. Via the instrumentation hooked up to the engine, I can assess any changes needed in carburetion and/or ignition timing and then tell whether those changes are providing more torque and horsepower. Basically, the dyno allows me to attain maximum performance from any particular engine combination. Also, the dyno has assisted in the evaluation of different parts combinations. No more guess work: if somebody claims some new wonder part gives them a 15% increase in power, I can check it out. No more bull! With the knowledge gained from several years of dyno testing various engine combinations, I am in a position to tailor an engine’s specification to meet the requirements of the customer; no guesswork involved - it’s all based on the information and experience gained from the multitude of engines built and tested on the street, strip and dyno. All customers who have had their engines set up on the dyno, have gone on to record their best ever quarter mile times and speeds. In some cases, people have brought engines to me that have been jetted so far out, that once corrected, they’ve benefited from as much as a 50% increase in horsepower!
What’s the point in spending thousands of pounds on performance parts and equipment, only to leave the final set up of the engine to guesswork? At best, it may result in excessive fuel consumption - at worst, it could mean getting into an over lean condition, culminating in meltdown. All engines tested on the JMR dyno are provided with a computerised printout showing torque and horsepower. If you know which gear ratios are fitted to the vehicle and other relevant info, I can run a computer simulation which will give accurate performance figures e.g 0 - 60 mph, quarter mile time and speed etc
You'll find more information on the dyno in the JMR Performance Guide and I'm sure you'll find the test results of the various engine combinations make for interesting reading.
