“NEW” 4 CHANNEL DATAMITE – Exhaust Temp, Crankcase Oil Temp, Carb Air Inlet Temp, Torque, & Horsepower


Here’s an example of a datamite system with 4 analog temp channels.

Not only can you measure normal head temperature but now you can measure exhaust temp, crankcase oil temp, carb air inlet temp and see torque & horsepower all in one report. Put in the report the range of data you wish to look at, (say 4000 to 6500). Put in the increment of engine rpm you wish to see, normally 100 rpms for unrestricted motors. Put in the range of average data you want to look at (5500 to 6400). Remember, you may wish to toggle back & forth between the numbers in this report and your acceleration report data so think of that when choosing your rpm ranges. Also, don’t forget to look the bottom of the columns for average data in the range you set. If you or your customer has several motors, dyno & compare each and see which one is the strongest in the hp column. Then also switch to the acceleration report to see if that motor is also the fastest in acceleration from the range you’ve chosen, (5500 to 6600), for example. If you’re using a My-chron #3 or #4 or one of the newer Digitrons, you may be able to download your data from your local race track and give it to your engine builder so he knows the range of rpm you use at your local track? By using the acceleration data, he/she should be able to fine tune the engine (internal/external parts) and get you a much wider engine rpm range to help you on the race track. Going fast cost money, so don’t be surprised if you need a different carb, cam, header, etc.

The engine builder should be able to prove to you which parts made a difference on your engine so you’ll know their not wasting your money! They should also be able to dyno your clutch and see if it’s working also. A new Bully or Tomar slips at about 1.5 to 1 with metallic discs. If you’re getting beat on the starts or on the restarts, your clutch may be the problem, not the motor. They should be able to see how much your clutch slips and at what rpm it hooks up.
