What happens to my bike on the dyno?

We load your bike on the dyno, strap it down, enter some data. Check the tire and go through a warm up cycle. Then we subject the engine to a load at various RPM points. At these points we take a sample of the exhaust gasses created by the engine.

Can my bike fail on the dyno?

Dynamometers subject engine to load to measure horse power. Just like the iron man contest, Pointless having the strong guy pick up a pebble. You have him pick up the heaviest bolder he can manage. The point is "to see just how strong he is" If the said iron man has a damaged back , picking up the bolder may not be such a wise idea. The point is. Dyno's don't break engines. A failing or not so healthy engine may fail while on the dyno, Chances are it was going to fail anyway when you hit your favorite open track, ]

Should I run my bike on the dyno?

If your bike has been making knocking noises for the last week. The answer is no. If you and your buddy put in some new cams and it's a bit noisy, no! If it ran out of oil last week and you just want to make sure it's still sound, the answer is no.

Now if you have a well maintained bike, regardless of age; then the dyno won't do any damage to your bike.

How much does it cost??

Like anything in life, it depends on exactly what you want. A base run, just to see the magic numbers, will run you $50.00. Dyno testing with exhaust analysis and F.I. mapping (power commander, Tune Boy, TEKA, Yoshi) or carb jetting; will cost $400.00 to $500.00.

Some may ask "why so much". The best guys on the job, with the best equipment available, with the best results doesn't come cheap.

What can I expect for my investment?

Chances are you are seeking dyno work because the bike does not perform as you expected, maybe after a bunch of add on parts or what ever reason. Most times you are getting beat. A dynamometer is a measuring tool. Just like a tape measure; except it costs about a thousand times more. It allows us a window into how the engine is running in it's state of tune. And from there we make adjustments or modifications to improve the performance of your machine.

Do I need an appointment?

Yes.

Why So much fuel??

Unlike the other dyno machines. We do things a little different. When mapping the entire fuel map of the bike. The engine is run up to ALL the load points and held there for approximately 4 seconds.

So imagine you going up a hill of varying grade. (for explaining purpose we will use 100% throttle) ((I'll use the GSXR750 I tuned today))

Flat out @ 2000rpm 4 seconds, 2500rpm 4 seconds, 3000rpm 4 seconds, 3500rpm 4 seconds, 3500rpm 4 seconds, and so on to 14000 rpm. So you can imagine the testing involved now for 100% throttle, 80% throttle, 60% throttle, etc.

Now while doing that, a lot of time is lost monitoring the engine temp, radiator temp, oil temp and rear tire temp to avoid exceeding recommended ranges. If any of these parameters threaten to move outside the expected values, we shut down the run until the they return to safe values.

A Hayabusa, on a typical summer day, will take two days to finish, plus two-and-a-half tanks of fuel.

You wanted it right didn't you?
