Engine to dyno connection?

[MyDuster360]

We just got our 2004 GSXR 600 and id like to get it on the dyno(Stone Bennette Corp. model# D-100 water brake)to get some baseline numbers.

I was wondering how everyone goes about hooking the engine up?

To be the most accurate, I was going to try to attempt to hook it to the crank. Then i thought maybe the trans output would be easier.

i figure id get some oppinions.

Direct drive off the transmission output should be a good option. Check the RPM limit for your dyno, many don't like to go over 10K, which means you'll need the transmision to get some reduction in there...

DON"T use a chain drive if you can help it, they wear out, and throw off your numbers...plus tensioning and lubing the dyno chain gets to be a real hassle, just one more variable that you don't want to have to deal with.

The spec sheet states 16K as the upper RPM limit so i think we're good there.

This is how we did it.

Before anyone says anything, that is just a parts engine. We also built a 1/4in steel cover for the shaft (just in case something breaks) not shown in any of these.

thats basically the exact setup we use with our r6 and a land and sea dyno. Just a coupling and a shaft.

We use a very similar setup too. Most books will tell you to go this way for long dyno tests.

what books do you guys use? i am looking for a good dyno book, and I have yet to find one that focuses JUST on dynos. thx.

Engine testing theory and practice is a good place to start. It's by Michael Plint and Anthony Martyr.

It's not technical but it presents the general safety/layout/choice/acquisition of dynometers.

Hey Matt, is anyone still on campus this summer? I'd like to come poke around the shop if I could. I'll be back in the burgh this Wed/Thur/Friday if we could line up a meeting time.
