What is the going rate for dynoing a motor?
How long do you get to monkey with the motor?
Do they have misc. fitting`s for water / fuel hook up?
Do you bring it down there just like it was going into the boat?

I`ve called a place & they seem more than fair, just checking how you guy`s all do your stuff. Thanks as usual, Tom

You pay for dyno time :)hammers

So it's best to do your homework and have all the prep work ready.

You will need to get your jetting and timing base lines dialed in.

You may wish to try a different induction, exhaust system and boost levels

It all takes time and money, but can save you a butt load on headaches in the end

Check with racers in your area and ask the dyno operator questions on your set up

Good luck :cool:

When I took mine to the dyno I called ahead to see what was needed .. He used his starter, msd box, and all the cooling parts .. I took 5 gallons of 93 and 5 gallons of 110 and brought back home alittle of both .. He charged me $300 for a 4 hour session ... Best advice I could give is just ask the dyno owner what is needed from you, and Rock On ... I got pretty lucky, I didn't have to do anything to the engine other than set timing and adjust the carbs... Good luck :)hand

With regards to dyno shops you don't always get what you pay for. Some shops charge more and you get less in terms of tuning help. Others charge very little and you get more help than you can ask for. The going rate around your neck of the woods is 600-1000 bucks per day.

In order to waste as little setup time as possible, call ahead and find out the best way to plumb your engine so the dyno operator can get it hooked up and running as quickly as possible.

A good dyno shop will help you tune the engine, ask the right questions before firing the engine up, and spot any problems before they turn your engine into junk.

Bring your own fuel and your headers and any tuning parts (spark plugs, jets, spacers, scoop etc) you might want to try.

If the shop is capable of data-logging O2 sensors in every pipe using its own headers, give that a try.

I'd recommend Westech Performance in Mira Loma or Paul Pfaff Racing in Huntington Beach. Both have very knowledgable dyno operators that will help you get the most of the engine safely.

Like others have said, be as prepared as you can so they don't spend hours hooking things up that you will end up paying for.
I wanted to be as prepared as possible so I made this stand to mount it on with all the electronics and fuel pumps hooked up already.



It bolted right to the dyno frame and I brought the long bolts along too.
Made a 4 wheel dolly to set it on to roll it through their shop with also.

A big question is going to be the water pump which a jet does not have.
You may have to bolt on a GM water pump to hook to the cooling tower in the dyno room.

This is all good advice!
One thing I will add is go to the shop that will be doing the dyno and if you can sit in on a dyno! Just to see what goes on and get some ideas on what to do! And make sure that all of the dynos systems work so that all of the info. from the pulls is there! Information is a great tool for anyone that helps or setsup your boat!

Someone say Oldsmobile ? ? ?

My shop built my engine the way I wanted it built and did the dyno for FREE ! Well it cost me $200 for an Olds bellhousing ... but it was worth it. Only time I didn't watch was after he went to 5600 rpm and said " next stop 6200" ..... I went outside for a beer or two ..... ;)

As said before, you pay for the day, so the less time you spend getting things ready, the more time you have to play.
Here are a few things that come to mind:
Plumbing is a big issue. Know ahead of time what's going to be required to get water through your engine, inter cooler, etc. If you need adapters, special hoses, an automotive water pump or whatever...try to do as much of that ahead of time as you can. Blower enignes with cam driven water pumps are typical of such needs. With Jet boat engines, bleed water from the dyno can be plumbed through the engine...try to make two lines into one for your water inlet.
Same with fuel systems.
Exhaust..if you have specific exhaust requirements, find out in advance how to accommodate that. Most dyno's won't run wet exhaust...some will. It's always good to bring your own headers if you can and can run them dry.
Oil change...if you want to do an oil and filter change, bring it with you.
Carb tuning...don't assume the dyno facility has the jets and/or parts you'll need.
Have your timing set close enough to start the engine.
Have your cold valve lash set.
Prime your oil system! Otherwise you have to pull the distributor and prime...sometimes with some hyd. lifters this can cost valuable time.
Go over the engine and check to make sure things are tight.
Dan Olson block mounted oil coolers will usually get in the way of the motor mount. Try to figure out an alternative so you don't have to figure it out at the dyno.
Hope that helps.
