Hi Guys,

How long should I expect a professional shop will take to set up and dyno test and take down a motor under normal circumstances.

Thanks

If the engine and the shop are ready to go about 6 hours

Did 1 yesterday. Mount engine on dyno stand and set up for dyno 2 1/2 hours. Hook everything up to dyno, fill a fluids and make all necessary checks 2 hours. Run engine, set timing, fuel pressure and break in 2 hours. Make first pull and all is well 30 seconds. Make second pull and ATI damper comes apart and sends pulley and dry sump drive arbor/pulley flying around dyno cell at 6200 RPM's. Spent rest of day on the phone paying next day air to get all the carnage caused by the damper (2nd time a ATI has come apart on us) here in a reasonable time so we can get the other 8 engines sitting here on the dyno. This is a dry sump, new Holley EFI set up so it took a little longer to set up. Normal carbed BBC's with tune time and no problems are usually about an 8 hour deal from start to finish.

Correct, it's over an hour setup, then it depends on how many pulls you do. When the shop dyno's motors for me, we wind up jetting the carbs several times, bumping the timing several times, and I run blower motors, so we usually do several pulley switches. It's easy to burn a day, but if you do a more simple setup and just a few pulls, Jamie is right, you can do it all in 6 hours.

I saw the carnage, that pully pinballed all over Brians dyno cell.

Plan on a full day, if it all goes to plan.

You have to pay close attention to your thread length on your bolts. 99.9% you will not use what ATI sends with the balancer....

First engine all day long. Second engine you load the tune into it and check, half the time.
