***DYNO day***

[Tim @ P.I.S.]

Personally i like to refer to a dyno as "The Great Humbler".


And Allen is already hitting me up for a date for the next dyno day.

Every brand dyno reads different, hell even the same brand down the street can read alittle different than the other.

A dynojet model 248c has become the benchmark in the diesel world. This is what i believe Dunbar and Maddog use.

I have no experiance with these. I do have experiance with a Mustang 1100 series. I have put numerious pulls on one, and with back to back runs they always come out exactly the same as the last. That is awsome consistency. And consistency is very hard to find with some other brands. With my experiance the Mustang 1100 runs aprox 10% under what the 248 model runs.

#'s taken from a dynojet and then run thru a 1/4 mile calc I am told match actual 1/4 mile #'s. THis i can not verify, just what i am told. I do not have easy axcess to a 248 or a 1/4 mile though to find for myself. But this is the supposed reasoning why the 248 has become "the" dyno to use by others.

In my eyes all you need is to a find a "good" dyno and operator and stay with that one while setting up your truck. You need only to get #'s to work with, it really does not matter who's dyno as long as you stick with the same one.

Hope this helps.

You are correct AND the person in the truck can make #'s do some strange things.
