You can go to these websites and try to match your build. Could be close.

Most likely you will be happier from talking to the guys at the boat ramp, they all seem to know it all. Bud

Tonto try to use Kemosabe calculator to figure power of his fire breathing single mag ground power war horse.
Image

After many trials of failed countings, Tonto come to see that no calculator can show so great a number, as it is the power equal of a great many bold horses that Tonto ground powered war horse produce.

It has taken lumber of many great trees to restrain Tonto Fire Breathing Ground Power War Horse from galloping to RPM levels, that only the great spirit can see the height of.

Such power is a great gift to Tonto, so much power that Kemosabe wise and powerful calculator can not even comprehend.

Tonto now no longer worry. Tonto only proud knowing of the great sound of thundering single mag galloping war horse, that Kemosabe can hear from distances greater in length than the longest rivers of life .

You can call Summit & Jegs, and ask to talk to a tech and give them your parts list your motor is built with, they will get you close to your hp and torque specs ...

measure the length of the block, and multiply the girth of the block and divide by how many "beverages" it took to build it.

Who the hell is going to let you use their dyno for $150???? Nobody in this world.Most get at least $500.

If you know someone it's 150 for me I don't care what it cost you but that's the only way to know what you got I'm sure one of you experts can just look at it and tell what it makes hehehe

I've used several computer dyno programs in the past with good results .not in knowing horsepower but in checking changes to see what it could do. there will always be variables, timing, air density, fuel and a lot of other things.
Is this a auto engine or aircraft?
With the auto atleast there are tons of builds and info. On the the aircraft there seams to be a lot less info. Plus there is a ton of mixed manufacturers engines using lycoming, continental , and an array of handmade parts.
Plus how will you check the heads for flow and the engines volumetric efficiency .

To get a price like that you will most likely have to know someone that owns
a dyno because nobody dynos them that cheap. I paid 200.00 for mine to be dynoed and have known the owner for several years. He normaly gets 500 to 700.

If you know all the motor specs then post them. There are some very smart people on here that can give you a real close educated guess/estimate of your horse power. It will be just that, a guess but it will give you a close idea of what you have. You will also have to weed thru some a$$holes to get to the good ones but thats always the case.
