$100,000 PAT incometer measures bore cylindricity of a Katech billet block. The gauge plots the bore geometry out in a 3D model and measures to the micron. Measurement is done at operating temperature using hot oil pumped through deck plates.

Here is the plot of this billet block. Bore cylindricity is very good!

Pretty cool but why didn't you use a CMM ? I can measure that cylinder with a million data points + or - .1 micron . Who makes that machine ? Interesting probe head . I'd like to hear more about the build , hot honed billet block is how I'd like to start a build .

Too cool for school right there.

The CMM is not as accurate for measuring cylindricity. Incometers (Inner Contour Meter) are the quickest, most accurate way of determining Roundness and Cylindricity of bores. With the accuracy of ± 1 micron, Incometers quickly determine circularity and cylindrical form by taking a multitude of measurement points from inside the bore.

More information will be posted about this particular build when it is ready.

It is great to collect the data but how does the information collected allow you to machne the bore to a higher standard?

The bore is hot honed until a proper bore geometry is achieved. The hot honing process uses the deck plates I talked about in the first post. Hot oil is pumped through the block and the hone is done at operating temperature to better simulate the conditions when the engine is running.

This process was so confidential in 1998 that the hot hone was installed in a separate, locked room. It was one of the keys to winning Le Mans 6 times and all of the other endurance racing success.

Wow I am very impressed.

old news.....I've been using the hot hone process for years on all my bitches!!

Yes, we've been hot honing since 1998, but not a lot of people know about it so I wanted to post part of the process here.

I was referring to a different type of honing.....



Seriously, very cool stuff. Thanks for sharing with us!!

I think you are refering to hot boring.

I've had to measure bores cylindricity in relation to another plane and a micron was more than my total tolerance . I'm not sure what kind of CMM you guys looked @ but I can hold .2 micron with a 10' 1/4" shear 60' away chomping stainless . I've seen CMM's that measure down to millionths . I really can't see how that would be more accurate than a CMM but it's still cool while being affordable . I think the unit would be affected by the high temps . Jason needs to cough up the details on this build .

I don't doubt that you have done that, but there is a reason we spent $100,000 on a PAT gauge when we already have a CMM. There are things that the PAT gauge can do that the CMM can't.

So is this/will this process be used on the short blocks you build and sell to the public?

The block in the video is actually for a private individual. We can, but the cost:benefit is not usually enough for the average street user. We reserve it for the more extreme builds and all of the billet blocks.
