Thanks Mike! That was QUICK!!!   Sorry about the name mix up. I corrected it.

Burns is tops. I emailed them about advice on welding SSteel. They came back to me in hours. DR, your stuff looks great. Mike.

Mike, I have been looking into coatings and just cant get my hands around how they spray an even coat.  Does that mater much or is there something more I am missing? I remember in the old IMSA  days talking to our engine guy from  Roush, and he would say they would go through a bunch of sets of bearings after coating them to find enough shells to make the perfect set.

Tony, I don't coat bearings but I have used them. They do have a build up but bearing shells very in thickness from the parting line to the center of the shell anyway. You measure for clearance just like any other bearing. That being said if you ran a standaed bearing uncoated you might need a extra clearance bearing if it's coated. I don't see the need, and many of the Nascar engines I've worked on don't have coated bearing either.
I do like coated cam bearings because of the spring loads during startup.

That Burns stuff is pure art!

Even has a proper "goilet".   Wow.   I need to talk Midget into a stuff of this quality.

    Go Mike go! Can't wait to see your son(s) run with the hairdryer(s) power.      vic

Transmission inspection....

Mike,
I have never had the opportunity to take one of these trannies apart but looking at your pics when you shift into high gear, which I assume is the front (input shaft end) dog ring does it disengage the input gear from the counter shaft?? I am assuming that high gear is 1:1 with the power going through the main shaft.

Mike, the upgrades are looking good. Think you will have it all done in time for El Mirage in May or would that be pushing it?

Looking good, Mike!

As promised, the 321 stainless headers with the cast stainless flanges. Goes nice with the new collectors....

Hi Mike

Do those cast flanges stay flat when welding, when using a single flange you can hold it in a fixture for a final mill cut to make it flat for the gasket seal.

What do you do with those type of flanges for flatness?

Those parts do make a nice & clean looking header, does the collector stay floating?

Stainless is neat to weld just like welding butter just flows and looks great after with all the colors in the weld to see.

Just another example of first class building.

CONGRATULATIONS........all three of you.

Don,

Yes they stay flat after welding, and if not a simple touch up on the 20" disk sander fixes any issues. We don't use header gaskets and yes the pipes "float" in the collectors. I've been involved with endurance turbo engines for over 30 years, many on the salt and the current method I use has worked out the best for us to date.
Thanks for asking.

Rex, yes 1.0:1 in 5th is how we run this trans and everything through the main in high gear.
