Will, I don't have before and after numbers, we coated it as part of the build. I'd be interested to see some real testing numbers too from one that was taken out, coated, and replaced with no other changes. A lot of things play into the setup. The first truck on here was .020 over, Hamilton cam...

Let me know what you find on the Megasquirt, haven't played with one yet but I'm sure someone will show up with one before long.

The glowplug circuit could be modified to do the same thing I think.

Another point of note, we've been running the Cerakoted manifolds and turbo housings now for a couple months and it is holding up extremely well. In the future I plan to do the bolts as well so the heads don't get rusty. Not seeing much temp difference in the cooling systems using the coating on...

Couple of new things I've been working out. The TPS from the Dodge is different enough the I wasn't getting a good voltage swing, so I made an adapter to run a GM TPS. This works well but lacks the last 10 degrees of travel as the Dodge linkage is about 75 degrees vs. the GM 85 degrees throttle...

Hi Sandy, no, not using the grid heaters. Most of what we do are fair weather drivers and the Cummins fires right up without them. If I had a call for it, I was just going to make up a timing circuit using a 555 and firing the relays. I'd most likely add an IAT sensor as well so as not to cycle...

So the week that was; Up to this point we had been using the billet freeze plugs while building our Cummins motors, this build the goal was under 500hp motor, mostly stock, not a lot of frills. Ok, the Nickel plated gear cover was a frill, but it looks good. Turns out that the gasket set we used...

Neither. We've looked at using coated tappets, and quite possibly will on the Sand Toys next motor. We are using the coating on Pistons, Turbo housings, manifolds, and recently a radiator to see if there is a difference. The coating process itself isn't that difficult, just time consuming. If a...

Ha! Naw, it's just work...or play, depends on the day I guess.

The 6.4 Cummins we are building for Steve will have Diamonds Steel Cummins pistons for testing in a street driven hot rodded engine. Turns out the head of the shop at Diamond worked at our shop years ago when he was first getting experience in CNC machining, funny how small the world is. :-)

Yes! We get to work with Trend. They have been doing valvetrain testing on it. So now you know if you get pushrods and components from them and they give you advice or data it's actually been tested. :-)

Someone asked me about the rollers. Yes, they are the heavy duty ones from Harbor Freight, and yes, we modified them to stand up to the heavy trucks and the wider tires by welding 1/4 x 2" straps onto them as hopefully you can see in the picture. If we make more they will be fabbed by us and...

We're working out the straight cut gears, but notice it has a cam support. The harmonics pulses from the engine and mechanical pump set up will start twisting violently and snap the helical gear or camshaft when you start pushing above 1800 hp. I'm sure that below that mark you are dancing with...

Next motor will be a 6.7 with a Hamilton Cams 12v head, 13mm P7100 pump, Waterman mechanical fuel pump, 3 turbo compound, and the conversion gear case that we developed. The shots of the gear case displayed by our friends at Trend/Diamond Pistons at UCC. The shot mounted in a truck was Power...

This one went the other way. We pulled the 6.2 diesel out and replaced it with an LSX engine. It's getting caged, long travel suspension from Rod Hall racing, King bumps stops, 4 Caribou suspension seat, Holley EFI, and paddle shifting for the 4L80e. Shooting to keep the weight under 6K.

If anyone is looking for a military project, we have this out back of the shop. Steve has talked about selling it.

There were 2 more outside :)

Pre-oiling before you start a new motor is very important, this is our "High Tech" oiler and it works beautiful. Doesn't get any simpler. I remover the handle and replaced it with a -4 to 1/4 npt fitting. On the Cummins I attach it to the power steering pump oil line and pull to Turbo line. As...

It has a 2-1/2 body lift, it's not quite as tight as it looks, and yes, the body gets lifted to adjust the valves, pretty simple actually. Ha! the duals happened because the owner took the covers home to paint them. He took the wrong set when he did, which, no biggy, just leave the one off the...
