Carl, great videos!

Thanks for all the kind words and support, everyone!

I'm at our racing patron saint Don's place-D&D Engineering in Turlock. Don doers amazing machine work! We're aligning the tranny precisely with the block. Hopefully, Don will post pics of the process!

I gotta give the team kudos here, from the vision, design, workmanship, and implementation-all turned out great! cheers

What an exciting trip! I was scheduled to leave Monday. Easter Sunday, after everyone had left, I was getting all the parts ready I needed for the trip. My wife suggested that I leave, so that I would not have to drive straight through. As I was asking her if she was sure, I was loading the truck as fast as I could!

After stopping to see Wayno (it was a blast), I arrived mid- afternoon on Monday, and John and I unloaded the engine. Later in the afternoon, John got it set on the dyno. I checked out Chico, then picked Dale up from the airport.

Tuesday morning Dale and I chatted over breakfast, then headed over to Vintage Hotrod, and spent most of the day hooking everything up. Late Tuesday afternoon, we fired the Flatcad for the first time! We were pumped, to say the least, and headed for steaks and drinks. The waiter put too much ice in our drinks, though, and hurt us a little!

Wednesday, after several aspirin for the ice overdose, Dale and I headed downstairs to have breakfast with Don, Carl, and Jim, who came over to watch the festivities .I left my paperwork on John's desk, so until he sends it to me, I'll go off of memory. First run we had it set real fat, and pulled around a 185 HP at 4500 rpm. . We leaned out the next run, set the timing, and got 351? off of just over 7 lbs boost. We kept at it, until we reached the 570 HP, 544 ft/lbs torque, at 5500 and 14.2 PSI boost. Sooo, back for steaks and drinks!

Thursday I settled the bill with John, and Dale and I got the engine ready to travel, loaded it up, and I took off for Don's shop=D&D Engineering in Turlock, CA.

Friday, Don had several guys jump in and help, and not only did we get the new oil pump idler pulley assembly made, but got the bellhousing lined up correctly

The trip home included 24" of snow on Donner Pass, rain into Utah, and being stuck on the interstate in a snowstorm, in western Wyoming, due to an accident-But I'm home!

The only issues we had were a poorly installed freeze plug, that popped out, and the Barnes/Esslinger oil/water pump. The water pump didn't work at all, so we went to an electric pump. The oil pump bolts to the water pump, and the whole setup was put together at Barnes, then installed by us. By the 6th pull, the bolts c]ames loose on the oil pump, some even fell out! I'm pretty sure we bent the shaft, and tore up the vanes. It will be interesting to see what they say Monday!- see pic

I have to give Don and John props here- if you need any machine work, or laser cutting, give Don at D&D engineering a call. He's a Flatcad sponsor, team member, Hotrodder, and a helluva talented guy!

I wouldn't even think of taking an engine somewhere besides John, after our experience! He's a proven engine builder, takes the time to explain everything, and is 1st class in his approach to getting things done!



We're going to 'ease' into this, slowly and as methodically possible, on the dirt and salt this year. After we're done running, we're going to tear down the engine, and look for the tweaks that might bring HP, without adding more boost-head flow, cam, ignition, etc.



1st pic is breakfast Wednesday morning- from the left, Don, Carl, Jim, and Dale.

If in doubt, it probably IS a mistake.

I think about basic parameters you guys started with, the age of the design and the compromises that were built into place before you even started the build.  This is a great acievement.

Well played!

Thanks Guys!

Here's what we did at Don's place, in Don's words:

Well Buddy is finally home from the tour of California !!!
We spent the day at my shop aligning the bell housing to the center line of the crank shaft ( the center line of the crank has been moved up towards the cam ) and also Designing a new tension bracket for the oil pump. I first built and alignment tool on the lathe to mount to the rear of the crankshaft.

We machined a shaft on the lathe and finished the mounting surface and bearing diam. between centers to make sure there was no run out .. we used a wide roller bearing on the end to mount the indicator to. We then mounted the shaft to the crank shaft, then mounted the bell housing ((((( SORRY ABOUT THIS DALE !!---- BUT ----------THIS IS WHERE BUDDY GOT THE HAMMER IN HIS HAND ))))))))

We dialed the trans pilot in within .002 to the crank. We then drilled and doweled the bell housing with 2 each 3/8" dowel pins.

We also laid out the new tensioner with auto cad , laser cut a 16 g sample for testing and lasered the finished part in 3/8"

If it doesn't go force it, if it breaks it needed to be replaced anyway!!!

When you have a hammer in your hands everything looks like a nail!!

Hit it again, Buddy!!!

Buddy, just three steps!

1.) Measure with laser!
2.) Mark with chalk!
3.) Cut with sharp axe!  cheers

Buddy and Dale,

Best of luck on the dyno. Anyone willing to take a guess at the HP this beast will make. My guess is 550-600 HP depending on boost.

Tom G.

Buddy and Dale,

Congratulations I never had a doubt about the HP numbers, as that is the easy part. Keeping the motor together for the runs required is another story. You have all the HP you need, now just concentrate on reliability and you will set a lot of records. I am very happy for you, it has been a great journey so far, I wish you the best at Bonneville this year.

Tom G.

Thanks Tom and also to everybody else on this thread -- we really appreciate the support, the kind words and the interest in the FlatCad.   It was a fantastic week to say the least!

I spoke with Barnes, and sent them the oil pump back. They said they doubted there was any damage, due to the fact the pump shaft is supported on both sides. When you turn the pump, you can feel the vanes rubbing, so I have to believe there is some damage, even though there was no metal in the filter.

I’m back at work until May 6th, then home for the thrash, to try and get ready for El Mirage. I have to install the new water tank in the rear, fuel tank in the front, do all the plumbing, a lot of electrical, and get the car on scales.

It will be a thrash, so if you’re close, and bored….. grin
