FLATCAD RACING Bonneville 2011 Build

Buddy, Sorry to hear of your switching to another class. As it is for your safety, it is probably the best thing you could have done. Hope you set the records book on it's ear !

Russ, Dave- Thank you.

Well, I had to head back To Colorado yesterday. I had a couple of texts/phone conversations with Randy (wrenchbender), about what we thought we needed to do. When I turned on the computor this morning, I had this message and pics from him.

Great job Randy!!

"Here we are 14 1/2" (13%) setback down 4" the first pics show it without intercooler but with the injector gives you an idea where it will be in relation to the hood. The next ones show it with the intercooler. The blower should be just under the hood with the injector just poking through. The next pic shows the scrub under the car the piece of tubing is 2" square the oil pan is about 3" above the floor and the scatter shield is 1 1/2" so I will have to raise the front of the motor about 1/2" to level it up."

I think we will shoot for 2" clearance, and limit trave to 3/4" down, and 1/2" up. It's starting to look like one mean ass racing machine, IMHO!

Crazy, Cool, Very Nice!
I really whan`t to see this one down the salty road!

What about a picture of the hole car with the engine!? & injector?

Oh Man is that lookin cool. Gets me really excited!!! What happened to the exhaust manifold plate/engine tie in plate, or have plans changed. It's getting kind of squissy in there.

Any pix with the clip on yet?! The suspense is killin me!

[Bored&Stroked]

Push it back baby! I think we're now getting the dang engine where it belongs in a race car . . . under the damn cowl - then sticking up through it. I love it when the injector needs a cut-out in the cowl . . . now we're talkin'!

Given that we're in Vintage Comp Coupe and Vintage Altered Coupe - get that dang engine back where the driver can touch and feel it! We need about 10" in front of the block for the blower drive, crank support system and a bit more . . . the only decent way to do that is with a lot of engine set back. Also, once we have the engine back, then it can sit a lot lower in the frame -- I like the center of gravity low and I like as much weight on the rear of the car as possible. This year we're going for a manageable set-back . . . who knows, next year the driver maybe cooking eggs on the bastard and keeping his gweets warm.

I just love how the whole car is now coming together . . . with a bunch of 'stray dogs and cats' (all you goofy bastards) working on it from around the country - all working toward an August 2011 goal. This is what the HAMB is all about - commitment, collaboration and making the journey . . . with the types of cars/engines/builds that we are passionate about!

We have so much to do -- keep the momentum and focus boys . . . we've started the BVille journey and we need to keep humping it to the end!

Well...it is possible from out of the US - even without a ton of money!! It's gonna be my 3rd time this August on the salt...

Gonna be a while. Randy is working on body work, then we need to finish the setback, rework the firewall, and build an interior 'doghouse' to cover the engine.

I'd like to take this opportunity to welcome A Chopped Coupe and Strombergs97 to the FlatCad Racing team!

A Chopped Coupe brings not only racing experience to the team, but mechanical enginnering.

Strombergs97 specializes in carburation and injection- most of you have probably read some of his posts.

John, Duane- Welcome!

Buddy,

She's looking great....can't wait to see the car finished!

[38FLATTIE]

Nothing glamorous today, but necessary, none the less! Here's what

Randy sent me:

Well here it is 10:30 Sunday night and I ran out of welding wire so
here is some pics of structure repair and rocker replacement also note
that the doors now fit lol. So tomorrow after a trip to the welding
store ill get the driver side finished welded in an move on to firewall
replacement which I am looking forward to.

Rust repair, and drivers door before, and both doors after.

[Tman]

Ah yes, the unseen ugly stuff, nobody ever raves about rocker repairs! A necessary evil.

[38FLATTIE]

I like the engine placement- down low and set back from stock!

[38FLATTIE]

When I logged onto the computer this morning, I got a pleasant surprise! I received this email, and pics, from Randy :

I was able to get in the garage tonight and made some good progress here are a few pics. I got the firewall tacked in good and was able to get a little more setback we're now at 16 1/2" that gives us about 1" between back of the block on pass side and the firewall which is plenty of room. I also rolled some beads in the firewall hope you think they are ok. I also was able to get the motor mounts set in and the trans crossmember started I should be able to get that finished tomorrow and then I will get the injector hole trimmed out and keep movin on


So, a 14% setback. I can't wait to get home and work on this!

Good shit this.........................

Well Chris and I got together today and went over the SolidWorks cylinder head 3D model designs. Chris has done a fantastic design - using a lot of ideas that he and I have been chasing around for quite awhile (from our Flathead Ford and Harley explorations). We're getting pretty close to the final design.

Today we were going over the additional stud hole locations, figuring out where we can use 9/16 studs, where we have to use 7/16, etc.. We've added 7 new studs to the original Flathead Cadillac design - to add more clamping force in more areas. Hopefully we can prevent head gasket issues under boost.

I'm not going to show you the chambers - we need to hold something back for Gosh Sakes!

The heads are a 'clam shell' design - each side of the head will be milled from a solid piece of 6061 aluminum - 1.750 thick. All the geometry will be used to generate CNC toolpaths - for a CNC mill to do the work. There are a LOT of details to these designs . . . the combustion chambers alone take almost 30 minutes per chamber on a production CNC machine!

You'll see how we have a .125 gasket that goes around the perimeter and the plug holes -- this is to hold water as best we can. The gasket is kind of a square o-ring material that's used between blowers, manifolds, etc.. It should take the light pressure of our cooling system as it can handle 55 lbs of boost on blown alcohol motors!

Anyway, here are some images of the 3D models . . .

The Top - showing the cutouts on the inside:



The complete unit - with the water manifold on it:



Cool shit hugh!

Time to get Kevin to make a BIG FRIGGING pile of aluminum chips -- what you say Kevin?
