FlatCad Racing's Quest for 200 MPH-a Cadillac Flathead Story!

Well folks hope everyone had a good christmas just thought i would do a little update on progress. I fitted the new hood top so john (wzjunk) can get the new hood scoop fitted to the car. I will be taking it to him over the weekend sometime.

Looks good. I am laying up some of the flat panels today. Hardest part is keeping the shop warm enough to cure the fiberglass. It is avery cold day?

John

 

Well, While I explore ways to blow the engine up, others are actually making progress!

From WZ JUNK:

Attached is a picture of the first mock up for the outside of the scoop. I will be looking at the shape some.

Most of the fabrication of the air intake is done.

 

I sure am glad john is doin that 'glass work hell im still itchin just from trimming and fitting the hood lol! Looks good im thinkin i better get the periscope ready to be fitted so you can see buddy lmao

Gotta give WZ JUNK props- He's a helluva craftsman!

From WZ JUNK:

Attached is a picture of the two fiberglass panels I made by laying up resin and fiberglass on a flat sheet of plate glass. I will cut the flat areas of the scoop enclosure out of these panels. That starts tomorrow.

Attached picture is of the completed air duct. Note the rubber collar near the Enderle injector. The air duct is in two pieces under this flexible rubber collar. This will allow the engine or the body of the car to flex or move some without stressing the hood and scoop.

Most of the green tape you see in this picture is my way of making a flexible tape measure so that I can keep everything straight or aligned as I build the enclosure for the air intake.

Wow that does look bitchin........ Great job John

maybe I can get some tips on glass repair as I suck at it.............

 

That is some beautiful work . . . keep cranking team - spring is just around the corner!

 

Hi All

here is an update on the new main caps.
this shows the increase width on the new front cap compared to last years



Here is the new center Cap being machined -- big difference


here it is with the old cap over-layed on top of the new design


next step is to drill the bolt holes and alignment pins, then set up and do the final fit grind and off to Boyd enterprises for the line bore and valve grind

 

Awesome work, Don!

 

Here it is in the block for comparison !!!

Old

NEW !!!


THIS SHOULD HOLD HER TOGETHER !!!

 

Damn Don that is beautiful........

 

On another note, Russ Meeks, Finish Line Coatings, has the valves coated, and is shipping them to Don. Bearings are headed to Russ to be coated, and the new head chambers will follow.

PIstons were coated last year, and still look great!

I really think these coatings help our cause!

 

Great looking work Don - we're doing everything we can think of to make this sucker as strong a possible. Lets hope we have big enough band-aids in the right places for nitro baby!

 

Can't wait to hear it leave the line!

 

I can't wait to hear it wide open going across at 206 mph.

 

Can't wait to just hear it, period!!

 

Like I was saying Buddy , you guys put more work in your block than most put in there entire motor, I think the nitro will be good for ya, you gotta a hell of a good engine crew on your team, Hell you have a great crew all the way around!!! Tim Jones

 

Great job pops29, those caps looks perfect!!
Sure hope the bottom will hold at 800hp.

Hey Kjeil, you coming over this summer to do some racing with the FlatCad crew? We'd love to have yah!

 

38flattie, Why don't you just continue the oval shape of the bugcatcher to the air opening????? What is the difference in the square inch opening of the scoop as opposed to the opening on the bugcatcher?

this is a great thread......good luck in '13

 

Thanks for the words of encouragement ! Like Dale said I hope one day you will make it to the salt

 

Like a lot of other things in life, what seems so simple becomes complex. Here is a little information about how to figure the size of the opening and the recomended shape. http://purplesagetradingpost.com/sumner/bvillecar/bville-scoop info-1.html

It turns out that in the flat cad situation, the area in square inches of the 3 butterflies in the injector equal about the same area as the air inlet opening. The area of the butterflies are what limits the air flow but the math just came out that way. Alternate shapes and sizes will change air fuel ratios and airflow.

Bonneville is a strange situation. Some of the shapes of the cars seem odd when you first look at them and then later you find out why they look that way. There is a lot going on at high speed and a lot to learn.

John

 

Thanks for that insightful info, John!

I've just returned home, from a very good trip.

I caught up with Dale, Amy, and crew chief Mark. We had a nice dinner (translates into big drunk), and then made plans to go to Ross Racing Engines. The next morning, we dropped the crank off, for a .010 grind and nitrade on the rod journals, and a polish on the mains. We also dropped off the rods, to be checked for straightness and stretch.

I then headed over to robfrey's, to see the NACA 66 Special- what a classy build! Rob, thanks again for the hospitality!

Don is finishing up the main caps and girdle, and later this week the block will head to Boyd Enterprises, for a line bore and a valve job.

Tomorrow, I'm heading out to see Randy and John K.

We're getting closer!

 

Hi All

Here is a small project for the Flatcad.. Buddy needed a pump for the rearend oil,, so he supplied me with a 12 motor and a pump and here is what I did.

the mounting plate is machined out of 6061 alum. to bolt to the c face on the motor

the offset block is to be welded to the mounting plate




here it is mounted


now with the pump mounted

 

Here is a few pics of the new main caps after finish grind and fitted in the block

 

Great Work Pops, A quick question does the center main caps lay snug against the block or is there an air space?, looks like an air space in the pics,,, Thanks Tim Jones

 

Hi

Yes there is an air space on the angle cut only of the center cap , we did not want to remove any of the webbing at all -- very little there to begin with . but the top edges of the cap are machined and ground for a light tap fit same as the bottom of the cap,, we will be looking at cross bolting the center cap also .

 

Thanks for the info, Tim Jones

 

Don, fantastic work! If we break it now, I bet it won't be there! Lol!

Randy and I just got back from John K's. John is a fiberglass genius! The snorkel and hood scoop are all but done!

Next up, an 8" narrower front axle.....

 

Dont mean to hurt youse 'alls feelings but that thing is getting FUGLY! The price to pay for speed
