I have not posted in a while but had a quick question on the roll structure plating. Had you considered leaving "gaps" in the corners to facilitate the use of driver extraction tools in the event of accident? We have had issues in the past with fully plated roll structures. Great looking build, workmanship and execution of the design.

  Good point. I'll bring up your concern with the design team and let you know the result.

The roll bar cutter in use by SCTA is exactly that.
It does not have the piercing, spreading, scissors action that is found on other devices and the bite is limited.
Steel sheet over the required structure is the strongest for an LSR type of crash and perhaps it is time to rethink the rescue equipment abilities.
The available money could not be better spent.

It is my understanding that the newly purchased tools do not require a "gap" in order to cut the cage if required. I am not personally involved and don't know exactly what was bought. I do know that your money was wisely spent.

Really like your drivers module, that is one stout piece of fabrication. Great thinking. Also like your engine bay, makes it easy to change motors, which it sounds like you plan to do a lot of. Might want to make that scoop a little bigger and higher for that big block, air next to the body is "boundary layer" and hasn't much speed.

Great looking piece, really looking forward to see it and all of you at the Salt!!!!

  Thanks for the comments. I'll take the scoop comment to the design team.

With the roll structure plating does the driver have “120 degrees of adequate vision forward”? (3.U)  Or does the rule only apply to the windshield and assumes an optically clear roll structure?

I don’t mean to pick on your design I like it, and many liners that have been in use for years also appear to violate this rule. I just wondered if anyone ever received an official interpretation of this.  How far back can we push the driver into the roll structure?

In this area where the scoop is, it could be that the air flow is creating a "vacuum" by a speed of 250+ mph close to the body work - one of this strange aerodynamic phenomen by high speed. With vacuum I mean - there is not enough air pressure so close to the body, the pressure flow will be app. 2 inch over the body in this area - the effect comes from the windshield step.

Well, did you run this with the Caddy flathead?

And....?

Motor is a BBC. All aluminum, I don't know the HP,owner of the engine says he thinks it should get us over 200 mph.Body panels are painted but not yet installed. Attaching some more build pic's. As soon as we have the body panels on I'll get pic's to you. Frame is in four major sections bolted together. Hope you won't hold it against us but am trying to get attention and still have some "WOW" factor for Speed Week. Will send more build details as time allows.
 Ed.
The record in A/GL is 274.813 so one would hope to run over 200 mph. :evil:
This engine is only intended to Shake down the car and get our drivers there license's. The car was built with the intention of using more than one engine combination in the future maybe Diesel or as mentioned by Pops a high output Dodge 4 banger.
 One of the engines in the mix is a Flathead Cadillac. Some of us think there is more to be done with the vintage engines. Attached are a few pic's of a new head. The combustion chambers are a proprietary design and cannot be shown now. Don't have pics of the pistons or con rod's that are in design. Also block girdle and reworked block.

Ed, I see you on the board from time to time. I was just wondering what ever happened with the Caddy flathead build? Those are trick looking heads!

Don, thanks for taking the time to talk to me today, and for the info! That Cadillac flathead sounds mean.

Good luck on the record chase! :cheers:

Hey, flattie.  Do you care to share.  I don't think it has yet to run with the Cad.(?).

No, it hasn't run yet. The goal is to run this August. I can't say much, as it's not my build. I can say, that I talked to Don (Pops), and Bob, and both were great guys.

Our build are very different, on many levels. We are sharing information that benefits both teams, and will help one another where we can. We are a little further along in the engine design department, but Bob has somegreat ideas.  Bob invited me to see the car and engine, so I'm planning an April visit.
