XXO/BVGC '38 Chevy Coupe Build

Website Head Handlebar Holder's comment:

Remember that this is an unofficial forum.  Dan is welcome, of course, to offer his observations and help and such -- but a proper "ruling" must be sought and received through SCTA channels.  

We on the Forum are, of course, very interested in how this wing/spoiler situation plays out -- but don't take Dan's comments here as the final word.

Right, Dan?

Edit:  I forgot a letter.

You are correct and I understand.  In my haste to work through this problem I approached it wrong.  I am looking for some input as to the possibility of an approach that might be legal.  I do not want to put Dan in an awkward position.

The nature of running a vehicle for land speed records makes you think about unusual applications.  Sometimes I get caught up in some crazy ideas.  I need somebody around to slap me back to reality.

Ok, since we started this here, I'm going to continue on with the progress.

Dan, I just sent you gents another email, that basically asks that if the first design is deemed illegal, will this mod make it a legal spoiler?

Of course, we welcome all opinions and ideas, as we are scrambling to get this done!

Got the email and responded. The gap must be filled, only a single surface can be presented to the air with a spoiler design.

JL222 - the Comp Coupe wing rules are written as presented by Tom Burkland and George Fields. If you think the 6" above the top of the body is wrong argue with them.

I am off the the GNRS and any posting will be delayed for a couple of days.

Thanks Dan-have fun at GNRS!

So, our spoiler issues are resolved, and we'll get on with modifying the car.

I don't understand you are making the car more slippery, drip rails- door hinges etc but will create more drag with those new vertical filler pcs. Looks like a big air trap to me plus maybe mess up the airflow over your new rear spoiler

Why can't you bring that flat alum forward to the end of the body belt line bumps, and have a little longer side plates?

Don,

The only thing stopping us are the rules!

From 4,CC.8- It can extend no further forward than the rear axle centerline.Spill plates are allowed to be no more than 8 in. above and below the forward mounted position of the spoiler when the spoiler is parallel with the ground and extend no more than 2 in. past the end of the spoiler.

Acually, we are more interested in spill plates than the spoiler. Don't get me wrong, we want the effect of the spoiler, but our primary reason for doing this is the spill plates. Look at the other '37/38's that run out there-these cars have a long area under the trunk, ans a short wheelbase, therefore they like to spin!

If anyone has an idea to improve this design, that is legal, we are all ears!

  The rule fits George's coupe just great.

  Why in the hell, anyone would think it would fit other cars needs an explanation from Tom and George and anyone who voted for it.

Can you narrow it up a bit so the bottom of the spill plates touch the side of the body to make the vertical face smaller without effecting their performance much?

  That would be the easy way and it would actually work. But lowering it down and back would give more area and downforce.

I'm not much of an aero guy, so I'm going to let John weigh in with his ideas. Now that we know what will be deemed legal, John is looking at options. I know John wants to keep as large of a spill plate as he can, out in 'clean'air.

[38flattie]

I'm glad you're happy with it -
I'm certain it will work well -
But gosh darn it, the lines on this car are just so sweet - especially the chop - I hate to see it have to go in this direction.  

Chris, I know you don't like the mods, and aesthetically, I don't either!
 
The car was built for Vintage class, with a vintage look. However, the engine shows more promise than even I expected, so why not take advantage of it? The only way we can really 'measure' our efforts, is to run against records set by successful teams-I don't feel breaking our own records, set in open classes, is going to prove much to anyone, let alone to myself.
 
I can't afford to build a whole new car, to move to the /BGCC and /BFCC, so our 'quest' is gonna get fugly!

....but it will sound real cool!

[lsrjunkie]

Fugly or not, I think it looks way cool! Reminds me of what people in the forties thought a car would look like in the future!  I hope it all works so you can get a hat that will match that purdy car!

Thanks Joe!

Ok, moving on with aero mods, our new, narrower axle showed up today! With the axle, new rims, and narrower tires, the front end will be 9" narrower!

Randy is setting this up to change out quickly in the pits. So, our new 'quickchange' front end will be installed for comp coupe class, with more 'glass work by John K., and removed for altered class.

[Glen]

Who made the axle, looks neat.

[38flattie]

Thanks Glen- it's a special order Super Bell.
