NACA 66 Special A/BGS

I'm pretty sure I have a box with spare floaters and discs too.  Need to make sure they fit the AFT.   Only problem wil be the total height of the clutch package with the bellhousing your looking at.  You will need something @ 8" or more in can depth to accomadate the clutch as a 2 disc or 3 disc and a throwout bearing.

We think the water tank will be one of the more difficult sections of the build as it houses two pumps, one radiator, is partitioned to separate engine cooling water from inter cooling water and is a structural part of the chassis.

wow, that's more complicated than our car!

Great to see this project moving along Rob.

I'll give Mike at call at B and J tomorrow.
He said that he might have can for me. If I have to, I might modify it for the ground clearance that I need. It will still be 1/4 steel plate but I would lose the SFI cert.

Happy New Years all!
Brandon and I have been making some progress on the water tank.
You can get a little video tour here.

LOVE the driving position!   it will be nice when we get the unread fourm feature back!!

[jdeleon]

Nice looking work!   Did you find out about the bellhousing?

[robfrey]

No. I'm sorry. Keeps slipping my mind to call him. I have left myself an alarm on my phone to call him tomorrow (Tuesday).
I was also thinking about engineering a face tooth coupling in place of a clutch but that would be pretty time consuming. A Clutch like the unit you sent pictures of is probably our safest bet.

Wow, This build is outstanding!

Have you talked to Bob Brooks at AFT Clutches? The guy is great, and should be able to help you with your clutch needs-he'll make exactly what you want.

[robfrey]

Thank you very much for the compliments on our build.
I think we have a clutch that will work from jdeleon but now we are on a quest to find a bell that will work with this clutch and the B & J trans.
The stickler is that it needs to be designed for low ground clearance.
I will probably just have to modify a standard bell.

[Peter Jack]

Take a look at some of the late model stock car stuff. They tend to run the power train really low and often make the bottom of the bell housing flat. Multi disk clutches are the norm.

[robfrey]

Yes but those clutches won't take the kind of torque I will be putting though it and they are not available with 1-3/8 x 10 spline. Also the bolt pattern and pilot dia. for the trans is different so I would have to make an adaptor plate.
Got to be an easier way.

[Peter Jack]

I wasn't thinking of the clutch. It sounds like you may have that solved. I was thinking only of the bellhousing which should be easily modified for any transmission pattern.

Rob,

You mentioned possibly foregoing a clutch, and using a coupling.

You might look at a Dodge or Woods coupler- very easy, very dependable, as long as you gets them lined up good. We use them on everything up to 2000HP traction motors, running 0-100% constantly. You might check and see if they would handle the rpm's- they will handle the torque!

Rob, take a look at this from my machine tool days: www.stoffelpolygon.com

As a certified motor head I always thought this might find a race place! 

[robfrey]

Pretty cool Woody! I have never seen those type of drives before.
