TA race cars. Hydraulic or manual clutch?

['Cuda Hunter]

Did the race T/A cars in 70 use a manual or hydraulic clutch?

I bet they were a manual.

That is what I was thinking but figured the guru's here would just know that answer off the top of their heads.

not sure , I have not been close enough to one to check , Barry should know

mechanical linkage

They used mechanical linkage- why mess with success? Hydraulics didn't really become popular in racing until just about 20 years ago or so. Mechanical linkage is usually obvious when it has a problem, and is much easier to fix in the pits on raceday.

  A lot easier to "bleed" as well.

I don't know about that, Aussie. I have always had the worst time getting any fluid from the bleeder screw on the z-bar!

I'd vote for hydraulic.....this AAR recreation (no idea if the Gurney cars and the T/A's were prepped the same) was painstakingly researched during the build - notice 3 holes for master cylinders and 3 resevoirs in the tank above where the masters go (2 for brakes, 1 for clutch). The exhaust was pretty crazy on these cars, I don't think they had the room for the stock bellcrank.

Hydraulic.  This is the engine bay of one of the Gurney #42 AARs.  You can see the resevoir on the right side of the picture.  Notice the headers -like ntstlgl1970 said, there isn't any room for a bell crank.



Here's the engine bay of the #77 Posey Challenger, currently owned by Ken Epsman.  Same resevoir.

Thanks alot! 

Got any more?

[NoMope Greg]

A few - just the engine compartments or the whole car?  I even have a little video that shows the rear suspension that I took for HP2 earlier this year.  They were intended to be photos - I didn't realize it until after the fact that I had the camera on the video setting.

Mostly engine bay pics or anything that is modified from the regular AAR's. 

  Havn't seen many of these photos.

Here's a few:

Rear suspension:


I'm afraid the only other ones I have of the T/A and the AAR are on the track and not of very high quality.

  Great pic's, noticed alternator on drivers side of motor so better fuel pump access and is that a cage/shroud arrangement around the clutch pedal? possibly stopping foot from hitting wrong pedal on turns?   
  Cars back then were always having something new tried so mechanics had to improvise as most "hot parts" just wasn't on the shelf then like it is today.
