Thanks, those are fascinating photos.

[Bill Sherwood]

Thanks Neil, good photos.
The two-valve and the latter foru-valve F1 engines are the ones my friend Adrian used to work on at R-B.

Thanks for the photo's

[NRoshier]

you're all welcome.
Picture 6 is the crank seal. RB reasoned that a std seal of the day would not last the rpm, so they used a piston ring type of seal.
Picture 5 is obviously the chain drive, which is completely dismountable as shown for ease of servicing. The cogs drive their shafts via a slot in the cog/shaft.
4 shows the main caps cross bolted
the row of nuts on the top are the main cap bolt ends. The reasoning was that this would ensure that the main case was not unduely stressed and would be easy to check. Block was sand cast.
Pic 2...rods are carillo's!
Sump has the pumps at both ends enclosed so there is no external pump...pipes are prone to leak, get damaged and burst!

Anyone have any contact info for the magazine?

[McGuire]

Bump... hope folks don't mind.

I would very much like to contact "Race Magazine" (which I assume is an Australian publication) in regard to these photos. If anyone can help with contact info I would be much obliged. So far I have been unable to come up with anything.

The guy posting just above you is the editor.;)

Attached here is the 5lt version of the Repco Engine Developments engine (after Repco split with brabham) in the MRC Mk2 sportscar. This 2 valve (4 valve were not able to run) engine gave 470bhp. The man in the brown coat it Don Halpin, who was Brabhams chief mechanic and who now has all of the patterns and does the rebuilds for the world on the RB/RED engines.

McGuire what can I help you with?

Not quite true... in fact, not true at all...

There was at least one, I think two, 4-valve dohc engines ran in the sports car class. Matich with the SR4 and Ayers (original owner of this car) with his later Rennmax monocoque car. This passed on to Jim Phillips, who continued to run it, and I'm sure it ran with the quad cam 4-valve engine. Strangely, I don't think Janey's McLaren had a quad cam engine... or did it?

The only restrictions that applied to sports racing engines of that size was that they couldn't be over 5-litres (which included a 1.4x factor for turbo- or supercharging, so anything that wasn't naturally aspirated had a limit of just over 3.5 litres), and they had to run on petrol.

It's going to be interesting, by the way, when people mix up Race magazine with Racer magazine.

[NRoshier]

Happy to be corrected. The information came from Lionel Ayres, whom I spoke to during the week in regards to his ol MRC Mk2 car pictured (yes it's in the next issue!).
He said that the 4V engines were banned for the 69 season.
Race is still going, I believe Racer has now changed to Ignition Magazine, but I do not see it around much.

[Ray Bell]

No... Ignition is a new magazine put together by the former editor of Racer, which is about to experience a rebirth under responsible managment...

For a certainty Matich continued to run the quad cam engine through to 1970. Whilever he had the SR4 it was so powered, and it's highly unlikely that anything else was considered. The heads were either the same as or derived from the 1968 Repco F1 heads.

You have to be careful of what some of these old boys tell you. And of their memories, which tend to fail from time to time. I've just been reading the Vintage Racecar Tasman articles and I'm surprised at how much detail is simply wrong.

The errors, I'm sure, come from a combination of lack of understanding of basic information supplied, poor memory and feathered egos. The lack of research in checking for possible flaws is inexcusable.

Do you want me to check over your article on Lionel's old Rennmax/MRC (Mk2!) Matich SR3 replica?

By the way, good piccies...

[NRoshier]

Ray, perhaps best if you call me, as I do not know you or your relationship to the other magazines, so you can perhaps understand my caution. I can be contacted on the email address above.
I was actually hoping that Ignition was the continuation of Racer as I have been advised to take action against Racer, to get it to change its title. Do you feel there is reason to be concerned WRT the competition

[Greg Locock]

Neil, I was just reading the article about the red Escort with the dual injector setup. In it there is a photo which implies that they sync the on-board video with the data acquisition channels. Is that right? McGuire was looking for that ability a few weeks back.

BTW, the mag's quality has improved leaps and bounds, in fact we were discussing one of the articles during a vehicle dynamics meeting a couple of weeks back.

When you set the website up can you put a huge link to : Brian Beckman's Physics of Racing series. http://www.miata.net/sport/Physics/

[NRoshier]

Greg, that is correct, the video and data channels are recorded simultaneously and when rewinding or reviewing one it will automatically back up the other data channels to the same time point. In this way the camera has been used to check tyre/suspension etc as well as recording the other data. I do not know whether there was real time tyre temp recording with the other data streams, but I believe this to be the case with some teams.
Glad you and the others have found material of interest.
WRT Beckman's material, I agree that it is a great resource, one I was going to tap into.
