Here I have made a list of the cars that I know of. Do you have any information about other cars that had 901-30 engine, I am grateful if you could let me know.

[912-2.8]

Raj and Don:
Do you guys appreciate how kewel it is to have these things in your own shed? Us mere mortals look at pictures and 'fake' our 906 engines with under-ground cranks, GT3 rods, jag cap distributers and the like.

Keep up the interesting details, it's fun reading. Just don't piss each other off, life is too short.

Get out and drive, put a simle on that face and enjoy getting to own a piece of history.

I'm going to go whip the 'hamster' in my 912 and smile a bit myself and pretend it's a 'tiger' (906) :-).

BTW just so you know it is not unusual to take delivery of a car with standard engine or without an engine from the factory for racing the kardex by itself does not give one all the story esp in a race car...........

(raj , it's funny , that you were getting into referencing early grp. 5 , just as I was writing a reply bringing it up )

First off, regarding cars bought sans motors ..... then on to 906/R type motors & grp. 5 :

One example of this (cars less motor) , just to start , is the Dr. Dalio 1968 911S . That is shown on this forum somewhere. Ordered less engine , then I believe he was ordering an R motor to follow. But then upped the order to a whole 911R car.

I will be posting over at the new thread started by raj , (http://www.early911sregistry.org/for...-Rennen-models) on anything related to any possible special 1968 911S 'plus' cars.

For one, either Porsche built more R spec. motors (even in 1968 MY) than is chronicled. Or distributors/dealers/privateers built a good amount. As if your a student of 1966 - 71 european circuit & rally racing. You will find not only many entries noted as "911S" (or mysteriously noted just "911" , when other 911 entries in the same race / differant group - have the model specifically noted) entered in "group 5" . You will also find cars listed as "911R" listed in group 6 , or referenced in period news reports as "911R" . That , if you can find photos of alot them , you will notice they don't have 911R fenders , or plexi windows , or R turn signals.

Group 5 :

"Group 5 was an FIA motor racing classification which was applied to four distinct categories during the years 1966 to 1982. Initially , Group 5 regulations defined a Special Touring Car category and from 1970 to 1971 the classification was applied to limited production Sports Cars restricted to 5 litre engine capacity."

As far as I can tell , raj is just callling it as the facts present themselves. If anyone thinks they can know it all. Unless you were there , in Europe , as part of the factory - building - or dealing with procurment. Or a customer procuring this stuff , there is no way you could know all of what actually happened. And all that was available.

Also , in 1969 (at least in Europe) , if you look closely at photo's . you will notice the majority of Porsche 911 racers were still using 1968 and earler cars.

I'm still waiting for Hugh. H , and Claudius Z. , to chime in.

This is a great thread.... Wish I owned one of these cars described. Though there is a little strong feelings on both sides, I don't think it's gone too far, and it also brings out facts and opinions that are important to the delineation of these vehicles. If I "could" contribute you know I would.....

tks,
Eric

Here is a list of more 911L who competed. Although some pictures.

A word of caution......

Really interesting thread (apart from the personal stuff, not interesting and shows nobody in a good light!) but just a word of caution as we try to research all this great history.........I have seen numerous period motor sport events where the entry list, including type of car, is assembled from individual entry sheets completed by the entrants and often pulled together by somebody with a limited understanding/knowledge, so the guy with the 911R writes "911" in the car model section and "911" is what it is in the programme for the event and so on; the same is often found with cubic capacity declarations.

Not a resaon to stop the debate or the detactive work....just something to keep in the back of the mind.

Thomas, Tim et al perhaps you could help me out on this (and get the thread back on track): I think the 901/30 included in its specs the 911S camshafts, pistons and cylinders, 40IDS carburetors, red shroud and yellow tag distributor all combined with 911Normal heads with the smaller ports/valves. Accordingly, the engine spec was quite special for the sports kit cars and not really equivalent to a standard production 911S spec motor. Is that correct and if so what was the factory's reasoning behind the use of the 911N heads? Thanks, Tom

[Flunder]

Raj; Thanks. So a black fan shroud with S carbs, which had high speed enrichment circuits, longer duration S cams, 9.8 pistons and it seems the 911N heads. Perhaps the smaller ports of the 911N heads aided all-around drivability as the engine benefitted from higher port velocities in the lower engine speed range. in that era the factory was still a specialist manufacturer and the uniqueness of the sports kit 911L shows their desire to find the ideal combination for the needs of its equally unique clientele. It would be interesting to see a period image of a 901/30 sitting in a 911L. Thanks again for the specs, Tom

[Flunder]

Raj: I had missed that view in the video that Thomas posted. I agree, that is a very interesting shot. I think most restorers put a red shroud on these 901/30 powered cars, which is incorrect based on the factory specs. I seem to recall that AndyBoy has a car done up with the engine bay detail of redundant Bosch coils and Bendix fuel pumps - a very business like look and based on my experience with old Bendix pumps, a very good idea too! Thanks, Tom
