3.6 and 3.8 numbers?

[GJB]

[FONT=Trebuchet MS"]It's been a while since I was involved with 964's so |I don't have access to the numbers anymore.

The standard 964 and 964 RS originally had 3.6 litre engines. Does anyone know how many cars and which models Porsche sent ex-factory with 3.8 litre engines? Standard RS 3.6 was rated at 360 bhp, what was the 3.8 litre engine quoted as ex-factory for bhp?

Also what capacity is reckoned to be the maximum achievable without making the engine reliability unacceptable?

I always thought the standard 3.6 in the RS was rated at 260bhp, rather than the 360 you mention?

According to that Jurgen Barth book there were 90 3.8 engined cars made by Porsche, including the 3.8 RS & CS and then the RSR.

Standard 3.8RS were rated as 300bhp and the RSR were 320-340 bhp depending on spec.

This seems an acceptable output, you can obviously go higher, but then run into the fine line between road and race engines depending on how often you fancy a rebuild!

We have recently had the discussion where no two RSR will have the same output, depending on spec required and passing of time etc...

[FONT=Trebuchet MS"]Typo...standard 964 250 and 260 for RS. I blame the drugs...

I think it is down to having GT3's imprinted on your mind?

Remember. the mk1 Gt3 had the 360bhp engine. []

A very knowledgeable source has it in writing from Porsche that they made 55 3.8RS (total for standard and clubsport) and 51 RSR.

I quoted Jurgen Barth as he was supposed to have got his data from Porsche for "The Porsche book".

As time passes and more gets posted on the internet, I am sure there are a few versions of "official" production numbers! []

I doubt Porsche know the exact numbers Paul...probably just depends on who is replying at that time lol!

Jason - I've heard numbers of 48 and 51 for RSR. I believe that 51 is the right number though. McClean or Howells will know for sure.

Ben, Paul Mc has it in writing its 51.

But as I said above probably depends who you ask and when these days...

 

[964rsdatabase]

The letter in question quotes the number of cars on the Porsche database but not the actual number of cars produced. I have both 3.8RS and 3.8RSRs on my database that 'don't exist'. I also have photos of the corresponding VIN plates to back it up. I'd love to know the totals though. []

Hang on...So your data base is more accurate than Porsche own records?

Do they know this (or care)?

Is this a bit like the 1500 (approx) 2.7RS they made and the 4000 that are left 40+ years later? []

No disrespect to your fine record keeping, but can Vins just appear, especially if you now the sequence was 001-055....what if car 057 appears due to an apparent Vin...does this necessarily make it the real car #57?

 

[964rsdatabase]

Put it this way, the highest VIN in the 3.8RSR range on the Porsche database is 6104. I have photographic proof that 6107, 6108 and 6109 exist (which probably means 6105 and 6106 exist too). Two of which still have the protective wax coat on from delivery, have never been cleaned, have 0km on the clock and are in the UK. Not sure how an owner would source parts for these cars as when asked for the VIN will probably be told they don't exist!

Maybe there is a separate 'special build' database that we don't know about. [8|]

Porsche data is a little spurious to say the least.

There is nothing to say there are actually more cars produced than we believe, but as the values go higher and cars move between international borders and markets, no doubt more cars will "appear" some on Porsche data base, others not!

ORIGINAL:

In terms of numbers built the figures in the letter stating 51 RSR would appear right. That would mean 6060 through to 6111 to get the 51. I may know why at least 1 of those cars you listed above is not on the database. If you pm me I'll explain.
