944 Le Mans Car.....

[Ex Skyline]

....Can anyone point me in the direction of the full spec' for this car please? [8D]. Many thanks in anticipation guys [].

 

[944 man]

Well: there wasn't ever a 944 Le Mans car, which will be why you cant find it. The cam cover on the engine said 944 on it, but it was a twin cam 16v turbocharged special - essentially a 924GTP with a different engine.

It would have been entered as a 944 'prototype' had they been able to, but they weren't. Look at the 924s Le Mans history and you'll see that the '944' was the last FrontRunner entry.

Thank you Simon, very helpful []. Don't s'pose you know the actual engine displacement do you? I know it was a 16v head but,
was it a 3.0 litre or a 2.5 []?? Thanks again for your knowledge mate []!

 

[944 man]

2.5l Pete and it had balance shafts too, but other than that it was a prototype engine with little in common beyond (I think) a few dimensions. It certainly wasn't fettered a slave chain and dodgy tensioner pad...

I thought the '80 and '81 cars used the 2.0 Audi engine, but the '82 cars used a 2.5 944 engine? Someone is close to publishing a book about all this I believe, then we'll know for sure....try asking Ricky Caesar?

Anyway, highest finishing car in 1980 was 6th., a wet race but nevertheless.......

 

[CarreraRSR]

Audi engine ??!! There goes the myth again!![]

 

[T3rra]

Pete have you made much progress yet on you build? I know Patrick from Australia is selling a few bits via e bay and a complete spear Un used engine us one off them

Not really. It (a 924GTP) used a 2.5l engine which said 844 Le Mans on its twin cam cover. The cams were both driven by the belt, it had sixteen valves and it was turbocharged. It had very little in common with the 944 production car engine.

 

[os951]

Simon is correct. 924 GTP engines did not have anything to do with Audi engines. It was a true 944 engine with 16V head.

 

[Richair]

Shame that didn't make it in to production eh, but I guess the 951 was expensive enough to build and with that motor would have really pissed on the 930's chips... 944CGT anyone? That would have been yummy.

That would be a 944 Turbo Cup then

 

[Richair]

Errrrr not quite though! Turbo cup was nothing really more than a tuned up 951 for racing, not a proper 'race car for the road' special. ;-)

 

[944 man]

I disagree. It was very different and far more of a racer than a 968 Club Sport.

 

[George Elliott]

Correct Simon,

1985 launch, most cars had carbs, sorry a carb, and points, a Rover V8 still had pushrods......

951 had Motronic ECU
a Turbo with Intercooler
Knock detection
Digital Fuel Injection
Water cooled Turbo
Ceramic Exhaust Valve seats
Turbo cooling pump circuit
220 hp and later 250hp

from a compact 2.5L four cylinder with balancer shafts, made of Aluminium, with Silica for low friction and a bottom end capable of 500hp

we should not make little of it just because it had an 8v head

It was and still is bulletproof, and thats what Porsche stood for in those days, and also why many of us including myself still run one.

This is a great thread, so much is known of the Metzger Porsche engines, I am interested in the 951 because in Hans Mezgers book, he was quite vague about the 944 Lemans engine.....and I think we can all work out why...[]

But a 924CGT is just a tuned up 924 Turbo! A 924GTS was more the homologation race car and in my view on par with a 944 turbo cup

Thank you all for your excellent comments chaps []. I'm going to carry on doing a bit of research into a 2.5 litre, Turbo charged
engine with, a 16 valve, twin cam head. I would love to know what components were used to create that lovely looking engine in
Olli's photograph [8D]!! My thoughts are this; I intend buying a "Ring Card" (unlimited use) in either 2016 or 2017 as, I intend
doing quite a few visits to the Nurburgring for Touristenfharten weekends (probably one a month). I would like my 944 Turbo to be
totally re-built by then and, bomb proof! It is not going to be a trailer queen as driving there is half the fun []!! And, I don't think
you can get more bomb proof than a car that has been built to be ragged round Le Sarthe circuit for 24 hours on end with no let
up!![8D][8D]!! Now, how to find out that spec'.....[][]!

Good man !!!!

I`ve done approaching 4000 miles on track and driven there and back each time (touch wood)

Mind you, after a full day it would be nice to sit in a quiet comfy 4x4 towing the car home!!!!

Happy reading ...

That Le Mans engines block is quite close to 944 2.5L production block. Head is a forefather of all 16V (2X16 for 928's ) heads. Most of us thinks these cars/engines (944) were built from 1982, but truth is different. Factory portotype engines were running very early '80's or late '70's. After all 928 right head/cam tower run first time in mid 70's. Also first 951 engines were tested early 80's. I suppose correct year is either 1981 or '82. Prototype cars with 951 engines were used as a safety cars in few German track series during 1983 & 1984. One of these cars is at Sinsheim Technical museum http://www.technik-museum.de/
What comes to GTP engine, it's nice to see, that factory used "944" even 944 was launched... Rumor has it; factory tested 944 driveline under some other brands, just like they did it with 924 decade earlier when there was factory built Opel Manta & BMW 2002 with 924 engine, torquetube & transaxle. What comes to engine electronics IIRC 944 was the first car with Motronic. Other German brands had it years later, First BMW, then VW/Audi and MB about the same time.

Safety car with 951 engine. I took this picture 10 years ago. This safety car is interesting. Turbo front but A-model dash, winshield & brakes. 951 was planned to launhed at very late 1984. Back then there was a metal workers strike which caused lot of delays to German car manufacturers. So, 951 launch was postponed to spring 1985 and it was first shown in a car show in Sweden. First car were delivered to customers in June/July 1985.
