Welcome to the new look VWWatercooled
After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.
Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before.
We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

Yeah Branko has a good point. They've squashed a 6 cylinder engine into a hatch engine bay..so there has to be repercussions. It still goes great, and would go nicely in a mk2 because it's light and will drive it real easy, but at the end of the day nothing that VW produces like the R or VR motors will be in the same league as american engines.
I agree that they don't design them very well (just because I reckon they slap massive things together because ''bigger is better'' in the US) but my my they produce some power for straights...Mrk Detailing, premium automotive detailing. Paint correction/protection specialist. PM me

not your average american muscle v8 - 32 valves guys. how many yank engines have 4 valves per cylinder?
impressive. not my cup of tea
from wikipedia - http://en.wikipedia.org/wiki/Northstar_engine_series
The Northstar's design was initiated as a response to the advanced dual overhead cam V8 engines introduced by European and Japanese competitors of Cadillac in the late 1980s. At that time, Cadillac was using the aluminum HT Overhead Valve (OHV) V8 which had been pushed hastily into production after the failure of the V8-6-4 of 1981.
Cadillac was developing new models like the Allanté and updated Eldorado and Seville STS which they hoped would compete against the best from BMW, Mercedes-Benz, Lexus, and Infiniti. They developed a laundry list of items that must be included in these new models, including sophisticated steering, braking, and suspension technologies, which became known as the Northstar System. One key element was a high-tech V8 engine with all of the features and performance of the competitors' offerings.
The "Northstar" V8, as it was then known, was an evolution of the Lotus-designed Chevrolet LT5 all-aluminum DOHC 32-valve V8 used in the Corvette ZR-1. Archrival Ford Motor Company was developing a similar engine at that time as well, and Ford's Modular engine would precede the Northstar into production with its introduction on the 1991 Lincoln Town Car. Both continue in production at 4.6 L of displacement.
Capable of producing 300 hp (224 kW), the Northstar featured a cast aluminum 90° V8 block with 102 mm (4 in) bore spacing split into unitary upper and lower halves. The lower crankcase assembly supported the crankshaft without conventional main bearing caps. An oil manifold plate with an integrated silicon gasket forms the oil gallery under this. A typical oil change used 7.5-8 quarts of oil.
Cast-iron cylinder liners were specified and the forged aluminum pistons included valve clearance, making Northstar a non-interference engine, with bronze pin bushings and free-floating piston pins used.
Cast aluminum cylinder heads were used featuring 4 valves per cylinder. The heads used dual overhead cams which are driven through the "maintenance-free" cam-drive chain case. The cams act directly on hydraulic lifters on the ends of the valves and are fed with a lubrication passage drilled through the cylinder head lengthwise. The intake valves are inclined at 25°, while the exhaust valves are canted to 7° with center-mounted platinum-tipped spark plugs. The cam covers were fabricated from magnesium for light weight.
Eight thermoplastic tubes were used in the induction system, leading to sequential fuel injection. The engine uses a direct ignition system with a single coil per cylinder and no distributor. The PCM controls spark and fuel injection timing as well as the shift points for the new 4T80-E transmission.
One notable feature, advertised at the time, was the fail-safe cooling mode which allowed the engine to continue running for a limited time without any coolant at all. It alternated banks of cylinders, basically "air cooling" the inside of the cylinders, to maintain cool temperatures, allowing a Northstar-equipped car to be driven with no coolant for about 100 mi (161 km) with no damage.
Another unusual feature of some Northstar-equipped cars is a liquid-cooled alternator used on Cadillac's Seville, DeVille, and Eldorado. The liquid-cooling helped prolong the life of the alternator in these electronic-laden models, though GM reverted to a traditional air-cooled setup for 2001 to eliminate potential leak points and extraneous tubing.
All engines of this family share the same Northstar bellhousing pattern.
Later developments included variable valve timing, which can vary intake by up to 40° and the exhaust by up to 50°. This system was devised for the longitudinal LH2 version, and has not, to date, been used on the transverse front wheel drive engines due to packaging considerations.Last edited by gldgti; 25-08-2009, 05:23 PM.'07 Touareg V6 TDI with air suspension

Took me a while to spot the radiator : )
"There isn't room for a fan under the hood, so I had to mount one in the front between the bumper and the rad. It's a pusher fan and is a high flow unit. No cooling problems whatsoever!!"http://www.cardomain.com/id/sydvr6

Can't think of too many examples off the top of my head, but none of those corner very well - compared to other cars made by different people, for eg audi's or lamborghini's or honda's for that matter. That's all I was getting atas I said they produce some mighty power but it's only really good for pissing contests (read: drags/straights) so to speak hehehe.

Mickey, I swear sometimes you just pull stuff out of thin air. You said "bigger is better" so would assume you were referring to the displacement of engines.
Anyhoo, if you're talking about handling, the Viper is one of the quickest production vehicles around Nürburgring - so it must handle pretty well. You can't really compare a Lamborghini to a Mustang - maybe to a Ford GT - which would out-handle pretty much anything Lambo has to throw at it. Then you have the likes of the Corvette and even Cadillacs that handle extremely well considering their (your) philosophy of "bigger is better".
I was particularly talking about engines anyway.
I'm not saying they make the best cars in the world, although some are definitely up there. It just pinches a nerve when "enthusiasts" (I use the term very lightly) make outlandish claims based on... I have no idea. Being one-eyed maybe? Chinese whispers from other "enthusiasts"?2000 Mk IV GTI
