VR6 tacho counts 3 pulses, 16V counts 2. Your best bet would be to use a generic rpm generator. I can't remember the brand but Stealth Racing sell them. You just tap into the coil signal wire for cyl 1 and the rpm box does the rest. The output of which you send to your clocks. I think there's dipswitches on it to set the signal count for a 4 or 6 cyl. Stealth will know more. A few of us have used them successfully on R32 conversions where the original clocks use CAN BUS for the rpm signal.

Definitely! If the old 80s 6 series wings cost a fortune, I hate to think how much body panels for your Uncle's cost! A pristine car like that would really stand out in today's sea of samey cars. I love the 8 series as well but I'm not brave enough to take one on! 911s are like driving a chunk of granite on wheels. Mega strong body shells! And yep, certainly with the older 911s, the whole car fizzes with feedback.

You guys are making me blush :oops: :D It's just my ramblings really, and I do a lot spannering and reading :study: I'm glad forums are just areas for the exchange of opinions and ideas, because I'm sure loads of engineers and engine builders would probably challenge me on half of that, but the it's the basic principals :) I'm not suggesting people shouldn't mess with their intake systems though. Some people like the noise and aren't bothered about optimal running. I'm too picky and like everything to run perfectly!

I didn't notice any "ewwwwww" comments, but I know old Bimmers aren't for everybody :D That's a lovely Bimmer! I just love the build quality of them. Not necessarily the perceived quality of the interior, or the engines, but the Unibody. No creaks from the door frame going up kerbs and uneven roads from any of my Bimmers, unlike the Corrado and practically all Golfs. Not even the Tourers with no sheet steel behind the rear seats. BMW just seem to make really strong monocoques. Porsche do as well :D Of the post 2001 BMWs, the only ones that interest me are the Z3M coupe, the E39 M5 and the 1M. The rest are all meh.

Easiest way to analogise the Helmholtz theory is the sound you hear when blowing across a glass bottle top. The noise you hear is a pressure differential. Same as the buffeting you get from sunroofs at low speed. The roar you hear from a VR6 is basically air waves being bounced back to the airbox, so if you remove the resonator tube, or swiss cheese the bottom half, you hear it very clearly! I think a lot of people only consider the intake system to be downstream of the throttle. Everything upstream (i.e MAF, pipes and airbox) is all fair game for mucking about with. Some people even take the air straighteners out of the MAF because they consider them to be a restriction! The ONLY way to increase MAF flow is to use a larger diameter housing. When VW design intake systems, it's end to end, and there are actually 2 tuning tubes in the aibox. A small one where the air enters the bottom half, and the resonator tube in the top half. The entire intake system is a very carefully designed compromise between packaging and intake tuning. The air waves are contained. The whole idea of intake tuning is you want the air wave that's bounced away from the valves, to push new air in as it bounces back. If you've stuck a cone on the end of your MAF, or butchered the air box, you lose that effect. I should should add that this effect is most noticeable at low to medium revs at part throttle. When the throttle is wide open, all the engine cares about is getting max air in, so peak hp numbers don't really change, but low and mid throttle response generally suffers.

I've had 3 of those bad boys. 2 x 1990 325i tourers and 1 x 1987 325i coupe. Lovely machines. I could still get parts for the D reg one. I find BMW dealers less snobby than VAG (Audi especially) too. I never did get around to owning a 325i Sport in Dolphin grey with the recaros, they were lovely cars back in the day. The 325i motor is way torquier than the VR6 low down as well. All old school Bimmers have a charm to them. Not so keen on the modern stuff.

Ah the good old snorkel, or 'Helmholtz resonator' to give it it's proper name :) It's job is to adjust the pitch of the intake sound and aid cylinder filling, but people just chuck it in the bin, thinking VW put it there for fun. When mine was a daily, and standard, there was a noticeable drop in bottom end response from removing the snorkel, but nobody ever tells you that. All you hear is "Whoo hoo, it sounds awesome". Yeah, for about day, and then it gets bloody irritating. The BMC is the only filter I've personally seen make a tangible difference to power and isn't obnoxiously loud. As for a standard VR6 not sounding like a VR6, just press the throttle down more at lower revs to get the engine working harder. Cams can indeed alter the pitch of the intake noise. Some subtly, some very noticeably. Depends how the changed profiles bounce intake pulses back to the airbox. K&Ns don't filter anywhere near as effectively as the standard paper, but the dirt they let through is usually small enough to pass through the intake valves without harming anything.

I know what you mean. I loved the power band of my VRT engine, but just fell out of love with the car it was in. A Corrado VR6 can barely make the most of it's standard power, let alone twice that, such is the ancientness of it's underpinnings. Good luck with the M5. I'm not saying any more about them :D

Got any DSG gearboxes?

It's a legendary thread that started off as a query about Angel Eyes, and then quickly devolved into one mega pile of off topicness! It's really old though. Not sure if it came over with the new forum or not.

It's all a load of internal politics dog shat. They all use TPS anyway. If you get friendly with an Audi dealer, they can and will get VW parts in for you. Neil's being doing that for me for years :D TPS are shat though. Parts acquired by them regularly arrive broken or the wrong part picked. Moron f'cks.

You could always create another 'Angel Eyes' thread if you're bored :D

You'll want the Corrado back after a year with an M5. Check for rust on the rear arches and evidence of big ends being checked / replaced.

Seems very reasonable to me.

My stuff from Germany has always arrived in 3 days via DHL. Ditto with Fedex from the United States of American land. But I ordered a pair of running shoes from Addidas's UK site. 6 days!

Yeah the VR6 is very picky with lambdas. Back in the day I tried a cheap bosch replacement (for OBD1) from GSF and it ran like shyte. Bought a genuine one and normal service resumed. I had the OBD2 sensor with my conversion anyway, but I remember asking Vincent if OBD1 and 2 are the same (coz I'm curious about these things) and he said OBD2 definitely different / better. I believed him! The lambda doesn't kick in until 70 ish deg water temp, so you can move it around no probs.

In a nutshell, some cars make very little extra power, some make about 20 extra hp and some 30 extra, but the average is around 210hp. Back in the day, you'd be lucky to get 215-220hp from the big 3 (Schrick 268, VGI & big throttle). Schimmel cams really are the jelly. Just don't use uprated springs with them as the iron quality is not as good as VW's / Schrick's.

He took one for the team :lol:

Seriously? Dude, OBD2 uses a different sensor, hence the different plug. Please don't tell me you are trying to fudge and OBD1 lambda onto OBD2?!?!? Get the proper OBD2 sensor. Consider yourself scolded :D Seriously mate, Vince told me ages ago when I did my conversion that OBD2 uses a much better / quicker responding sensor.

That would make a VR6 feel a lot quicker than standard, but gearboxes are over looked as a path to performance in this country. Nice kits :)

The last sentence was aimed at the OP :)

Why are you picking pins out of the sensor plug?

Agreed on the search being schitt on here. 263 as a search term should bring back loads of results, but it returns absolutely nothing. Search for "263 cams" and you do get results. Bag o shyte.

It will and there will be absolutely no acceleration when you go to over take either, necessitating a drop down to 4th. Completely pointless imo, unless of course cruising and overtaking sedately are a priority :) Is the cost and hassle of changing gearboxes really worth it for chasing a few more mpg?!
