WTB: VGS one-piece manifold for M30 and Webers

[mmccusername]

I know-- rare!
Thanks, Michael

 

[Stevehose]

Very rare. One came up in Germany recently but was gone in an instant. Suggest doing a saved eBay search on eBay.de and eBay Kleinanzeigen. They came in 1 piece and 3 piece.

Thanks. I've got searches set up, but my saved searches on ebay.de seem to work even less well than on US Ebay.
Hoping someone here might be hoarding one. Definitely looking for a one piece.

I know Steve has one and likes it, but what is the advantage to the VGS over the Korman manifold (says a guy who has a Korman manifold)?

It clears the thermostat housing and the brake booster.

As the guy who bought one from Germany in an instant, I can tell you it is still on my shelf - long from being installed on my car. I am not 100% certain I will use it - I am at about 70% probability. And for me, it also depends on applicability of finding another option (a Korman manifold for example). My current Redline manifolds are clearing the t-stat housing, so I think we found a good housing. And I have a tii booster that I am considering using, which alleviates that clearance issue.

I don't know what my point is - just rambling...

I thought your point was going to be that you were going to sell me your VGS manifold!

Yes, well, I guess based on my rambling there is a solid 30% chance of that. Let me ponder my alternatives. Feel free to PM me (with the offer I can't refuse).

In my opinion, if you don’t have to use the VGS manifold, I would use another. I’m sure that @Stevehose can elaborate, but the depth of the carbs aren’t in alignment. So things like bolt on air boxes and other filters can be trickier. The things is that if you don’t use that manifold then you need to worry about the t-stat and the booster.

I personally like the idea of a one piece manfold, but for me that is still just a concept. I haven’t proven that I can bolt the whole thing to the head with the carbs connected and throttle balanced. It works on my bench but I have access to the studs.[/QUOTE]

Is there a picture of the VGS manifold? I am way behind the curve on this.
Thanks

Not the depth, but the spacing, they aren't even because of the first carb t-stat clearance. It was available with an airbox with brake booster cutout. Not as cool as Alpina, but VGS was another engine tweaker back in the day and still in business.

That’s pretty cool. Thanks for clarifying!

Getting the washers and nuts on the bottom studs will be the hard part because you will have a hard time seeing what you are doing with the carbs in place. The front three are not too bad, but you will probably will need to remove the expansion tank to get at the back three. And you will need swivel sockets to tighten.

 

[Stevehose]

I've taken the entire carb & manifold assembly off the head in one piece a couple times. I have a special ground down 13mm wrench I use for a couple of the hard to reach nuts as Chris mentions. And a couple different socket extensions.

 

[Markos]

I see this as a big advantage of the one-piece manifold. Would you agree or is it no big deal?

Not necessarily, I removed them with the manifold to check that the accel pumps are in synch and to avoid splitting the carbs from the manifold because the gaskets I use in between them are difficult to clean off and is a miserable task to replace. Otherwise there isn't a big need to be able to to take them on and off often, if you do that means you have other problems!

Great photos Thanks !

That looks to be a better design than most available at this time.

Does that fact that the carbs sit further away from the engine ( and more air around the runners) help the fuel stay a little cooler ?

 

[Ohmess]

I would think the effect on fuel temps of moving the carbs either closer or a little bit further away from the engine would be negligible. An air box drawing air from behind the right front headlight would have more effect, but it wouldn't look as good and worse yet the induction sound would be muffled.

i wonder nobody talks about torque with the Webers.... when we installed them , we went from 300 NM ( oem injection) to 240 NM! ( HP was the same , 210 )
With long inlet tubes and airbox we got that 300 NM back. So it may sound great , but torque loss is pitty.
