Howdy Coupers,

Wanted to asked the "Triple Weber" crowd here if they'd be kind enough to share images of their installation with me. I have a set & manifolds ready and heard of 'different solutions' regarding linkage and brake booster issues. I'd like to do a some 'visual' research if possible before I take the conversion on as a possible Winter project.

Images from both sides of the engine would be great.

Any "triple carby' E9s or E3s gonna be around for the Monterey Fests? Still trying to figure out if i can get down there that weekend.

TIA-

that is NOT a triple weber setup -- that is a work of art!

well done!

I parked next to Richard at the Vintage at the Vineyards. It is even more impressive in person. I kept my hood closed in shame.

I'll trade you my webers for your paintjob and interior...

Thanks for the compliments.
 
Thx for the replies fellas.

Bimmerboy: is that the 1 pc Korman manifold with the std Redline triple Weber linkage?

Keep 'em coming gang! This might be a good topic for the Documentation gallery.

Thx.

yes and yes

Word of advice... see if you can get something other than the redline linkage kit. Its not the highest quality. Dont want to bash it or anything because its been fine so far... i just dont have the highest confidence in the precision, execution and fitment of the parts. They may make something a notch higher, i'm not sure... Its working fine for me right now but i'm looking into upgrading when i have the time, money and energy to take it all apart and do it over again. I've seen pictures of another kit... beefier arms, higher quality adjustment screws, etc. but am not sure who makes it. Didnt take the time to research a whole lot after i got them on because i was just happy that they were reasonably set up and that the car ran :). But the honeymoon is over now, so i'll be looking again soon. The other option that my mechanic (and 2002 guru) keeps pushing on me is a cable linkage that you can either mount above or below the carbs ( havent checked the clearances below to confirm that it would fit). Above would be fine except it tends to clutter the carbs some (to me anyway). He claims its much more precise and easier to adjust...

Food for thought...

Also, get a good plan together for rerouting your coolant lines as well as your fuel and brake vac. Some claim that you can squeeze the webers in with the stock booster. In my experience... no way they would have fit... just was not physically possible. But one thing i did notice this weekend at the PVGP when looking at J Jacobs' car was that the booster on his coupe was considerably thinner (front to back, not diameter) than mine. Not sure why... My booster was a good 10" or so front to back. Have pics that i can send to you...

Also... if you go with the tii booster, you may have to fab a connection from the brake pedal stem to the booster stem (i'm sure there's a technical term for these pieces, just dont know what that is). Anyway, i have pics of what i rigged together that i can share as well if you run into issues. IIRC, the stem from the e9 booster threads into the back side of the booster and is connected via a bolt/pin to the brake pedal. However, the stem from the TII booster does not have a threaded hole to receive a stem. Instead, it has a short, forked end. So i had to fab an opposing forked connector that i was able to thread onto the e9 stem to get the 2 to connect (basically cut an aluminum turnbuckle in half, drilled a hole through both fork ends, matched the e9 and tii forks/holes up and bolted them together). My brakes havent failed yet so i guess its working ok :wink: .

And one more thing... you'll probably need to modify your thermostat housing so that the large outlet is angled up and away from the engine(toward the radiator). Otherwise, you wont be able to get the hose on because the stock location will be to close to the carbs on cyl. 1 and 2

Almost forgot. If you do get the redline linkage kit, count on buying a dremel too as you'll probably have to shave off some of the metal on the pivoting linkage arm ends (the little do-dads that thread in and out to extend or shorten the length and have the ball ends - my brain is fried right now... drawing a blank). Anyway, the way they are designed, they'll interfere with the throttle arms at about the 50% open point (or about 45 degrees) preventing full open throttle. Specifically, you have to trim the side facing the throttle arm.

If all of the above hasnt been enough to deter you... then you are probably certifiable. But i guess all that means is that you fit the profile of the typical e9 owner. You'll probably have plenty of folks trying to steer you in the way of FI or 38's. - Dont bother calling Carl N for advice either cuz he'll give you an earful... at least he did to me for about a solid 15 minutes when i was trying to get his thoughts on what to do with the distributor vac. lines :). My advice... push on. And when you get into it and it looks like there's no hope, have a beer.. or 6, take a nap and then get back to it. Its well worth the reward if you can stand the smell of petrol ALL THE TIME and accept your fuel economy being measured in fpg (feet per gallon) rather than mpg.

I'm sure that there are a few more members with triples that can chime in as well...

Oh... JAM Engineering is an EXCELLENT source of info on all things weber. Ask for John - i think thats his name.. its been a while.

Thx Richard-

Advise noted. Itsa a pandora's box of a conversion, yes, but my motor (Alpina 300 cam and oversized valves) seem to be calling for the triples. My motor currently runs the 38s, they work great until 5k rpm. Then seem to starve a bit.

My bros racer runs triple 45s and he's got a beefier link set-up that was custom. His tech/guru had the same thoughts about the Redline set-up and went another direction, not sure if I/he can replicate it hence my query here.

thanks again and still curious to see other Coupers' triple set-ups!

-TIA

Would anyone be upset if I posted my triple webers off my Australian Built Xu1.............it just shows a very very solid linkage set up that was made for me by a firm in Brisbane Australia who are specialists in Weber triples. I found the redline stuff to be B grade and hard to keep in tune with stretching and slipping etc and I have a spare set up for anyone who is willing to ask for my redline cast offs......they simply dont last. In this photo the long rod is stainless and the short arms are anodised alloy billet and the adjustment rods are made from hex bronze solid. There is probably better, but this is just soooo solid. The redline set I used to have fitted , had pressed adjustment arms etc that sort of compression clamped onto the long common rod.........Yes I know it is not a BMW, but it is my other work in progress. Cheers

 
sorry, an xu1 is a car made by gm out here in oztralia in 1973, it was factory fitted with triple strombergs and for race applications it used webers. I have two of them in various states of resto.

cheers
