Topic: weber carb adapter

[RN37DD]

weber 32/36 carb.. got a choice of two adapters .. one is two piece with one hole.. the other is one piece with two holes. is one better than the other??? I'm useing it on a 20r manifold and head that well go on a 22r block..

i used a  2 piece  adapter  with my weber

Story around the campfire is that the 2 piece adapters have a tendency to develop leaks. I've got the 2 piece and so far it's been working fine for me, BUT it isn't the most "polished" adapter and I can definitely see it causing some people problems. I was unaware that there was a 1 piece adapter, but if there is I'd hit it up.

last time i looked Lcengineering sells adapters.. the one piece came from redline weber but i believe you have to buy the whole carb kit to get it..  I have a two piece I'm running on a worn out 20r that hits redline all the time 5500rpm+ and I haven't cracked it yet. but i see how it could be done pretty easy if the bolts got overtightened..

i GOTS THE TWO PIECE  one on mine, works fine I did match the adpter to the intake and cut out the center "web".

[RN37DD [OP]]

yeah i was wondering about removeing that center section. seem like the intake air would just ram right into it. I had to grind the plates to get it to fit. even the one piece looks like it needs to be cleaned up to fit right.

trans dapt has a nice one piece i have it on my toyota the only thing you have to do is put a spacer in between your intake and throttle linkage

[RN37DD [OP]]

yeah the trans-dapt adapter looks pretty good.. How dose it work??? I also couldn't find the $$ on them..

[kneedownnate]

The air won't ram into the center piece because it matches the bores on the carb.  I took mine and matched it both to the carb and intake manifold gaskets and ended up with very little in the middle but still some.  Can't tell you what the benefit was because the engine blew up directly after that.

Edit:  I take that back.  I matched the manifold to the adapter, had it backward in my head.  I do think I cleaned out any ridges in the adapter though.

[RN37DD [OP]]

doing the same..leave center alone.. match adapter with manifold. hope 20/22r dont blow up !!! est 2 weeks till install.

[kneedownnate]

Good luck with it!  I coulda swore I took pics of the cleaned up inside of the adapter, but what I remember doing was just removing the little ridges and rounding the edges so there were no steps for air to run into.  Just tried making the carb/adapter/manifold transition as smooth as possible.

heres the other adapter i have on the 20r ive been trying to blow up for over a year. It won't die. just seems to run better and only acts up when people are watching.

[brainlessfool]

That's the one I have, that's why I cut the center out.

Story around the campfire is that the 2 piece adapters have a tendency to develop leaks

 


And when it creates a vacuum leak the truck will run for 1-5 minutes and die. Only way you can keep it running is keeping your foot on the gas. I ripped my hair out and contemplated selling my truck because I couldn't find the leak. Replaced the manifold gasket like five times and even had a propane bottle hooked to a release valve so I could find the leak.  Such a PITA....
