2 barrell carburetor - Land Rovers Only

tonkatoy189 · 05-13-2007, 10:00 AM

Looking for a little more power. I have a single barrell Webber 341CH now. I've seen pictures of 2.25s with 2 barrell Webbers on them. Redline dosn't list this conversion on their site. Does anyone know about these? What intake manifold is used? And most important of all.... Is it worth the price?
Also, how about simply changing to a K&N air filter over the oil bath air filter? any power gain there?
thanks

The K&N filter will become a huge depate....

Don't really know too much about the 2 barrel carbs, but I would not think that you would get that much more power out them. You have to remember that you have a 2.25L engine with 68 horsepower. There are tuned heads, modified cam shafts and the sort, but they will never give you modern day horsepower (nor is the truck designed for that..) Why are you looking for more power and for which situations?

I had a 36/32 DGV Weber 2 barrel on a Brel rebuilt motor that had a Turner HP head on it a number of years ago. No matter what I tried, I could never get the carb adjusted. It always ran too rich. Gas mileage was attrocious and I even had problems with the carb icing over on damp, chilly mornings. From the standpoint of performance, what little, and I mean little I gained in the way of horsepower was lost on 10 mpg economy. In the end I bought a new Zenith, swapped intakes and learned to love the slow lane of life.

Oh, and when I had the 36/32 on the truck I also had a special Pierce heated intake to help with the icing. I also had a set of Clifford headers and a K&N air filter. I was always uncomfortable with the K&N sitting up there on top of the carb because I never felt it was adequately protected from water and mud. I even went so far as to use the K&N foam around the filter for added protection.

I know there are others who have had different experiences with that Weber and I also know that the carb that was on the early 110's and 90's was a better choice (34 DTML IIRC) so it really comes down to trying it to see if it fits your driving style.

mostly I'm just curious. I put one of these carbs on my old toyota and it helped a bit especially off road. I know a larger carb won't perform miricles. Was looking for others experience. I have other priorities for the rover before carb stuff anyway.
thanks

Dunno about the 32/36, but when I swapped out my 34ICH for a rochester, it was like someone strapped a solid rocket booster to my rear crossmember.

Look into one of those first. It was a cheap and easy upgrade.

I concour about how finicky the 32/36 is. Got one on the formula ford. Damn thing is a nightmare.

I heard that to get much benefit from the 32/36, you should run the 2.5 cam and headers. My friend has this combo in his 88" and he dynoed at 56 wheel HP at 7400' elevation(9:1 head also) My tired .060 over 9:1, header, 32/34DMTL only got 42 hp. I had a stock cam. Pierce can tell you exactly what jets to run if you tell them where you are and how your truck is set up. BTW, we both get about 20 MPG.
