Heat protection plate for Weber 45 DCOE carburetor
16.02.2024
On engines with counterflow cylinder heads, which have the intake and exhaust manifolds on the same side of the cylinder head, the carburetors tend to suffer from the heat radiated by the exhaust manifold.
Especially in summer, this sometimes leads to massive warm start problems because the fuel in the carburetor evaporates when stationary and evaporates through the float chamber ventilation. The empty float chambers then cause a lot of trouble during hot starts, especially with a mechanical fuel pump.
The carburetor seals also suffer more, as do plastic parts.
This is also the case with the powerful Weber 45 DCOE, which is often used on classically tuned Volvos with B18, B20 and B30.
Like other engines from the 50-80s, the Volvo OHV also has a counterflow head and the manifold really heats up the carburetors.
We already have such a heat protection plate (1053062) in our range for the original SU HS6 twin carburetors. We also offer complete tuning packages with the Weber DCOE (1084803) for the PV, Amazon, P1800, 140 and 164.
So there was nothing more obvious than to offer a heat protection plate for these models too.
The heat protection plate for the 45 DCOE is designed for one carburetor at a time and is simply attached using the screws on the lower cover. Due to the material thickness, it is very solid and can bring a significant improvement.
In conjunction with some fan manifolds, it has to be shortened slightly on the manifold side of the B30; in our case, this was only the case with the rear carburetor.
The heat protection plate is now available in our store under the number 1091336 and is an excellent addition to the R-Sport carburetor kit.
