Description Weber 4 x 44IDF performance kit for Rover V8 3.5 / 3.9 Webcon has offered a Weber manifold for the Rover V8 engine for some time, but with two carburettors positioned on each cylinder head this has sometimes proved a little too high for some applications. Now Webcon has revised the design and positioned four Weber IDF carburettors in a line along the the manifold between the heads, much like the early Aston Martin V8, creating an overall lower profile. The height of the assembly from the top of the intake port to the top flange of the carburettors is 150mm. The stock air horns are 63mm giving an overall height of 206mm. This can be reduced by 40mm by using 16mm air horns and low profile emulsion tube holders Suitable Mesh Air Filters The 44IDFs in the kit are supplied with the following “starting point” calibration which will allow the engine to start and run. Venturi 36mm Auxilliary venturi 4.5 Main jet 135 Air corrector 175 Emulsion tube F11 Idle jet 50 Pump jet 50 To achieve maximum power, driveability and efficiency, we recommend that you have the carburettors calibrated on a rolling road. Please note that, owing to our policy of continuous improvement, kit contents may be subject to change without prior notice. JDA-PRV403
