Aluminum Billet Throttle Unit: Gas valve diameter 80mm Outer diameter and hose connection 90mm Total length of the 90mm hose connection 45mm (25 20mm welding allowance or a favorite area for the hose) (You can shorten this if you want) The center-to-center hole spacing of the intake manifold flange bolt is 77x77mm, so it fits directly into the Volvo B200-B230 intake manifold sold in the online store without inertia work. However, it comes with a 14mm aluminum body plate flange facing the intake manifold with a 77x77mm thread gap, which can be welded to any intake manifold directly if necessary, if you do not use this spray suction kit sold in our online store. In the picture, this approx. 14mm thick adapter flange is screwed to the gas valve with 6mm x 4 hex screws. The throttle shaft fits directly to the Bosch std sensor (standard output is 8mm diameter), but you can change the adapter to the shaft and you also have to turn the throttle shaft adapter to the right position by removing the small hex screw, etc. When the throttle is fully open, there is a throttle 7mm outside the aluminum flange (14mm), which must be taken into account if necessary Pressure-sealed self-lubricating bearings for both 10- and 12mm shafts can also be changed, however, it must be taken into account that air can leak through the shaft bearings through these closed bearings. If necessary, a groove can be made in the gas shaft, and an O-ring can be placed in the groove for sealing. However, this solution stiffens the turning of the throttle and the challenge is to make the throttle and pedal sensitive when high boost pressures are used, e.g. over 3bar boost pressure. (This applies to turbo and compressor engines)
