Re: Drysumping
half crank speed is normal for the Titan pump Ove.
Camshaft is half crank speed... OK.
However, if you run the pump off the cam at the gearbox end it may be too high in the engine bay to work properly. The hose to the pressure stage from the tank should be gravity-fed not sucking thru a height (where the pump is higher than the tank). The scavenge system also may not work if the scav stages have to suck the oil 2 ft above the sump..

Re: Drysumping
The Titan 30T pulley is 3/8" pitch trapezoidal (rectangular teeth).
It will accept industrial or automotive pitch - auto 3/8" pitch is stronger but if you use a 3/4" wide drive belt either will do. There are more lengths of belt available in industrial than automotive.
If you run off the cam you need to work out a position for the pump so that you can be sure to find a belt of the right length. It is a good idea to use a tensioner. The drive pulley from the cam should have flanges front and rear so the belt stays in place.
In the photo the drive pulley has only one flange (there is not enough room for two flanges) but there is a flange on the rear of the tensioner pulley.
It is easier to use a tensioner than to try and mount the pump in the 'perfect' position to get the belt tight.
I can help with belts & pulleys etc if you need me..

Re: Drysumping
Ove I can get any pulley made you want but for cam drive you need 1:1 drive
good for 9500rpm engine speed...
30 cam - 30 pump

Re: Drysumping
sorry my mistake - the standard series 2 Titan pump has 22 teeth not 30
I have two types of drive pulley - see photo - with 22T
Both are designed to run at 1/2 crank speed - One has two flanges, the other has one flange with a tensioner with rear flange. The pulley cost (of either type) is £90 + mailing.
It would be much more to make one single pulley (& design time) so if you use one of these it would be better..
