Yeah, the air-cooling... How did you manage to cool the sensors?

I used an old cowling from a disc-brake: It follows the curve of the bellhousing nicely. I bent it open slightly around each sensor and welded an L-shape bracket to it, to attach it to the head/barrel shrouds rear/inner screw. (It's original brackets were already broken off). The top is held in place by a bracket under the r/h starter motor bolt. I also welded a plate to the front of it, that reaches the engine casing, to sheild it from any heat from around the outside of the head/barrel shroud. It is fed cool air from the fan cowling via a plastic tube, in the same way that it would have been on a disc brake model. (Mine is on large drum-brakes, as it's a 1968 AK350). It can quickly be removed if necessary by just loosening one bolt and one screw. When it's in place, you can feel the cool air escaping out of the top end of the cowling, having passed the two sensors. Obviously the faster the fan turns (or the faster the vehicle is moving), the more cool air passes through the cowling.

Thanks guys, for advertising my product.. I'm still working (in secret) at a real plug and play solution for Visa/LNA using the Original Visa sensor-holes and a replecement sensor. But still without a for me acceptable result.
But it is true, you can always make a pickup at the flywheel and put the sensor mounting a bracket at the upper hole on the engine yes theres already made a tappered hole in the engine).... There are about 8 or 10 Visa engines running this way as far as I know and as said befor some are running only on 1-2-Spark....


p.s. Love your solution for cooling the sensors. Could never believe it makes such a diffrence cooling them......

Dammed I wished I had a plug and play solution for Visa/LNA.......

Did you already test with the Mercedes/Chrysler sensor? Although still not really plug and play, i think it should just be long enough reach the original flywheel pin.

Thanks chevrons2! With your permission I'm going to try to make sth similar on my engine and will tell you about the result on the road.
