Trigger wheel fitting help ?
Has anyone fitted a trigger wheel to a sprint , the trigger ring /wheel I can see to fit will only be bolted onto the outer flexi part of the wheel and would leave it not totally accurate for a crank sensor , has anyone fitted one for ignition type change to such as megajolt
Cheers

I welded mine on the inside of the pulley. It worked fine and is still going strong afaik.

I can see them cheers , I see your set at 90deg before tdc (something I wasn’t 100% as I’ve not done this before ) also like the bracket looks a tidy spot to mount 
Re: Trigger wheel fitting help ?
I'm just in the process of fitted EDIS on one of my 1500s, just waiting for the trigger wheel to be made and fitted to the pulley
Some people are like Slinky's, they serve no real purpose in life but bring a smile to your face when you push them down the stairs.

Hi Martin,
If I remember right, you were running this set up on your Sprint with twin 45s. I just wondered what TPS you used. There is not much clearance at the front of that manifold as the thermostat housing gets in the way.

Hi Andrew. I was given a TPS from a Ford Mondeo, I believe (not that you'll find one of those over there). It's just a 3 wire sensor. I fabricated a mounting bracket and cobbled something together to attach it to the left-hand carb throttle spindle (nearest the bulkhead/fire wall).
