36-1 timing wheel

[pb3]

I am looking for a suitable timing wheel to fit the front of my Small Block Chevy V8. I require a 36-1 tooth format compatible with a VR type sensor for use with fuel injection. Does anyone know of a suitable off-the-shelf part that would fit?

See this months Performance car magazine, they are doing a feature on home built fuel injection and are using a Ford granada part, the feature mentioned the part number and I don't think it was particularly expensive.

Alternativly buy a pulley of the correct diameter from your local belt and pulley supplier and then turn it down

Yep, picked up a copy of that mag this morning, very good. But I think the pulley is too small (160mm dia), it would have to sit right at the front of my crank, past the damper and 2 belt pulley (which may be ok, the sensor bracket will be quite long though!). Also it has to be made of steel to work with a VR sensor.

John Eales sells toothed wheels and the corresponding MVR sensors for the RV8. If you're lucky it may be possible to attach the toothed wheel to your front pully. I guess you would have to fabricate a mounting bracket. I can confirm that it is quite easy to make up a manky DIY bracket, but you'll probably do a better job than I did!

Some oldish Fords, most ecu retailers ( DTA for example ), or indeed on ebay you can find various trigger wheels.

Quite a few manufacturers used the 36-1 on their engines. Perhaps you could find something in a brakers yard, as some of the Megasquirt users have done.

There's a PHer who posts in the kit car forum whose name I can't remember but has a megasquirt injected small block Chevy in his Dakar. He might be able to help, so worth doing a search on Dakar in the kit car forum.

I remember he posted following the Donington show saying he failed to turn up as planned due to too much beer, so there's another lead.

That sounds like our good man Eliot

'Tis me indeed!
Not got a 36-1 wheel on it YET, although that is an upcoming project. Fellow megasquirter Chris Good sells a variety of types on ebay. search "trigger wheel" or seller id javos-g2

Ah, this is no longer the case you can now get inductive pickups that work with almost any metal but they do need a power supply and are about 30 quid apiece, check out the RS website although steel does still work best

Don't those active sensors produce a 5v DC square wave signal rather than the AC 0v crossing of a standard VR sensor. I want to use the Ford EDIS system so will try and stick with the same sensor just to be safe. Do the sensors you mention really work with non-ferris metals?
