This is great news Geo 1-2-spark pnp for Visa even more excited now

Boggy

Hi boys

just a note

i visited Geo last week

Barking mad ( loads of cars like all of us)
but a very smart engineer and loads of thought gone into the new 1 2 system

had a look at 1 2 spark and am very impressed
so much that i will fit several to the 4x4's and do long term tests

I will manufacture a new mounting for the sensor

A laser cut plate to allow for easier fitting of the sensor etc

and In co operation with him hope to go forwards with this project as i see it as a great improvement over
previous ideas!

this gets my Best New product Award 2013!!

Thanks mister Pony, now you got me blushing

Sensor Bolt.

I plan to drill and tap a bolt into the (thin) Flywheel, in the same orientation as the 8 deg Static timing hole.

Question.
Has anybody done this in the flywheel..... in situ?

Cheers
Peter

I've done a heavy flywheel in situ - I marked the flywheel with small drill at correct point and then turned the flywheel to get at it on the bottom (more room down there). Then drilled and taped. Used thread lock and non stainless bolt.

@ChrisW
I thought is was you that had done a drill/tap set up, but couldn't find the post.
But see pic to clarify...

A doddle off the car

Hi Pete,
No mine was on the outside edge, I think one of our friends from Holland has done like you want on the back/front.

SubPete what we do is drill at the small side of the flywheel, because you don't need to take the flywheel out of the car....

But you can do it like your showing at the picture..... but be aware you must have space enough to place the sensor, it is a littlebit crowded where you planning the sensor (carb, inletmanifold and so on).. and be sure that when the pickup is at the sensor the engine needs to be 45 degrees before top dead centre..... (try to keep it between 45 and 42 degrees)....and it will be fine...

A second thought of mine is when you have axial play at your crankshaft the flywheel can move to far away from the sensor but then we are talking about a play of more then 0,5 mm... so keep the sensor really tide to the pickup to avoid this problem.... (I've seen crankshafts with more then 1.5rmm play) but ofcours yours hasn't..... (does it)....

Point Noted on Crankshaft end float? Will check?

Thinking out loud.
Aluminuim Block to hold sensor bolted to the flat area see picture

Also on the other side of the engine, there is also a larger flat area on the web, above the oil filter, the barrel on that side further forward.

Yep looks good to me but check if coolingplates?? exhaust/heatexchange are not in the way, or is exhaust running away to the opposite side, I'm a little dizzy with your car
