Trigger Wheels
Turbo Mini Forums

I have been busy at work and knocked up a few trigger wheels, not wanting to tread on Mr Fentons toes but these are much simpler than a machined ppulley, simply bolt on the same as triggerwheels.com

stats are :

135mm OD
50mm clearance hole for socket
5mm MS

10X15mm holes to cut weight

2X5mm holes for M5

335g in weight

36-1 tooth





as for price, not really sure.. how does £16 posted take peoples fancy ?

when a mate fitted his one, it was very simple, drill and tap 2 holes.. no real complexity to it, with yours its sending at away to be machined..

they are 2 completely different things, obviously the machined pulley is the best option, this is just the easier "at home" method that i can see

How can that ever be central without some serious measuring equipment? just for impartiality I don't like the idea of machining a damper either lol!

I stand corrected. You should know

If like me you machine the outer edge of the damper then fit a trigger ring so that the teeth only protrude half their hight above the outer diameter of the damper, you are pretty much adding almost the same weight you machined off. Its not exact, but it has to be close.

What I do not understand with these trigger wheels is why have the extra mass of the middle section when its fixed near the outer edge? Also, I'd like to have seen at least three fixing holes. As others have said, it might prove time consuming to centralise on the pulley.

I have never being keen on ether method, but it has to be done. 3 fixing points would be nice, also a CAD template printed on card showing you where to drill could be a nice addition?

Also, this is nothing like the trigger wheels version designed for the A series...

Look under 'engie specific trigger wheel kits'

In the 13's at last!.. Just

I can appiciate what your saying, but with a vernier it really isn't that hard to get running decent enough, a mate has fitted one using nothing but a steel rule with no problems, looking at the trigger wheels its 40quid, I will add another hole for mounting today..

Anything else peolle would like to see?

Is the large centre hole the same dimention as the pulley hole?

if so it should be straightforward to fit.

If they are the same diameter, a tube to locate the two during fitment would make it a piece of piss (if you get what I mean)

I understand what you mean, thinking on your toes, like it.. from memory its just 50mm to clear the socket, will measure a pulley and can adapt the wheel to fit.

Possibly supply a piece of the correct diameter tube to aid fitting of the trigger wheel

Yep thats where mine is.. I don't think it will fit with a belt drive kit tho. It screws to the tapped holes already in the pulley..

IMO - easy fit for me would be a bolt-on and no messing to then set it up for tdc..

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

Just lasered out new design with 3 mounting points, to do this the 15mm holes have now become 11mm to stay on same pcd

Would it be easier if the 3 mounting holes were elongated holes following the circumference of it, maybe 10mm long each.

Just to allow it to be easier to set tdc ?

Any feedback welcome,

Schrödinger's cat - so which one am I ???

I would say elongated would be helpful

So have you made anymore that are for sale yet? as I need one asap

Unless you plan to use the center hole to aid mounting, why not just leave 5-10mm inside the mounting holes and chop the rest out?
