What are my cam gear settings?

[EnricoPalazzo]

I recently installed my adjustable cam gear, and got it tuned. I was not happy with the service i was given, and when the tuner was dialing it in, he told me that 1 notch is 1 degree. Is this rite? I was told by many sau guys that 1 notch on the cam gear is equal to 2 degrees crank. anyway when i was told this i instanly started to worry.

So ill get to the point. Lookin at the cam gears on the engine, ie straight ahead, the exh cam gear is 2-3 notches to tdc. Now does this equate to 2-3 degrees? or 4-6 degrees?

Cheers, ill try post a pic, but my camera is dodge and doesnt pic up little details too well.

Thanks

What brand of cam gear is it??

My first thought would be 2-3 marks (notches) would be 4-6 degrees.

I know the Greddy and the HKS ones are like this (the greddy one actually said it in the instructions).

I think someone mentioned that 4 degrees was about 1.9mm movement.

Greddy / Tomei 1 inotch = 2 degree, not sure others..

Also the direction the cam gear is set to, is it advance of retard?

Ill post a dodgy pic

Yepp, that looks right.

The motor turns in a clockwise direction when your looking at the front of the motor.

So looking at the picture you can see that the cam is trailing (retard) the cam gear/belt.

It's hard to say, but the amount it is moved by looks about right for 4 degrees retarded.

Dean, pretty sure mine is set 4 notches back for 4 degrees (from memory), its a HKS one. yours looks advanced to me. If its retarded, the internal part of the gear should be rotated to the left, so the cam is set back from the center factory setting. By moving it to the right, it means the centre is forward, or advanced.

[Steve]

To make it a bit clearer, the lobe centre should be moved back (left), in your diagram it appears forward.

[EnricoPalazzo]

so it is wrong? Do u think i can do a dyno run on sat, then change it to correct 4deg then do another dyno run? Obviously ill do all the labour myself so wont bother shaun at all?/

[EnricoPalazzo]

the lobe center is to the left isnt it? Look it doesnt really matter, on sat i will take of the cam cover and the we all can have a really close look at it. Ok?

[Steve]

no probs. If you get in early on sat, I am sure shaun wouldnt mind looking after you. He's very reasonable.

It is retarded. The pulley turns clockwise, and the cam that is attached is now lagging slightly behind the pulley, so everything happens just a bit later.

The pulley has 48 teeth which is 720 crankshaft degrees. Each tooth on the belt is fifteen crank degrees. If you look you will see it has been retarded about one third of a tooth. Pretty close to four degrees I would say.
