Default Opening and closing times of JUN Cams

Hi all

I am trying to find some information on a set of JUN cams.

The only numbers I can find on the cams are F002 on the inlet F102 on the exhaust. On both cams there is the number 018. I believe they are these cams JUN AUTO - JUN HIGH LIFT CAMSHAFTS and Kit - SUBARU EJ20

We believe they are the 9.5mm lift, 264 cams. Would anyone be able to tell me what the opening and closing times of these cams so I can dial them in properly?

Cheers

I'll do some digging Geoff. The Forester driving chap that came to our pizza night could shed some light.
James has his number. See you tomorrow.

Nothing you can't work out with a degree wheel and a dial gauge.

How do you work out the opening and closing time this is adjustable with wheels.

The cam is 264 Duration , but when will it open and close and at what lift is this taken .020 usually OEM or .030" some american stuff but they usually go lobe center or .040 as the most used lift
Any way I have some cosworth 277 by 11mm lift that in need info on so watching with interest to how to work out the open and closing times

Sorry for the confusion. I want the opening and closing degrees at 1mm lift.

See image of the Kelford timing card. The values I'm after are the "timing @ 1mm valve lift".

Ah - the image came up fine on Tapatalk. Thanks man.

So I emailed JUN and got a reply!

INLET Center angle is 110 degrees
EXHAUST center angle is 115 Degrees

Quick test of the engine before dialing up the cams and I was at 102 degrees inlet lobe center, so I was considerably out.
