Mystery camshafts - Vegantune VJ3 details?

I recently bought a rebuilt Europa block and head that had been prepared for someone to use in an S3. Cam cover and timing cases changed to suit.

It’s for a +2 but there are more visitors to this discussion forum

It appears to have been well prepared, still has build grease on everything, but the camshafts are proving tricky to identify.

They started as the original single groove C type S/E spec, then have had Vulcan VL107 stamped at oil plug end. It was originally thought they were L2 spec.

The base circles are approx. 1" 24mm on the inlet and 25mm on the exhaust with a lift of around 9mm on inlet and exhaust. I only have a basic caliper(not a Vernier)

The clearances are 4-6 thou on inlet and 9-10 on exhaust.

I tried Vulcan but unknown to them.

On further disassembly yesterday, to determine the cam follower size (5.5-6mm) I found the inlet cam had 420 etched on the face, under the Vulcan vernier sprockets, but it looks as if then etched over and a clearer VJ3 etched along side it.

Has anyone got the specs./details for a Vegantune VJ3 camshaft please?

Can’t find any detail on the Internet other than comments on this forum about VJ5s. I was about to get some other C types reprofiled to 360 profile but these may be OK as may be similar - they’re for normal road use.

I haven’t got a DTI or timing disc to check anything further but James at J W engines proving to be very helpful I might add.

I’m just looking for any details someone might have or experience of VJ3s specifically as a starting point.

Kind regards

Chris

Measure lift and duration above the base circle. If you cant do that take it to someone who can. This will give you the basic data to determine if they are usable for your intended service.

Chris,

It may be my Vegantune VJ5 thread you are referring to. I finally went with new cams to QED420 profile.

I concluded that trying to reverse engineer cams from a company that folded decades ago just wasn’t worth the effort. Unless the engine had some sort of provenance that you were trying to preserve, better to go with a known profile and known results that engine builders and tuners are familiar with.

Andy.
