I want to install DC20 cams in my 2,7 rs, but i can't find the overlap settings.

I hope someone have some info on this.

On John's site there are no DC20 listed with 104 lobe center.

Thanks

His name is camgrinder here on Pelican. Send him a PM and he should give you an answer.

dc20

I have sent camgrinder a pm but no answer.

I really need to find the settings now.
With a lobe center of 104, it must be special grinding.
Can I use the degree scale to find settings? Or set inlet and exhaust even when overlap?
Some who have suggestions?

Thanks

Or Google "Dougherty DC20" and a number of Pelican posts come up that have your answer. Tried posting the links yesterday but didn't get them past the moderator!

DC20 cams

Just a little late feed back.

Thanks to John Camgrinder for providing the correct specifications.

I would set these up at 3.4mm.
These cams are more aggressive vs. the 911 E.
Fall between the solex and 911 S profiles.
248/236 @ 1mm with .470 / .450 "valve lift.
104 lobe separation angle.

I was busy getting the engine done. The car should drive historic hill climb and the engine in the car was 3.2 and not allowed. I thought the car would be slower with 500 cc less a comp. ratio 2 points lower. But no, the little 2.7 is much livelier from 5000 rpm and 20 kg less.

The car won 7 hill climbs in 2017 and became champion in Denmark in historical class.

That is a Fine looking car Daugaard. I'm also really happy with cams John did for me. Great performance and holding up just fine (no pitting etc).
