VW 2.1 100HP Info Required

[PeterH]

LRP or 50/50 LRP AVGAS should be fine on the V-Dub
The timing runs fine at 25 - 28 degrees with a locked distrbutor or with mechanical advance loose at 25 - 28 degees at 3000 rpm.
Above specs of timing on Aerovee 2.1 , Great Planes 2.1 both with electronic pickup on flywheel.
Same timiming specs on 2.1 and 2.3 V-Dub from Arno van Wyk.
Try this it works on BB ZU-ASL with 2.3 owned by Brian Coetzer in BFN and BB with 2.1 owned by Pieter Swart in De Aar.

Agreed, the only reason I retard the timing is because of the turbo. Used to run my 2.1 Revmaster on a 50/50 mix as well at 26 degrees.

I messed up 2 VW engines with Mogas. Go Avgas and save yourself a lot of trouble!

See Stephan van Tonder's informed opinion on the previous page. I flew a VW type 4 on Unleaded
and valves went. The engine was repaired and flew after that with Avgas only and it has since done
many hours with new owner trouble free.

Most engines can run unleaded fine IF the valve seat is made from the correct grade Stainless steel.

Made sure I had those when I built my engine Anyway, that is why LRP was introduced.
