I need some info about the LET's "nockenwelle", because I now have 2 different values for the exhaust valve opening time.
What I have:
Serie LET:
Ausl. => open 60 v UT, closed 28 n OT, 8,5 mm hub ???
or => open 54 v UT, closed 28 n OT, 8,5 mm hub ???
Einl. => open 14 v OT, closed 68 n UT, 8,5 mm hub
Anyone have the right LET exhaust timing for me??
The opening time of 60 v UT seems wrong, and is the same value of an XE cam:
XE:
Ausl. =>open 60 v UT, closed 32 n OT, 9,5 mm hub
Einl. => open 20 v OT, closed 72 n UT, 9,5 mm hub
Reason I ask is that I want to use XE inlet cam together with the standard LET exhaust cam.
When I look to the diagram in the R-LET article, it is wise to close the exhaust valve a little earlier to minimize backflow by higher boostpressures. (= exhaust manifold pressure...). Turning the standard LET-cam a few degrees earlier might do the trick here!
Thx for any info. (Auf Deutsch is O.K.)
