For all people who are interested in LET cam-timing, there is an interresting article here:
Look under downloads => Rally LET article.
Yes, I know it's in German, and it's probabl;y posted before, but still the in- & exhaust pressure diagrams are very interresting!! (and look at that downpipe!)
Another subject: any people here who have problems with exhaust "valve-float" due to exessive exhaust pressure with phase 3.x?? (prevents exh-valve to exactly follow camlobe, pumps up hydro lifter so exh-valve stays open.....)
Some German LET's have this, and is cured there with small shims under exhaust springs.
Any more thoughts on LET camtiming?
