The inlet profile is called Z10 its a bmw sport profile, and the exhaust is M20 from the BMW m20 engine apparently, he also separated the lobes as much as possible, actual valve lift is 9,3mm inlet and 10,2 exhaust (don't quote me) I don't have the build figures here. Havn't bothered measuring duration and such, set it up so that inlet valve on #1 has 1,4mm of lift at TDC.
Enem is a well respected and trustworthy company, so I just let him chose the profiles to my useage area.
I told him we were looking for 200bhp +/-20 a useable powerband from 4000-7000rpm, ported head, T25, intercooler and around 1bar of boost... I also sent him your reccomendation and this is what he sent back, all reground and tuftrided... if you want to pick hs brians now or in the future he is easy to deal with, just look up ENEM in sweden, the guy to talk to is Jan Carnebourn.
Fitting the engine today, so late tonight or tomorrow we should get a tune out of it.
Conk.
