Turbo cam?? N/A cam?? - pmj4147 - 01-31-2014
I heard
"N/A cam has more lift than Turbo cam"
but i could find the information just for 605/606
My question is a.............. It's same with 602/603??
More lift than Turbo cam???
RE: Turbo cam?? N/A cam?? - sassparilla_kid - 01-31-2014
I would expect n/a cams to have longer intake duration but I could be mistaken, as I'm not an engineer
RE: Turbo cam?? N/A cam?? - barrote - 01-31-2014
hello fine people ,
i´m about to check that, cause i have to rebuild a head from a 2 damaged one is N/A the other is T , so i let u know that , but u may start thinking that valve lift is the same , timing no , will be diff , timing in N/A engines must consider some valve overlap to deal with cylinder filling and dinamics of the exaust. on the other way turbo versions want to empty the cylinder as fast as possible to fill it under boost. so u may expect diff timing instead of diff valve lift.
i´ll post my fidings later

NA exhaust cam on the 605 606. No clue on the 603.
RE: Turbo cam?? N/A cam?? - mantahead - 02-04-2014
yea, om606 n/a intake cam had about 1.4mm more lift than the turbo intake cam, exhaust cams where the same.
some info here, http://www.superturbodiesel.com/std/Thread-OM606-NA-CAMS-V-TURBO-CAMS&highlight=na+cam
sorry, no info on om603.

Thanks for correcting me! I have a 603 turbo cam on my wall of shame I can measure. We never got the 603 NA here, anyone have one on hand?

RE: Turbo cam?? N/A cam?? - barrote - 02-05-2014

The BMW guys (petrol/e85) usually drives with a modified intake cam on the exhaust side. Is there a difference there to on the om605/606 engines. So two N/A intake cams on a OM-engine might be awesome. If it's doable that is.
RE: Turbo cam?? N/A cam?? - winmutt - 02-05-2014
So ya, my comment about exhaust was based on BSR's new videos for their budget std. He said NA for the exhaust, makes sense that it would be an NA intake. Is the profile the same? Never seen cams on the 605/6.
RE: Turbo cam?? N/A cam?? - mantahead - 02-05-2014
ah rite, i was wondering about why the guy on the BSR video said they where using n/a exhaust cam with 1mm more lift.
he must have meant inlet cam.
as Erling pointed out in that other thread about cams, you can't run inlet cam on exhaust side because they run in opposite directions, off the gear, valves will be opening in wrong order.
