Talk:Detroit Diesel Series 149

149 Cessation

As a DDRE employee, I can assure you that the 149 is most definitely still in production. I see a fellow make brand new heads for these every day from 6 - 2

"naturally aspirated" is incorrect

The introductory section refers to the 12V149 and 16V149 as being naturally aspirated. This is incorrect, as the 149 series are two-stroke engines they require forced induction, and the base models, like other two-stroke Detroits, have Roots blowers. Probably should copy the section from the series 71 article that talks about uniflow scavenging into this article. — Preceding unsigned comment added by 69.180.123.64 (talk) 23:52, 27 April 2014 (UTC)

Are RD-350's naturally aspirated or not ? Detroit itself calls them "NA" for "naturally aspirated." All the blower does is scavenge the crankcase, similar to what gasoilne two-strokes do by pumping outside air through the transfer ports on the piston's downstroke. That's not "supercharged." 116.231.79.159 (talk) 11:50, 8 October 2017 (UTC)

Two allegations of material inaccuracies in this WP:OR article tells me it needs to go.
