Did you mention a Hemi?

I know you will all hate me for this, but I've just got to post it.

Go to this site:

It will blow you away with Hemi enginuity! Sorry for posting it... Just had to! If I find any more of these, I'll post them in the lounge! Just this one... I couldn't resist!

LOL, yeah, that was all in Hot Rod magazine a while back, pretty cool stuff.

I did some research and it turns out that it's the result of a contest held back in 2005. But the content of the web page is pretty sweet.

I've been posting questions about the MDS system in the DODGE Hemi's and I went online looking for some supporting material when I found this article. I feel it important that I quote something from there, to help save your MDS engine in the Dodge vehicles.

Oil grades and use. If you have the MDS system, be sure to use 5W20 oil - note that many dealers will use bulk 10W30 or even 10W40, partly out of ignorance and partly because it’s cheaper. You need to use the right oil if you want to keep your engine. Of course if the owner’s manual says something else, follow its advice - but don’t be convinced by a mechanic or oil-change place. Insist on the right grade and if they don’t use it...get a refund and go somewhere else. A technical service bulletin (TSB) - 09-015-04 and 09-013-04 - says: “Vehicles with the Multiple Displacement System must use SAE 5W-20 oil. Failure to do so may result in improper operation of the MDS.” Watch the mechanic pour it in! (This is the real reason BMW provides free oil changes.)

Anyhow, I thought it pretty important as I found many other resources that mention the same thing. I think the quote is for year 2005 + hemi's. If I find different recommendations, I'll post them. But for now, the above quote seems an important note, especially for those who run vehicles in the Winter and run heavier weight oil normally.

Also, another interesting quote from Chrysler:

Chrysler announced on June 21, 2007: “For 2009, Chrysler Group [sic] will deliver a significantly upgraded version of its renowned 5.7-liter HEMI V-8, resulting in notable gains in fuel efficiency, refinement, power and torque.” They also announced that the Phoenix V6 would get MDS. The gains are expected to come via variable cam timing, according to always-accurate oh20.

Redriderbob had correctly predicted in May 2007: Chrysler will be debut a revamped Multi Displacement System (MDS) on most of its V6 and V8 lineup by the year 2010. They have been working on a new updated MDS system that will debut on the 2009 Dodge Ram 1500 models. After its debut, it will be featured on the full V8 lineup (except SRT). Most of the V6 engines in Chrysler’s arsenal will also feature MDS.

oh20 also said we can expect three 5.7 Hemis in 2009; the variable-cam edition should be around 380 hp. At the same time, a 6.4 liter Hemi is expected to get nearly 500 hp. He also said that the 6.1 Hemi (SRT version) might get MDS in 2009 or 2010.

Sounds like Hemi's are going through some serious re-engineering in the upcomming year! For those of you who are currently dis-appointed with your MDS system, you either will love or hate the idea of all future DODGE vehicles having them! I'm sure the improvements will also pre-empt performance chip manufacturers to actually write coding that utilizes/optimizes the MDS rather than ignoring or disabling it.
