The Mazda Canada PDF says "TBA" for HP and torque, but a Mazda insider who posts regularly on the forum says the 3.7 gets 278HP and 263LB/FT of torque. Great numbers if you ask me!

15 more horses than the 3.5 is not so good I was thinking something like 300 like Cadillac is getting from their 3.6 but im no engineer
:D

^^ Could be a lot of things
- preliminary ratings - iirc both the Fusion/Milan's 3.0 & the 3.5 were first quoted lower #'s
- tuned more for MPG
- tuned for a flatter torque curve (if not particularly high)
- simply detuned slightly so Lincoln can have a higher # ...
tho if it has the same tune as the 3.5, it'd only come to 280hp (280.14286 to be picky ;-)

now I'm thinking the rumors I've seen that the Mazda6 is getting it too, are more likely
& really makes me think the Milan should get the 3.5!!!! That'd give a nice progression imho:
Fusion PIP3.0 & GTDI4
Milan PIP3.0 & 3.5
Mz6 3.7
MKZ 3.7DI (with direct injection, 300 should be no prob)

But if I remember right Cadillac 3.6 is DI and this 3.7 numbers are NA so maybe we will see higher numbers for Lincoln since the 3.7 is supposed to be DI

Guys, keep something in mind. This only thing "official" by now is the confirmation that there is going to be a Duratec 37. TBA is the official word regarding HP and Torque.

Great news in any case.

Also keep in mind that dual variability to cam control is another feature that could be added at any time. Not just DI.

Its an improvement, and it will help make Lincolns different from their Ford and Mercury cousins. Does anybody know if Ford is planning on making a V-6 bigger than the 3.7?

Don't be sorry. This is a Duractec thread in the Breaking News section. All predictions are much welcomed. I hope your will end up becoming true.

2b2, I really like the idea of the black 3 bar grille with the chrome stip on top. Looks sharp.

Simple displacement calculations of 265hp/3.5L yields about 75.7hp/liter and if you scale it to 3.7L it should be about 280HP.

I have heard that Ford/Lincoln versions will have much more power, but the Mazda version may not have the same features, so.....

But remember Lincoln 3.7 will be the Twin Force DI so that means it will go north of 300hp I say they should give Mercury the NA 3.7 and Ford the 3.5 that way you can have some difference between brands in hp

^^ ummm no, the TwinForce is 3.5
I think* the 3.7 is bored out
& they use the 3.5 for turbocharging since it'll have thicker cylinder walls for better durability


* tho today has been particularly difficult for me in re-assessing reality :-(

^ I read somewhere that the MKS is going to be introduced with the 3.7NA and then is going to get DI and Turbocharging and I dont think putting the turbo in the 3.7 will do any damage since the Engine can be bored to 4.0

Boring and stroking might get you to 4.0L, but the 3.5L is better for TT. Good for over 400HP anyway, or 350 conservatively.

Another attribute to note here is how durable the basic 3.5L was designed to be so as to allow for future HP capability of around 400HP. It just inspires more confidence than a motor that is already near it's peak.

this is true, i think one thing the American manufactuers are doing is to be cautious of the ratings before an official sae test can be dont, ...remember Honda and Toyota and their low low hp ratings? The previous generation Camry went from a respectable 220 hp in the V6 to 190 after sae was done with them.:o

... since the Engine can be bored to 4.0
I have asked this question of various engineers inside the company and have been told that the current block can not be bored or stroked beyond the current 3.7L displacement. They could add more deck height to get to 4.0L, but there are no plans.

I know this is supposed to be a 3.7L thread, but you shouldn't overlook the base 3.5L features as compared to the 3.0L.

Besides the "obvious improvements" (more power, better fuel economy) there were 2 very important design goals:

Lower cost to manufacture
Can be used in both FWD and RWD vehicles with little change

The first lead to the elimination of the roller finger followers and the hydraulic lash adjusters, a huge cost savings. This also make the engine lower and narrower.

The second put the water pump back on the "front" of the engine, which also saved money by eliminating the unusual drive mechanism on the rear of the head.

When will we find DI in the D35 and D37? Hopefully winter of next year?

No plans for a 3.7L DI (a.k.a. EcoBoost).

The 3.5L EcoBoost should show up in the MKS in "early spring" of 2009.

The 2010MY Taurus has a Job #1 of March 2009. The 3.5L EcoBoost will be available in that vehicle also, I just don't know if it will be there at Job #1.

DAMB sucks compared to RFF with HLA.

DAMB sucks compared to RFF with HLA.
Care to explain that statement ?

I believe that both Mercedes and BMW use DAMB. It is also widely used in 4 stroke motorcycle and outboard engines.
