305HP Pentastar V6

http://www.pentastars.com/


Quote:
The Pentastar engines were created by Chrysler engineers to replace the V6 powerplants used by both Chrysler Corporation and Mercedes. In 2011, it will become the sole V6 option in ten vehicles. In 2012, it is expected to be Chryslerís sole V6.

The first Pentastar was the 3.6 liter V6 engine, pumping out 305 horsepower and 268 lb-ft of torque in the 2011 Dodge Challenger. 90% of torque is available from 1,800 to 6,360 rpm.

The forthcoming direct-injection 3-liter twin-turbo version is projected to hit 420 horsepower, enough for Maserati.

This site has rumors and projections for the future, an in-depth look at the Pentastar V6, engine specifications, and a look at production and the factory.

WTF??? Why would the wranglers be tuned for less power than the WK2? Also, I'm hoping for direct injection, which should increase power...

Theres no need to increase the power by direct injection...its possible, so id turbo or super charging.

WK 290HP 5100lbs
JK 280HP 4200lbs

I am sure cold air intake/exhaust will help..maybe even a tune.

Yep. It's quite nice too.

I got news for ya though - it's not going to be much of an improvement over the 3.8, if any at all. All of this non-sense about how the 3.8L sucks and this new Pentastar is the greatest thing ever. No. It's not. I drive the GC and then get in my JK with 37's and 4.10's and the furthest thing from my mind is "goddamn I wish I had that 3.6."

Besides, the JK's been getting a new motor for almost three years now. Bet it doesn't happen again this time either.

Oh, and the 3.6 has a weird ass oil filter.

well. it still wont do me any good.

2010 Challenger with a 250hp 3.5
2007 JK-U with a pukey 3.8... i wont even bother with a rating.

i'd wonder why they would bother derating the engine from model to model. you'd figure that cooling and intake would be plenty sufficient to handle it across the board.

oh well..

The biggest improvement will be a 5 speed transmission or even a 6 speed DSG.

3.8 237 Ft Tq
3.6 256 Ft Tq

See not a huge difference! The transmission will be what makes the new JK worth it.

The weight isn't a good reason in my book. Why derate it? I don't care if the jk only weighed 1500 lbs. The motor is the same so leave it alone. The only way that would be acceptable is if its retuned for more torque.

Was thinking about getting a second JK this summer, but if that's really going to be available for 2012 I'll hold out instead of buying a 2011.

It makes a huge difference and 10hp does not matter much. Its all in tuning so it would be easy to get back.

Any one read about the 3.5 liter that ford is fixing to put out. 365 hp with over 400 ft lbs of torque. And they are slapping a 11,300 pound tow rating with it in their trucks! I would do that swap in a heart beat!!!


Oh and no I am not really a Ford guy but damn,,,they got this engine right!

Huh? The JK has been getting a new engine IN 2012 for almost three years now.

Just curious, what's weird about the filter, a drop-in canister or something else?

You know what I meant. First it was 2010, then 2011, now 2012. I call BS.

Yea the oil filter...small, open element, drop in style, on top of the motor. Picked up two at the dealer last Friday.

All of Chryslers V6's are getting replaced, from what I see in 2012 the wrangler and the truck will be the only non Pentastar in the line up. Clearly 2012 is the year of the 3.6 and others to join the group like a new 3.0 v6 as well. The Ford F150 ecoboost is direct injected which boost big power yet efficiency.

I'm still not totally sold on direct gas injection yet. I think it has a while to go till its totaly refined. I'm hearing about a lot of issues with large deposits on the intake valves and problems with fuel dilution in the oil. Some are ofcourse worse than others, but I don't think its been perfected yet.

Yeah, maybe Chrysler should work on perfecting a V6 that doesn't blow at 40K before they tackle direct injection.

On another note, whether or not the JK gets it, this new V6 better have more than 300 HP if they want to stay competitive. Chevy, Ford, Nissan (just off the top of my head, probably others as well) all have naturally aspirated V6's that make more than 300 HP.

Then they'd have to make the tranny, drive shafts, and axles stronger

The current Pentastar does not have direct injection, Ford and Chevy does. So imagine if the Pentastar did have direct injection....266HP 406t tq?

But if you look at the meat of chryslers line up that engine is perfect. It's the jeep line that is going to eat it.

I think this thing is finally coming together. Still Needed: drive shafts, frame mount rails...then done son! For a while...

The Pentastar will be better than the I-6 and the 3.8 as far as power is concerned.
