Any in this community know what elements of the Jaguar 3.0L Duratec give it the increased power over the Mazda6S Duratec?

Well, the X-Type is rated at 7 greater and the S-Type at 15 greater. First off, both have greater compression ratios of 10.5:1 compared to our 10:1. The horsepower difference is so small it could be due to any number of little things, but most likely it's just the breathing - intake/exhaust - in addition to the CR increase.

Not to mention increased timing, so you gotta run 91+ octain. The heads are designed different too. Plus it wouln't make scense for the Mazda car to outrun the Jag would it You could probably get the same amount of HP the Jag has with some simple mods.

tune the 6 for 91-93 octane, it will get us right there with the jag.

mmarfan - the part about it doesn't make any sense that the Mazda should make any more power over the Jag is not entirely true. Consider that the Licoln LS V-6 makes 232 hp 5 more than the x-tpye yet the Jag costs more, is more prestegious yet offers less from the perspective of performance. It really depends where the OEM places the priority. Mazda did a far more better job of taking a humble duratec engine and breathing a soul into the vehicle for the driving enthusiast and offers better performance than the x-type. Did I mention that Mazda did this for less money (roughly $10K less). Mazda is focused and appears to have found their way back to their nieche. Jaguar is stilll floundering around trying to determine what they are going to be while in the meantime they keep on turning out compromised products that cannot stand on their own two feet with their competion. Even Volvo produces much more gratifying performance vehicles than Jaguar for less money. The S60R base MSRP starts at $36K and offers AWD, 300hp, 6-speed manual, and unparalled levels of safety. A Jag x-type for more money can't event touch it.

NoBull6, thanks for the details. I was under the impression (don't know why) that the Jag version was putting out either 240 or 270. Your numbers and the contributing factors make perfect sense.

The Lincoln and Jag 3.0s both use a 3-stage intake manifold, ours is a 2-stage. The valves on the L&J 3.0 are also different sized than ours, we have the same sized valves as past 3.0s.

The X-types are heavy weighing about 300 lbs more than the 6s.

Well I would swap it out for the new duratec 35 block if it can bolt up to the MZ6s 3.0 heads.

I own both cars. The 6s DOES outrun the Jag 3.0. Not by much. But with both cars stock, the 6 is the winner.

Yep,

According to Car and Driver, the V6 manual will outrun the Jag 3.0 manual at any speed.
C&D:

M6 0-60 mph:6.8
Jag 3.0 AWD: 7.1
Lexus IS300:7.3
BMW 325i: 7.0
BMW 330i Sports Package: 6.4
BMW 330i Performance Package: 5.9
Acura TL: 5.9
A4 3.0: 7.5

VERY surpised to see the A4 as the slowest! Knew the 6S ATX was about dead on with the IS300 ATX from personal experience in an impromtu acceleration comparison from a stop up to about 80mph.

I am not surprised at all that the A4 is the slowest. Those things arent quick at all. Also the Acura TL is not a manual, I think it is a manual-matic type of a tranny, but not a manual.

All those AWD cars are porkers thats why. If they make an M6 AWD, we're looking at 3400lbs or more. It'll be a porker too and they'll need to bump the HP to make it competitive.

Are we V6ers going to have an Intake-Manifold upgrade? is that even worth an aftermarket company making?

I thought the 240HP Honda Accord V6 got most of its bumped up power(from ~200HP) due to it's "racing inspired" intake manifold. Its essentially the same V6 they had been using though, from everything I read.

Unless it's an '04 TL which is available with a 6 speed MT.

I have got to belive that Mazda will do something to bump the HP for the 2005 model year. Honda did great things with that V6 of theirs....

I had thought those test numbers were for the auto as the 6 speed has not been tested as of yet.

I believe they will too...so many people give into the peak hp rating at the crankshaft rather than the wheels.

thats the real reason why there is so much restriction built it...just design a more free flowing airbox/resonator and volia another 5HP.


also, they can always bore out the cylinders just like Nissan
