Well, keep in mind that part of the reason for the cam profiles is fuel efficiency. I would imagine to maintain the fuel efficiency numbers, Honda would maintain to some level the i-VTEC system, though it might be configured a bit differently to be optimized for the turbo.

TinkySD

Right -- for peak power it's definitey the way to go, I just don't know how well the switchover works with a turbo... would you lose boost in that split second where the cam changes over? It's probably quick enough to make no noticeable difference but I'm not sure how much more complex the engine/management software will have to be to account for it and if honda would consider it to be cost effective as opposed to just using slightly better turbo technologies like a twin scroll system.

The rule of thumb I've heard with CR(might be oudated now with the use of continuously variable timing -- it might be more now) is a full point of CR = a 4-5% increase in toque and hp.

Hate to spoil the party but I think you guys may be getting just a tad ahead of yourselves here.

TinkySD

Honda is going to have to have these technolgies available soon. Toyota is going to have it's direct injections in models starting next year starting with the new GS and IS and making it's way through the rest of the lineup. They are already availalbe in Japan as far as i know.

TSXforme

So true...a few German manufacturers are already using this technology in their vehicles. It's just a matter of time when the Japanese manufacturers are going to use this technology as well.

dom

I was reffering to the Turbo.

TinkySD

I don't care what you were reffering too, it's my job to disagree with you.

But you're right, even a 12:1 2.4 liter would be cranking some pretty serious torque figures.(as well as increased gas mileage)

sauceman

with Tinky. Plus, I don't think Honda, as a top engine manufacturer can afford to let themselves be run over in the tech department by other engine builders for very long.

Eeyore

Rest assured, Honda will NOT let themselves be run over by anyone in the tech department. Their 4-cyl engines are the best in the world and I'm sure they a) know it and b) plan to keep it that way. They sometimes take a bit of time to get something "new" out there, but when it hits, it usually kills the competition with its combination of fuel economy/power/refinement/reliability.

Eeyore

So an Acura killed a Honda and now a Honda is going to be responsible for killing an Acura. Sounds like poetic justice. I'm not so sure the Civic SI will be responsible for the end of the RSX. The only way they can pull it off is if they add at least one more low-end model to the Acura lineup (already planned with the RDX), and keep the TSX below $30k. Very aggressive marketing of the Civic SI will also be needed, IMO.

But the top and largest engine manfactuer in the world doesn't even build a V8, V10 or V12. And Inline 6 would be nice too.

sauceman

The fact that they don't use V8, V10 and V12 technology for the civil car market doesn't mean they don't have the technology.

If they are the #1 engine manufacturer in the world, they must do a lot more than just build car engines and small engines.

dom

Well, they are the LARGEST engine manufactuer in the world. I guess #1 depends on your definition.

And no, all they do is build car and small engines, unless I'm missing something

Well, ya, but its still a small engine. All I'm saying is thats it strange that the largest and IMO best engine maker in the world doesn't build a V8. Lets not get into why again since this has been beaten to death.

Hopefully they've seen the light and will launch that 2.2L turbo.

sauceman

Well they do build V8, V10 and did build V12s for racing purposes. Which is why I'm saying they do have the technology. Just that they choose not to use it in civil applications.

Dan Martin

A 3L V10 would be a nice match for a TSX I think.

sauceman

Problem is, and BMW is experiencing it, if you want to sell your V10 as being an offshoot of F1 technology, well that technology is now outdated.

The technical requirements move so fast as of late in F1, that the manufacturers can't really benefit as much from the image as they could if Max Mosley and friends weren't constantly improvising.

Why then would Honda sport a F1-bred V10? Would it be worth the risk with a V8?

Dan Martin

I don't want a watered down V10, just give me the 900hp @ 19,000 rpm model.

dom

They don't count

What frustrates me about Honda and I think most would agree, is that like you said, they have the technology and know how to build a V8, V10 or inline 6 but also build it BETTER than anyone elses'. And anyone who says they don't need a V8 should take their head out of the sand or out of their asses and look at the MDX, Pilot, Ridgeline and RL.

Thats what so exciting about this rumoured 2.2L Turbo. You just know it will be the best Turbo motor of similar size on the planet.

Dan Martin

They've been rumored to be working on a V8 for quite some time. I think it would be a very good move but I don't know if we'll ever see it.

sauceman

Guess I gotta say to that.

I left it out purposely as its probly toast anyway.

Well, the problem is the business model. Honda has to come up with a business model for developing a consumer V8 engine and provide a solid case for it. Because Honda's only market where a V8 would be actually appreciated is the US, Honda doesn't see it as being a good business case to develop at V8 motor.

Now, though, since the competition is introducing V8 motors into all markets, Honda has to change in order to remain competitive and Honda now has platforms that could benefit more from a V8, which is why there are rumors floating around of a Honda V8 for a new ultra-luxury model to compete against the S-class and 7-series.

TinkySD

I6 motors are extremely overrated IMO! They are smooth but are a packaging terror. They are heavy and tall. This is the reasons bmw isn't able to put a larger i6 in their cars. instead, to try and stay competitive they have to put all sort of technology into their motors, valvetronics, throttleless induction, electric motors for everything etc. While I"m a big fan of technology this makes them expensive. Plus, the new high output 255 hp 3.0 liter will still not able to out run a g35 which costs many thousands less.

Precision Crafted

That V8 could also be used in the MDX, Ridgeline, Pilot, and next gen RL. As was posted prior, I am not counting the NSX as it is most likely dead.

05_TSX_GP

To me the only real cool thing about I6 is that it is a physically natrually balanced configuration... and that's about it. Having said that, I continue to admire innovations from BMW (its their R&D $$$ to spend) to improve its I6 engines (the new line in 6er and upcoming E90 has got some really cool stuff). But I much rather drive a finely built Honda 4-banger that can be rev'ed so damn hard and still be so reliable.

sauceman

I'd love to see an exotic I-8. Dry sump it, whatever, who cares. That would be a beauty...

Sorry, just kinda nostalgic from the last time I heard this engine.

ClutchPerformer

But the irony is that if they put a V8 in it and got, oh let's say 4/3 of the HP or ~380HP, it MIGHT not be so toasty anymore...
