hye just wondering like on websites n so on it lists the 3.2 TL as a sohc but arent there 2 heads on a v6 so one would assume there are two cams for the two heads reason im asking is bcuz this guy is saying tl's are dohc yes inform ME im a noob

 

No just like accord v6s, TLS are "sadly" Single Cam as well...would've been great if dey were Dual...*SIGH* would've ripped even more..

 

Is that a fact?

 

definitly not dual. single overhead cams on our TL's.

 

SOHC on all J-series motors. Sure, there are two banks, therefore two heads, but that's not the way it's done.

 

i remember reading there are certain benefits of SOHC over DOHC... more power coming from the DOHC engine. ofcourse the NSX is DOHC.


but i heard the parts are more expensive/harder to replace for the DOHC engine.

 

That's mostly why the J-series was chosen to be SOHC. The J-series engine is used widely throughout the Honda/Acura line-up, from the Odyssey minivan, MDX, to sport sedans. Most people don't even know what SOHC and DOHC stand for, much less about what they actually do. So it was wiser for Honda to choose the more cost-effective route while sacrficing a bit of performance, and perhaps even efficiency. But the bottom line is that our SOHC engine isn't exactly lackluster, either. It performs great even with SOHC. What we lose from lack of DOHC, compared to other Honda engines, we make up in displacement.

 

I completely agree with Pure Adrenaline. you can make just as much power on a SOHC than a DOHC. i think what you were looking for it this SOHC means Single overhead cam. our TLs are SOHC due to only one cam in each head. DOHC s have two cams per head. so the NSX has total of 4 cams. thus the larger head on the block in the c-series. the main benefit of the DOHCs is the adjustabilities of the tuning. you can finer tune a DOHC than a SOHC. cause you can control the exhaust and intake valves. on a SOHC you pretty much control it all in one cam. so the adjustabilities are a little easier on a DOHC. so our 3.2s are SOHC due to the single cam in each head. but SOHCs do make power and as Pure Adrenaline said we make up the power in displacement. no replacement for displacement!!!

 

not true. dohc is much better at making power. it has much better control over the cams, and cam timing, valves can be placed better due to having 2 cams as opposed to 1 (on each head) as for cost? i dont buy it. if honda really wanted to make it affordable they could. look at nissan. all there VQ's are dohc

 

when they say SOHC OR DOHC, companies mean per head, like te TL as 1 cam per head, it would be confusing if a car had 4 total cams, and u sayd quad over head cam, then people whould think 4 cams in 1 head?!??!

 

its per head. thats how its rated 2 per head DOHC, 1 per head SOHC. 1 cam in the block OHV

 

hey....if there was a head from a motor that was dohc and could be swaped with ours....could we change ours to dohc?

 

but mercedes makes amazing power with sohc,ex:C55 AMG makes 362hp with sohc and ONLY 3 valves per cyl.what's their secret?

 

uhhhh u just reiterated what i just said man, in no way shape or form was my comment incorrect.... im saying by how the guy who started the tread, that it can be confusing to people

 

u can do good with 1 cam, u figure it to be less rotational mass, less parts, the $ saving issue could be a part of it

 

2 heads 1 cam in each, so single over each head = sohc

 

I don't know all the details on the C55 AMG engine but there are a lot of factors that determine the power output of an engine, including, but limited to:

1) displacement (bore and stroke)
2) intake design (including NA or turbo/supercharging)
3) head design
4) cam profile
5) piston design (compression)
6) exhaust design
7) fuel management
8) engine speed
9) frictional losses
10) torque/power emphasis

There are a lot of other considerations/compromises to take into account in engine design that detemine what power output is expected, including, but not limited to:

1) cost
2) fuel economy
3) reliability
4) the vehicle it's going into (engineering)
5) competitive vehicles (marketing)
6) expected performance
7) manufacturing logistics

I would say a blown and huge V8.

 

Actually there is no real difference having SOHC and DOHC with the same 24 valves - no manufacturers use a split pattern cam (different specs for each valve in the intake or exhaust sides); so stop thinking DOHC is better, its not. If it was a 12 valve SOHC vs a 24 valve DOHC, that is a different story.

The Benz makes that power becuase it has 2 more cylinders and 2.3L more displacement. actually for its size, its not very efficient in terms of power output at all.

 

Ahem... I believe, and I am no youngin' although I am no engineer either, that a DOHC engine, although it "revs" quicker and might produce "slightly" more power, it does so at the cost of lower torque and a more "compressed" power-band. I mean, if I am wrong on this, PLEASE correct me, 'cause it has been more than 20 years for me "knowing" this. Is one better than the other? Is europe better than USA? is Disney better than Universal???

Heck, I think it is differnet strokes to different folk, and I am sure one is better than the other in some respect or another, however, not all the time under all circumstances. For everyday driving, I think I really like the power the TL-S puts on the pavement real low on my Tach spread.

Then again, as always, I might be coming in from left fieald.... =D
