I was just curious, why does the S2000 use single overhead cam instead of dual overhead cam? Isn't dual overhead cams better?

 

the s2000 has a 16-Valve DOHC VTEC engine

 

Did you get a defective S2000? I can't imagine any owner not knowing that they have DOHC

 

If it's SOHC, then Toda just sent me an extra camshaft for my S2000. Maybe that's part of the upgrade... SOHC -> DOHC conversion! Hehe... just playing.

Yes, the S2000 is DOHC.

 

Can someone explain the advantages of SOHC vs. DOHC?

Thank you.

 

dohc can create more power, dual cams allow for a steeper angle on the valve guides so you can put bigger valves in a head that has dual cams
sohc is just easier to repair and maintenance is cheap because there is only one cam, one timing adjustment, and one valve train

 

Did you mean to ask "Why VTEC instead of I-VTEC for the S2000?"

 

In OHC motors the camshafts (which define when and how much the intake and exhaust valves open and close) are on the top of the engine (head), and either actuate the valves through direct contact (ie, all Honda engines) or through a short linkage (ie, many Toyota engines). SOHC means that the same camshaft controls both intake and exhaust valve lift. It's very tricky to engineer an engine so intake and exhaust lift can be equal
and still more or less optimize output, but it's possible- and the advantage is less weight and less complexity. Of course, el-cheapo SOHC cars just do it for the cost, with no particular care for optimizing output..

 

Is this question seriously being poised by an owner?

 

ok i dont think its that big of a deal for him to ask somehting like this, no need to rag on him like so....it was an honest mistake....
