help a little honda boy understand what exactly is VTEC please
and what exactly does it do in my 2005 accord v6

 

VTEC is variable valve timing. It is a third lobe on the camshaft that the engine switches over to. For accords its more of a gas mileage thing. For civics and preludes and NSXs and Integras and things of this sort its a more aggressive cam lobe that adds power in the higher rpms.

 

Look at Wikipedia ...... under VTEC.

 

Youtube has a pretty good video on how it looks inside your motor.

 

It's like a turbo without a turbo!

 

Yeah, and according to the mechanic at Honda, it "kicks in" too!

 

Thats funny.

 

Lol it's a good way to describe it! And Mihalis, it does kick in at a certain rpm.

 

Its pure automotive genius if you ask me!
