Honda Car Forum

this is on the honda ridgelinepeople are telling me it acts as a "turbo"but the dealer is telling me that at times when the truck does not need all 6 cylinders the engine switches to 4 cylinders, is this true??he was saying that it was the same thing that the GM suv's havethis isnt the same sales guy that i got the car from i got the car from a diff dealer

OK. your dealer (salesman) is an idiot.All it does is at a certain RPM, a solenoid controlled by oil pressure locks the rocker arms together with another rocker arm riding on a bigger lobe (with more duration) on the cam. It changes your valve timing.Some of the newer ones actually advance or retard (rotate) the cam in relation to the piston movement.Hondas don't have cylinder shut off (they don't need it)

no, its a 6 which is always a 6. u cant take out 2 and run it like thatno, she wants to run it on 1culiner, so tell her how

Actually, V-Tec stands for Variable valve timing and electronic lift duration control. Basically in a nut shell, Your cam shaft opens and closes the valves that let gas into the engine and exhaust fumes out of the combustion chamber. The V-tec has something called a dual stage cam shaft. Basically giving your engine more power at low RPMs and more power at High RPMS.Other engines have a single phase cam that only has one demension. The V-Tec lets the valves stay open longer at higher RPMs letting the engine breath better and rev higher, while letting you have the power you need for street driving. In a 6 cylinder, it usually kicks over at 3500 to 3800 rpms. In a 4 its a little higher. Its racing technology brought to the local dealer.

VTECH is a cordless phone company. C'mon it's right ontop of your valve cover.

Unlike everyone who has posted here so far, the guy at the dealership was almost CORRECT! Everyone, so far, has described Honda's old version of VTEC (no H). The newer engines come with iVTEC, which is a little different. But the V6 Honda engines have an even different version of iVTEC. At low rpms, the valves on 3 of the cylinders close shut. This helps greatly with fuel economy, and "coasting". At a certain rpm, the cam profile changes to allow the valves in the 3 cylinders to open with the rest of them. 4th paragraph down: http://www.123usedcars.com/road-test...y/index.htmlIf you do a google search of "ivtec v6" you'll find hundreds of links about it.And VTEC or iVTEC does not act like a turbo. People exaggerate how VTEC feels when it kicks in. Some of the B-series engines will let you feel it a little more than others, but it's nothing like a turbo. In fact, most of the time it's just in their head, from hearing the exhaust get louder at VTEC cross over.

For your question about the vtec the answers here are close enough. Check the link below for details.As for the switching to 4 cylinders, the sales guy is an idiot. He should really learn his product. The Ridgeline comes only in a V6 with out the VCM.The VCM(variable cylinder management) is only available in the 2wd Pilot, Odyssey EX-L/Touring and the 08 Accord(except the 6 speed coupe)

I'm not expert but I do have a vtec. At low rpms I believe it runs in 4 cylinders and after a certain rpm (say 5000) the other 2 cylinders kick in to produce more power. its a mystery to me but I know that you can definately hear it and feel it when it kicks in.

maybe you'll find the answer here:http://www.carsaddiction.info/

well i dont know about the new vtech's but i had a 1995 civic vtech and if they are still using the same concept then it goes like this....the vtech is different from regular honda motors in that it has a more powerful cam that allows the engine to be driven at a higher rpm before shifting gears (manual or automatic). In my opinion the dealer is being false. Most people who have vtech's really dont know what to do with them because it is really not activated unless you floor the gas pedal. To be put more simply, vtech allows you to accelerate faster than non vtech cars (i.e. if you were racing against a vtech motor and you had a non vtech engine you would probably reach 60 mph in fourth or fifth gear whereas the vtech would reach this speed in 3rd gear in some cases maybe 2nd (souped up))...........The moral of the story is vtech adds acceleration not top speed. Parts are more expensive and if it's not a manual transmission you won't get the full effect and probably burn up the tranny.P.S. Not a mechanic but a honda enthusiast. I'm pretty sure that this is 100% factual info. HOPE I HELPED!!!!
