VTEC Engine

I have a 98' accord V6 Vtec SOHC engine.

My friend is trying to argue with me and says I don't have a complete vtec engine because I only have a SOHC and not a DOHC. He believes that for it to me a true Vtec it has to be a DOHC because the cams switch when the vtec kicks in. Now I know what VTEC means and I explained it to him.

Tell me if I am right or correct me if I'm wrong. In a SOHC since there is only one cam it is a high end cam. That is why the vtec boost only kicks in when the engine is at a high RPM. With a DOHC the vtec will switch from the low end cam to the high end cam.

The main thing is though. Is help me prove to my idiotic friend that it is a vtec

With a SOHC and DOHC the only difference is that 1 cam is for intake and 1 is for exhaust, where the SOHC only has the 1 cam doing both. But technically you're incorrect. Your SOHC has 2 profiles on the 1 cam; low and high. When VTEC activates it switches to using the higher profile of the cam. So with a DOHC, when before vtec kicks in both cams are using the lower profile lobes of the cams, then they switch to the higher profile lobes of the cams. Hope I explained that correctly. But tell your friend he is an idiot and clearly knows nothing about Hondas.

Tell your friend to do more research :rolleyes:

Fuck that. I'm just going to shot him with my Airsoft gun

LoL :grinno:
