stock about 5,800rpm
So high?... is there a reason why the car feels a bit lax from standstill; but once moving a little bit the acceleration is considerably better?
your spot on.. vtec engage at 5800 rpm....Quote:

1.8L i-VTEC.
The 1.8L i-VTEC is special. It can activate the 2nd cam at any RPM by using hydraulic actuators. It depends on the engine load. At low engine load, you have your long duration intake cam that works with electronic throttle to do a full throttle, long duration intake stroke. When the intake stroke is complete, and the compression stroke is beginning, the intake valve is still open so that there is less resistance to the initial compression.Quote:

So technically, you have no VTEC point RPM! It can be at any RPM depending on the load on the engine.
You do have dual length intake manifold, which is using long runners from idle up to 5200RPM where it switches to the short runners at 5200RPM.
Watch this video. It's great info on your engine. Wish my engine had all those technologies such as the molybdenum coating.

how old is this freakin thread??
by the way does it sound stupid that vtec engages at 5,800 in EVERY b series engine with vtec??
old skool vtec as opposed ott his new i-ctec (WOOO) does still rely to an extent on load...it doesn't just automatically switch itself on at 5,800rpm...
if i hardly touch the acelerator i can rev past 5800 and vtec dont engage. my motor is stock and vtec engages normaly at 5200-5300. and not only that if i gun it out of a corner i can be doing 4300 and due to the load vtec will engage.
Is there anything special about the 2.0L in the sport?Quote:
