I was looking at some info about the R18 engine that's in my car. I was curious about the VTEC controller cause I've never felt the 'kick' that's usually associated with VTEC. After a little more research is found that VTEC on the R18 eninge is somewhat similar to the VTEC-e from way back when.
It's said that during idling, the VTEC will alter the valve timing to leave the intake valves open longer to reduce pumping loses. It also has a variable length intake manifold (No clue how that works),that is said to help with torque.
I'm starting to think that I would be making better mileage with the manual even if the 5th gear is taller. Between the reduced pumping losses, the injector shut-off when decceling in gear, and just the general aerodynamics of the car I don't see why it couldn't get 45mpg and above with out any mods. I think Psyshack has touched numbers around there, but I'm not sure. Maybe I should look into trading mine car in for a stick.....
It's a really interesting engine to say the least. I remember reading an article about it a while back which said it delivers the power of a 2.0l engine with the fuel efficiency of a 1.6l. Pretty neat stuff.
That video was pretty cool. It kind of makes me not want to mess with anything on the car now though. I wish there was more info on the technologies in the vehicles made now-a-days. Although I guess you average person doesn't really care about that stuff. Plus I sure the companies have all kinds of reservations with putting their designs out in the open like that.
