Noticed something about the euro

[Faiz]

Upon intense acceleration, the euro revs up to 7000 revs per minute and than changes the gear (automatic euro) Is this because the vtec full potential is unleashed at 6500 rpm? Something like that, not too sure where i read this. Oh! i remember the euros torque is accesible at 6500 rpms?? something like that. And this is the case when i just puch the accelerater down and the engine revs like hell. By the way i love it how the engine just acreams at you upon acceleration. :thumbsup:

Heh?? Redline is at 7000, so it has to change gears. You step on the accelerator hard, computer in car knows that you want more power and it will automatically keep it in gear or downgear for you. All automatic transmissions will do this to an extent, but the Euro just responds quicker than other.

As for power, the Euro will reach 140kW (max power) from the engine @ 6800rpm. Max torque occurs @ 4500 rpm, just before VTEC, not 6500 rpm. If you knew how VTEC worked, the primary cam (used when it's not in VTEC) will produce the most torque, while the secondary cam (used in VTEC) will produce the most power.

Euro screams?? Haha...is it me or do I find i-VTEC too quiet. Bring on normal VTEC!!

doesnt iVtec work pretty much on demand and not after a certain RPM like the old VTEC??

I dunno...but I feel there is better throttle response after 5K all the time, so I believe it does work the same way. I heard the old VTEC's only had Variable valve Timing and Lift Electronic control (thus VTEC), while i-VTEC has VTEC as well as Variable Timing Control (VTC) or cam phasing. VTEC will improve top end power, while VTC will provide more torque across whole rev range. Read more here:

So yeah, VTC will work on demand, while VTEC work as a mechanism in stages.

hmm new post wrong area, seems that i cant delete it tho :thumbdwn:
