Euro performs better

[Euro76]

Last midnight when I try to accelerate, from 5800rpm onwards, the car gets sudden increase in speed and rpm, it kicks really hard in winter nights than it was during summer nights. I've never thought of how impressive K24 engine is, since I drove Euro in winter for the first time. It sucks cold air (it was 5 degrees last night). I really thought the vtec kicks best in winter, I don't get this in summer, vtec does not kick really hard even at night time. I downshift and upshift the gears, the engine is just so responsive...and the 6MT is really a gem! And...love the engine noise last night...it really screams

The reason VTEC doesnt kick in as hard is because of the Variable Cam Timing (The i part of i-VTEC), the engine is already going hard before traditional VTEC kicks in, so its a lot smoother than say a B16A.

When full Variable VTEC engines are released, there will be no VTEC kick in at all

Yep the Euro rips hard in winter, especially with a clean/new air filter and new oil

Dont bother changing the Tranny oil that early, it lasts much longer than engine oil since MTF doesnt deal with dirty combustion.

Except that transmission oil doesn't get filtered. But ideally, just change it every 1.5 to 2 years.

Is there a 'magentised' bolt or part to keep some of the metals from running within the oil?

Having said that, that gearbox oil could still have a silvery/reflective coat on it. Not good for gearbox.

As for VTEC kicking in - well its just a power drop before 5800-6000rpm when it is continuing on its previous would-have-been continuous but slightly dropping away power curve anyway. I think its very psychological.

Honda could have programmed it to be nearly completely linear from low rpm to redline in the beginning.

The stock bolt is not magnetised.

I wouldn't rely too much on a magnetised bolt to effectively prevent metal shards from recirculating in your tranny, dunno why Honda don't use tranny oil filters though..

[Omotesando]

Well wouldnt rely on it but the difference between having one and having none might do more good than harm in the long run I suppose.

The pertinent question to ask is - why isnt one there? Is there a reasoning behind its absence? You never know. May be Honda thinks its better having none there!?

Anyway, I have an issue to raise more relevant to the topic.

People often say the Euro loves cold air. I really want to say that nearly all cars perform with cold air anyway, especially turbo cars. The difference on a cold and hot day on the Euro is nothing compared to the difference on a turbo I can tell you that! Its much much more laggy when its hot in a turbo equipped car!

In a turbo-equipped car, the intake charge is pressurised and ends up at a higher temperature. Couple that with the higher air density in your cylinder which is then compressed means that your ECU will be dumping in much more fuel just to prevent pre-ignition.
