In the "noob forum" thread you can find useful information about cars, read up on there to get some knowledge about how things work

Also if you want to learn things for yourself check out the DIY section, theres heaps of useful info on things you can do to maintain your car.

For now try and figure out whats wrong, like zilli said your better off taking it to a mechanic.

I hear VTEC at 5700 as expected.

A B18C on the low-cam does not get faster after 5000rpm.

I can hear the cross over in that video.

sounds like a perfectly normal functioning engine.

Like string said @ 5700. The difference in tone is very pronounced.

Yep I can hear it too

i just noticed you dont seem to be accelerating quite quickly, so you must be in a higher gear?

with my dc2r vtec isnt as loud on third gear in contrast to first or second. lets say youre creeping up from 40 to 80, if i do it in second gear i can hear more crossover compared to if i was to do it in third

my single cam AUTO vtec cross over is louder than that (no offence but im being realistic) mite wana start at a lower gear and film again.

good luck with this

As said earlier (I guess you didn't read the thread), this is due to your engine being a 1.6L and therefore producing less torque at the low-end, so when your auto VTEC kicks in bro there's a bigger 'jump' in torque. Because the B18C makes more torque the 'jump' is less noticeable and so the VTEC crossover is smoother.

This is why B16A's also have a loud crossover.

This VTEC is fine, sounds quiet good actually

single cam = very quiet
