Vtec from hell.
Can't see the vid, but I had fun in my buddy's Integra a few years back. He'd just gotten the engine built n/a (255 bhp), and was bringing up the revs slowly in his garage, with an open SMS 4-1. When VTEC engaged, it scared us, it was that loud. It had some kind of crazy Crower cams...

2) VTEC shouldnt be set to engage when the car isnt moving.
We're talking about a B18C block, stroker crank, 12.5:1 Cr., P&P, etc. I understand your skepticism, but it's misplaced. If it makes you feel any better, the owner had more money than sense and blew the engine with a combination of stock fuel pump and stock radiator (IMHO), and general hooning.
2) Many things are possible in the realm of EFI tuning, including engaging VTEC at a standstill. I don't know if it was intentional or not, but his car would do it.
the better a vtec engine is tuned, the less obvious the vtec engagement point will be. at least while driving, i've never heard one engage while sitting still in a garage though.
When the engagement point is set correctly you dont really feel it, but with all B series VTEC engines you alwasy hear it. Even when its set right, simply because youre going from a small exhaust cam to a suddenly much larger exhaust cam.
With the D series engines you dont hear it very much because it only has VTEC on the intake side, not the exhaust
How about a 300whp NA B-series? Local shop, good guys.

You CAN set it to do that but youre not supposed to, you have to go out of your way to set it like that in hondata/crome/uberdata/neptune/ectune/etc

yes, why i said it's not as obvious, certainly not startling. it's not just the point, it's the tune up to and after the crosssover point. most people just tune the wot on the vtec engaged side. i've tuned like 30 b-d series hondas
yeah, kinda. a d-series is only a single cam so there isn't the same jump in flow like in a b-series.
