Default VTEC not working...I dont think

D16Z6, TurboEdit, NG60, 14b, 450cc's

So I got this here Z6 in my 89 hatch boosting ~8psi. Got a test light hooked up and it comes on at 4500 just like it should.

Should I be able to tell when vtec kicks in y0? I have tried it with vtec turned on and vtec turned off and it makes no bit of difference in sound or performance whatsoever. I don't have an oil pressure gauge hooked up at the moment, but im 99.9% sure its fine. Car ran a [email protected] at the track and I'm convinced the vtec is not working. I removed the solenoid and the screen was as clean as can be. What else can I check/try?

yup wire is hooked up to the solenoid wire. lights up just like it should, turns off when it should but i gots no vtaks. ive tried 'easing' to 4500 so I could hear/feel more effectively and there's nothing. Guess imma take the valve cover off tonite, see if theres some gunk somwhere (doubt it as I run synthetic), and try a spare solenoid I got.

Vtec is very audible, 100% you should hear it if its activating

Maybe you have vtec disabled in TE?

It's still audible enough to hear.

I rode in a friends car once, to try and see if his Z6 was switching over, and we had to drive right next to a big wall to be able to hear it. So yeah, you can hear it.

take the damn solenoid apart and clean it, make sure the plunger actually moves, etc.... or hook 12v straight to it and listen for the click. on a D its not noticeable at all. and easing to the crossover wont make it engage at the same rpm as WOT will. if you are getting power to it and its not clogged or froze up, its working. if you move the crossover back up in the rpm band closer to stock it will be more noticeable when the low cam is starting to run out of juice.

the only single cams you will hear vtec on are vtec-e motors. With a turbo it makes it even more unnoticable
