Leaving vtec on for track car
Ok.. ive raced my 92 b18b turbo hatch at summit point raceway a couple of times. I have sold it recently and picked up a 92 prelude and put the h22a1 in it. I plan on seting it up for the track and turboing it running about 9-10lbs of boost. My question about vtec. can i just turn it on manually at idle and leave it on when i track the car, just tune the vtec map all the way down to idle. Also im looking at a turbo that can be fully spooled at around 3k rpm and hold to 8k. Im thinking a t3 super 60? The turbo i had on the hatch wasnt spooled till 5500rpm, and i didnt have deal with vtec but i had to deal with lag. witch messed me up.. cause im not exactly a pro yet 
. I would like something with solid power and virtually no lag. I would like to keep vtec so when im just crusing around i still get somewhat descent gas milage, and i didnt feel like putting different cams in and taking off the vtec since i just swapped the h22 into it. What are your opinions about the vtec engagement and turbo? Thanks

I'm not going to try to answer this one!!!
Except that your will loose basically all power down below. Ever dropped VTEC on a b16 or so down to about 4000rpm. Car feels slow as hell until the 5200 or rpm point. There is a reason why it come in that high!

Hook it to your horn so you can activate it by honking the horn. :1 Or hook it to the brake lights so everytime you hit the brakes, V-Tack engages!

Re: Leaving vtec on for track car
If you activate VTEC during low rpm low oil pressure, you'll just ---- up your LMAs and send a lot of metal particles throughout your engine.
If you dissassemble the rocker shafts, and fiddle the rocker arms so that the pins are always engaged in the LMA, then you'll be fine, and your VTEC solenoid will be useless.
I wouldn't worry about low end, personally. LS boys with cams don't complain, we are hairy chested manly men, all grizzled and ----. *flex*
However, none of this explains why locking VTEC is worth the effort... I still think you should do it. Be different! Don't let common sense stop you.

there is a reason v tec is turned on and off
how well does a race cam run down low and how does it idle?
go to honda web sight and look at the v tec ---- on ther it exsplains everything

Ok so what if i drive the car engage vtec then never disengage it.. Its oil pressure that moves the cam over correct? Well when it does this does it trap that oil pressure in there to keep the cam in posistion.. or does it rely on the constant oil pressure to hold it.. Say you were driving in vtec.. then lost your oil pressure... would your vtec slide back and dis-engage ? i know youd have more problems if oyu lost oil pressure.. this is just Hypothetically speaking..Also you wouldnt happen to know how much pressure it takes to engage it?
the alternative to all this would be learning to drive....
oh yea just so you know summit point isnt a drag strip.. www.summitpoint-raceway.com
the lag and the rollercoaster tq curve around the corners were messing me up.

Re: Leaving vtec on for track car
There would be no torque available with vtec down low. If you know a Honda, and why they created Vtec, It was to be able to get a High Rev, Top End engine to be drivable down in the lower rpm range, because not everybody want to run a motor up in the 5000+rpm points every time they take off.
No I didn't just drop Vtec down. I didn't hop on the Honda BandWagon yestarday. If you researched you'd find most people often raise thy're engagement point.
