iv never heard of anyone doing this, but it seems like it would be a good idea. if i took the rod that links all three lobes on the camshaft at 4000 rpms for the vtec, and somehow got it to stay there all the time, then i would have constant vtec running. it would be bad for gas mileage at low rpms, but with my dohc vtec, i dont usually go slow. any opinions....?

 

why would you want vtec on all the time?

 

that is brilliant, you better acquire a patent on that before honda steals it.

You've just invented the single static cam profile, you're a genius!

Nope, Crazy Dave invented that, sorry. You guys are way behind the times, DOHC VTEC single static cam profiles are soooo last year. Our ricer friend Cory wouldn't fix the KS on his B16 swap, refused to pay a dollar, but whined incessantly that he "didn't have almighty JDM VTEC anymore" to the point Dave got sick of it and used a WOT switch off of a Volvo to activate VTEC at WOT on the B16. Cory got so happy he just removed the switch to an on/off push button on his dash, he'd make the idle cam and lope with the push of a button. Impressive!

FWIW, the car had five broken valvesprings within two months... probably partially due to the guy hammering on me for a chip so he could "rev to 9500" as if that had anthing to do with anything. I gave said item to him for free (broke bitch) because "I want to see your engine blow up." Mission accomplished

 

okies about the constant vtec! why not just get high profile cams like something from skunk2 or toda or crane and still have the high intake flow at low rpm's while have even more power at higher rpm's

 

They already make a "constant VTEC" motor.

It's called a B18A with Crower 404s.

 

that is why Toda made VTEC-Killers
to eliminate VTEC crossover

Yes, but the killers keep you in constant non-vtec. Obviously that isn't cool enough for some people.

 

not again...bah

 

But seriously though if you wanted something that had extreme high lift cams and ran constantly then buy a muscle cars, literally those single cam v6's have some of the largest profile cams ive ever seen,

 

the pin that links the high and low rpm lobes together is driven by oil pressure. how is it possible to hook up a switch to that. im not saying that it is impossible, im just wondering how it is?

 

why not just fabricate a plate that feeds pressurized oil directly to the rockers instead of being governed by electronics

 

im not really that educated on this but i dont think it would be called vtec anymore haha doesnt the V stand for variable or somethin like that

If you are going to do that you might as well just build a b18b or a b20. The whole point of vtec is to have low and high end power. If you kept vtec on all the time you would get no benifits. Youl would be slower off the line and probably burn up the vtec solenoid. That is of course if you supplied constant power to the solenoid.

 

a VTEC head flows wayy better than a LS head....I am guessing that is why he eould want to do this

 

Or you could ask BMW how they designed their VANOS system...(continuously variable timing, etc) and i'm sure they'd help you disign one for a honda engine.

It kind of defeats the puropse of VTEC....

I can't think of one reason this would be a good idea. Not one. It would give you less performance, worse idle, and worse gas mileage. What is your reasoning for doing this again?

 

i did this back in 99 when i had my d16z6 in my 94 Si i had installed a web cam on it and i rigged a second vtec solenoid and made it work with a msd window switch,but as you can tell there are no obvious gains

 

Why do ricers think having VTEC on all the time does any good? In most B series engines, VTEC does nothing until 5k RPM anyway, and if its activated any earlier, in my case, less power is made.
Leave it as Honda designed.

 

would setting vtec crossover at like 2000-2500 even help spool times??, or is it just plain stupid in all situations?

No, it would probably worsen spool times. It's just plain stupid.

 

all that the vtec does is allow your valves to open sooner and stay open longer, therfor giving your engine more oxygen. i dont see how you would lose power at low rpm just because you give it more air. granted, i would have worse gas mileage and a high idle, but over all, i think that it would give me more power off the line and at high rpm, if im wrong, please explain how...

i could go with differnt camshafts, but money is tight right now, so im trying to be cheap...

 

does anyone have that site with the "how it works" on vtec i think some ppl here need to read that

 

Because more oxygen is better at high engine speeds. When the rpm's are low, you don't need as much oxygen to run it. By doing this, you'll probably run lean all the time unless you change your fuel maps. Save 300-400 bucks and get some Type R cams.
