if i unhooked the vtec selenoid would it hurt the motor? even going over 6k?

no... but why would you want to?

 

i drive about 60 miles a day to school and work and other crap. im always tempted to hit vtec. i want to see how much gas i would save, and also quit buring so much oil.

if it was unhooked, the car would still go up to 9k, vtec just wouldnt engage, correct?

 

I am sure that someone knows better than I, but I would NOT recommend spending time above the standard point of vtec engagement if you have unhooked your vtec switch.

Honda motors rev to the roof, and they can do it for years (my previous si had over 200K on the b16 before I pulled it, and it was still very reliable)... BUT... the engagement of vtec also includes the injection of additional oil, which we all know is the sex-lube of your motor.

Spending time in the 6k+rpm range is putting a lot of friction and load on a motor that you will in turn be stealing the recommended amount of oil from.

Like I said before, I could be very wrong, but this was what I was led to believe talking to many honda people.

I would just say try to be very disciplined on your right foot. For some reason, I am much more gentle on my s2k that I ever was my gsr swapped em1... I rarely hit vtec and usually average around 23-25mpg in the city.

that does make a lot of sense. i prob wouldnt go over 6k.

i just need to get more self control. this is why 18 year olds shouldnt have s2k's

its called self control, but not going into vtec isnt really going to save gas.

i daily'd the **** out of mine for almost 2 years goign 6k+ often thru the day and was still getting 280 avg to a tank and a max of 316.

 

it sorta saves gas. usually when vtec kicks in, more fuel is pumped in.

They got worse **** over there lol.

To tell you the truth man I drive as much as you if not more then you on a daily basis. And I came off of a integra b4 the S so I was liek wtf this thing is a pig when it comes to gas. So for about 3 weeks straight I drove real conservatively and barely hit vtec thinking my mpg would improove. And it didnt I maybe got 10-20 miles more to the tank and that was it. So I stopped driving it like a ***** 20 more miles to the tank wasnt worth it imo. I hate to brake it to you buddy but I dont think killing off the vtec is going to help.

Maybe try freshing it up a lil bit with a new fuel filter, some injector cleaner, new spark plugs and O2 sensors.

its really easy bro, i say it time and time again its all about proper shift points throttle position and load on the motor.
example
15% UPWARD HILL
3RD GEAR 5K RPM
4TH GEAR 4300 RPM STILL NO BOGGING BUT MORE LOAD ON THE MOTOR USING UP MORE FUEL.

USE YOUR GEARING AS TO THAT IS WHAT IT IS FOR. THE MOTOR HAS TO WORK LESS AT 5K RPM IN 3RD INSTEAD OF 4300K IN 4TH.
HOPE IT HELPS.

 

i think i got close to 400 if not more than 400 on my roadtrip home. went the whole highway 5 (285 miles) without filling up, and then some.. when i got home my gas light was on.. so i don't know.

but i agree with the other posts, because from my limited knowledge alone of how a VTEC motor works... it tells me that there is two cam profiles for a reason. (one's suited for low-demand, and other for aggressive/high-demand)

and lets say you hit the throttle and "forget" that you don't have VTEC, it won't switch to high-lift cams. which means there will be less air than should be for the motor.. i don't really know what happens after that (im noob) but ill take a guess and say that it'll go past the limits of the low-profile cams and cause unneccessary wear?

im not claiming to be anything, just my educated guess.

all in all, i would keep VTEC and drive more conservatively. or get a civic beater.

 

If you want to save gas, drive like a grandma you. Why would you unhook the vtec solenoid? Are you that incapable of controlling yourself?

 

You will get a CEL code and VTEC obviously wont engage.

iirc, honda ran the F20c motor for 2 weeks straight at 9k before the rocker arms started to fatigue.

So your basicly saying just run at higher rpms?

yeah i am trying to figure this out to. everwhere i read tells me to shift at like 4500 and that what i try to do. i havnt been hitting vtec at all either and i am still getting maybe 230 out of the tank my bimmer doesnt do any better on gas or else i would drive that, so i am about to get a beater car.

i have even tried throwing the car in nuetral when im going down hills.
