If turning very hard would VTEC disengage because of the shift in oil? Just a thought because my friend took a hard corner in his DOHC VTEC civic today and he said that the car hesitated while already in VTEC a little bit.

Tried to search, but I'm dumb.

 

Oil could be low or he might need a baffled oil pan.

 

your probably outta oil, check yo chit!

 

I say he's low on oil, like everyone else.

 

good advice. i love my moogen pan. Nice welds and craftsmanship. You pay for what you get.

 

it's one of those things i wonder why acura/honda never revised

 

I used to take some pretty crazy turns going pretty crazy speeds and never had this problem.

 

I have this same problem. The first time my oil was low. I thought that was the reason, but it is not. There is a turn at the end of the 710 going to long beach,ca. There are a series of turns back to back. The last turn is a sweeping left that will last for 10 seconds at 80.

This is the only place it happens to me, but I can reproduce it at anytime. While doing the sweeping left in 3rd at 6.5-7k rpms, the cars stutters. Feels like hitting the rev limiter, but it is just vtec disengaging. Then I get a check engine light. Both times the code was vtec failure. I figured it was oil starvation. I avoid that now.

 

Low oil. Could also be low gas. I find it hard to believe you can oil starve a B18 full oil on the street with street tires. I have been racing my GSR for 3 years with the stock pan and have YET TO DROP OFF THE CAM AT ANY TRACK. This is with R tyres, good suspension, etc. I also keep the oil at 1/2 qt over or full at least.

Moral of the story, check yout oil and keep it filled.

 

vtec is harder to hear in gsr (asumeing stock cams). maybe you are falling out and just not hearing it.

 

Since it sounds like its a hybrid, how bout a loose wire?

 

as I was thinking...
Cause ya know these Hybrids can be a pia

I'm pretty sure you are having oil surge...

Check your oil pressure...

 

i had this happen before, and oil wasnt low... baffled oil pan might help if you get that often..

 

I had this problem before also, my car was not low in oil. What had happen is the seal on the oil pick up was not perfect.

Has the bottom end been cracked open.
Also does your oil light come on when making the turn.

I would check with an oil gauge first, if it reads low I would investigate.

I ended up spinning a bearing because of this.

Good one! You can hear it just fine with an AEM and open exhaust. Even so, I think the mad loss of power and the CEL would clue me in.

Either way, there are more Honda racers running stock pans then not. Oil starvation in turns is just not a problem on Hondas.

 

Spiff it is better to be safe than sorry. $250 for a baffled pan is a lot less than $5000 on a brand new motor. That is life. End of story.

 

On a GS-R with stock exhaust, header, etc this is true. On a race car, this is far from true.

 

CEL light would not come on falling out of vtec.

 

it would if the ECU recorded a VTEC Pressure failure. Granted, that wont generally happen in this case...

 

yeah I agree that with mods you should have no trouble hearing vtec on a gsr. I was just stateing that it is a bit harder (not imposible). Also how would I know what mods he has done to his car? I know several people that track race stock cars.

 

I have fallen out of vtec before do to lack of oil pressure. I did not recieve CEL. However I did get an oil light flash at the instant it fell out of vtec.

 

I think the worst just happened. Heard from a friend that his motor is gone.

I'll talk to him today to see what's up...

 

Oil light is far worse than just falling out of VTEC, hope you filled that puppy up fast.

 

It will. Believe me. Code 21 I think, general vtec malfunction is what I got when it happened both times.

At high rpms you WILL hear and feel it when you fall out of vtec in a gsr. My exhaust, headers and intake attribute to this also probably.

My motor has never been opened.
