Vtec in Cruise mode?

DTNguyen107 · 04-26-2008, 06:32 PM

I was in 3rd gear around 3000 rpm. Had an itch on the bottom of my right foot. I turn on cruise control real quick while I give a quick scratch.

Traffic was catching up to me and I was still struggling to scratch that itch. So I hit the accelerate button up to 4000rpm then to 5000rpm. I was thinking... hmm this can't be healthy for the engine.

Still struggling to scratch that itch and traffic was on my butt. Eventually I just held the accelerate button all the way to vtec. Felt a slight push when I cross over 5800rpm. People pass by anyway looking at me all weird. I guess because my exhaust was roaring but I was hardly going anywhere.

Well anyhow that is my random story. I'm wondering if I'm the first to vtec in cruise mode?

that must have been some itch huh?

***citizh*** · 04-26-2008, 06:53 PM

lol, at the loudness and not going anywhere

***illusionstwice*** · 04-26-2008, 06:55 PM

its not good for the engine if u just let it stay in vtec range. Like if u just set it to stay at 6500 rpms...not good. Plus it will kill gass. Just shift man! lol As soon as u hit the clutch while on cruise, it turns off anyway.

I'm not so sure about this. Sure, it's going to spend a lot more gas at that cam profile (that's really the point -- more O2 and more fuel into the cylinder), but as for hurting the engine to run at 6500 rpm, I disagree.

The first video I saw on the Civic Si was over at Temple of Vtec. He ran that Si all day at the Dragon, keeping it in the vtec range.

.

Our engines are designed to be abused.

Although, cruising in Vtec is probably a bad idea on principal alone.

DTNguyen107 · 04-26-2008, 10:08 PM

Anybody remember that S2k?

Drove at 7500rpm for 4 years straight.

I think my 15 seconds of vtec cruise will be alright

shawnono · 04-26-2008, 10:19 PM

HAHAHA! Mann! what an itch!

I wouldnt say designed to be abused but built strong, to handle track and everyday conditions.

Do you have a K20 or R18? I ask because the K20 has a set vtec switch point and the R18 doesn't. If it's a K20 than you can hit vtec in cruise but if it's an R18 you probably can't because the R18's vtec switch is based on engine load not rpm, so you could redline it under low load (like in cruise) and not have it switch into vtec. (I saw this in the motor bolt on forum)

DTNguyen107 · 04-27-2008, 08:25 PM

How to respond to you...

pkkid · 04-27-2008, 08:28 PM

^ LOL R18 is always in V-TEC

IceWindius · 04-27-2008, 09:21 PM

The R18A and the K20 have two differently different V-tec modes. R18A's is engaged for the lower RPM "economy" driving mode while the K20 is the more typical "power, high RPM" mode.

e60.deluxe · 04-27-2008, 09:25 PM

err, um you could probably drive at 7500RPM all day and not do any major damage, its just that your engine would need rebuilding every year.

also you cant vtec in cruise control. i dont know how you did it, but ive tried before. increasing the speed with the steering wheel button, you will not be able to set the cruise to past 5000 rpm or so. the speed will just come down.

Jay4dnb · 04-27-2008, 09:45 PM

maybe i misunderstood, but why would you be in cruise at such high rpms?

How much you want to bet?

I made a right turn at red light and had an itchy moment while traffic was gaining on me.

Happens to me all the time. It was the reason I got pulled over the first time in 15 years.
