No flammers or trolls please. A simple question, and should be a simple awnser.
Thanks in advance

 

HIGH compression and TODA vtec killer cams or somthing of the like

 

Exactly this. Sounds like Vtec killer cams.

 

Well the cams, according to the vid poster, are skunk2. But ive never heard them sound mean like that before

 

 

Here's a simple question; Why?

 

MAYBE those are pro 3's but it really sounds like VTEC killers.

 

Nah its not vtec killer. He has a dyno vid and you can hear the vtec crossover. No awnser from the vid poster, just says skunk2 cams in the description

 

if the primary and secondary lobes are really aggressive the idle will be really lopy, like a drag car or built muscle car. when you get small displacement it sounds like an oversized popcorn popper. The point of VTEC is to have an aggressive high rpm cam profile while maintaining low RPM idle stability and driveability.

In racing, where VTEC means very little if you are on the high cam all the time (or never below 3k rpms) then it makes sense to run a cam with aggressive low RPM lobes or as some stated VTEC killers. The benefit is a more stable oil pressure and sometimes less moving parts.

People who run this on a daily driven street car are scene kids.

 

I understand what vtec killers are, but there just skunk2. Cams, so thats really what trying to figure out, how fo get the skunk2 to idle like that.

 

Why care, be more concerned with getting your car to run properly instead of trying to emulate what another car sounds like.

 

Again, why? This is almost as bad as the people that try to get VTEC to "crack louder".

 

Because racecar grumblemarc. Because racecar.

 

Well it sounds cool, but its a NA build and i bet it doesnt go that fast. He just has monster Lobes. Like someone stated the point of VTEC is to have 2 sets of lobes so you can maintain drivablility while in low and have power in high. Those are some very beefy cams though, I dont really see the point of having low cams that are that agressive unless you are doing a non-vtec build.

 

the user isn't doing anything to make his car idle like that, he has cams the have aggressive primary and secondary (outer lobes) and that's what happens when you have a cam that has profiles that have too much lift and duration for low RPM and idle use.

sounds just like this

 

Why the hell are you worried about what your car sounds like? If you're worried about anything cam related it should be performance.

 

Yeah, it gets the performance, but if I want the sound to go with it, then I will. I thought i said I wanted intelligent awnsers only.
Now, I get that thats what makes the idle, but there skunk2. Thata what im tryi g to figure out, unless skunk2 has cams like described above?

 

You're getting intelligent answers. That's what you don't like, lol. Also, I read this on some other honda tech thread, but you can get a similar sound if you pull one spark plug wire. I've heard it can effect your powerband by up to 25%.

 

I was referring to the post above my last one. I appreciate the other awnsers.

 

That video has so little info it's not even funny. Let's just assume Pro3 cams so big primarys, probably high compression and obviously open header, with a full exhaust it wouldn't sound that nasty. But who knows if the cams are even degree'd correct and if it's crummy tune or not

 

Bro, if the Skunk2 cam has aggressive enough primary and secondary lobes then it can sound like that. Sub 4000 RPM operation will blow, it will have shitty idle quality, shitty driveability, shitty fuel economy, cams like that are intended for track cars. The beauty of VTEC is so you can have the best of both worlds, high RPM power and civil low RPM operation.

How much more intelligent replies do you need? It's quite obvious the main reason you are wanting them is because of the sound first and performance second. These kind of cams are designed to boost mid to high RPM power at the sacrifice low RPM operation, like road racing. Are you going to drive your car at 4000 rpms and above all the time, winding out to 8000+ RPM's?

 

Only if he has a B16, because that's damn near the only usable powerband of that engine anyhow lol.

 

for performance driving, yes. for civil daily operation, no.

 

My B16 was open header since I smashed the exhaust in a really bad dip in the road. So most of the time I had it, there WAS no "civil" daily operation, lol.

 

Can somebody tell me what VTEC killer cams are?
