What do yall think about the Vtec killer cams, what are they good for, Boost, all motor??? Someone shed some light on this

 

i here there pretty good they say it makes the vtec melt the front tires when it kicks in

 

Vtec killer cams are made to basically be in VTEC all the time, unless you have a fully built motor dont get them, they dont even make any power until like 5000 rpm..

 

if they make vtec stay on, how come they don't make any power till 5000 rpm, or do you mean they make power throughout the whole range but 5000 and above is their peak power?

 

They don't make VTEC stay on. There is no VTEC with those cams, hence the "killer" in the name.

 

so then what are their advantages, will they make the motor run harder than if it had vtec cams

 

They will most likely not perform any better than stock cams if not accompanied by the appropriate valvetrain upgrades & higher compression.

You are correct, i read a great post about these cams a while back.

OP: search for vtec killer cams and you should find some good threads on them. they are designed for all motor.

Never mind i have nothing to do so here are some

I was under the impression that those camshafts just have all of the same size lobes so that when vtec actually does engage, it is no difference and that is how the vtec is killed.

 

Your impression is wrong, because vtec no longer "engages" with those cams....

If all of you people would actually read a little bit and stop assuming, you'd see that there is no vtec lobe.

 

"Vtec killer" cams completely eliminate the vtec function. They only have one lobe, no primary to secondary changeover ever takes place.

There best for high compression engines that spend all there time above where the powerband starts. Someone stated that its 5K RPM, sounds about right but I am not positive. A good example is running the quarter mile. When launching, you keep your RPM's spinning faster than 5k - when wheel spin turns to traction.

 

these cams sound so mean... look em up on you tube! i can see why you can't run it daily!

If you want to get technical, they have two lobes per cylinder (the primary and secondary), and no VTEC lobe.

Right.

 

lol at this thread. Thanks for posting something to make it technical.

 

well, nobody mentioned two huge benefits. They have ROLLER ROCKERS and the rocker design allows for higher lift.

wow, how about you go expletive yourself.

sorry guys i mistakenly commented figuring they where similar to ferrea and cranes "vtec killer/illiminator" kit. my bad for not being perfect. leave it up to FLA to set me straight i guess.

Understood, I was saying that there is no changeover.

 

they are crazy expensive...especially the toda kits whats the actual power gain anyway for 2000 dollars??

Copied from the Toda site:
http://www.toda-racing.co.jp/e....html

Design
The primary and secondary lobes are designed to be the same size.
Overall construction of the cam has been heavily revised. With areas of stress,rigidity and weight all greatly benefiting. Normal cams are created from solid blanks, but the VTEC KILLER CAM is produced from a hollow blank, which not only reduces weight but also improves valve timing accuracy through a reduction in flexing.
The cam is designed to bed in quickly and have a low wear rate.

Characteristics
The mid rocker cam is removed & both pins are changed,reducing the valve train mass,for better responce.
Disabaling the VTEC system removes fluctuations in oil pressure system,securing a reliable oil feed to all the main moving campornents.
Lost motion valve should be removed.
Should be used in conjunction with 4valve throttle body for best effect.


Hope that helps
