for those who thought Vtec Kiler cams were not real...

http://www.youtube.com/watch?v=dHVCyj4GqPo i semi know the person that owns this car…

i was gonna put that one up but it sounds really bad.

tru! Its kinda crazy how you can get a 4 cylinder to sound as burly as a v8:)

it’s normal. that’s what a fat cam does to an engine. a v8 at full wind-up sounds like it’s in vtec. Reason being is the cam profile. the frequency in the sound is different due to the amount of cylinders, but you get the point.

I’ve seen and heard cars with these cams years ago. Who didn’t believe they were real?

VTEC, in theory, is not needed in full race cars that operate exclusively at 5000+ rpm. There was the Atomic SOHC drag car that disengaged VTEC as well that I believe was pre VTEC killer setups.

i just remembered that you had a conversation about with someone about that a while ago. a few people were skeptical about the whole notion. it was just by chance that i ran by this video. that one and the one about what happens when the crossover into the agressive cam profile kicks in. after seein all that, my question is: do you even need a special set of cams to keep vtec engaged at all times? I would just assume that you could keep the rocker on the vtec lobe locked to the others all the time. right?

I believe the VTEC killer camshafts just don’t have a “low” lobe at all. The car is always spinning on high cam regardless of RPM. I honestly don’t know how the solenoid operation is changed, disabled, or modified, or if it is at all.

They’re also hollowed out to reduce mass. Pretty cool. :slight_smile:

oh, wow.

Thats how I want my street car to idle :slight_smile:

Truly badass. That is as badass as our little fourbangers will ever get IMHO.

Nice job, overall on the first vid. Good posts! :rockon:

so after doing soem research im a little confused. Do these cams get rid of vtec, or do you always have vtec going. I thought they made it so vtec was always going untill in stumbled across this on www.inlinefour.com

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 response. Disabling the VTEC system removes fluctuations in the oil pressure system, securing a reliable oil feed to all the main moving components. Lost motion valve should be removed. For max performance, should be used in conjunction with TODA Sports Injection kit.

Both. There is only one lobe set, not a separate set for VTEC. So, think of it as a set of VTEC cams with crazy “high” lobes that just doesn’t have the “low” lobes. You are essentially in the same operating regime as you are in VTEC, so in that sense you are always “in” VTEC. The rest of the VTEC system is removed because you don’t need it to be engaged since it’s always “on,” so in that sense you’re “removing” VTEC.

what kind of valves/springs/retainers is that car running?

WOW! That car truly does sound like dog shit…probably works wonders on gas mileage.

how is a car with “vtec killer” cams not streetable??

i would say that it is streetable. just not street friendly

Because its hard as hell to keep an idle when driving normally. Its murder on the clutch keeping an idle at stop signs and lights.

it sounds like a weed eater with a bad spark plug:bored:

sounds like my old articat
