What's the deal with VTEC killer cams?
Why on earth would you want to eliminate VTEC? Does anyone have dyno charts for these things that show they have any significant gain over some aggressive VTEC cams? What's the deal?
The name sounds like it eliminates VTEC, but I've been told that its more like you're in VTEC all the time... Like no crossover, but all the juice... Of course that could just be marketing
I'd like to see a dyno comparison on them too if anybody has one...

Because the lost motion assembly and additional rocker arms are dead weight (and something else that can fail) on a dedicated race car that will never spend time below the vtec engagement point.

VTEC is a street compromise. It's a combination of a street cam with good idle and good low to mid power, combined with a race cam that has good top end but would inherently suck at idle and low end.
If it's a race car, get a cam even more aggressive than the VTEC lobes, launch hard, get drunk and [freak] bitchez.

Well that would be obvious, but why run them in a street vehicle?

VTEC killers eliminate VTEC, so there would be no crossover. Only the high lift cam would be in use all of the time. I'm betting that VTEC killers would kill your low rpm power, I was just wondering if anyone had a dyno to show it.

bs you dont have vtec killers, there is no crossover, there is no vtec with these cams, your in vtec basiclyy the hole time
with these cams the vtec solenoid and the lost motion assemblys are disabled

true they dont have good low end power, but that doesnt matter at all, there designed for road racing, for race cars, there not all all desogned for the street, in a race car you are never in the low end where you loose power with these cams, your always up top where the power is

Cool, that's exactly what I thought. Don't know why people are so hell bent on putting them in their daily drivers though.
i dont have a clue why somone whould want these in a street car
listen to these things, they sound pretty badass, but hardly streetable

These cams eliminate VTEC so its not your in vtec all the time, its like you have a normail engine without vtec, with aggressive camshafts. People give you some funny looks when you drive around a honda that sounds like a V8. Why put these in a street car.... why lower a vehicle, why put motor mounts on a car, why a 6 puck clutch, why big injectors, why do modify a vehicle PERFORMANCE. not much to much in the much in the industry helps making a car more streetable, but the pros might at wiegh the cons to certain people
^^ He has it right. They were designed so people could basically run VTEC motors in their honda's and compete in leagues that ban any sort of variable timing/variable lift. Its true that they wont make more power than a proper VTEC cam because VTEC Killers are a compromise.
no_fear is def right..i am fixing my mistake on hearing vtec...it was because of my secondaries opening it sounded like vtec....yesterday was my first time driving without my stock intake mani and i dont hear it anymore.. i would not recommend these on any street car unless your running street/drag(more on the drag side) like me
I thought that there was a good application for FI cars. Utilize the wonderful casting of the B16/B18C and remove all the issues with the VTEC overlap.
I believe I read something about this on Endyn's site a lifetime or two ago....

A proper roller setup, is a whole hell of lot of valvetrain weight and friction removed. If the cams were the same profile the one without vtec would have better top end power, and be a faster revving engine. Vtec makes a radical cam streetable. Nothing about vtec Adds top end power, Vtec allows the choice of a radical camshaft that would never pass emissions, fuel economy, or drivabitilty standards that is required for a production vehicle. How does VTEC add horsepower?????
VTEC killers are highly overrated by the mass of fanboi's who hear youtube video's of the things barely idling and then think they are the ****. They are a strict race cam, designed for 5000+ RPM. They should not even be considered for a street car.
a good vtec cam will make more power than toda vtec killers ,toda killers if i remember correct have also 3 stages like normal toda cams, but they are not so aggresive since they are missing the small primarys,in theory maybe a more aggresive vteckillercam would make more power in above 5-6000rpm than the normal cam.
*edit cam specs from toda
Spec C2 IN 250(11.0mm) 250(11.0mm) 300(12.5mm)
Spec C2 EX 250(11.0mm) 250(11.0mm) 300(12.5mm)
14111-B16-016 VTEC Killer Intake Camshaft (305IN/12.5mm)
14121-B16-016 VTEC Killer Exhaust Camshaft (305EX/12.0mm)
those are the bigger cams toda has.
