Howto sell our products. We rely on information and word of mouth to sell our products. If we screw up we are out of business, We don't have two page ads in every magazine out there so how you like our products makes us or breaks us.
I usually tell it like I see it which has earned me more than a few enemies, but has also earned me business. Usually when I release data, it makes people that have bought sub-par products feel stupid that they were taken by hype marketing and a bunch of thugs in flat bills slinging part based on "just trust us yo" it is perception based " we got all of the ads in the magazines so you know we know what we are doing" Plus "this one guy ran our stuff and he has a bad-ass truck eh".
I hear a lot of people saying that you must run a 1.5" CR tappet. this is not so!
On some of our grinds the 1.1" 12v tappet is a little too close for comfort in terms of side loading so we require the 1.3" on any of our custom grinds regardless of year. They will also weigh less. The only time when this is not the case is when you are running a 1.250" 6.7l cam. using a 1.3" tappet is too close, run the 1.5"
In all other cases using our cam the 1.3" is sufficient and weighs less than the CR tappet. Did I mention it will reduce mass in the valve train. This will help stabilize the valvetrain at higher rpm without additional spring pressure.
Think of a contact patch on a tire a taller tire will give you a little bit more contact patch because it has a larger circumference but mainly to get contact patch or more surface area you need a wider tire. This same thinking applies to cams. We run sharp nose angles to accomplish what we need to do which slightly decreses the contact patch at its narrowest region. What we are trying to accomplish for safety sake is more contact patch. since the 1.3" lobe hangs off of both sides of the cam lobe going wider will not help. YOU NEED A WIDER LOBED CAM. that is the only way to get a wider contact patch, more surface area for an oil film and the ability to run more aggressive ramps and more spring pressure without damaging the lobe.
OUR cams feature a 1.040-1.050" lobe width. compare that with a .711" to .850" for 12v cams and just under .940" to 1" depending on the casting of the 24v(except 6.7)
Why are people paying so much for cams that have narrower lobes, sharp angles due to regrinding with small base circles and exposed softer layer of lobe surface? It is beyond me.
The only other way to protect the lobes more is to have a larger surface area with a harder lobe, less prone to deforming and oil with a better film strength(zinc additive).
Don't keep giving money to people that will not give you specs, they are only masking their own ignorance, and if you buy from them you are showing yours. (yes I have a chip on my shoulder about this)
If they are not willing to discuss any of this then what makes you think their product is any better than the next guys hot cam of the week. Data, specs., and dyno sheets etc. is the only way to quantify how a product compares to another...period. You can't copy a cam by knowing the .050" number and the lift. The excuse of we don't want our cams copied so we don't give specs is insane!
Think of how many of the, I don't give specs out on my pumps, injectors, hx55s, cams, springs, heads, pistons etc. have gone out of business. Wonder why?
Let's keep diesel motorsports moving forward with more power and less smoke, not ignorance
