This pizzes me off! Who is CP performance trying to kid
 

Revolutionary cams that prevent reversion Hallelujah! errr wait only if you use full offshore headers
Didn't the OSO membership figure this out years ago?

Here is a suggestion for CP, dont try and scam the uneducated to buy cams and exhaust when they simple need to buy exhaust with tall risers and the water introduced later in the stream

http://www.cpperformance.com/c-1501-...sion-cams.aspx

Bold marketing...but what else is new in this day and age.

BTW: In case no one knows, I'm the Famous French Male Model from The Internet. :poopoo:

Oh sh!t, another thread about cams, exhaust and reversion. Don't get me started! See guys, it's not just me starting them. :party-smiley-004:

SB, thought all those French male models were, ahem, left-handed batters. Not that there's anything wrong with that!

When are they going to make me a cam that will give me that 3/4 race cam idle that I can use with my silent choice setup? :lolhit:

Not quite sure why someone marketing "anti-reversion" cams would anger you so.

I don't see why it's wrong for cpperformance to sell cams designed for the marine enthusiast.

Maybe I'm missing the malicious intent.

if you need it I have a 3/4 cam, ok so its a full cam with 4 worn off lobes but 3/4 of them are still good.

Unfortunately we do our best to sell products to people who understand them. Anti-reversionary camshafts are ground and installed on entirely different principals that traditional camshafts and are great for certain applications. Were sorry that some just balk because they don't understand but we just can't help that.. But thanks for acknowledging the fact that we do want to bring newer technology components to the boating industry.

Keep in mind this is not rocket science and professional engine builders that actually have their own cams ground have used these techniques before. What they most definitely are not is a cam that your going to find in your traditional camshaft catalog. Again all were trying to do is educate those that care about engine technology and those that don't well just disregard it.

you are advertising a cam that eliminates reversion but then have a disclaimer that it cant be used with switchable exhaust so essentially you are saying if you buy this cam you will still need a custom exhaust which by the way is the solution for reversion!
You are using marketing to trick people in to buying your cam as a solution when they still need to buy the "solution" headers
Each cam has a disclaimer "FREE FLOWING EXHAUST IS A MUST" people on these boards have been running free flowing exhausts as a solution to reversion with big cams for years.
This is not technology this is marketing
Are you saying that people running stock exhaust manifolds can now run much more aggressive cams and not have reversion? if so then I'm in!

if we buy a custom exhaust we can run a bad ass cam and there is no need for an " anti reversion cam"

:bong:

Are you mad at holley because you need a good intake manifold to use one of their carbs?

Bent out of shape because you need a performance prop to use your performance outdrive?

This is ridiculous.

i agree kinda hard on paying advertiser too

I thought everyone was taking out their frustrations on johnnyboatman this week......

Not everyone into performance boating is an expert or even has a clue what they are doing....

Is now a good time to introduce my cams that add boost without a Supercharger ?

:lolhit:

Not sure how this isnt clear, saying that you have anti reversion cams but still require custom exhaust is like saying you have a prop design that gets you on plane easier but still needs tabs.
That means that every cam is an anti reversion cam providing its used with the right exhaust?

If the cam was actually an anti reversion cam then it would prevent reversion with any exhaust

Vintage, how do you not see it? how can it be an anti reversion cam if it can only be used with the same exhaust that prevents reversion on every other cam in the available?
Its the exhaust that's preventing reversion not the cam therefore its not an anti reversion cam.
If they advertised that this cam will slightly reduce the harmonic impulses that lead to reversion then it would be an accurate claim.
The holly comparison would be more like "Buy this intake and you will get the performance of a supercharger"! (must be used with a super charger)

Now pass the pipe

They just need to tweak the name its not a big deal:

Anti Reversion Setup

or

Anti Reversion Cam and Exhaust Setup

This doesn't annoy me nearly as much as Hardin Marine buying out "performance hydraulics corporation" , and jacking the prices way up. Used to be able to get tabs and trim pumps very reasonable thru them. Now that Hardin bought them out, the prices inflated way up.

This Just In!
Anti Reversion Headers from Lightening, St.ainless Marine, Keith Eckhart, CMI, (must introduce water near the tail)
Wow what a great product, Anti Reversion Hull's (must be used with custom exhaust that introduces water near the tail or overboard)
This may be small to guys with headers but to us little guys that dont have $3000 exhausts and would like to run a nicer cam this is a bait and switch.

BTW Isnt CP and Hardin the same company?

Dry headers with thru hull water dumps are the 'anti reversion' of 'anti reversion.'

Winnie won't like that..

CP is in business to make money and of the online marine performance guys they always gave me what I wanted for parts and I always went back due to fast shipping. I even had a problem when I bought strainers and they fixed the problem FAST.

Its just marketing... It is everywhere around you from diet pills to McDonalds to electronics. Everybody pushes the envelope....

Caveat Emptor

As you can easily read in my other thread that documents my painful lesson about reversion, there are a lot of factors at play that determine if a given combination of parts will revert water. Yes, cam design and exhaust design are major factors, but you also have a lot of other factors like engine displacement, crank stroke, rod length, exhaust port design, even intake manifold design that can influence this. Sometimes you can just end up with the perfect storm of factors that will cause an engine to revert when at first glance you would never dream about it.

This is a great comment and exactly why I feel like this add is playing uneducated people like me for fools, buy this cam and you will have no more problems, bull crap

anyway I'm off my soapbox, need to place an order for billet parts at CP and go boating

cheers


ANyway its the weekend and time for boating cheers everyone im off my soap b ox

You cant be serious!!!!!!!!!!!:party-smiley-004:

not about the cams but on the same track of deceptive marketing,,, bought "hardin marine" manifolds from cp,
turned out they were glm's , stamped glm on the side..
Nowhere on the site did it say the hardins were glms.
one leaked internally and hydrolocked my just rebuilt motor second time out..
only thing cp did was give me number to glm and washed their hands of it.. Wont ever use them again or recommend them.

The cam is ground with characteristics that minimize reversion.

No smoke and mirrors, really.

You put a performance cam in a boat to increase performance not prevent reversion. Reversion is a side effect of larger cams and steps can be taken to mitigate the reversion (steps like using cams like the ones from cpp or bob)

The best way to eliminate reversion is to use a "dry" exhaust.

This stuff all woks as a "system" and as such, several components may need to be upgraded if you start to change parts. Such is the case with "hot" cams in boats.

Pretty simple, really.

Thread seems like a cp performace
Bashing thread now

Took a turn for the worst.

Yep. It's crap like this that alienates the aftermarket from participating on forums.

Don't get me wrong, if there is a real issue or concern, by all means, air it out.

Starting a nonsense thread for the sake of generating online drama is weak. :argue:

Agreed 100%

Only gonna get worse.

Although some badgering here, The good news for them + us is that we all need them to be around. Without them. most of us wouldn't have 1/2 the stuff we have in our 'personalized' boats.

I can tell you this...somebody with the cam designing ability (Bob M) can in fact design such cams, you would be surprised at the games can be played with camshaft design, ever heard a NHRA stocker these days with a "stock" cam ? Bob spend many hours playing with out Turbo LS cam setup figuring such thing as comressor housing, manifold design, distance from exhaust valve to turbine housing..etc ...etc...so that being said someone who sat down and started designing with the knowledge of what they wanted the engine to do at whatever RPM..no doubt can be done...so before you throw the B/S flag..do your homework...

You can't make an exhaust system do what it can't do....and the great part about Bob M is that he understands this and convey to a customer what he can do and can't do with the engine power wanted by the customer. The customer may not want to hear the answer, but since it's the correct answer (truth) that is what Bob M will give.

Those in the HP industry that don't provide these answers (truths) are just another parts salesman and shouldn't get involved with making suggestions and thus be what they really are....parts suppliers.

People like Bob M are head and shoulders above parts salesman because they actually understand what and what isn't needed and if there is a grey area, they'll convey this to the customer while at the same time try to remove the customer from a grey area.

I wonder why the aftermarket doesn't just flock to OSO .Everyone is so friendly when they(cp in this case) try to explain their position on whatever subject......I'm not knocking Bob M...but based on this forum he is the only guy to trust ................I cry BS .....No offense to you BOB M

Many of us use and trust ourselves. Does that count ? It should.

Many of us use a certain builder we've used for years, does that count ? It should. Many builders don't get into national sales, engine and parts sales to be more exact, so thus why many not mentioned on national / worldy forums like this.

So you don't give a crap about what companies like CP can contribute to the industry?

That is not correct at all.

You seem to be under the assumption that big cams won't revert water with high performance free flowing wet exhaust. You are WRONG.
Plenty of people with aggrssive cams have to run DRY exhaust to not have reversion problems.

The cams are advertised with what is required for each one.

CP Performance has been a participant and advertiser on OSO a lot longer than you have been a member and are they are highly respected professionals in the marine industry.
Because of sponsors like them, this board exists and new guy members like yourself are able to post and get your questions answered.

So you bought the cheapest replacement exhaust they sell and you are mad they gave you the name of manufacturer so you could deal direct....Damn

Which core are these ground off of? At that price point if it's not a billet core I wouldn't be a buyer.
