CFM+ intake manifold pics

"Huh... ...



No comment on the pic of your product blown to pieces???"



sort of what I was thinking, so what are these made of? I know you can break damn near anything if you try. Still curious what composite is used?

 

[Rams-n-Hogs]

First I would like to say thank you to the thousands of diesel truck owners who are using our products. It has been extremely rewarding to see how those who have purchased our intakes have understood that the CFM+ is the most advanced technology for the application and achieves the highest and coolest flow. The Diesel market is in for many more exciting advancements in the next few years and our patented leading edge technology will be a bigger and bigger player. We strive for the highest quality and all our CFM+ Intakes are MADE IN THE USA.



Finally I would like to let you all know we still do not have a single (0) warranty claim.



Thank you and May God Bless America,



CFM+

Thanks for responding to this thread. I have one of your manifolds, and I like it, but after seeing some of these threads, I have some questions for you. Have these manifolds been pressure tested, and if so, what kind of boost pressures can they handle?



What kind of material is it made of?



Will water/meth, or nitrous have any adverse effects on it?



Thanks.

Ever been to a drag strip and seen stuff grenade? I'm sure that may be the case , but we don't seem to know much about the situation, just a picture.

Urban legend?

I just thought it strange that the company hasn't addressed the pic that has had over 2000 looks on this site, and who knows how many somewhere else?



I'm one who has been interested in the product, but am now "nervous". Surely, I'm not alone, and to me this would warrant a response and attempt at damage control whatever the result. Just (apparently) ignoring and hoping it will go away won't cause me to reach for my Visa.

The CFM site mentions nothing about a warrantee, is there one? what is it?

 

[hdtrukn]

Alot of HYPE !

Just go ahead and buy one.

How many II or HTT turbo's have died.

How many HPVP have not lasted very long. Trany's have come apart.

Everything is breakable. If you think not send it to me I will break it on the street.

Just my thoughts. And no I dont work for CFM.

Didn't they mention they have had zero warranty claims? If that blown part were mine I would be claiming warranty... unless something else caused it to fail... .

 

[BHolm]

I agree it was addressed, though not very well. How hard would it be to build a test rig that would pressurize the intake until it does blow, or at least survived 100 psi or so?



I don't put much stock into that pic but, I think some more pro-active damage control would be appropriate. How much can it take? How does nitrous affect it? How about heat cycles from the grid heater, what precisely is it made from? Lots of questions, no answers.



I love mine, no problems, see's 40 psi all the time and lots of hot/cold temp swings.

 

[p-Bar]

It was tested with burst to 100 psi .

at what temp? I like this intake but would like to "lift the veil". CFM needs to be a bit less vauge on their info about tests and warrantee. IMHO.

I don't think underhood temps get high enough to compromise the manifold. Most of what I have seen pegs high underhood temps at less than 150 degrees.



Hopefully they do produce some rebuttal. Anything less is going to harm their business. I have to agree with an earlier poster who mentioned glossing over this isn't going to make him reach for his Visa card, Amen. If I didn't already have one, I might be thinking twice myself.

150*? I've heard claims of more than that from the inlet to outlet of the intercooler! Turbos can hit 1000* easy and the cooling system is regulated to 190*, I would have to think air temps underhood are closer to 250* and charge air temps higher than that on a hard run.

Turbos on the exhaust side get that hot, intake air is nowhere near that temp. You need to consider a lot of air flowing through the engine compartment at speed too. Just because the cooling system reaches 200, doesn't mean the surrounding air is that hot. I took my number from a test somebody did on the road, under load, pulling a 6% grade. It is in the latest TDR mag. Maybe I am wrong but 250 seems really hot.

I've done lots of underhood air temp samplings due to another related issue I was experimenting with - and while down-the-road underhood temps at speeds above 30 MPH or so WILL typically stay within 10 degrees or so of outside ambient, once the vehicle is stopped and parked, temps rise (heat soak) dramatically - easily pegging the probe I was using at 150 degrees.



On a hot day, especially in hotter southern climates, I have little doubt it can well exceed 200 degrees, due to radiated exhaust system, turbo, etc, adding to hot sun on the hood. That's the reason some of us suspect heat damages sensitive solid state electronics items in the VP-44's, ECM's and PCM's - and why a few of us have installed forced air cooling to the VP-44, which seems most heat sensitive and failure prone.



When it comes to gadgets installed underhood, it's undoubtedly best to plan that they WILL see frequent temps in excess of 200 degrees - if not while moving, probably at engine shutdown.



Of course, in this case, perhaps the primary concern is intake tract maximum temps - and I would further suspect that a hard pull up a steep grade in a towing situation would also get intake temps pretty well up scale...



Have to do some more temp probe tests I guess - this issue has surfaced before... :-laf

GARY, BHolm,- I just went back to that 05 thread and it was said near 150* was obtainable in street conditions, THIS one failed on a HARD juiced dyno pull. And the temp I'm really concerned with is the charge air temp running through the intake horn itself under 60+psi, or getting quickly cooled by NOS/METH injection.

 

[betterthanstock]

If they tested it to 100psi , and it's a plastic, it's not enough. Plastics need a safety factor of 10 or more, if you want them to survive for a few years, so a bursting pressure of 500-700 psi at 200 deg. F would be more appropriate. Steel can be pressurized within half of its bursting pressure, so steel only needs to hold about 150 psi, and aluminum, more like 300-400. I'm sure the factory elbow would have no problem at 400 psi.

One thing is for sure, if I were running 60 psi and water/meth/NOS, the CFM+ is not the intake I would be running. Isn't that just common sense? Is CFM+ claiming this thing is intended for that type of use? Kinda hard to know when they keep such a low profile here

 

[hdtrukn]

From what I understand that intake came from a 450hp truck running 60psi plus ?

Kinda makes me think.

Makes me think too..... whose 60 psi truck makes only 450hp?

Someone with a boost fooler?
