I am very please with the Bladerunner.........

 

Well I'm waiting to see what CFM does for me. Mine broke off base (not broke the base) went in 3 pieces now I have 2 dents in hood and tore the heck out of my insulation. They don't like 3 nozzles of water off 220 psi pump and a pegged 60psi guage so I beg to differ.

Installed Glacier intake couldn't be any happier. Nice piece. With that and grid heater delete with only smarty tnt-r on 2 I can peg 60psi guage now.

 

Also I didn't want something with bolts going threw intake (were boost flows)
1) for turbulance 2)I've always been told and belive that since they have to have O-rings of some sort they always leak after time.

 

I Have The Ats Arc Flo And It Works Great. I Also Have Water/meth And Compound Turbos. I Hit Close To 65psi Of Boost, Everytime I Am Racing. I Think The New Banks Intake Would Work Really Well. They Have To Machine Your Head To Mount It. It Will Create Equall Pressure, Instead Of Just At The Front.

 

Yeah, but have you seen the price on the Banks??? Whoa

 

part of CFM's warranty:



"This warranty is limited to replacing the defective
Intake without charge and Fastcore LLC shall in no event be responsible for consequential or special damages."


that is if you hadn't used your truck on a dyno, pull, drag, or in coditions that would be considered above and beyond 'normal driving'.
do they sell their intakes tapped for 'normal driving'?

 

Maybe you need to read a little more and not just on DTR!There are several cases of the CFM not holding up on heavily modded trucks.Granted this guy is not at this pont yet but who knows a year from now where his truck will be.If you are going to get an intake horn get one with no reported cases of failures.

 

Ya, I figure I'm screwed on hood and I'll be lucky to get my money back. Piece of junk. (at least it is now)

 

I read plenty, thanks. Forums tend to breed hysteria. The cases of them blowing seem to have more to due with rapid temperature change (tons of N2o, high pressure water meth, etc) combined with a lot of boost. Just like with anything else in the truck, if you stress it enough, you'll find a flaw somewhere.

The GDP, as I mentioned earlier, is a great choice as it tested in 2nd place and its significantly cheaper. As a piece of steel, it won't likely be the place you find your next week spot. Can't go wrong with either, but if you have concerns about massive boost or massive temp changes...save some dough and get the GDP

 

Mine is great...i felt a very big increase between 1400-2000 rpm...right where im always driving

 

I was curious about this intake exploding thing, so I picked up the phone and called them to get some more info. Here's what I found out.

They test their intakes in-house using a water hammer test, up to 110 psi. If you're not familiar with the water hammer test, it basically fills the cavity with water very, very quickly -- as in a lot quicker than a turbo can light--, up to the specified pressure. When I asked at what pressure they found them to begin breaking, the guy said they don't know. They have yet to have one rupture or even crack on them during testing at 110 psi. He did say though, that he wouldn't reccomend runnign more than about 50% of that pressure through there.

As for the exploding intakes, I was told the only one they have ever gotten back was the one that blew up on the BD dyno, and there was evidence of external damage to that particular intake. Where the damage came from is anyone's guess & speculation, but it was a contributing factor to it coming apart.

Right or wrong, it's up to you, I'm just passing along info.

What I do think though is that if there really are a bunch of CFM intakes breaking, send those things in to them and let them have a look it. The CFM obviously flows more than the others (thank you to Erik for that dyno test), but if it's only weakness is a possible strength issue, at least give them some evidence of failure to examine and improve upon. They can't fix it if they don't know where it's breaking and under what conditions it's failing.

Just my two cents.

 

I like the GDP. It won't break, and I like the conservative look. That said, I agree with several posters that none of the intakes make much of a seat of pants difference. Turbo/turbos, trans work, lift pump, injectors would be before an intake horn on my to do list.

 

2 yrs ago when the CFM came out, I call and talked to the guys that designed them. We talked on the phone for a good hour about the intake. I asked why they didn't put and ports into it and was told.... " it wasn't designed for race, and/or high hp trucks " This is from the designer.

Since then I see they put ports in them probably due to a high demand of requests. They may have also create their plastci with a little more integrity than they had initially

I do think it's a great intake and I don't think there's been a lot that have blown. It's a risk you take on your own though....It's plastic.

With the psi, heat and stress some put on these engines.... IMO, plastic would never been the way to go.

For a basically stock DD... it would work great. But then, why even spend that kind of cash on a basically stock truck when the stock intake is complete efficient to over 500hp ?

For any intake, the cash to hp gain doesn't make it worth it one bit. I'm not at all bashing everyone's intake, just stating the facts and letting some know if they're looking for improvements in hp or mileage.... that money would be better spent elsewhere.

 

Joe Hellmann @ www.hellmannperformance.com makes some awesome intakes. I have done quite a few of his mods and hopefully soon I will take some pics.

 

Great input folks! As far as whether or not they are worth it.. Check the dyno graphs. They may not do much for the top end, but the midrange ---where people are towing--- is dramatically improved. Also, on smokey trucks, they do help clean them up a bit. Just something to consider.
