Intake Manifolds

[Guezen]

I've been reading up on intake manifolds and stumbled across the comparison of the CFM+, AFE, and the ATS. From reading this I'm leaning toward getting the CFM+ manifold, but I was wondering if anyone has any input on the BD X-Flow manifold. I've searched, but I can't find any numbers on BD's manifold. The reason I'm asking is I have BD's intercooler, down the road I'm planning on a BD turbo, and if it has similar numbers as the CFM+ I'll stay with BD and get their manifold.



Thanks for any advice.

Haven't seen any testing done on that one, looks to me to be another hunk of aluminum (great heatsink) just what you don't want.

Several members do not like the AFE intake. I say go for the CFM unit. No complaints, and a lot of happy campers.

So far the 6. 7 litre engine appears to be ignored by the after market people! OR they are all waiting for the emissions removal schemes to be fully developed and available. I would have thought that anything which would help reduce the EGT's and help the engine breath better would be second on the agenda after easy install engine mounted bypass oil filtration.

Probably waiting for units to be sold. I think the EPA is watching these companies closely

Have you looked at all the garbage plumbing attatched to your engine????I'm not even sure HOW you could change parts out, or even why because the raw exhaust pumped right back through the engine thing is pretty self defeating from a performance standpoint. The crazy emmissions controls strapped to the 6. 7 make mods really complex. If you removed all the bad stuff, then you have codes and such, voided warranty, federal offense for tampering Doesn't see too surprising to me

Like to see a test on the Banks manifold.

:-laf Show me any proof on heat sink effect in that application... ... ... ... ... . I have dynoed at very high boost,no heat felt on the intake during or immediatly after :-{}

The 6. 7 is built to meet very stringent standards,to modify will be a federal offense in the states,too easy to spot,not worth the risk for most owners. Just too small a market with too much risk

Hey BOB 4X4 your AFE is taking a beating here's the link

Bob4x4,

While i have no interest in beating up the Bladerunner (i own one, just haven't installed it yet)--I also have a question regarding my Bladerunner and statements which you have made concerning its design and construction--I posted the question in this Bladerunner forum-- https://www.turbodieselregister.com...ons-2003-2007/192981-afe-blade-runner-2.html; but since this forum seems more current, I am reposting here--

Bob, how can you say that the AFE BladeRunner has no bolts in the airpath??-- aside from the internal vanes on mine being VERY roughly cast, they DO have holes through them that allow the bolts to pass through to mount the intake to the motor. Those holes are not in the picture you posted, but they are still there, which means that the bolts run right through the flow of the intake air. Thanks for taking the time to reply and explain what you meant;

From what i have seen the intakes all makes about 15hp or so on the bottom end but actually make less power on the top end.

My tests indicated that they all (CFM, aFe, ATS) made significant TQ and varying HP on the bottom end, and all made about the same (+10/10 give or take) up top.

Can you please repost your dyno runs on the 3 manifolds?



I tried your link and also tried Trivalleyperformance.com on two different computers and I get the "website not found" message.



Thanks!!

p. s. I have a CFM+ (black w/3 ports) on order from Parleys ...

I think the heat sink argument is a bit overhyped also. Air is flying through that intake and there isn't time for it to absorb much heat even if the intake is hot. My GDP unit never really feels too warm.

 

[Bob4x4]

The boosted air is warmer than underhood temps under most conditions... ... ...

I have the GDP intake horn. Recently after a long haul of about 5 hours pulling a very heavy trailer while checking my oil I felt the horn, it was not hot. I do have an infra-red, guess after the next long haul I will read it's temp just to see what it reads. Boosted air should be a tad bit warmer than the intake air one would think. I have an Ice Box intake, guess I could read the air on the backside of it pre-turbo, post filter/box to get a comparison. Both would be steel and underhood temps should have heat soaked them after hauling.
