I’m thinking of fabricating some 2” stainless steel velocity stacks with 8 separate K&N filter pods for my 6.2L. Do you think this would be a good performance customization for a naturally aspirated diesel?


The way I think is, with a diesel the more unrestricted airflow =the more air in and the more fuel that can be efficiently burnt = more power?


Would velocity stacks be less restrictive than the OEM EGR-less, dual-plan, high-rise intake for the 6.2L diesel?


I also think that the velocity stacks and headers(I’m going to buy from Stan‘s Headers) would make for quite a conversation piece. Don’t you?


It’s sort of like a person buying a Siamese-bore aluminium block and boring, stroking and the whole nine yards, powder coating it the OEM block colour and not saying anything. I would be doing that in a small way because people could tell it was a diesel by the sound but not by looks to the untrained “diesel” eye.http://www.dieselplace.com/forum/smileys/hihi.gif


So what do you guys think, is it worth it or am I just dreaming of irrelevant ways to make naturally aspirated power?http://www.dieselplace.com/forum/smileys/smiley24.gifEdited by: project 6.2L

I saw a link the other day for eturbines. You add a small eletrical motor on the intake and gain 1-2 psi boost. 1-2 psi boost feels awesome compared to n/a.

i don't have any personal experience with those electric things but i have read a lot of warnings that those things are an e-ripoff. when the vehicle is pulling its own air the fan can be more of a restriction than a booster. most of those are nothing but boat exhaust fans for the poo room. on a n/a diesel, without trying to add a turbo, i think a ram air setup would be the way to go. banks has one that comes recommended from a buddy of mine with a '90 k5 blazer 6.2. my approach would probably be a cold air/ ram air system using an add on hood scoop as big as you can get to maximize collected pressure. hook it up sealed to the intake and cut out the hood to fit over it like the shaker box setup on muscle cars. my 2 cents.
