Default H22 Intakes and Velocity Stacks

Im trying to get a good idea of what the best setup for an h22 intake is.

Right now i have a j's racing "whale *****" and i have been reading up a lot on velocity stacks. Im really interested in putting together some kind of velocity stack intake.

A lot of the setups i see are b series, but i figure the flow dynamics will be for the most part the same....just with more volume needed here to feed the H22. A lot of the setups are just short rams with a stack on the end. Jeff at IB said to put the stack on the end of the AEM cold air my friend has all the way down in the fender. I want to figure out whats gonna work best for me as far as:

Whether to use a short ram or the full cold air?
What piping diameter to use?
Stack size to use, im pretty sure the IB one is 3 inch where it goes into the intake
Possibly try to get one made for the J's....some guy did a custom one for his j's, but instead of going over the end, it slid in all the way, and then the regular filter fit over the end. Not sure whether it would work or not that way, considering after the air goes through the stack it is let off an edge to the bigger diameter j's pipe.....

what do you guys think?


EDIT::here are some pages on h-t about velocity stacks FYI...

I would also like to know about this. Is the "magic intake" from Import Builders just a velocity stack thing that you add on to your existing intake?

Thats not really a good idea. A larger velocity stack, like the one you would use on the end of an intake tube as apposed to a ITB set up requires area in which it can draw air from every direction. Its best positioned outside of the car where it is able to draw from adequite spacing (nothing in front of, behind or on the sides). A velocity stack is more or less a vacum draw, it draws air from all around the radius lip.

The actual shape of the J's intake is not really necessary with a velocity stack. Your going to want something that starts out at a 3.5 inch ID and makes its way down to about 2.75 at the intake to TB transition, a cosntant diameter will also work well... The taper is just my personal preference. The actual length and or taper degree will be dependent on your set up/rpm range.

i have seen a few of the intakes that jeff sells.....they look like they do that taper buit i cant tell for sure from the pics....

how adversely is the stack's performance effected by being inside the engine bay somewhere vs being in open air.....and do you think that in the fender or in the traditional short ram spot is better for the stack?

Can it make that big of a difference?

When I went to the dyno at Church Automotive, one the the last things Shawn did was disconnect my air filter, and put his magic velocity stack on it. It made no gains or losses.

The specs for the stack and tube itself play a big part in the function of the intake. Have Joe from Prototype Racing build you one specific for your set up... It will defenitely make a difference

It makes a huge huge difference being outside of the car as apposed to inside the engine bay.

BTW, I have an IB intake, its a constant diameter from start to finish

You would see better gains from a velocity stack if it were outside the car on the street/track... Even fans don't simulate the air rushing through the engine bay at 100 mph...

Yeah, but the AFS system Iceman makes doesnt come close to a velocity stack and a aplication tuned intake system... Even Andy Knight (Iceman/Knight Engineering) himself will tell you that...

so is there any way to use a velocity stack on a street daily driver and get good gains?

Its more or less a track only thing.. Driving with an open velocity stack everyday can, and in most cases, will cause your motor to injest some nasty **** here and there... Dirt, dust, debree, etc, etc

Are you talking about running just a stack ? Or stuff a stack in your current intake then putting the filter back over it ?

we (me and mgags7) were both talking with jeff about this and there would definitely be a filter over the end of it....

i would never daily drive with an open intake....
