Ive seen the gains on boosted cars, but I do not have any data for the NA combo's although my gut tells me it definitely can't hurt, plus it could save some money... that elbow is pricey.
Every bend hurts airflow and power seen this first hand on the dyno when making adjustments on a class race car (where every little bit counts). You would be surprised how good a 4" rubber elbow and a 4" piece of straight pipe do over ANY of the aftermarket CAI or Power Pipes
To convert over all you need is a FOX EGR (optional), TB, Cable and bracket, TPS, you can reuse your IAC is most cases or you can switch to the Fox IAC. Then you can either fab your own pipe or use an aftermarket piece. If you want to retain your crusie control you need the fox CC cable..
Hey Rick
I'm with you on everything you said here
You got a lot of knowledge Rick and I don't want to make it seem I'm
questioning it or your good credibility you have with us here
Where I have a problem with the Fox TB Conversion is .....
How peeps quickly hop on what seems to be the ....
"Of Course it flows better" ... band wagon
I will be the first to say I don't know for certain
I do wanna point out if things are kept equal in each setup .......
The Fox setup seems to offer a more severe bend than the SN setup
For my 95 GT I run a .........
65mm FMS tb and a ProM 80 meter on a section of 3" pvc pipe
and
Of course ... a elbow to my RPM intake
with
No bends of any kind
Now ... If I did the same thing with the Fox setup ......
the path from filter to tb outlet would be no different
other than
No elbow would be present
but
The rubber tb/intake coupler is at a more severe angle of bend
To my way of looking at it
that more severe bend will offer more restriction to the flow
Also ... The more severe angle no longer allows me to place my meter/filter
in the cool air of the inner filter without using an additional bend
I know all I have to go on to make my opinion here is just an observation
so
I can only say ... by looking at pics of each setup ... if I did the Fox thing .......
I think it would offer more hinderance to the flow ....
for my particular application
