Different Intake for vortech but had some trouble
Different Intake for vortech but had some trouble put a Cone filter on the MAF then the MAF to the Supercharger. After starting the car, it ran like crap, surging and such running really rich I could smell gas bad. You think that maybe the MAF being so close to the supercharger is causing turbulance and false readings from MAF? Or do you think that the airflow just changed so much it needs to be tuned?

ahhh.. good point.. I didn't know this. and Good eye by the way!
nope wasn't that. just went outside and bolted the two coils back to the valve cover, did the exact same thing. So I left the coils bolted like I had them and put the vortech intake system back on, and the car runs fine..

I don't think there is any way it's going to idle with the maf that close to the blower like that. where is the bypass?
also why would you do this? all that would do is pull hot air from the engine compartment and cause a loss in performance.

first, you need straight pipes before and after the maf, for best results.
If stock, screened, you should be alright in a location like that... however, your dumping air back into the back of the maf, from the bypass valve, this is the correct place to put it (between maf and blower) , but that close to the maf, most likely has some bad effects on it.
You really need to move it farther away from the blower, for those reasons.
also, i would seriously consider relocating the iat to the discharge tube from the intercooler, makes for a more accurate reading.

im using a granatelli maf, i tried a similiar setup and vibrations killed me, once i dampened the virbrations it leveled back out, it worked, the car ran lean, so i left it alone till i decide to retune

If that valve on the discharge side is bypassing any air, then it's going to run horribly rich and will never work.
A maf on the inlet side must have all the air bypassed back between the blower and maf.To run an open bypass valve you have to have the maf after the valve on the pressure side.
I also think the air filter is in a bad spot, it gets real hot there. I even have my big 4" inlet elbow wrapped in therm-tech wrap to stop the elbow from heat soaking.
Compressing hot air makes the blower work harder,reduces it's output and it will tax your heat exchanger big time.

S_J_H your right, i thought that line was the bypass, but looks like it might be a pcv hose?
too small for the bypass.
Thats the first problem, venting metered air, and then my description, is the secondary problem

I've haven't run the bypass since I installed the supercharger. I've always had the BOV on it. The hose coming out of there is the PCV hose. The reason I was messing with it is becasue well, you never know until you try. Was also thinking of taking the idea further and pulling air in through the cowl somehow. This was just a step in the process.
with n o bypass, the air can only surge back and forth between the TB and the blower.
you need more distance to make it work right, this is probaly part of why you had so much trouble in the past with your setup.

Anyway, if I get a chance I may be playing around with this some more this weekend, maybe a longer tube between the MAF and the supercharger, or maybe gettin a MAF that still had a screen in it..
definately try the screen, combination of the cone filter, and descreened can cause problems for a stock car, let alone a blown car
good luck.
I wish you luck, as i really would love to find a good place for a inlet without using the air lid, so i can use the ati plenum/intercoolers i have laying around for my custom vortech install, but i think it will be too difficult to make it work without much cutting
