I'm going to disagree on this one about surface area, at least in my case. I tried the 31x12x3" and unless it was some sort of lemon, i had a major issue. For 4 months i had no boost, would barely pass the 0psi mark up to redline. Replaced just about everything in the system except for the IC. Then one day i got an idea and made a vacuum fitting before the IC and guess what, saw 7psi. Installed another vacuum fitting after the IC and guess what, saw 0psi. IC held 60psi compressed air all day, not one leak. But i'm guessing it was a bottleneck in the system. Upgraded to the 31x12x4" and no problems since. Major difference in the two (both made by cxracing) here's a pic-

 

I should have specified 'more surface area' meaning taller (more runners), not wider which will only increase restriction... but yeah get a 3.5" or even 4" core if you can fit it.

I think that 3" core is the kind that everyone hates (maybe they just suck lol).

 

Careful on this on too OP as i experimented with this as well. You don't use a BOV with a centrifegal SC, you want to use a Bypass valve. The blower makes quite a bit of pressure, even at idle, and you need to releave this pressure between the impeller and the throttle plate. A BOV is NOT open at idle or cruise, therefore you have pressure working against your impeller on the blower. A BOV is always closed except when you chop the throttle in boost. MikeGyver is running a turbo setup i believe, so a BOV is what you would use there.

The bypass valve is open on idle/cruise and shuts when under boost/WOT. If you run under 8psi on your SC setup the standard Bosch bypass will work just fine. If your going for 8-12 then the procharger Proflow (what i have) will suit your needs. If your going for big boost, then get the procharger Big Red race bypass valve.

 

Awesome thanx for all the info you guys are giving me

I was unsure of this since centrifugal compressors require high RPM to build any significant pressure. A turbo with a BOV is still spinning at several thousand RPM at idle, but that doesn't correlate into hardly any pressure when dead-headed; pressure just backfeeds past the impeller at low rpm. If the pressure does reach a few psi then BOV will open and regulate it at that threshold.

Roots blowers on the other hand are positive displacement pump and will (ideally) continue to build pressure at any RPM, so (I believe) some type of bypass valve needs to be used here.

 

You would probably be quite surprised at how much air a centrifugal supercharger moves even at idle. Also, don't forget that a blower is linked to the crankshaft via the belt so air trying to go back past the impeller is going to add stress to the drive system and crank snout.

 

I just bought the CRXRacing kit with piping off Ebay- 4" intercooler and 3" piping, with couplers and clamps. Using that in combination with the stock piping that came with the Procharger kit should give you plenty of piping to accomplish what you need.

Some might disagree that piping is junk but it has worked fine for me- all the ends are bead rolled so no popping off.

 

I will look into that how much you grab it up for

i run a CX racing intercooler and pipe also... works great! except i didnt cut the center out of my nose...

 

i was thinking about doin that and putting a billet grill in its place anyway.. it would be tacky to have the red bowtie showing behind it

 

so now it will just have sum function with it

 

exactly what i did, plus it gives it more of a sleeper look->

 

Great now that I've seen that idk if I want a stainless steel look or that black one..I'm going to try and keep my fog lights tho

If you go with the CRX intercooler you will be hard pressed to keep the fog lights. The intercooler that comes with the Procharger P600b will let you-it fits perfectly between the factory foglights, but once you run more than 8lbs boost it likely is going to be a restriction in your system.

I put my intercooler as far forward as I could- and I still had to cut quite a bit into the crash-bumper to get it to fit. The factory fog lights mount to that and once you cut enough to the intercooler to fit there isn't much left to mount the foglights.

Your only option would be to put the intercooler far enough back to allow the foglights to mount ahead of it, but you will be hacking out quite a kit of metal either way. The farther back you put it make your bends tighter- esp on the passenger side, unless you relocate your battery and overflow tank. Also- keeping the foglights in front of the intercooler will be further interrupting air-flow, which some might argue isn't an issue- but I personally don't want anything getting in the way.

 

i bolted mine directly to the bumper...
