The shop that is doing my install of the D1SC is almost complete. When I was looking over the install, I noticed that the intake filter for the supercharger was very low in the engine bay. Almost as low as the oil pan!! This looks like a bad place for the intake fitler, especially if it is raining!! What did you guys/gals do to yours to keep it from getting water in it? Also, did you run a filter on your blow off valve? Thanks!

 

Yes thats the proper location for the Filter. And yes there should be a tiny filter on the BOV. Try and not to hit any puddles. Or buy yourself a Dialy beater

 

It obviously requires some custom piping, but the best location is as high and as far away from engine heat as practically possible. The space in front of the driver's side front fender area works well for a lot of people.

 

If you have the MAF down along with the Air Filter in front of the left tire, you're inviting water to ruin your day.

Make sure the MAF is as close to the throttle body as possible (pressure side). If you are experiencing water in on the air filter, then build some shielding (aluminum flashing works dandy) around the air filter to keep it from getting splashed.

If the MAF gets water on it, it's gonna buck and spit and die.

 

I agree, it is a poor design, but it looks like it would get cool air where its located. I will have to reroute it after I get her running.

What did you guys do with your BOV? It is even lower than the filter and is just there I saw a pic on EPP's website that they had ran a hose from the BOV to the fender well. Is there any need for this? There shoud be constant pressure on it at all times, and should never see vacuum.

 

Still running an OBD2 D1 Procharge on a 383. I use a large spearco (behind the air dam with air scoop - 25x3.5x12). I use two (2) evo (bosch type) bypass valves that recirc air back to the procharger inlet. I tried dumping the boost (to atmosphere), but, the engine fueled way rich (with OBD2 PCM in closed loop mode) with running the MAF on the intake side. Still run it on the intake side, but, I must re-enter the bypass air to the blower intake. The MAF stays cleaner on the intake side. I have removed the PCV and run a Vac pump on the crankcase now. Result... No oil mist pumped thru the MAF. Hope this helps. B
