Questions about ProCharger P1SC....(many)

[Blown353]

Just an FYI on Procharger's SBC power steering brackets:

They're junk.



The Saginaw (large style) mount is OK but on the flexible side.

The outward mount remote-reservoir style without an idler (uses a swinging bracket to tension the belt) is WAY too flexible and you'll squeal the belt during low speed steering from bracket flex.

The inward mount remote-reservoir style that uses a backside idler for belt tensioning is bad news as the idler pulley bends the V-belts the wrong way and you blow up belts every 500 miles or so.

I know all of this from experience... been there, done that, blew up several belts, finally built my own bracket and things have been fantastic ever since.

As far as noise levels go, personally, my P1-SCH was louder than I liked but several guys who have built quite a few Procharged cars said my headunit was one of the quietest they had ever heard. It wasn't annoyingly loud but you always hear it. Luckily once at cruising speed it blends in and almost goes away. It's very noticeable at low speeds & idle though when you don't have a lot of road or wind noise to cover it up. I actually like the gear whine but I like it very subdued, I wish Procharger could come up with something with a very muted whine like a Vortech SQ series.

We'll see what it sounds like when it comes back from ATI, I recently had to send it back for a very leaky high speed seal and it's coming back upgraded to a D1SC.

Looking at your combo, I would suggest headwork (spend some time on the exhaust side of those TFS heads) and also change to a Victor Jr. or other small single plane, it will have better "on boost" mixture distribution than the RPM Air-Gap will. I ran an RPM Air-Gap with my Procharger for a while and there was a noticeable plug to plug difference. For headgaskets I highly recommend MLS type gaskets. As far as your carb, completely disassemble it and inspect it. Barry Grant is infamous for leaving burrs and aluminum chips in their billet metering blocks and in the carb body & air bleeds which can cause you all sorts of tuning & driveability problems. I've never worked on a Demon that *didn't* have junk in the metering blocks right out of the box.
