Hello.

It is being long since I looked for leaks into my D1-SC Procharger system. I got rid from the hoses and went to pipes, swaped the connection, swaped the clamps, 3.4 in pulley, ChevyChad pulley mod, new boost gauge (just in case), new bypass valve, etc

A year ago, I spoke with the Procharger guys, and provided them with my serial number, and they told me: "Rodolfo, you got the right turbine, is a D1-SC for a LS1 F-body", so I went, "ok", I have to keep looking somewhere else... Build a cheap leak tester, and see whats going on... Well, today while swaping the bearings of the belt tensioner pulley, I took a close look into the compressor unit, and the impeller's rotation looked exactly the wrong way, as I have seen on some threads around this forum.

Look, and comment, please:









I tried to look for a threads, where some of guys had the same problem, and only found one, but the most important is where one of them shows pictures of the "before" and "after", on the impeller subject, of course.

Man!! I could swear I am right, but please, those that know, share your opinion.

Bob (@BruteSpeed), please, what do you think?

Thanks a lot for reading...

It might make a good vacuum cleaner ?

Exactly the opposite!!!

Haha! Pretty much! Because I have been looking for 10 psi, a no matter what, all I get is 4.5 psi.

Thanks.

I'm amazed you're even making that much !!!

What rotation is the actual unit ? does it say anywhere ?

ie, is it just the wrong volute, or the wrong impeller ? And where was the unit sourced from ?

MMM! I do not see on the blower something about rotation.

The unit I got it from an ex-sponsor... With a horrible costumer service. I had a lot of problems with that &&&@@@€! But it is being like 4 years since that.

Before building my 383ci (2 years ago) all I wanted on the 346ci was 5psi, but with forged motor 10 psi and its persue, is where all my nightmares became true haha!

Thanks again.

All I have to do is swap the impeller? Do you guys think that Procharger would sell me just the impeller??

Sending my compressor from Mx to USA and back is gonna be 500+ USD, only on shipping...

Suggestions?

There are companies out there who make/sell impellers. I doubt Procharger would sell you any parts to install yourself though.

928Motorsports and Superchargerrebuilds.

What sort of quality they are, who knows.

You need to establish if the impeller is wrong, or the volute is wrong before you start changing anything. The gears inside would be turning the wrong way otherwise, which may affect their reliability.

The direction the outlet is facing tells you what direction rotation will be. Yours would be REVERSE rotation. If the outlet was facing opposite of what you have, then it would be STANDARD rotation. You just have a STD. impeller in a REVERSE unit.

Look at this D1SC in this for sale add. It is STD. rotation.

Wow, you finally found the root of the problem after you found you had a cracked intake manifold, etc... What a long journey you have been on. It seems that whoever you bought it from swapped impellers! I too am amazed it made the boost it did! ProCharger does not sell the internal piece parts, but as stevieturbo has mentioned, there are places that do. Bob

Sucks to hear that you got screwed over with the blower from an old sponsor. I would think that if you had a receipt or some kind of documentation that you're the original owner, you would be able to have Procharger help you out with a correct impeller.

On that subject, I wonder how well the other options work compared to the factory Procharger impeller.

He had to have bought it used. Bob

stevieturbo

Again I would say, he must find out if the gearset/internals are set up for CW or CCW rotation. I highly doubt both units use the same gears inside ?

If they were straight cut gears inside, I'd say it probably wouldnt matter. If helical cut, very likely it does matter.

It could be the wrong impeller on this unit, or simply the wrong volute.

You are right, Procharger will not sell me the part I need... But, after I spoke with them, Billy, one of the guys that works there, offered me to replace the impeller for the right one, and check everything is ok, free of charge, where all I have to do is pay the shipping "to and back". Really happy with the support, wich I appreciate big time

Based on my perspective I think that the only thing wrong is the impeller. The rotation is accurate, based again on what I see, plus the fact it was putting 4.5 psig.

I will send the turbine on wensday of this week

Thanks lot bud.

Hehe!! Thatīs right my friend... Finally hehe!

As I mentioned to Steve, Procharger is going to help me out with this mess... Something that speaks of a good customer service, almost as good as the one you offer my friend

Thanks a lot for everything buddy.

I do not have the receipt from the transaction back then, but lucky me, I registered my compressor at Procharger's data base,which I think helped.

Thanks for your comment bud.

yup reverse rotation at 10 oclock. that one prob came off a vette or something. glad you got it resolved friend.

The most frustating thing, is that I paid for a F LS1 kit brand new, and I got more problems than I want to remember!

That is great news that ProCharger is going to take care of it! You're welcome. Thanks. Bob
