Default In need of rebuilding my D1SC Procharger, options?

Hey guys,

while I have my car apart for an engine rebuild, I noticed my D1SC internally leaks, and there's slight play in the impeller. I figure I'd take the time to have it rebuilt. Does anyone have a how to for this specific unit? I've tried contacting Procharger via email and phone calls to get a quote to rebuild it, but I either don't get responses or can't get through. I'd want to replace all the bearings and seals to be on the safe side. While googling it, I found a place called 928 motorsports that offers their services to rebuild it, and it seems like a fair price too. $517 to rebuild it, parts included, and $36 to ship it back. I'm not opposed to doing it myself, but I haven't done it before either. Thoughts?

I had one that needed rebuilt a few years ago. Sent it in. They charged my like $1500-$1800 to rebuild it . I was not happy about that. Obsoletely ridiculous I thought.

Good lord, that's over 3 times what 928 is asking for. Was your case spent or something?

Procharger rapes you so i don't even bother. I've rebuilt my F1a before after completely trashing the internals and have had it apart plenty of times after for inspection. I have sourced all bearings and even have a spare impeller and gearset lol (custom made).I dont even bother with their oil either, just royal purple motor oil has been working perfectly. Nothing special about prochargers and thats a fact. The 928 price is good if they are using good bearings that are rated for the rpms and the proper impeller shaft seal.

Silver SS, I'd like more details about your rebuild. I too have an F1A, and when/if the time comes, I'd rather rebuild it myself than sending it in. Care to share your source for the bearings impeller and gear set?

Cheapest way: The output shaft gear can be had by the superchargers rebuild guy on the web. I had him make an output shaft for me. He has a few spares. The input shaft gear i had made locally. For bearings go with the jon bond guy along with his output shaft seal. He uses good bearings and the seal is better than others. I have a local source in houston for the bearings but keep in mind, they are sold in pairs when bought this way. Impeller can be bought through jb. Its easy to rebuild if you have a cheap press, a jaw puller for the bearings and an impact. The only tool you will need to fab yourself is a tapered collar used to slide the output shaft through the seal. Lots of info on google if you want to diy.

Some of the prices look fair, so right out to lunch. But, options are options.

It's definitely more expensive, but it seems much more "legit" and they seem to be more familiar with rebuilding these units and higher end parts. Plus the standard 6 month warranty is a nice addition, and the optional 30 month warranty would be useful for extra piece of mind, and possibly a good bargaining chip if I were to trade my D1SC for an F series should someone be willing to do so.

I also found the custom impeller on JB's website, supposedly it flows more air than stock, and could be a useful upgrade. They say you can "trade in" your stock impeller and get $250 back for a good condition D series impeller, so this upgrade would "only" be about $500. Maybe I should just upgrade the impeller and completely rebuild the D1SC and keep that setup instead of trading for an F series. I'm keeping my stock 6.0 displacement, mild heads, meth and most likely stock intake. I don't think I'll "need" an F series anytime soon.

Very interesting that they state their impeller outperforms the factory Procharger one.

Might be worth experimenting.

I know a guy who literally blew up a D1sc aftermarket impeller on the dyno at ~850whp and it was like a grenade. thank god nobody standing next to it or would have been horrific injury. I have no idea if the same aftermarket impeller as the links above though.

i called procharger for a d1 rebuild and if you want bearings or need a new impeller done it's basically cheaper to just sell your old one to someone who wants to rebuild it and get a new one. so nuts what they charge. google work turns up more than a few bad reviews for the other options unfortunately.

seems hard to justify buying a d1 when f1a94 or something is same price.

I've rebuilt my P blower. I used bearings and input seal from NAPA. The impeller seal is special and I got that from superchargerrebuilds.

I have to be honest, the impeller for the F1A has me intrigued.

I forgot to update this thread.

I decided to ask a reputable machine shop locally to see if they've done it before, and what they'd charge to do it. If there's a decent savings with quality parts, I'll get it done there. Otherwise I'll send it to jonbond. The prices are a little high, but they seem to stand by the work, and I like the piece of mind. Plus it'll help if I trade it for an F1A, or possibly sell the procharger kit and go turbos. Which could roughly cover almost half the cost, or more.

Thanks for all the input guys, I appreciate it.
