ls7 and ls3 head ports are different, and the ls9 blower is made for ls3 style head ports, so head swap would be the first thing. The cost would make it stupid to not just do a heartbeat/Maggie/eforce if you wanted that style of PD blower. By the time you did heads, ls9 blower, new accessories, hood, etc there would be no way it is worth it.

They make ls3 to ls7 adapters. Didn't mention that..
Haven't seen any of the TVS blowers make the 800 900 and now 1000 numbers the ls9 setups have. Also don't see them going 9s in the high 140s either.
Also when you swap acc you get an 11rib belt? That is direct drive style.
still have to add intake,hx pump and Hx...to get power out of them you need to port the heads and blower also...ls3 to ls7 adaptors wouldnt they cause a type of flow restriction?.. then still need balancer also.

No clue?!??
Thought it would be a cool blower project.
Not sure I would do it on the silver car. Already has a lsx block. Going to be too damn heavy.
Just wondering if someone had done it. Seems like a cool project.

Blower can be found for 2500 and acc for 1500.
Not outrageous prices at all I thought.
The little stuff adds up though.
I think the real reason the ZR1 blowers have made more power than just about any other TVS2300 blower is that they've been pushed far closer to their limits than anything else. ZR1 owners tend to have deep pockets, and when you have a factory supercharged car with a strong bottom end, it only makes sense for it to get pushed for all it's worth. Most guys buying a 2300 blower for an LS3/LS7 car aren't looking for anywhere near that level of power, so it isn't surprising that you don't see it.
There are some big power ZR1s out there, but the blowers are heavily ported. They also have ported aftermarket snouts, upgraded intercooler bricks, giant throttle bodies, aftermarket heads, huge air intakes, plus the benefit of E85 + meth in most cases. Oh, and about 20 psi.
Having the wide factory belt setup and lots of small pulley options would probably be the biggest benefit I can see to that blower. I think you could do the same thing with something like the Heartbeat, but it might take some custom fab work to make it happen.
If you can get all the parts for a decent price, it would be a cool swap. I can see all the small things you'd need to actually do it costing a lot of $$$ when it's all said and done though. Just the LS9 accessory drive setup was big money last time I checked.

Why go through the trouble of custom fab work when gm makes a bolt on solution???
Off the shelf balancers, plenums, and acc work just fine.
Zr1 acc drive is only 1499 on jegs.
Blower can be found for 2500 by googling the part number.
Even adding all the other things it seems right in line with any other blower.
Only thing custom would maybe be a pulley if you wanted something wider than an 8-rib.
I'm pretty sure someone has added up the costs of doing this before. Came out really expensive. The Chevy Performance LS9 blower looks to sell for $6k new. Maybe you could find a used blower for $2500.
For what it's worth, that ZR1 accessory drive doesn't include a bunch of other stuff you'd need. Water pump, valley plate, and balancer are a few I can think of. Plus new power steering lines, and possibly A/C lines. That's probably more like $3k.
Then you're going to need a heat exchanger, hoses/lines/hardware, coolant reservoir, coolant pump, and probably a bunch of other random parts like possibly valve covers, intake parts, PCV system, etc.
I think that's the real reason this isn't done. Cool idea, just probably not super cost effective.

I agree with Streetk. I think the "little" stuff on a project like this could or maybe would drive you batsh!t crazy. If you had a wrecked ZR1 to source all of the supporting stuff from, it might be not be such an arduous task. I guess if you had deep pockets full of money, time, and patience...maybe. I agree that it does sound like a neat project. I'd be your biggest fan if you were able to pull it off
If you know the part number for the actual blower. Google it.
It's sold online from vendors for 2500.
The rest of the stuff could be had used or aftermarket. Depending on power goals.
Meaning throttle body and plenum and balancer and such.
The part number you're talking about (12625144) for ~$2600 is a bare supercharger -- doesn't look to include anything. Doesn't look to include intercooler bricks or a lid. Lots of stuff missing. That's why the Chevy Performance blower is $6700 -- it has all that stuff.
Here is a parts list PartsTaxi came out with when this blower was released: Here's everything else you'll need to make it work;
And yeah, you could go aftermarket for some stuff, but you're going to need top-notch parts to make big power. The Vengeance heat exchanger/coolant pump kit is nice, but it's $1350 for a heat exchanger, pump, and some hoses. About the same price as factory stuff. I'd add in the cost of a Lingenfelter snout ($1400) and pulley kit ($450), plus blower porting service.
Just being realistic, not trying to bust your bubble.

I think You are mistaken on the pricing and what is needed.
Regardless. 900ish rwhp isn't cheap. Even at your listed prices it would have been half the price of building the NA motor I built for my c6z.. And would have made more power. And been just as unique.

Those aren't my part numbers or prices. That was Parts Taxi's (forum vendor) list. Look at those last pictures I posted. That's what you get for $2600. You aren't going to do much with a bare blower.
Making big power isn't cheap. I'm not disputing that. But thinking you can piece together a ZR1 blower kit for the price of something like a Magnuson just isn't happening. Then start adding extra $$$ to mod the stock blower.

Would be cool to see for sure.
I'm so deep in my NA build though I doubt I would do it. Just wondering if anyone else had.
My NA motor should make as much power as a lot of guys zr1s though.
Lsx block, 434in, etp heads, jessel rockers, solid roller cam, sheet metal intake, 13.5:1 compression, even has a direct port from nitrous outlet.

No you are mistaken on what you need and what comes with the kits and part numbers.

That was a GM dealer and forum vendor's parts list. I'd say they have pretty decent info at their disposal on what's needed to install that blower on an LS3/7 car.
What exactly do I have wrong? That picture of part number 12625144 was straight out of an online GM parts catalog I use. Same catalog the dealers use when they order parts. It's a bare blower without the intercooler parts, sensors, random accessories, or fuel parts. It would be what the dealership would order if a ZR1 under warranty had an issue with the blower rotors, bearings, etc.
The parts diagram is pretty clear, and Chevrolet Performance isn't adding an extra $4000 to the price of their "kit" just for fun. It's because it's a complete blower, and besides the throttle body and injectors, you'd need everything it includes. No way around that.
Lots of stuff needs to be changed. Yes, the valve covers are different. The stock coil brackets won't work with the LS9 blower. The LS9 valve covers have built-in coil mounting bosses. The LS9 water pump is needed and not included in the LS9 accessory drive kit. Read the fine print on that kit's instructions.... it doesn't include the balancer, the water pump or the valley plate that's needed:
You are also relocating the power steering pump, so new lines are needed. Obviously, you're going to need a heat exchanger, intercooler pump, reservoir, and related parts.
I'm not making any of this up. I deal with OEM parts catalogs for a living. Deciphering this $hit is something I'm pretty good at.

Anyone ever install a zr1 blower??
