How much do you guys thing that thing would cost? 8...10 thousand?

not nearly that much. now to make it work with an LS series motor.... thats a good ballpark figure since that blower is made to fit a different style intake manifold

lol, all jokes aside it can be done. itll cost you. and would not be as good as going with a turbo or even centrifugal. new roots type blowers are WAAAAY more efficient using basically the same tech. and the twin screws dont have nearly the surging problems.

why would it not be as good? positive displacement blowers are more efficient than negative displacement blowers... (if you can keep them cool)

More to your questions, I imagine a BDS or Weiand would look just fine there with Enderle fuel injectors and a hat. I don't think either of these companies make large 6-71+ sized blowers with manifolds for an LS-engine but I haven't looked that hard. You'd easily be able to find a Magnusun, Whipple, or Kenny Bell that would get close to poking a little out of the hood, but not like that. They'd be a lot more efficient than those old BDS or Weiands though...

To each his own

custom sheetmetal intakes have been made for the -71 blowers to mount to a lot of different types of motors, but it isnt always cheap. they have made advancements in the actual blowers themselves over the years. they arent exactly the same as one you would find back in the 70s

To the OP, Unless you wanted to do $20,000+ dollars of work to your car this will never happen. That is a supercharger for a carburated engine, of which the LS3 is not. You would have to disconnect prettymuch all electronics and drop in a new smallblock (L98 class, maybe LT1 I don't know if they made these to work with that) to run this. As well you would need all new gauges etc, the manual transmission might work with a different bellhousing, oh and of course cut a hole in the hood. Aside from the fact that is most states due to the car being so new it would be completely illegal to register and drive on the road, you would have a drag car only, that honestly probably wouldn't go fast enough vs the stock LS3 to make any of this worth it.

I'm not laughing at you, you said yourself you don't know much. Someone just needed to tell you, it will never happen.

the blower in the picture is not just for a carbureated motor. used to be, but many a man has run a throttle plate or fuel injection with that blower. and the LT1 is not made to run with anything... damn things...lol (yes I own one and they are....fun....)


tho I do agree with you that it would not be worthwhile to even try to make an 8-71 blower run on an LS motor. I doubt it would take 20k, but it would be expensive due to the belt routing, fitment issues, plumbing of the whole system, etc

Wow...just ran across this thread, and I'm kinda surprised at what I'm reading.

First off - the blower in the OP's post is EXACTLY that - a BLOWER. They were called that because they were ALL originally designed for and used almost exclusively in Detroit 2-stroke diesels. They were called blowers because their job was to blow air into the block's air passages on those diesels, like the 6V53T - one of the most common engines these blowers originally came off of. When used in the context of a gasoline motor like in the picture above, they become a supercharger.

They are not as inefficient as most of you are saying in here. If they were so inefficient - why don't Top Fuel cars use Prochargers??? I actually HAVE an 8-71 blower sitting on top of my 502" BBC in my 1969 SS Chevelle. She is street driven, street tires, full exhaust, pump gas, and has run a best of 9.29 @ 138 up here at altitude. That's like mid-8's down at sea level. That's driven to the track on street tires, on pump gas, straight through tech, into the staging lines, and blasting off a low 9-sec ET. Yes, they are MT Street ET tires.

Additionally, you can get a complete setup like what you are seeing for HALF of the cost of a comparable supercharger that will put out the same amount of power. And sorry - but you guys that think this wouldn't look right on a 5th Gen Camaro...well, I don't think ANY car (well, almost) would look bad with a big 'ole 8-71 sticking up through the hood. I think a 5th Gen would look utterly AMAZING with an old-school blower.

Then there's all the stuff that you guys are saying about the electronics. You're so dead wrong. All the sensors, electronics, everything - will work except for ONE...the Mass Airflow Sensor. But that's easy to get around by anyone with a little tuning experience to convert the car using HP Tuners or EFI Live to a speed-density system and tune out the MAF sensor altogether.

The surging you sometimes see/hear on a car with a blower/carb setup is caused by guys that don't know how to tune their carbs for a blower. You gotta adjust the air bleeds differently when they are sitting on top of a blower that's sucking air even at idle. Then there's also removing the power-valves and jetting the carbs square (the same size jet at all four corners on each carb, and running a plug in place of the power valve).

There wouldn't even be any fitment issues because if you run a long-snout blower, you'd clear the stock serpentine drive on the LS3/L99. There is PLENTY of room from the front of the timing cover to the radiator fans. Cutting the hood - well, I wouldn't cut a stock steel hood - I'd just get a fiberglass hood from Harwood and cut it out for the blower and injection hat. You would hafta cut into the cowl on a 5th Gen, and you would lose the passenger-side windshield wiper - but guys that run the Holley EFI Tunnel Ram on their Camaro's gotta do the same thing.

Of course, you gotta build a motor for a blower if you wanna do it right - you will need to have a fully forged rotating assembly to be safe, and you'd need some serious seat pressure on the valves with new springs. Cam has to be for a blower motor, exhaust up to par, etc. But these are all things that you'd hafta do for ANY forced induction setup if you wanna do it right and want the motor to live at boost levels above 5-6 psi.

Sorry if this post pisses some of you guys off - but the majority of you are dead wrong. And besides, if the OP wants to dream a little - why kick the guy down?

OP - if you still wanna know how to do this, PM me, and I'll be happy to tell you exactly how to do it, and what you will need. And it won't cost you anywhere near as much as getting a F1 Procharger or twin turbo setup.

BLESSINGS!
