I put an after market serpentine belt kit in my 81 is there a supercharger that will work with it, or will i end up having to change everything,again?

Lars put one on a vette even documented it in a thread you might be able to find by searching his post.

Roots style or centrifical? Centrifical mounts where the alternator is located. Supercharger belt should just be for the charger. They don't make a S/C mounting bracket [centirfical] for the C3s that fits under our hood that I've found . Just got done mocking up a V1 on a modified mount to check for the clearances. All C3s that I've seen with Roots style have modified hoods which limit your visibility to the front right, but they sure give some great bragging rights and look so kool!. T

They do limit the viability in the sense that if a toddler were standing in front and to the right of it you probably wouldn't see it, but as far as driving, it really doesn't hinder vision much.

I was running an Ecklers L88 hood scoup to cover up the Elde RPM air gap and could barely see the right front fender. Stock seats. I'm 5'8" adding Corbau A4 seats raised me up, then built a custom hood with a 2" rise that followed the original hood slope. Great visibility now. T

you can't see the front end anyway on these cars. o.k you can with the tops off and standing on the seat.

I have a 6-71 with EFI and the hat only sticks out about 4 inches over the L88 hood. Visibility seems unrestricted but I am 6'2" with A4 seats as well.

Torqstorm makes a supercharger that will mount on the passenger side of your engine that is supposed to clear the hood. Assuming you do not have A/C of course. They were claiming that is makes 6-8 psi boost and costs 2800 for the entire kit. I wanted twin superchargers but they had not finished building a kit when I changed and went with a roots style instead.

Im running the L88 4" high rise it clears the rpm air gap and a 4" k and n by 1/2".

My point exactly.

You got photos?

Sounds real interesting dual superchargers. Twin turbo is were the power is at, so a twin super charger might be nice seeing as i can't see any way to fit twin turbos although Jim did it wit a 555". Thanks for the info I'll check them out. I have a mp122" roots that I'll probably put on in a couple more years.

The engine during the install…still need to finalize wiring before looming them up and mount the gages on the back above the fuel lines to the injectors.





The car is still a work in progress but at least it looks like a car again. The Autofab/Moser M9 rear end kit is waiting at home to be installed in two weeks. Bought some M/T 29x15x15 S/R tires for the rear.

That looks sweet, I asked about your rear diff in the tire section, disregard that. Can you share anything more about your combo?

oops!

Jamess411

It is a 420" SB with a 3.875 stroke and 6" rods. Dart Pro 1 215cc heads with a custom ground crower cam made for the blower and engine. The entire thing is studded and roller with a small bore 6-71 sitting on top. I wanted to run pump gas with the boost so decided to go with EFI and Meth injection to control any detonation possibilities under boost and to keep the timing. Everything not ignition related is Holley with a 6A MSD box and coil to light it off. A Holley HP computer is controlling with a Enderle Bug catcher and 8 60lb injectors feeding the engine. I figured out that the engine only needed 1050 CFM of air at 6500 rpm and 7 lbs of boost so I welded two block off plates inside the hat to make only one of the butterflies actually allow air in. One section allows 1090 cfm not allowing for the extra ram air pressure of the car moving at speed so I think I will be good. If it seems restricted at all I can just drill a couple small holes in the plates to flow more air later on.
There is still a ton of work and adjustments to make before any actual driving will be done and I like the journey and all the new stuff I am learning during the build.
When I get back home in two weeks I can install the rear and new HUGE rear tires to see if my measuring will result in the look that I want. There might have to be some reshaping of the rear flares to line up with the tire stance perfectly but that is a ways down the road.

Very nice combo! What do you figure it's making power wise?

Good purchase.

riarms

I do have ac, it came with the aftermarket serpentine kit

Jamess411

Hoping to be in the mid 700s but the guy that helped me pick out the EFI stuff and cam grind said that is a solid start with room to get more. Everything bought will support over 800 easy so its up to the tuning and supercharger now. It is a huge learning curve to go from moving the dist. and changing jets to hooking up my laptop and just changing numbers. Stiil trying to decide on plastic or stainless for the meth tank.

bluedawg

I would think and hope with 421" and a 671 you'd be a 700. I'm going to put my mp122" on my 400" and hoping to hit 620 to 650ish. I won't be putting it on for 1 to 2 winters from now, I want to let the ring gap open some.

jeg sells a basic centrifugal blower set up for $2500 .

bluedawg

I haven't looked, what make. Then you have to by the blow offs (not sure on the terminology) &if you go intercool'd you you gotta buy the intercooler and piping, but if you got the basic kit and regulated by pulley size and used a little Meth injection. Centrifugal is what I really wanted to go with but at the time I couldn't see how I'd run an intercooler so after drunkin ebay I ended up with the mp122.

Ive got a pro charger D-1SC, which isn't fitted yet, but lead to believe will fit under hood, just had to put alt on other side of engine, having to use steering pump with remote res

so aiming for 900 + at the crank, engine all setup for force induction
