what do you think of supercharger?

I was trying to figure out how to put a Whipple twin screw SC on. I think if you started with an FI plenum and cut it down, an adapter plate could be made, or an adapter plate could simply be made, though it would be labor intensive.

But yes, that centrifugal compressor would work,and it is a lot less work than a turbo.

You have the advantage of EFI right now, I would have to use either four T bodies under a plenum (turbo or centrifugal), or in the case of the Whipple, one large T body on the inlet to the SC.

Unless you cut your engine cover you won't be able to use a modified stock manifold - the supercharger would simply be too high. Here is how we did it with a Twin Screw

Interesting looking torque rod bracket you have there. Is that factory from a later year or something special?

My '75 GT4 looks lust like it. I suppose sometime between '75 and '79 they started casting the rod bracket into the valve cover?

 

It's factory.....a '78 Euro car

 

That SC has a very long thread here on the site from maybe 6-8 months ago including the step by step development. I was extremely interested for a while but they had dropped it from their website and, when I sent them a message asking for info, they never responded.

That info you posted was from their site back then but there is no reference at all to Ferrari SC kits there any more.

 

Here's the thread: http://www.ferrarichat.com/forum/showthread.php?t=123458&highlight=supercharger

Added this a bit later: Note that the very interesting shop work and general discussion essentially stopped at page 28 with no further input. This, IMHO, was not a good sign, followed by the fact that the SC kit was no longer on their site. I understand it pops up on Ebay occasionally but I don't have a warm feeling about it.

 

Fred if you wait until my high compression 3.5 liter motor is done I will let you try that and see what you think of it. It isn't going to put out what a supercharged motor will but I don't know anyone in the area who will do a suprecharger install or work on it when you are done. At least not anyone you want to do business with.


I have to be honest with you though, if you really want more power you need to get more car.

 

Fred there are a number of ways to increase the hp of the 328

The easiest (but not cheapest) would be a centrifugal blower - no need to make a custom intake manifold, least amount of custom parts/brackets needed. You can start with a modest boost keeping the internals stock, and if you find that the extra 100+ hp is not enough, you can always build up the internals of the motor. Then adding more power is just a pulley change and re-tune away.

If you are interested in what can be done with the 308/328 platform you need to check out this thread:

That is not the route we would go with the fuel injected 328 but it gives you an idea of the power levels and the fact that the stock engine/clutch can handle 310 horsepower at the wheels.

 

Makes it a little difficult to pass California smog.

 

Boost is your friend (and so is search). Here is the graph from my QV when I was running a whipple ax2300 on it.

How so? With 2 catalytic converters in good working condition there should be no problem

 

In California, as soon as the smog tech pops the hood and sees the supercharger, you have a problem. You won't even get to the actual smog measurement portion of the test.

 

Wow. That's ROUGH.

 

Of course the easiest and cheapest way is nitrous. It also has no impact on the engine at all unless it is armed/injecting. Otherwise the engine is completely stock. I admit I still occasionally think about it...700 bucks and presto, instant power - up to an additional 150HP with a simple universal kit (though I would personally not exceed 80-100HP in consideration of the drivetrain) and more than that if you want it. There are also no issues with smog tests since it has no effect on the tailpipe gasses unless it is activated which it would not be for a smog test.

But where does the bottle go? Frankly, that's the main thing that stopped me from pursuing it further when I thought more power was a necessary thing.

Do many of them even know what they'd be looking at with a Ferrari?? Some of the smog places I've gone to with a "normal car" hardly seem to know their asses from their elbows.

 

Fred and I don't live in farm country. Here they are failing them for having Hyperflow cats.

Even a toothless kid with a banjo from Deliverence can spot non stock parts and if you cannot produce proof of compliance for that part it just failed.

BAR is getting tougher every day. If you guys continue to think you will just be able to continue to skate forget it, you're dreaming.

 

i would move.

 

I think many states have the same requirements - the smog equipment must be oem or certified as replacement oem. If it's not, then the car is rejected regardless of how well the new stuff works. I agree it seems silly but it's not going to change. Obviously, if the manufacturer of the equipment - let's say Hyperflow - goes to the expense of having their cats certified, then it's no problem but realistically that's not going to happen.

The same thing is true here in MD when a car is inspected - must have all oem smog gear and it must work. However, if your car is 20 years old it is eligible to be a "historic vehicle" and does not have to be emission's checked at all. Does CA have that provision?

 

It will never happen here.

Thank God

 

Does CA have a point where no sniff check is required? In NY after 25yrs no more emissions, last year was the first for my '83 308QV - always passed anyway cough, cough.

 

Here in PA and when I lived in upstate NY, the requirement was all the oem smog stuff, but there was/is no requirement that the parts be oem or in anyway certified.., ie if it came with a cat it must have a cat, but something like a hyperflow cat was/is perfectly acceptable.

My QV passed with a supercharger with no problem in both NY and PA. I don’t know about Y, but here in PA we also have the 20 year classic plate exempts you rule, so I now have a classic plate and no worries about getting the V12 to pass when it’s done.
