Supercharger baby!

[EMGEBE]

been lookin through ebay.

Found this...
Toyota Supercharger

Its alot smaller than the moss motors one, but a heck of alot cheaper.
Whatchu guys recon?
A possibility?

The trick is going to be getting it mated to a manifold and carb for your engine. The money you save on this one, will be spent there. Believe me Moss spent alot of R&D $$$'s on making sure theirs was bolt on and "WOW"!!!

I don't think the cast iron tractor engine would last long with a supercharger but we would all love to see the results!

Go ahead!

It could work. It would be alot of work, but it's possible.

When you strip it down to the basics, all a supercharger really does is increasse volumetric efficiency so just about any naturally aspirated car can benefit from a supercharger. Engine life depends more on how many psi you cram into your engine at what RPM which is determined by supercharger pulley size as well as compression ratio. If you think it might blow your engine, get a bigger pulley for the supercharger which will make it turn slower and produce less pressure, etc. I certainly intend to use some sort of turbo/supercharger system on my MG (when I get around to affording it!) Going with a used transplant unit is a good way to go as long as you feel comfortable fabbing something up (or having it fabbed). Good luck and we certainly will all be waiting to hear the results!

It does more then that. It increases internal presures and stresses. The engine just isn't designed for that. The rings aren't designed for the at, the rods arn't designed for that. If you have more power, you will use it. The moss chart shows a peak at higher RPM band. You will use it if it is there. Nothing in the engine was designed for it.Even your oil system is not designed for it.

OK, let me refine my point:

If you hooked up the supercharger and set it to produce zero psi, you aren't going to damage your engine.

If you hooked up the supercharger and set it to produce .5 psi, you aren't going to damage your engine.

If you hooked up the supercharger and set it to produce 10 psi, you are probably going to blow up a whole lotta stuff!!

Somewhere in there exists a happy medium where power, fuel economy, volumetric efficiency (VE), etc are all increased because the s.c. eliminates the effects of things like barometric pressures, gravity (which also effects things like air and gas charges and the way they move) and especially the viscosity of the atmosphere which all make a naturally aspirated car run somewhere well below 100% VE. I think most cars are about 75%-85% volumetrically efficient.

I'll try again to put it in simple terms for an example. If your car has 1000cc engine, naturally aspirated (NA) it will use about 750-850cc of combustion space where as charged it will use the full 1000cc or even more (the "even more" is where people get into trouble). On a NA car as the engine moves through the power cycle it creates a vacuum in the combustion chamber. All that induces the charge into the cylinder is this barometric low spot, however, it has to "pull" the air/fuel mixture in to fill the void. Under normal conditions it can't do this fast enough which is why you only get 75%-85% sucked in there before the valve closes and the piston starts the compression stroke. Adding a turbo/supercharger gives the ability to force the air in faster and fill the full 100% of the cylinder during the intake. With smaller pullies and therefore higher psi you can even increase VE up to 110%-120%.

NOW, all that said, it is up to YOU to decide how you want to use your car, how sturdy the internals are to begin with and how you're going to drive it. Those factors are all independent of the benefits of charging.

Well, no kidding, that's why the moss SC has so little boost. And people have still had trouble with it.

This ebay Supercharger gem sounds like a ton of work. In addition to fabricating an intake manifold, you'd have to find an appropriate carb to feed fuel to it. The stock HS4's won't cut it. IMHO, just freshen up the motor you've got. Slap on a few basic bolt-ons(cam, exhaust, K&N filters, maybe a crossflow head, HS6 carbs, etc.) and be happy. These cars aren't designed to be dragsters. If money is enough of a consideration that you'd rather skimp on the blower and buy used piece off ebay rather than pay for the MOSS unit designed specifically for your car, chances are you'll take short cuts when it comes to your engine internals themselves. This can be a disastrous combination. Be careful!

For the record, the B-series engine was never used in farm equipment. There was a Triumph engine that had agricultural roots, not sure which one though.

I would have no problem putting a Moss SC unit on my B and may very well do so when I rebuild it. The majority of people who are having SC problems are the ones who put them on old high-mileage engines. Anyone having problems on a new engine is probably suffering a case of over-engineering.

Just my 2.44 cents USD. /ubbthreads/images/graemlins/smile.gif

I've thought about the supercharger, and mating it with a Ford T-5 trans, just to make the car a bit more aggressively driveable. The total cost of the two together is over 5K. So, I probably won't do it, but the transmission by itself is a strong possibility.

For the record the 4 cyl motor used in Triumph TR2-TR4 (and derived from the Standard Vanguard motor) was sold TO Massey Furguson to be used in their tractors.

The motor came first, the tractor later. Supossedly if you can find a Massey Ferguson dealer they still carry things like water pumps that will fit on TR motors.

Ah, that must be the one I was thinking of. Thanks for clearing that up! /ubbthreads/images/graemlins/smile.gif

Interesting about the modern parts dealers.
