MST Pulley System

Very "Pretty" but the cost is ugly! What else is on the "list" for next winter--I'm hoping Santa will bring my Speedy some new "shoes"  

I'm running a set of those (in a different style) on mine.  I like the setup as it makes it super easy to tighten/loosen/replace a belt.  And it looks kinda cool, too.

It looks neat but doesn't do anything that the stock pulleys don't do. You could spend the $209 on something worthwhile.

Ditto on that ,Yoda.  The guy that built my 1904 engine gave me the option of this installation and showed me one he installed on an engine exactly like mine. It does look really cool, but his opinion was that it was overkill for an engine like mine that rarely gets reved over 4500 rpms. He has this setup on his drag beetle but that thing is a real beast that revs about 9 grand.

Yeah, Al I can see it being a benefit on a street car that drag races, but even then, you pop off the belt at the starting line and put it back on at the end of the track once you're on the return road, otherwise spinning the fan and alternator (or generator) eats power...

Yep you're right again Yoda. I just looked at a photo of the dragster, and it has no cooling tins ,no generator, no nuthin'.

I personally wouldn't use a serpentine belt. I especially wouldn't use one on a fast or high revving engine. The stock setup lets the belt slip which naturally limits the fan acceleration and rpm. The serpentine system doesn't slip nearly as much which can overaccelerate or overspeed the fan causing it to fail. A fan explosion can destroy the engine and damage bodywork.

 

If you've got a stock engine with stock weight flywheel and don't rev beyond 5000, then it would probably be ok.

 

Yes but Al "You'll be soaring high among any VW crowd with this uniquely designed MST system on your motor."

Don't do it, Brother Tom!

 

Resist the siren song of those advertisements in HotVW's!

 

That thing is only good for three things:  (1.) Keeping the belt on a street racer when he's blowing the doors off an unsuspecting Mustang who never expected him to rev (quickly) to 8,500, (2.) Adding a lot of "Bling" for the local cars and coffee crowd and (3.) getting you to spend over 2 Benjamins when you could be spending it, instead, on something worthwhile.  

 

Remember, Brother Tom......"Cigareets, Corn Whiskey, Wild, Wild Women" and Blingy Belt drives..........

 

They'll drive you crazy, they'll drive you insane!

Too bad you can't get a kit like that with a tension pulley.

There is a reason- dry sump setups need very small crank pulleys to clear the sump, and using a conventional style setup means the cooling fan will be under driven, even with a 356 pulley. This assumes you can lay your hands on a conventional-style crank pulley, which was not so easy when I was doing it a few years back. CB's require removing the pulley to install or remove the belt. Scat's were on permanent back order.

I eventually got a serpentine setup from BMD which replicates the stock drive ratio. I've got a welded/balanced fan, so I guess I had to pick my poison... and picked keeping my engine cool.

Most people don't have these consideration, but I did want to point out that there is a reason to use a serpentine setup if it's the only practical way to get the job done.

There is a lid for every pot,  assuming you are ready to pay for it.

Actually I'm not sure whether mine is an MST or a BMD.  The tensioner pull looks different on the MST shown, and I certainly didn't pay $209 for it.

"Product Quality is not an option!"

 

For $209, that is a ringing endorsement

You're all acting like $209 is like shards of the true cross. A decent steel hubbed, CNC aluminum V-belt pulley is close to $100 by itself, without the alternator pulley or the belt.

 

I think $210 is pretty darned fair for the whole set-up.

OK, Stan but considering the stock pulleys basically never need replacing it's still $209 flushed, for most people. As a guy who pulled a running engine and replaced it with something much more complicated, at great expense, for no good reason, I'm just saying.

You sound just like a "Software Guy".  "Hey!  Let's take these twenty lines of code, which work OK but in-elegantly, and replace them with 3,000 lines of code with a bunch of embedded bugs that'll take three people a year or so to sort out!"

Yup, Ed: busted.

 

The weird thing is that this is the only part of my life where I seem to TRY to make it more complicated.

 

Madness, indeed.

 

As to the "stock pulley" point- I'd be willing to bet there's not 2 guys in 20 running a stock crank pulley.

We call that 'refactoring'

Stan! I'm the guy who did the unneeded, expensive engine replacement. Well, one of the guys...

"We call that 'refactoring'"

 

We call that job security. 

I've done several and I'm in the midst of the "mother of all stupidity", so I naturally assumed it was rightly aimed in my direction.

 

Now that I see it wasn't meant for me, I'll go back to garage and resume welding up my fifth (!) exhaust.

 

Carry on.

Exhibit: E

Proof positive that I'm an idiot.

Exhaust either electric solenoid to go straight pipes?

Yes sir. I'm embracing my inner hooligan.

Perfect early morning wake-up call for your neighbors.

OOOOOOOO!!  I want one!!

I approve.

Very cool, as always, Stan!

If you haven't grown up by 50, you don't have to. Welcome to the club!

That would be exhaust cinco, señor. Mucho grande!
