Thanks!

Marty you will need heavier front springs with all that extra weight!

Could you have Jeff call me about transmissions one of these days. Time to start thinking about what direction to go. I have received some good input on them. Need his to make a final decision.

You would be surprised how little it will add. The problem is how much weight it will take out of my wallet!

Shall do!

[Blk Mamba]

What about all the room it eats up?

[Blown3.8]

I have a buddy thats gonna throw one of those on his 3.8 t bird. When he gets it done I'll try to remember to post some pics up over here. No belt slip there thats FO SHO.

[MrBluGruv]

I didn't quite understand the importance of this until I looked at it a little more: am I right in understanding that's a direct-drive centrifugal blower?

Not an issue.

That. Is. Awesome.

That's why i want your credit card number! C'mon you know you always wanted to own some awesomeness!!!!

[MrBluGruv]

LMFAO, that's never worked for me before boss, and I don't even have the kind of toys you do either. Ask me again when I'm not a poor college student. :P

[Joe Walsh]

You'll need a custom radiator with a big hole in the center!

That is a neat looking blower set-up.
Reminds me of the really 'old school' Bentley Blower...

You won't be throwin' any belts with that contraption...now will ya??:shake:

The whole car just flips over......

[Joe Walsh]

Why the double gear boxes?

You've got to lose 50 HP through all those couplings and the second gearbox.

I have not handled one (yet), but I am told that these things are the ****nit powerwise. Even teh folks at Procharger recommend them (although they do not make them).

BE CAREFUL!!:eek:

[RR|Suki]

it is rather irrelevant how much HP is lost in the gear box if the net gain is massive.

[Egon Spengler]

*cough* That'swhatshesaid *cough*

[Joe Walsh]

The HP gain would not be as "massive" as a common belt driven blower...just more reliable (no thrown belts)....maybe.
I still want to know why they run it through 2 gearboxes and umpteen couplings.
It looks too much like a "Rube Goldberg" to me.
If I were going to go through the trouble of making that thing work on a Marauder, I'd save a lot of time and a TON of money and do a well engineered intercooled turbo system....
The most efficient forced induction method...no belts, no gears, no couplings, no boost tied-to-engine rpm....Just crazy torque and horsepower.

[Blk Mamba]

I would think the gear box would be to change ratio, much the same as changing pulley size, the couplings to prevent excessive wear from torque.

[Joe Walsh]

That makes sense.
So now they add a second gearbox, a second set of brackets and 2 more couplings instead of; 2 pulleys and a belt....:rolleyes:

I still say TURBO!

[SILVERSURFER03]

hey you could always lose the trans and go direct drive no loss of hp there hahaha... that set up looks AWSOME

[martyo]

Joe:

Spomsor me on a turbo set up and I will test your theory.

Meanwhile, trust me when I tell you that these set ups make a ton of power and are well-respected.

[massacre]

Reminds me of the old Mooneyes Dragster, which I had the good fortune to see when I went to Moon in Santa Fe Springs a year or two ago.

I believe they may have been called "Potvin" blower drives?

http://img232.imageshack.us/img232/6455/potvin20blower20drive.jpg (http://img232.imageshack.us/i/potvin20blower20drive.jpg/)

A lot of the 60s drag cars used these.....

So I guess it's been revised to a centrifigal blower instead of the positive-displacement blower.

40-year-old technology FTW!

ummmm if you wanna try to drive an F2 etc. with serpentine belt you go right ahead :rolleyes:

PS if you really think turbos don't depend on engine RPM. . . I don't even know what to say

I don't know......... When a lawyer says "trust me" :D

I'm selfish....Me first!

OK...I believe you.


Here is a question...theory that I have:

You are shredding/throwing belts way too much...right?
Centrifugal blowers do NOT have a clutched input pulley like our OEM alternator...correct?
Same problem as our 'chirping belt' (non-clutched) alternators:

You have the engine, crank pulley, S/C drivebelt, S/C gearbox input pulley and S/C gearbox spinning at @ 7,000 rpm,
plus a S/C impeller spinning at...what 30,000 rpm?
You hit a gear and your engine and crank pulley suddenly slow to @ 4,500 rpm.
The S/C gearbox input pulley, gearbox and impeller are still at full speed -> @ 7,000 rpm .
The only thing between the two rotating masses at mismatched speeds.....is the belt.
Now the belt is suddenly forced to slow down the S/C gearbox input pulley, gearbox and impeller.

Is my scenario correct...or am I missing something on how a centrifugal blower works?...:dunno:

[Joe Walsh]

PS if you really think turbos don't depend on engine RPM. . . I don't even know what to say

I'm talking about the linear boost vs. rpm curve of a centrifugal S/C.

Plus, have you ever punched a turbo at highway speeds in 5th gear?
Under that load the boost comes on at a lot lower rpm than when you punch it coming out of the hole.

[babbage]

Gearvendors over/underdrive systems use about 1 (one) HP per 300.

This is the cost of the gears. Not sure if the Procharger setup is as efficient.

Using a higher gear is the common way to check for boost issue because sure with more load you'll read more boost, but that has nothing to do with power, since power is still work over time. . . That's why you can go to 5th hit the gas and see the boost quickly, check leaks, bypass etc. cuz you still aren't going anywhere until the RPMs come up :rolleyes: again HP is work over time. So any way you look at it you need the RPMs

[rayjay]

Interesting, subscribing to learn.

[Joe Walsh]

I still say twin TURBO Big Block FORD!

There....Fixed my own post!

Yeah...but with a turbo you still get that awesome swell of torque at lower rpms under load!...:banana2:

First off, I am no expert -- I have people more knowledgeable than me to help me with some of this.

We don't throw belts when the car shifts. we always throw them when the car is unloaded aftrer a burn out (although we did toss when on a launch at the fat Car Shoot Out..

I am looking for solutions. The gear driven approach is well respected and so are turbos.

I am weighing out both. In the meantime, I need a financial backer! :P

[rayjay]

I just want to know how the hell is that gonna fit on the front of the engine and still have room for everything else that goes up there? Unless you are going to be dropping off a bunch of stuff so its not really a street car any longer. Someone please enlighten me. Also, doesn't the tranny take some major "hit" so to speak when you drop the hammer? Perhaps this setup would work best with a manual that can burn off some clutch material.

The front end of my car is very different than other cars so that gives me clearance Clarence.

I don't agree with you that the trans will take any worse hit. My trans is rated at 2,000 hp.
