more supercharger talk

[truckinwagen]

realistically I would have to relocate the radiator anyway, so yes, seeing as the motor mount can be replaced with a bolt and hockey puck with a hole cut in the middle.

[macka]

jeebus, whats with all the hockey pucking? Those aren't made for supporting anything structural. I'd use it a a mold to make a proper poly bushing for that.

[truckinwagen]

well, maybe a hockey puck shaped piece of rubber that is thinner than the stock mount.

[truckinwagen]

well, this whole project has just been put on the fast track.

my GTI's clutch just failed, so I need to finish this quickly and shove it in the GTI(I really dont want to buy and install two clutched back to back)

a few things will be put off until later, like the head porting(I have a spare head to work on while the car is running) and the girdle.

I have a few new better ideas about how to do the girdle properly, and don't want to rush it, and again I have a spare block to do the girdle work on while the car is running, so no real loss there, I just wont run the motor too hard until I get it in.

I think I could have the car ready to test fire with one more good days work, I have all the parts, I just need to do assembly.

thats not looking so great, might have to put it in a fox or something, the alternator barely fits on an ac car,

That monster categorically would not fit set up like that in a Fox. There is enough space on that side of the engine for either the injection pump or an alternator, not both. They occupy the same space to clear the side-mounted radiator, which has very little space to move about in any direction to add to that clearance.

That G60 is too big and bulky. BBM's Lysholm is much more compact and has a higher efficiency rating.  I ran into the same pully problem with my caddy, but I am using the Lysholm.  I am just glad it is more compact, I had a few more options with mounting.

[truckinwagen]

the G60 will fit!

it might take some massaging, but it will fit!

[Smokey Eddy]

Certainly a VNT with a proper vane control will come close to the performance of a supercharged or twin-charged motor without anywhere near the cost, complexity or efficiency loss.  At the same time I'd love to see someone do a twin-charge and would also love to see the burnout videos.   

Who doesn't want to see burnout videos
I am a strong believer in the VNT design. A good vnt is alllmost as quick as a supercharger whilst, like andrew said, requiring little to no power loss. Were i able to afford one i would have one on my car.

[tindias]

That is all true, but this is something different. The BBM SC can pump out 22 psi in no time at all, just imagin the fun!

[truckinwagen]

the supercharged(an eventually twincharged) motor idea really is to do something different and to prove it can be done.

as for the usage of the G60, it was cheap(and they still are compared to lots of the alternatives) and to prove that they are not a grenade sitting under the hood, but can be used for reliable power.

I just received my new alternator, and hopefully will be moving along with this pretty quick.

just imagine how much power it takes to pump out 22psi? LOTS! a turbo makin 22 psi will take right about 9 horsepower to build the boost.

[tindias]

The intake will be finsihed soon on my caddy.  It should be finished in about 2 weeks, I hope.  I have a 02 TDI so the caddy will just be a fun car.  I dont even think I will notice any HP loss with completely unrestricted exhaust, but we will see.

A Lysholm will not use any more than 9 hp to make 22psi.

I am pretty confident that the motor will make lots of power regardless of the parasitic loss from the supercharger.

i call extreme bull***... theres no way you can compress 22 psi of air with a roots supercharger powered by 9 hp. roots/twin scroll, what ever, it takes more than 9 hp. a eaton M90 takes almost 40 horsepower to make 15 pounds of boost...

lysholm superchargers do not work with voodoo and black magic.. the laws of physics still apply to them too.
