Eric is currently installing a PSE Supercharger onto a customers car.

PSE is from North Highlands, California and specializes in remanufacturing factory superchargers.

It is a ported M45. PSE ports the runners and "S-ports" the supercharger case. They limit their pulley size to a 10%, but claims the same output as a 15% pulley because of the better efficiency.

We don't know exactly what it will produce power wise right now, but will try to put it up on the dyno later on today and get some numbers to everyone.

Here is a picture of it on the car:

 

More choice.

 

Why hasn't anyone tried fitting a completely new supercharger system?
I know M7 had their "twin-screw" supercharger project, but we first heard about that like 2 years ago...........where is anything other than those pics that Peter snapped? Can the twin-screw work? I have heard something about a "whipple" type supercharger, is this the same? What about centrigual type systems?

It seems like there has to be something else out there that all us "S" owners can use to replace our superhcargers for more performance. It seems to me like people should be trying/designing a supercharger system other than the factory one..........just my 2 cents...

 

You're kidding, right? https://www.northamericanmotoring.co...ad.php?t=73771

 

i think he may have been talking about a different type of supercharger rather than just a bigger one. or he could have been living under a rock for the past month or two

 

I read his post are said "WTF, are you kidding ME!?" He must have been living in a hole....I mean, it's not like the M62 Project was noticable or anything....with the 32page thread lol!

Anyway, back on topic....I have to ask the question of ignorance....Why? What is the point of paying more for a "new" ported SC that performs the same as adding a 15% pulley.

WILSON!!!!!!

 

Has anyone applied the Vortec centrifugal type SC to the R53?

 

Ok, so here is the info.

The two dyno plots below are from the PSE car and another car we had around the shop. This is by no means an apples to apples comparison.

The PSE car is an 03 with:
PSE supercharger
Intake
Larger Throttle Body
Unkown Software
Borla Race Exhaust
Alta Intercooler

The test car is an 05 with:
19% pulley
Intake
GIAC
380cc injectors

We recalibrated the dyno for the two different transmissions, but to get the same terminal speed, the 05 car had to tach out higher.

Again this is not a comparison, just something we did because we were curious. We aren't trying to sell anything, just having some fun with the dyno on a Friday afternoon.


Interesting points (difference in mods not withstanding):
-Peak power output of the PSE equipped car was ever so slightly higher then the test car, but the torque curve of the 19% is a lot fatter.
-As expected, the peak intake temps were considerably higher with the 19% pulley (25 degrees at redline.

 

The results don't really "WOW" me...

No offense meant.

I guess I've just been reading so much about the M62 supercharger lately, (I haven't been living under a rock...), that I look at this product, and can't really justify it's need. Not when such a superior option is on the horizon...

Granted, this charger mod might be cheaper than the M62 kit, (one would hope).

I think it's interesting, though!!!

 

Yeah, not that impressive really, but thanks for doing the tests

How much is that mod?

 

I can't see how you don't find that impressive - they've achieved with the modified stock supercharger and a 10% reduction pulley (keep in mind, thats LARGER than the JCW one!) the same power of a 19% pulley, without any of the associated problems of a 19% (heat, slippage, overspinning, etc).

Interesting how they have said to keep to a 10% reduction in size. The increase in flow (and decrease in temps) to me means that its still not running in that effecient range a 15% usually does...

 

What will happen when you slap on 17% or even 15% on the PSE SC?

Will they make it inefficient?

 

From my half asleep thinking, slapping a 15% on would give it a nice kick in the power and torque range - also don't forget that the tuning can have a fair bit to do with this!

I'm thinking that they specify a 10% reduction over stock to keep it 100% reliable - like how the "JCW" veined chargers are. Another thing to keep in mind is the coating on the blades...

 

not that i know of but that would be really interesting to see...

 

How did the IATs compare at 4,000 rpm?

 

Weird! I was just looking at these today(Paxton actually), and picturing how it would have to be setup.

 

I think there's room for exploration here

 

you have to keep in mind that the car with the PSE supercharger had alot more mods then the one with the 19% pulley

 

If we are going to discuss it, maybe we should start another thread.

 

I think it would be quite a project. I myself would convert over completely to an MC intake setup before i ever attempted to do a centrifugal SC on the MINI. The throttlebody is upstream of the SC on the MCS, unlike something like a G60 Corrado, where its an easy task to put on a centifugal SC.

 

The Vortech site states that their units allow for upstream throttle or draw through use. Would probably have to use the MC water pump assembly and related parts, or a universal electric type.

 

This is a little off topic since this thread is about SC's but I know for a fact and have seen in action that George w/ Mini-Madness has strapped a Turbo on a MCS in place of the SC and it kisks butt! They were in the Euro Tuner Challange last weekend and placed 4th out of 12 behind (1st Elise, 2nd Audi, 3rd Audi). It was dyno'd as well and hit 335hp
Just my 2 cents

There are quite few members who are running turbo only setup..
they are very well known for the ultimate way to the high HPs..
If you wanna go big, lose the SC..

 

Ahhh, but if you lose the supercharger, you lose its' SOUL!!!

Superchargers 4EVER! WOOO HOOO!
