supercharger
 

I have found this on ebay!

anyone tired it? is it good?

how this can increase engine's psi and be called supercharger? It looks like just an air intake mod, not even close to turbo :)

The general consensus on this seems to be that it can't work in theory or in practice.

:cheers:

I am of average intelligence and not an expert, however I am smart enough to realize that there really isn't all that much to do for a porsche. The engine is highly tuned, the aerodynamics have been optimized and the suspension is built right. Maybe there is a few MINOR things you can do to help the car, but if you want more HP, buy a 911 or Cayman. Just my opinion and I'm usually wrong so you have that going for you.

Actually, I think you are very dead-on here. However, with several qualifiers I would add.

Yes, you can do tons of things to the Box to generate increased performance. However, the serious power comes with:

-A very high price tag that will certainly turn off many would-be racers.

-A low probability that these costs will be recoverable from later buyers of said car

-A likely decrease in streetability of the Box

-An increase in maint. and repair costs

-An increase in tire expense

-An increase in speeding tickets and later on, insurance rates.

Given all these caveats, there plenty of folks who want your money!

Let the good times roll!

Rail you now impress me. All the gizmos to enhance the performance of a Box are very expensive with minimal returns if any at all. The item in question the supercharger, there is a company with a website http://imagineauto.com/ that has a supercharger for the Boxster. A new product. I would say it is going to be from $5,000 to $10,000 range.
In your next post I'll hear from you are driving a fixed wing airplane, wow. :)

Pilot, now this is what I called a supercharger :) I want one though if it doesn't void the car warranty.

FYI: I got quoted $8000 for a supercharger for the S version from imagineauto. It might go a little less for the base boxster as it requires less kit as what I was told.

I like how its SO reputable that it doesn't even have a brand name... not even a fake one... at least take the time to come up with a creative name for it...

looks like a part from a leaf blower that he just installed the filter on... i think it would be better to just have the K&N airfilter minus that weird fan.... it probably constricts airflow more than anything else...

I wunder how many of those $10 leaf blower fans that guy has sold.... a nice profit in my opinion.. ;)

After talking to a rep from imagineauto (www.imagineauto.com), I feel close to being persuaded in ordering one despite voiding the engine warranty...There is a lot of 'higher end' Porsches but not Boxster with supercharger.

Before I decide to burn $8000 in my pocket, anybody has any thought about the supercharger? Any opinions are welcome.

Hi,

My thought - Save your $8000 - don't do it - you won't be making the Car better...

Happy Motoring!...Jim'99

Of course, as always, just my humble $0.02 :)

Just a couple things I’d like to mention, and I’m no tech guy as you will see:

Superchargers sound good and it seems to me we all crave more hp/tq. This one’s a centrifugal s/c which means you will find the max power you are looking for at the upper end of the rpm band. Is that where you want to go to get it? Nothing wrong with that, mind you. I’ve got a similar non-intercooled s/c (7 lbs boost) on my daily driver, a ’99 Miata. It zips right along but the motor has to be cooking up around 4500-5000 before the difference really begins to be seen. I don’t know of any centrifugals that give you a lot of real low end pull, and typically that’s where most folks want the extra muscle. You may want to ask the proprietor for a dyno graph overlay depicting the hp and tq over the rpm band on the Box 3.2 litre with and without their s/c so you can see where/when the power is delivered and whether or not that meets your driving style.

Another thing that comes to my untrained eye is there is no mention of the oil/ lubrication system other than the s/c comes with “oil for the blower”. The charger will need continuous lubrication. That means periodically you will have to go in and unscrew something and check and add oil to whatever reservoir it has as opposed to having a constant feed/return from the engine’s oil supply like Vortec uses. Some folks say those s/c’s with the permanent oil line last longer.

Presumably, if the s/c serpentine belt breaks, you can limp on home as long as you don’t get the motor up in the area where the GIAC software changes things. That’s how it is with my s/c. I’m kind of a “belt and suspenders” guy so that would be important to me.

Not looking to dis anyone’s product here and certainly the rest of the ladies and gents on this board are free to disagree and hopefully correct me if I’ve stated something wrong.

Having said, the little boy in me keeps saying, "Go get it and come back and tell us how really really great it is, so I can get one too!"

Zib :cheers:

My 2000 S is at Imagine Auto right now having the S/C installed! I have dealt with Imagine Auto for a few years and find them to be a class A operation. Stephen is very well respected in the 996 and 930 group (see 6speedonline). Imagine also had one of the 996TT in the "High Roller Shootout" featured in Excellence last year.

For day to day driving the S/C does not factor in till you reach a higher RPM range. Stephen has assured me that this is safe HP and we will be running safe boost (4-6lbs). Please go to 6speedonline and check his reputation out I promise it is impeccable. I want to go fast but keep my 3.2 in one piece. I should see it in a few weeks and let you all know how scary fast it is. My first night I want to find a stock 996TT and see how I fair.


:cheers:

Your bravery will not be forgotten :D

JP in St Louis, please post pictures and other info when you can (even while it's still in installation). I'd love to see how it fits!

I have seen one installed on the 2.5 and the only way to see it is by being looking from under the car on the passenger side. A mirror alwo works if you put it under the car.
:cheers:

If it were me, I would sell the 2.5 and go with an S.

Simply a better car, IMHO.

:cheers:

Bruce: Thats what I think also thats why I bought the 3.2. But damm I still want more. The location is the same on all the cars. I can tell you that the 2.5 with the S/C can run down a S (3.2) with ease.

I have my eye on my next toy a 930 or 964 turbo 3.6. But I cant swing that for about a year or two.

:cheers:

Are you going to dyno your car after the s/c installation? Are there any additional modifications needed like a clutch upgrade or strengthening the internals?

Check out the following site. My dream car is to find a washed out 968 Coupe and drop in a blown LS2 engine.

Wow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!

Brucelee, 968 with LS2 engine? Let's call it "Porschvette" :)

Whatever we call it, we can also call it FAST!!!!!!!!!!!!!!!!!!!!

:cheers:

Just want to bump this up. Is the installation now completed? Would appreciate some pictures! :dance:

Supercharger status
 

JP,
Please let us know how the Supercharger performs on your "S". I also have a 2000S so I'm VERY interested!
Thanks,
Rich in CT

Not finished yet as all the upper air intake had to be fabed. I will keep you all in the know. Since this is the first that Imagine has done I will let them keep it as long as they want to make sure it is perfect.

My heart stopped pounding for a sec when I saw this thread :D
Do they have any time estimate as when they will finish the installation?

SOON VERY VERY SOON. It will be done this next month or two.

We have to make a custom set of headers for the Boxster S, as the supercharger sits right where the front O2 is mounted, so that is going to be the most time consuming. On the 2.5L, this is not the case, as the O2 sensor is farther back, so it is a direct bolt on. We just got the rolomolded plastic pipes in this week for the intake tubes, everything fit with the exception of 1 pipe, which we need to make a small modification to, so that got sent back, and should be done here shortly. On the 2.5L cars, we pick up almost 100 horsepower to the wheels runnign 4lbs of boost. This puts the car at about 240RWHP. We are hoping to get this done in the next month or two. The S will also have the same extensive programing through GIAC to make sure it is run at optimal conditions throughout the entire rpm range. All tuning is done on our in-house Mustang AWD dyno.

Also just a quick response as i was quickly glancing through the posts about the self contained oiling system.

We went with the procharger blower which has a self contained oiling system. The oil will need to be changed every couple of thousand miles (I can't remember what the number is, IIRC it is around 6k miles). Problem with using a vortec blower, is that
1: It takes oil away from the engine
2. That oil coming from the engine is very hot, and actually causes the supercharger to run hotter. This we did not want.

We are working directly with Procharger here in town, who come out on a regular basis, so we are confident that this was the smartest choice for this application. With that being said, we do utilize the vortec on the 996 supercharger kits, which was designed by Evo Motorsports, and there have been no issues with that kit.
