What if "SC" stood for "Super Charged"?

[kamikazepilot]

Well,

This peaks my interest, gonna find out what the price looks like and maybe, just maybe this will be in my SC....

I wish we had a Warren, John Walker, or Roland who could give us the unvarnished truth about these systems, as well as the TPC Eaton supercharger. If someone can convince me that it won't dramatically shorten my engine life (and that I won't need to add a Turbo tail), I'm ready to jump.

I've been keeping track of our local PCA's "track whore" supercharged SC.
This car gets beaten hard and regular. The PO and the CO both use the car for pure fun as well as racing. They both have let others drive it and will give anyone who asks a thrill ride.
The PO, who had the whipplecharger installed, and the CO have been diligent in repairs and upgrades. The engine has been supercharged for a few years now. I believe all the bugs are out and the motor hasn't been cracked open for quite some time. The CO has scheduled 12 or more driving events this summer all over the US. I can keep you posted.
I tried to post some pix but photopoint is no longer letting me do it (for free). I'll try the new BBS method when I can get to it.

Jack, as you know the big question mark with your application is the compression ratio. The SC lends itself a bit more for the upgrade with its more modest ratio. I'd be a little shy about it myself.
Think a 3.6tt will fit back there?

If SC stood for supercharged, there would be a lot fewer posts on this board.

I never got an answer on this when originally posted, but my owners manual specifically refers to emptying the supercharger oil resovior. What's up with that? I didn't think there were any supercharged SC's.

What are you trying to say?

My SC ISN'T supercharged??????


Seriously, I have told chicks that before.
Then they say wow...it's got a supercharger in it huh?
And I say....um, no.
That really gets the Blondes a thinkin'.

True. But if all SCs were supercharged, I think we'd also have head studs going off like popcorn.

I don't post very much,but I follow this board allmost everyday.I installed the Whipple kit about five months ago in my 86 3.2.The Installation was tedious and time consuming mostly do to poor instructions.The results are very impressive,this car is fast.So far the car has had no problems and seems as reliable as an 86 can be.Some day I'll get a camera and post pictures of the car.I don't track or race the car,so I don't know how it would hold up under those conditions,but on the street(and my assumption is that95% of driving done by this bbs members is on the street),it's a blast.I'n my opinion everything about a 911 is performance,sitting still it radiates off the car.The power available in the older cars does not live up to this.I get a kick out of the guys who think the only meaning of performance is a skidpad.I don't think you can find a car that was built in the last 30 years that dosen't have 0-60 times(Porsche even posts these in their owners manual).Power is a key element in performance,to deny that is making excuses.

I've been looking into these kits for the last several months. I'm very interrested in the TPC set-up. They will have a kit ready for the 3.2 later this summer which should be readily adaptable to the SC. While I can't find hard data the concensus amoung those that have had superchargers installed is that they have not experienced a loss in reliability.

By the time winter gets here I need to decide between new P&Cs & Cam set up or supercharger. Anymore input would be greatly appreciated. It's got to be time for anothr update from natchamp on the supercharged beast he's working on.

Hello

Well I know I guy who startet with a Paxton Blower ( Well that part was made for his Avanti, but he shouveld a Hemi in it, you guys know when you sit in the garage and have some beers to much the fanatsy goes a bit wild ) and managed to get a B&M forced induction on his 3,0 turbo. Money wasnīt the object and he liked to wrench on the impossible. B&M Forced Induction also contained a full progamable FI ( Fuel Injection ). Well he made some 380 HP and low 12 runs but the roots blower needed something like a 5000 km rebuild intervall. Fuel Milage was better. And the smoth power gave fine oversteer action. Low spot was that after hiting 5000/min the power breaked in. But all big blocks do this. ( And the Ruf 5 speed helped on that )
This guy owens a company who does development work for heavy industries ( Power plants ) so he used his own sources.

Supercharging does work if the engine layout is made for it. An add on system will work in the staates but not for the european driver who can drive WOT untill the fueltank winks for a pause. ( or the engine spits out the parts )

To give you a picture just ask any US Car Tuner or Hot Rodder what yoou need to give a 200 HP V8 a 50% energie shoot. Say its a four bolt main. They tell you its a bolt on ? And then ask them you will take the car on the race track and on extensive full load action on german highways ?

Now the picture shifts as they just count up you need larger cooling bigger EFI, beefier trany with sport clutch or special converter, 14 bolt rear axle and many other tricky stuff.

Now, you donīt need all that becourse most Porsche parts will not break ( except the pistons ) only wear faster. The truth is: no free lunch.......

Most people will get as much power as possible for the money and a mild blow will not pay back as those systems eat power to drive them and add wight to move.

Today there are more efficient units around, Rotarys or the G 60īs also the new Roots generation from Eaton seem to be good choices. Paxton like blower where used on 928 and new BMW. And those engines survive WOT in germany.

Kolbermoor made supercharged 964 and 993 in germany and those guys are not around anymore.

So it is very simple; If you gona use it the american way ( Some sprint events and many cruising ) you will be satisfied and it suits your needs. And if the engine blows up or wears down in short time, the trany looses gets loud and leaks, the CV makes clunking noises,.......you move the big buisines wheel by buying many parts and spending much on labour. Very good for the economic.

BTW supercharging is very well known to the Porsches. F:Porsche used to built his own beetle with a supercharged engine his father used that for the SSK and the Auto Unions. Donīt think they didnīt had used that if it would have payed back.

SC is short from SiC

( SC = Super Construction, SiC Super intelligent Construction )

I always enjoy your posts.

Thanks for the info, I know there is no FREE LUNCH, but one can not make horse power without some losses in the reliability department.

I assume from your post that you agree with this.

Anyway, here is a pick to peak your interest, this is INSANE!

Twin superchargers?

I see the twin screws but no intercooler.
More info!!!

[TWIN911]

Missed the Pelican crowd on Sunday, maybe next year. In any case, for Rarly8, the twin supercharged car was done by P.B.R. Restorations in Crockett CA, 510 787 2200. They say that the supercharger they use doesn't induce as much heat into the system as others, therefore no intercooler. This was a one off, the car is a 77 with a slope conversion and the engine is a 3.4. Get this, the owner doesn't even track it! TWIN911

He wouldn't necessarily need intercoolers if he's running low boost. Even 4-6 psi can provide 50-75 easy HP and gobs of torque. But I would like to repeat what's been said in the previous messages; unless you're starting with 400 cubic inches, there is no free lunch when it comes to increasing horsepower, especially adding 50 at a time. Do expect added stress and wear to your small displacement engine whenever you add to its power output.

Hello

Some man dream to build there own car. If I would have build on a Porsche would come to live. So many people feel like the Porsche is a piece of there mind. But some do think they could have made some or many things better. So they have to try it as they are not conform with the Porsche phylosophy in all ways. How needs a good reliability, low emmisions and polllution friendlyness if it costs power ?

So suit the car to your needs like every other tool humans use.

If you are becoming your own engenieer it will all be up on you. You will learn a lot and every misstace costs very much.

Well I made so much things on Porsches and other cars and payed so much that Iīm tired of that and just enjoy driving without any screwing or thinkink wher the damn thing will brake. Just threw in your thoothbrush and drive to where the car will go. Normaly he wil like to play on those itzy bitzy little roads wher the engine has enough power even if its only 50 HP. Porsches donīt like bullevard racing. So I spend my time siting on the computer listening to "penguin cafe" and answer for me boring tuning themes.

Back to TOP:

It is well known to industrie that blowers are more inefficient that turbos. But the normal Guy can make blowers much cheaper the turbocharging. The principles are very close but the mechanical drag from the blower is much higher while the exhaustgases are nearly for free.

If you doubt that, recall that Callaway made solid 850 HP with twin turbos on 350īs in Corvette and Camaros. A comperable supercharged engine had 700-750 HP. The Callaway Camaro looked stock and had the carbs under the front lights in the high pressure zone, no intercoolers. The charger had the blowerpack looking out the hood lowering CD and topspeed.

So even on domestics the blowers where only used by people who couldnīt develop a better system or just liked the macho look and fat noise.

If you want more power then you have to find out what kind of power and go for it. If you add on the blower you might get a 100 HP gain for several secounds usable, enogh to get faster to the next red light or speed trap. But it still will not be enough to beat amodern supercar or a good Hot Rod.

The best way is to remove the engine and install big fat V8 with an blower so that the intake sits obouve the roof ( shaker hood ). A small block can be pumped up to 460 CI and give some 800 HP to the trany.
A good trany is the Oldsmobile Tornado unit. Reshaping the rear for some fat Mickey Thomsons and donīt forget the Bull bars and indipendend brakes for steering if the front lifts up.

For the case you meet a similar made Domestic or a Race car just add two sidewinders as startbooster.

America seems to be digital.
There is only 1 and 0
And everyone will be 1,
but the 0 is the more important number.

My advise is simply save the money for more usefull things. Ever had been in a race car shool ? On Driver Education ? In Paris ? France not Texas. Live is so short while allways stay in the fast forward mode ?

Tell me a Sissy but I donīt need a car to show Iīm the best. ( EH ? who said I do it here by showing off ? )


Rantmodeoff.
