That's cool - the 944S intake is quite a bit different though.

I'm sure it could be done...buy a spare intake manifold and cut off the pipes and weld them to the SC, just like that picture did.

Is that a rotrex supercharger?

EDIT - nevermind, looked at the picture wrong.

Its a shame the whole issue with the higher comp pistons are holding back the potential of the setup. That car would be soo awesome with some higher boost levels.

You could put a reaaaalllyyy thick headgasket on it.

Tim Murphy is running 12psi on a 10:1 928 engine = 500rwhp daily driver.
Jean-Louis was running 6psi non-intercooled on a 10.4:1 928 race car.

With proper engine management, high compression is not an issue. The Asian crowd (cars, not the people) run this type of compression all day long with very high boost levels.

The #1 issue with that setup is the blower itself, not a very efficient supercharger and no IC.

What engine management system is it using? How much timing has been taken out? These are questions that hold back the boost level, not the compression ratio.

For the people who are crying wolf on people not searching first the Search function recently has not worked for allot of people.... Ie all you get is a white screen.

A rotex setup would be alot easier to use, and you could use a IC. The technolog of SC has gone way up, along with easy user freindly engine managment systems, All it takes is some one with some know how and time/money.

As HAcker said those older blowers just arent very efficient and heat up like CRAZY when you turn up the boost. The guys in the toyota crowd had the same kinda thing from TRD on the 3.4 v6. They didnt work to well about 300hp MAX 9-10psi with water injection and a ton of timing pulled. Then the switched to rotex type SC with intercoolers and say LARGE gains mainly beacues there was no need to pull sooo much timing from heat

In your guys' opinions, which would be better oiut of a supercharger; low-end grunt or high-end kick?

A twin-screw like the Huntley/Eaton generally works better in low-range RPM, giving more HP and torque around town. The previous pictures show how easy they are to install, too.

A centrifugal blower like the Rotex acts like a large turbocharger, not doing much until you get into high-mid RPMs and then kicks you in the *** with power. These can more easily be used with intercoolers and could possibly be mounted in place of the A/C compressor on the stock mount.

So which would you rather have?

Tim Murphy's car is putting out 400lb-ft of torque at the rear wheels by 1,700rpm with a centrifugal blower. How much lower do you want the torque to kick in?

V2Rocket

Tim Murphy's car is a low-end torquey V-8 that normally puts out between 200 and 300 lbs at the wheels depending on what model 928...

But I'd like to spin the tires idling in 5th gear.

hacker-pschorr

Tim cannot even do that with his more powerful 17psi car and a 2.73 rear end (stock is 2:20).

I would like to see a way that a person could strap a supercharger on and not have to mess with the engine management too much. I mean make it so a piggyback could be used or have a chip burned to allow a maf be used to sense the boost. I have been very interested in supercharger my 924S, but I don't know really how to get it all started without the right manifold, and supercharger. If someone would make a good manifold to mount a supercharger on such as the one above it would be great.

Here's the detailed info on the S2.

Then 400lbs clearly isn't enough

Of course the '44 is about 1000lbs less than a shark...
