Marco did put a bigger pulley on it and it was slipping and not making enough boost.

OMG I love that car, I wish I was there for the build, I want more pics more info on everything

DAMNIT! If that man is a Rennlister, tell him to pipe up and post more pics, PLEASE! If he isn't, could John D. just give him a membership just for having the most rediculous 944 on here?

1) Vortech Blower (what trim is it and how much boost is it seeing?)
2) Direct-Port N2O sprayers... how much is he spraying?
3) AccuSump hidden under the RF fender, nice touch.
...and this list goes on!

Could we possibly see more pics? I'd ask for a PM but I think I speak for everyone here when I say "DAAAMN!"

Keep it! Why would you ever want to sell that thing? If the pulley is spinning on power, why not see if the belt can't be tightened anymore? Blower pulleys generally run pretty tight.

I'll drive out and takes pics for you guys if you pay for my gas!!! :roflamo:

I'LL put down some money, but it better be sweet pics and every inch most be taken and you need to get every peace of info you can get

The problem was setting the proper tension of the drive belt.* The newer flat ribbed belts require much higher tension then the old V belts to work properly.* There is a gauge called a belt tension gauge that you should buy to properly set the belt tension, but they are expensive and sell for around $100.* Belt problems seemed to always plague the supercharger because people just would not spend the $100 for the proper tools and it seems that the dealers that are supposed to have them many times don't.* If the belt is to loose it will slip, wear out faster, and may jump off the pulleys.* If it is to tight then it put excessive load on the bearings in the supercharger nose drive, idler pulleys, and alternator.* There is a very fine line between to tight and to loose, neither is a good thing.

Do you know how may lbs of boost he is getting? and what his compresion is? My SC set up is no where near as complex looking as that set up ? There is some seriouse plumming going on there. He needs to plow on and finish.

i think he is supposed to be getting 11psi and is only getting 8? not sure.. i'll have to ask him.

Lance, you should know by now, Mark has every imaginable tool for these cars in his shop! Considering he's in the Pizza biz, I'm always amazed he has the time to work on the car. Oh, if nobody has mentioned it yet, he has a 3.3L blown motor being put together for this car! That's on top of the 2.8L he already bought..... that's why the "total $$" noted may be a little conservative.

oh friggin hell,i just **** myself!hahahahaha dang supercharged and nitrous injected!THAT IS ONE SEXY N/A ENGINE BAY!

Mine is an 88 with a stock motor. the stage I kit is 5 psi and my Stage II is 8psi with the addition of an intercooler, bigger injectors, 45 psi fuel and a MAF. Tim at SFR said with stock compresion 10 psi would be pushing the limits since the stock motor already has high compression. my 8 psi pully is pritty small so I can imagine a smaller one may start to slip.

How much power/torque are you making, tt??

Dyno results from a stage 2 supercharger...

Actually I think he is using a Stage 4 designed as a 944 turbo replacement..... ( I am not sure if SFR is offereing these anymore).... so a lot more power to be had...

And as far as I can recall he is still using a turbo bottom end.

It looks so yummy.

I say park it for a while and hit it again with fresh ambition and patience. That's what I do when I get into a rut...
