What would make you think you can't supercharge it? I have done quite a few 99's. Give us a call at the shop if you want to chat about it. 913-310-9927

 

hmmm.... you can do a leakdown test to see if your compression is good.

with that said, i didn't even bother when i had sharkwerks install mine at 78000 miles.

 

porschedoc
i heard something about egas and supercharging ?? i am not quite sure what that is...
thanks

No issues that I or Stephen (Kaspar) are aware of. Lord knows we have done enough of them between the 2 of us.

 

If you can afford a new engine with increased risk of blowing it up. Factory FI engines are different for a reason.

 

If your bank account has an extra $12K in it...

 

We have supercharged 996's out there with well over 50k miles on the kits themselves (plus the miles that were originally on the car), they are bulletproof. We run low boost and use the appropriate tuning and injectors to assure this. This is in reference to the EVOMS kit by the way.

 

Sorry, but FI and high compression engines don't mix.......especially those with trouble keeping the oil in (seal problems) as it is. I agree you can sell them, but anybody who thinks there isn't a real risk is delusional.

I stand by the "if you can afford the engine, you can afford the supercharger" stance.

 

It's good to have an opinion

 

ya, opinions and experience don't necessarily correlate

 

It all depends on how high the compression is to start off with.

With turbo engines, the compression ratio is pretty low and the boost from the turbo is relatively high to make up for this. With a typical bolt-on supercharger like the evo or the tpc, the boost from the supercharger isn't very high because the compression is already high (stock). The fact is, as long as you don't boost it so high that it doesn't start knocking, you are perfectly safe.

 

The Ruf kit uses thicker head gaskets to lower the CR, icreased longivity. I think the evo kits will folllow suit.
I think, in the properhands, an evo sc install is bulletproof. I just wish I still lived in KS, I'd have stephen do mine in a second. The local place has done a total of one, and full of problems. In the NE might be better off driving to MD and having TPC do it, they just won Daytona for craps sake, they must know what they're doing.

 

ya they won daytona with a 996 cup car but does that say anything about their kits?

(really not meant to be a knock on them)

 

You just have to talk the wife into letting you drive her expedition for awhile, and put the car on a transport bound for Kansas
