Of course! Starting with replacing your headgaskets.
They will fail at about 11 psi (the 928 ones do).
I also think the stock fuel pump will prove too small at about 11-12 psi of boost.
These are reasons why our kit is designed for 6 psi .

I'm still wondering who copied this unique design. I've seen several different supercharger set-ups for the 968, and all of them are different in many ways.

Hi Carl,
Thanks for the reply on the fuel pressure question. Just want to clarify that your kit is simply bolt-on and I dont have to 'tune' the FMU on the dyno with wideband o2?
Im a bit worried with quality of our fuel here, at most its the 91 octane in california, do you have the air-fuel graph done during your dyno testing? Is it ok to see the results?
Any experience or comments if the tiptronic tranny can handle the stage 1 and 2 applications? thanks!

Is there any one who can point me in the right direction as to why I have 60 PSI at the fuel rail. I`ve exhausted all my ideas. I have a new FPR and have tried another, all to no avail.
I can`t run my SC kit until this is sorted. At the moment it`s just pouring fuel into the bores, fouling the plugs then dies.
Thanks in advance

I disconnected the return line into a container, FMU out of the loop and still get 60 PSI on the fuel rail
With a tube attatched to the return end, I can blow down it and hear it rumbling in the tank, so no return line blockage

It`s a brand new FPR, new guage and I`ve had the rail off and checked for blockages and it`s all clear, checked the injectors, clear. I`m running out of ideas and patience now

or yet another bad (or 4bar) FPR
Or 4-bar FPR's stamped as 3-bar?
Any advise you can give EdZ would be appreciated. He has removed all the fuel lines we sent him and put back the original fuel return line. He still gets 60 psi at the rail, and the engine runs as flooded.
