Hi, all!

I have a somewhat modified 911SC Targa. The engine is originally a -82 180hp US unit, but has been rebuilt and has basically this configuration now:

- 911SC intake, small port, opened to 39mm.
- Heads ported to same size.
- 964 cams.
- Euro cylinder set (3.0l)
- Maxxecu EFI, DBW throttle.
- 964 oil pump.
- Stock rods, but with ARP fasteners.
- Stock crank.

It makes 218 WHP on the dyno and runs really great, but power is dropping like a rock from 6500 rpm. Torque peaks at 5500. I guess that the stock intake is really showing its limitations.

A friend of mine has a complete 993 VRAM intake I can have at a very reasonable price. I am thinking of swapping my stock intake for this and control all the flap features through Maxxecu. I am then also contemplating a new cam, maybe going wild with something like a DC80 cam, combined with raising the rpm limiter to 7300rpm (7200 today).

What do you guys think about this? How much power could I gain? In my head it should gain torque all the way and quite a bit of power as well after 6500 rpm. In theory it is quite easy for me to change out “just” the intake and the cam, so I am really tempted. Unfortunately I can find very little info about using 993 VRAM intake on my engine, so I am a bit unsure of what to expect.
