I have the VMAX Weber kit.
Bottled on to an otherwise standard 998. Had a few issues getting it to fit, but that was down to my engine more than the kit. Stuart was always happy to help, and sent me out some different bits to try free of charge, and was always on the other end of the phone when I needed advice. Can’t fault it at all. All looks good quality and well made.
Still need to get it set up properly though, runs great at higher revs, but bogs down under acceleration a bit at lower revs. Think it’s a timing issue.
So Danny, did you eventually get the car sorted out and any tips?

So in conclusion as now have 250KLM on it and breaking the SC in nicely (Amazing torque and pulls in all four gears - 3:44) - a few points;
- Weber DCOE needle valve had a few bits of rubber that disintegrated inside the fuel line from a useless old hose I used to set it up originally, so basically would not seal properly and gas just started pouring out the trumpets - cleaned out, added brand new OEM hose, problem solved;
- Fuel pressure at 2.5 psi as per Stuart, works like a charm;
- I have the long SC pulley hose- 1137 - but ordered the short 1125, which should add more tension and max on spin and likewise boost - right now I am [email protected], shooting for 9 out of the box and then again have not hit the magic 6,000-6,500 RPM on my piper255K as again breaking it in;
- Watch the Brake cylinder cannister as SC does NOT clear this and if you install -NOT FLUSH - like I did, will blow air out the exhaust manifold gasket (engine will run like a truck) as no matter how tight you screw those carb bolts air will get out due to SC not sitting FLUSH - So, I tapped down cannister in leu of buying a plastic new fangled smaller Brake master cylinder and she now fits flush and runs great (buying plastic cannister in fall as I want to drive the damn thing)
- You MUST do the following before buying SC - IMHO (Canadian dollars)
Lastly, DO NOT GET ANYONE TO INSTALL THIS - do it yourself as painful for a newbie like me as it was, well worth it when done and you can figure out if any issues on your own and not pay through the nose for some mechanic to experiment on yer car.
