Using a map sensor to add timing has improved throttle response noticably. 2 bar sensor calibrated from 0 to 21.7 psi (full vacuum to 7psi boost) allows the addition of 8 degrees of timing at 14.7psi (atmospheric pressure ie wide open throttle). Will get the car dyno'd to confirm how much can...

Plats are OK for FI. I'm running PK20TR-11 (twin tips) at 7psi. These are the stock plug for VVTI turbo soarers. Even if I go to a 7 heat range iridium in the NGK I still get detonation until I pull out timing. The heat range dosn't seem to make any differerence on the v8.

Won't matter provided when the bypass valve opens, air dosn't flow in the reverse direction back through the AFM. This shouldn't be a problem for low boost applications. There is no blow off valve so what gets sucked stays in until used by the engine.

Ok, I stand corrected. The power figure claimed by manufacturers dosn't include driving accessories. I don't think the SAE test method takes into account water pumps and oil pumps either.

Soarers with about 70 000km on them must be suffering significant power loss since new if the loss is only 20-25%. Stock soarers should be putting 156kw on the back wheels instead on 120-130kW as is typically seen on dyno days.

Transmission loss is normally between 30-35%. Manuals will be 1-2% less lossy as auto's have the oil pump to drive. I pulled 213rwhp so that'd be 304-328fwhp. Mods were headers and a fuel trim.

Gazza, you using your idle control motor in the setup or not? Mine ran like sh*t when first started but I had fuels leaks and all sorts of issues first start. I ended up getting the cold start installed and the rear intake machined to take the stock idle motor. Runs like a dream apart from...

Does your setup have the cold start injector? Might idle like a pig without it. If you run an aftermarket ECU then you can use the stock injectors for idle and startup, you don't need the cold start. Havn't tried without the rising rate under boost. It pings as it is. For normal driving and...

The pipe work shouldn't affect boost. The supercharger will just see a huge intake manafold volume. There might be a bit of lag in building up the boost to full pressure due to the huge volume.

Dumb question, but how do you get more boost for the same supercharger speed with intercooling or reducing engine capacity? 5 psi @ 12,000 supercharger speed M90: 28 hp @ Delta F: 95 F M112: 33 hp @ Delta 130 F 10 psi @ 12,000 supercharger speed M90: 34 hp @ Delta 185 F M112: 52 @ Delta 185 F

Genuine fluid is cheaper than non genuine. Was quoted $310/20L of Castrol Transmax-J which is what castrol supply to dealers when they ask for a T-IV fluid. Dexron will run fine in a gearbox with a shift kit.

Got a soarer with Rush headers.

Just get the shop to make one for you. It'll be cheaper than buying an off the shelf one. I had an X-pipe made when I had my extractors fitted. Not sure how much it cost for just the x-pipe but installing headers and all new pipe work was only $550 AUS. 8 hours labour ($40/hr) went into...

If you want just the aluminised steel single in, single out version, they're only $90 AU each. Got a set of these, headers, X-pipe, 2.5" pipe work, and 2 x carsound 91006 cats pulling 145rwkw before a fuel trim from a 92 motor with almost 100 000km on it.

How do I attach a file? Got a wiring diagram and map for an SMT6.
