Yep, with those mods you should expect at least 120 rwkw. But don't despair! Get your car checked at another dyno, cos there can be big variations from dyno to dyno, and all other issues I believe, such as weather etc.
XR8 Chick, I wouldnt say condition would be the right word, instead how good the factory bolted it together. I compare same cars (brand new) and the difference is a real eye opener. I reckon the difference between identical cars would be as much as 20 RWKW from the factory, remember the Street Machine article about the 3 EF's? even after all the mods to all of the cars, the other 2 didnt match what the stocker put out to start with:crazy1: and the stocker got the mods as well as hardly improved at all. She was just a factory jet.
What matters is not so much the RWKW figure as Dynos do differ. What is important is to measure each mod on the same dyno under the same weather conditiuons, this will give you a benchmark of how effective each mod is. It will also negate the variations from different dynos. To put this to the test I have done my HSV - dyno`d 218 rwkw and 212rwkw on two seperate dyno dynamics, same day. I had also dyno`d on both before my latest mod, and both showed almost the exact power gain from this modification.
