Just want to clarify something I wrote in my last post due to a few surprised comments I received; the rwkw figure I posted was what the machine printed out, not a number I plucked out of my arse. It is a Dyno Dynamics unit that has been commissioned and operating for 24 months or so. The guy operating it is accredited and I asked him if it was possible that my hp reading was too high, I don't want to sound like a dick when I quote his figures. He said that due to the fact I don't have air filters, he hung the air temp probe to the trumpet instead of the insulated air filter material and this may have caused the probe to be susceptible to heat soak. It could affect the hp readings by 5% - 12rwkw. Additionally, he detuned the map slightly to eliminate a slight ping, so the final HP peak is 235.5rwkw as shown on the report, subtract 5% gives you about 220rwkw.
As far as the machine is concerned it is fully calibrated and has tuned many vehicles, and their hp figures have been duplicated on other dynos.
Whatever the number is, it feels quick through the seat of my pants and that is good enough for me. I'll post a copy of the hp readings soon.
Hope this clears things up...
