Good God … Another one !
Q.What do you think the MAF is monitoring ?
A. Airflow … it senses increased flow and adjusts fueling…this is why I,m running richer than Boothys which has an identical ECU …
Bloody flock of sheep … [/quote]
Lol, sheep or not u are wrong, as ive already said and as has John at JSR the only corrections the ecu can make on closed loop (WOT) is knock control. The MAF adjusts jack shit on closed Loop. [/quote]
That should read “open loop” instead of closed loop [/quote]
That is why I was after the hub figures, this is a bit more realistic, if we are all looking at hub figures with the same atmospheric corrections then we are at least on the same playing field. I always use the hub figures for mine and let people add their own % for transmission losses, my cars highest has been 273hp @ the hubs, with a general rule of thumb being 1psi of boost per 0.1" in SC pulley size and 10hp per psi of boost, then your figures 243hp @ the hubs is about what I would have expected for a car with a standard pulley and full exhaust. What does surprise me is that it has made this figure without a remap
We are going to have a day which I thinks going to be for charity sonyou are more than welcome.
Ade, as I said before I felt the correction was ott however the dyno calculates it on the run down from the drag I gather. Marks totally standard car made 255 at the hubs.
Mine was a rather heat soked and shitty 230 so I think given another run she is a good 260-265 at the fly as we were poising between 3 and 5 rwhp per run.
I know my car is down on power now from its peak, I hope that the tax man will leave me alone for a few months so I can save up for the engine rebuild before it really needs it…
It is down on power (about 20hp) and I have lost between 5 and 10 mph on the straights at most tracks, i think it is just down to being a track car and a large % of its life is spent on track getting hammered, the car is 5 years old done 20k and does at least 1.5k per year on track.
You also have to remember that I was running 260hp when the car was just over a year old and 300hp for the last 2-3 years and it has taken its toll, I keep meaning to get the compression tested I just haven’t had the time
