what sort of torque is it making? and did you up the boost much?
by the looks of the graph and my limited knowledge is it your cams holding you back! or is that wheel spin?
...2008 results yielded 263kW at 24-30psi, more boost simply brought the peak power earlier without increasing the top number. The dump pipe has been replaced and all components ceramic coated, timing reviewed, new sensors and now at 27psi gives a result of 280kW...BP ultimate fuel, nothing special used...Apparently the top figure for this turbo (GT3076R) is around 320kW atw as a guide so not far off; next - we expect cams and head porting become essential...Depending on who you speak to everyone has a different opinion for what is the limiting factor...For now I am happy with the car's performance so there is no need to rebuild and chase more power...What I would seek is more power earlier (we all do)...

...CheeRS Peter - now you should have a look at what you can do to get a few more hp, maybe crack into the 30's...It is great to see the car out and the power it makes is just a number....Go the mighty 1300 auto[88]

He almost made that in additional horsepower...[:x)]
Great work Mark, good to see you could squeeze the cossie a bit more.
...At the next Dyno Day we'll try to squeeze some more...

A graph for comparison: DISCLAIMER 1. This is for comparision only 2. The flywheel power is just a number and based on dyno figures times 1.25 for losses (yes/no or other it is just a figure) 3. One could change this to any other percentage, so take it with a grain of salt. Sumary: This is most useful for potential torque figures more importantly indicates the curve...CheeRS.

Now just have to equate the power to times on the track.
