Not sure about the expert thing, but here is my guess

Dyno Dynamics Dyno @ 9psi = 200kw's
Other dyno give or take 10% - 20%
Dyno Dynamics Dyno @ 19psi = 250kw's
Other dyno give or take 10% - 20%

4th gear runs

4th gear runs

BAZ my SOHC made 244 kwts (328 HP ATW ) atw with A smaller GT3076 turbo at 18psi in 4th gear
Realisticly I am looking for app 350 + RWD hp atw = 261 KW ATW :)

Thanks 4 all the replies guys . I hope to have the results before the Gatton sprints next month Lee is a hard man to pin down as he is so busy BUT I am willing to wait for him to tune it as he has built the motor & all the mods & rewired the Haltec . The other "guru "???tuner cost me a motor in less than 3k klicks Lee showed me the fuel maps and they were all over the place up & down like a yoyo wtf

I'd say around 260kw, but the power curve is going to be steep with a large turbo and the camshaft profile selection. I don't think the powerband will realistically suit autocross, also the turbo selected doesn't even come near its efficiency until 16psi (if I looked at the right turbo map). At 9 it's barely spinning :)

The stroker will definately help spool but I still think the graph is going to be rather steep.

I asked Lee for power under the curve so thats why the 84 turbine but I have to say at app 8psi it is very responsive as a Targa Tassie Starion driveing competitor who drove it a week or so ago and said he was suprised at how responsive it was .Driveability off boost is brilliant and lag whats that ???
I am only looking for app 350 whp for reliability of the drive train
I have been auto X ing for app 16 years and this will be a weapon on dirt

Well the fat lady has sung and the numbers from a Mainline =conservitive & non fudgeable dyno for a safe tune on 16psi 326.7 whp at 178 kph and a massive 588nm torque @158 kph
A DD dyno 360+ whp:cool:
