4WD manifold is not the restriction thus far even with my 284kW atw...Phil, Yavuz and I have done comparisons, engine for engine, same dyno...More testing comparisons will come with Phil's new engine...Further my engine is the apparent "least awesome" version being the first YBB bog stock[8~2]..."They" say the later engines are better, this is likely as of course tweaks and improvements would be made over 8 years of production[;^)]...Happiness in the end is driving...That we all agree...

here my dyno print out , running a gt30/76 ,pump fuel,bd16 inlet cam ,bd15 exhaust,ported head and 8.0 comp..
 
thats at 22 psi bleed back to 18 ish

Cool cannot read that bottom scale - got a better pic?


Feel free to add mine to the pile mate.
This was about this time last year just after the ECU was wired in. It still needs to go back for fine tuning. I have been busy with "other" mods!
Spec is running a GT2863R, MoTec M400 with wasted spark ign, Sard 1000cc injectors, 12mm plet spacer. All stock internals with the usual other mods including big FMIC, pod filter and 3" exhaust. 




If I knew how to download. A dyno sheet I would !!!
