Why is there such a large hp difference between the Vette kit and the GTO kit? If the two engines are practically identical, how can one produce so much more power than the other? Here are the two dyno charts.
Vette

10.5 psi of turbocharger boost pressure in the mid range trimming to 9 psi near red line results in outstanding power and torque.
GTO
http://www.airpowersystems.com.au/ls1/us_gto.htm
The above dyno chart compares the Power and Torque at the wheels of a stock LS2 GTO and the same vehicle after the APS Intercooled Twin Turbo conversion. Note that engine tuning was performed using the APS engine management system (93 Octane map) and a zero backpressure exhaust system.
And before some of you chime in, I know the vette's dyno pull is at the crank and the GTO is at the rear wheels. But it still seems to be quite some discrepancies... And I see the boost of the vette is 10.5lbs and the GTO is 6. Why can the vette engine handle more booste than the GTO engine? And if we crank the boost of the GTO up to 10.5 will it produce the same HP as the vette? Peter shed some light on this subject please...
