Well we are sort of in agrement. I just think you maybe 20 more hp than you
think.
My experience has shown 180hp for the 2lt and 200hp for a twin spark to be a
resonable expectation for a race engine if its going to last. If I had a
spare 60k Aus Id ask benica to build me one of there 700 hp turbo engines. I
dont think they would last for to long before a rebuild so I would have to
give em another 20k every race or two. At times they have been seriously
commited to racing Im just an amature with no budget so I cant afford things
like monoliners. Some of the guys here get 340 360hp from fuel injected
3.4lt V6's. Thats impressive!
Cheers,
Dean
