Oreo, thank GAWD you've retained some of the stuff I seem to have forgotten... Well said, sir.
Meanwhile, back at the Bar D (for Duratec) Ranch...
Though the thread title says "quad throttle body" I don't see how an air metering device developed for a 750 cc displacement would benefit a 2261cc displacement especially when final power figures are taken into consideration...
Now, I haven't checked Mr. Stranahan's link, but let's say we're shooting for an even 200 at the Duratec's fly... Do Suzuki GSXR 750s make 200 HP? I honestly don't really know. I know that Hyabusas do, but they're almost twice the size as teh gixer.
