I figure if anyone knows, somebody in this forum would. Any idea what the hp rating for my sled is, tests, info, documented, etc. [?]

It's a 1992 Indy 500 EFI SKS, no mods. Thats the 488 piston port Fuji with EFI.

Thanks !

Actually, I dont think that hp is correct - early 500 fuji is about 73hp while the 400cc is 63hp. The newer 500 fuji were putting out as much as 80hp. '92 Indy 500 runs best at 7.8k revs for peak power. Anyone? WL.

I want to say its about 105 - 107hp (somewhere around there) The 600s VES was putting out close to 113 - 116hp range. The non-VES 500 is about mid-high 90's would be my best guess - WL.
