-To anyone posting this on a website or message forum; Please let the author be of this chart(Sam Karp, karpsam@hotmail.com) be know for any corrections or errors. The above rank list is determined via differences between all of the aftermarket cams compared to Civic Type R cams. Ties in the rank list are broken by taking the cam that has proven more peak power as the "better" cam.

-If anyone wants this e-mailed please post up . If anyone has a problem with the rankings/specs......go poop yourselves...I spent a lot of time on this...haha J/K...let me know your thoughts.

Yeah it is very close between the two.

I think the Toda C is more streetable so it can be reversed.

When I made the list not many people had the Stage 3's though and lots of info was saying that the off-VTEC was same as the Stage 2's(much like Toda B and Toda C having same off-VTEC).

There are some that are so close that I just had to go with the more dyno plots I have seen and since I have only seen one of stage 3's and severl spec c's I went with spec c's. Kinda a bad way to pick it but most people get the idea that anything over JUN III is nuts!!!
