Just watched the video - what are the details on this?
Are gen 3 heads a direct swap or were parts like timing components needed from the gen 4 engine? Were the gen 4 cams used?
Interesting stuff!
@beefcake
are all the big shops posting numbers right now using the same whipple tune or has it been customized for each?
And if so, is each shop going to be selling that particular cal in the future or?
If you ever want to supercharge in the future....yea the Whipple kit for the S650 might be $9-10,000 but you need to see what C8 stuff costs...The ATI ProCharger kit is $19,000!
And if tuning ever comes out for the S650 you should see kits in the $6,000 range like you did for the S550.
20-30hp isn't uncommon. If you see more than that there are usually other mods that came with it, or the car wasn't tuned prior to the headers but was tuned after, etc.
Throttle body size doesn't really matter on centri/turbo like it does on a Whipple. People have gone 7's on the twin 65mm Cobra Jet TB with a ProCharger
