I am a bit cynical on the benefits of larger tbs. Having said that, I run a 65mm Accufab.
Takes a bit of an oddball hose to go from the stock uppipe to the 65 mm tb. Seems like it was 2.5 to 2.75? Probably a 3" to the 70MM?
Looks like you have a pretty quick car...If you want to spend the money, Might as well go to the 70mm, I don't see any real harm. I kinda doubt you will go any faster than you would with one of Jay Jackson's modified 62 mm units but the polishing and workmanship are nice on the Accufabs.
You might compare the pricing of buying the tb by itself and a PTE/Power Plate combo from RJC.
I think Jason is running the 70 mm tb with his PTE/Power plate and is into the nines....he has a lot more under the hood than that, tho', so I am not telling you that you will run nines.. LOL
