I have seen on here in a few different forums that some of you have used tb's bigger then 60mm. Can you tell me what kind of tb you used and how you matched it up to the manifold? If you have any pictures of the install can you post them for me? The reason I am asking is I saw that someone said that Karo has a 70 or 75mm tb and well his hp and tq numbers were impressive. If anyone can help with this I'd appreaciate it.
