How's this ported TB look?
I don't agree. Removing half the shaft and knife edging will improve flow. It may not show any gains depending upon what the car needs. If the TB becomes the flow restriction, then I gurantee it will show a gain. If it flows more air, and it becomes LESS restrictive, it will make a difference. If you dont need the extra flow, it wont make a difference.
Half the shaft IS removed in the pic.
Just leave it and throw it on. It looks good to me. And for what it's worth I would trust Ron@Vengeance well before anyone else just throwing information out there. Like he said, he's done thousands... And the company speaks for itself.
No to epoxy! I see this too many times ---> https://ls1tech.com/forums/generation-iii-external-engine/873208-epoxied-ported-throttlebody.html
