These are aftermarket throttle bodies that were installed by a previous owner. The car is a 1999 GTS ACR. I can't find anything that looks like these. I'm not surprised given the age of the car and rarity of Vipers in general. My best guess is they were discontinued years ago...but by who? No markings that I've found anywhere on them.

Those Accufab are the closest I have seen, but not the same. Maybe an older version? The blades also don't have any markings, so maybe custom or Chinese?

I could see them maybe being an early prototype set as well. I think a lot of times companies will put a feeling out for customer cars to use to develop new products, and with the limited number of Vipers out there I could see that. They are also simple enough looking that I could see them being homemade. They don't appear to be very complicated, but that also seems like a lot of work if the car doesn't have other mods that would benefit from it.

Thought I'd throw a little bump on this. Anyone else have an idea of who made these throttle bodies?

I do not. The broad consensus back in the early '00s was that the intake manifold is a performance bottleneck plenum volume/runner length and that oversized TB's made it more inefficient than keeping the stockers.

Been a while, figured I'd bump this and see if there were any new thoughts on who these throttle bodies were manufactured by.

I have a set of the same TBs, but do not know the make of them. To utilize the bigger opening, it would be best to have 1.7's and maybe ported/polished intake. that said, I am selling a ported/polished G2 and G3 intake. they do work well with the Havik Performance camshaft
