V-Band Reducers, do they make them for my application?
 

I am going from a TD07-08 to a AF61R turbo. Now, my TD07-08 used a 4" vband output while they AF61R is a 3.5" outlet. I have a custom made 4" down/midpipe and I want to reduce the 4" flange on the downpipe to a 3.5" flange so I can clamp it up to the new turbo. I was curious if anyone has came across anything that will do this. I know they have reducers for the turbo side, perhaps I can put one on my downpipe?

ANy input would be great. Thanks

Ron from Davinci (DR Autoworks) can have that done before he ships it off. You'll have to add a couple extra bucks but he can do that for you.

Lupe, he can reduce the turbo side. Unless I can get him to expand the one that is on the turbo and make it a 4" - I rather enlarge the hotside to bolt right up, that would be easiest. I called him earlier, I'll explain it to him tomorrow maybe he can do something.

Hopefully I can get 500hp @ 20psi with a large street port and my mods, watcha think?

When I bought my 60-1 a few years ago the fella from TiAlSport that sold it to me spec'ed it with a 3.5" v-band weld-on bung. I don't know what the housing looks like on your turbo but if it's got a 3.5" port to accept a weldable bung, there may be a 3.5 --> 4" bung similar to mine..

Pics are worth a 1000 words.

That is exactly what I am looking for =) Glad to know they make them, lets hope the shop can help me out!

It can most def be done with race gas :)

Burns has some SS reducers in two grades. I welded the flange to it and went up in size from 3 to 3.5.I dont see why it cant be reversed using the 3.5 to 4.0
