I was curious how a 4" down pipe would connect up to the 3"SV.

For the guys that run them: How long, past the first bend or not?

Oh, any of the 4" exhaust guys run an evac kit to the down pipe?

You would need a reducer. I run a custom made 4" swingvalve/downpipe as well. I don't run an exhaust evac. I'm working on something WAY better for that!

You should see some Supra's. Ryan Woon's (I think it was his, but I can't recall perfectly) car picked up 50 some odd WHP going from a 3.5" exhaust to a 5" system.

50 HP doesn't seem like that much-when your're making 1100:lol:

At that level 50 hp is hard to find, especially for that cheap. :nod:

One thing I like about my 4" setup is I can still hear the engine revving out under high boost instead of mostly a whooshing sound with something smaller. It sounds different than a normal TD, alot deeper and more narly. But Iam going to have to make it exit out from under the car though (dumps right after the muffler), it's making me deaf!!!

not really, I was talking to Kevin about that a while back and being the innovater that you are, it was an easy correlation:thumb:

I have a strong feeling that an electric vacum/smog pump will work excellent for crankcase evac. And it won't be all that expensive. WAY WAY cheaper than a belt driven vacum pump like is in Jegs, Summit etc.

I thought about that as well, just had not come up if it was worth it or not. Over the exhaust evac that is. Let us know how it goes.
