Yeah, I do. I am waiting for a bov, midpipe, boostcontoller, and my new exhaust before I hit the dyno. Should be soon though.

I hope that I see better #'s than that for the fact that. I have the stage 3 port from Gotham. I am still trying to figure out if I want the GR63 or the GR67 kit.

I would buy a kit like that but not that one. I have been told and read that with how the down pipe is disigned it could cause turbulance in the flow of exhaust do to the angle of the dump tube. Wouldnt it be better not to have one?

Yeah I know what you mean. To find out any thing about the kit I just call Steve and ask. He said that the kit puts out very good HP and I would not be dissapointed in it.

Really, wonder who told you that? Did they inform you that as long as your further than 18+ inches away from the turbine HP loss is minimal? Also that the further you are away from the turbine the less it will effect transient response?

If you look at the pics of the kit in my sig!!! The tube into the downpipe is at the very end of the downpipe, about the furthest you can put it away from the turbine. Where it is placed it will barely affect the flow.... Sean is like a ninja master when it comes to building manifolds, his technique is FLAWLESS!!

The 63 surges like hell on a MKIV, I know the flows are quite different, thus up one to to AR sizes on a 7 VS a MKIV, but the characteristics of the turbos after that are very similar. Ultimately, a 63 will flow about 100hp less than a 67. Carl

you would gain more hp by venting but not everyone wants that. I'm sure they have a choice if it's vented or not.

I think the manifold is one of the better designs i've seen (longer runner's would be nice but it's not too practical in the engine bay). As for the DP there are no sharp entry angles (45 or sharper) and it is joined pretty far down. I also think V-bands are sexy

Just my 2 cents

Zero R and Sesshoumaru thanks for clearing me up on that matter. I was just stating what I knew and apparently I was wrong on this matter. I am still pretty new to the turbo world. I try to read what I can on turbos. This is a learing experince for me.
