ah, stupid speed based dynos!
rich, weren't some of the guys talking about twin scrolls not working well for v6's. Someone had a thread about it not long ago.
also, anyone know what the lag on a 6765 would be over a 6262? Thom tried to look up a few dyno's and couldn't find much luck. Basically a 3.0L supra engine would be a pretty close match to see how fast they spool.

there was another dyno with rpms, but i didnt post that one becuase its not relative to our cars. They were spinning the teg to 10,000 rpms. full spool wasnt until like 7500 rpms 
On our cars the 6765 would lag pretty good, not a street turbo per say, maybe 800+ rpms later. Searching for T67 dynos would give you more insight. You'd definitely need to build your motor with a 8000+ redline in mind.
but no, twin scroll is a great design for a single. Its just hard to replicate on a V motor. But already using a crossover pipe is almost all the work. Its easy on an inline motor because all the runners are next to each other.

well, considering my car was still making power up to 8k (unforunately the vortech gave out and fuel also became an issue) i will probably be reving to 8500. The engine has been to 8500 on the street...hal just didn't want to push the vortech anymore on his dyno which is understandable. My redline will be no less than 8k.

Then you need a much bigger turbo. ball bearing 6765 without a doubt

sob rich, why you throwing out that ball bearing ****!? you think i'm made of money and feel like running coolant lines? well, the money differene isn't bad but i hate the thought of running coolant lines under the car like that.
so 4500 isn't bad, that's well within what i would call "laggy" zone. plans might have just changed.

I have not, and can tell you that it will not fit. It fits the G, but not the AT. The large AT oil pan is in the way of the cross over pipe. I use a large (2.5") cross over, so I had to run in right in the middle of the 6 spd gearbox, because this is where it is highest from the ground.
