T3 vs T4 1.06 twinscroll housings, any power/response difference?
the neat part about using a t4 twin scroll turbo setup is that it can accomodate turbos that can produce 600 to 1200 hp by just swapping out the turbo and nothing else. You cannot do that on a 2 liter motor with any other manifold setup on the market, none of them, be it t3, t3 twin scroll, or oem twin scroll
i do not need that. i was just stating its the same wheel
I find it interesting that some people think that a T3 TS 1.06a/r will destroy the power potential of a turbo like the 3586. However, people like me and Mike at AWD have 700hp out of a stock cast 1.25" manifold with the extremely small stock TS housing on a Black...
So... If you go to a 1.25" tubular manifold (flows more than the stock cast), T3 TS 1.06a/r housing (much larger than stock housing), and upgraded to a 3586 (larger than a Black) then why could we not make 750+hp with great spool and topend? I would be willing to bet, a setup like this would only spool 200-300rpm slower than the Black and make a good 50hp more.

The 67mm turbine stuffed into the EVO housing actually means a good deal of the nozzle is cut out of the housing. That stock housing may not appear all that large, but with a good portion of the nozzle cut out, I bet it flows considerably better then its size suggest. Cutting out the nozzle probably hurts efficiency though and having a better sized housing would likely show gains in mid-range. I don't think it would give you much on top end though as you are likely compressor limited at the 700HP level.
I don't think the stock runner is similar to a 1.25" pipe. It seems similar in cross section to a 1.5" pipe runner. I have not measured it deep in the runner to be sure, but I would beleive the stock manifold is much closer to 1.5" then 1.25" at its smallest cross section. Also, the stock evo manifold has a pulse converter shape cast into the runner to help reduce reversion... Look into this and get back if you think it is beneficial. I think it is especially considering the high EBP levels you are likely seeing at 600+ WHP. There isn't another aftermarket EVO manifold out ther that has this feature.
Full-Race FTW
