it's true that I rather have one gate per side, but really, it's only going to be about total flow rate.
In an ideal world, I would actually have a swooping pipe come off the primary into the wastegate which I would angle in such a way that the 90 degree turn through it would provide as little restriction as possible since the gates are going to be full open anyway under power.

There have been used with marginal success. We (me and my friend Garrett) looked long and hard at going serial sequential looking at OEM examples/parts, aftermarket componentry, etc. It can definitely be done, but the boost control will not be as effective as you'd like. A Jekyll and Hyde, with a some or all mentality, and no middle. It's the transition that's a bear. I could ramble on an on as I spent a good amount of time and research there. It just didn't make sense once you start adding the dollars it takes to make it function. There are other routes that can be had for WAY less money, similar results, and better drivability. Just a quick 2 cents |

All that matters is results, but from an engineering perspective, the wastegate is angled the wrong way. |

Jeesh I panicked for a second there. It's the right way.
Nothing irks me more than a 90° (or the wrong way!) stubbed WG |

There should be very little since the divider goes right up to the WG valve.

and do you need a GR testbed?

Well, at least they have a tester GR now which means progress~

We've had a larger than expected increase in demand for our products and that has definitely had an impact on the speed at which this project has moved forward. I don't see any reason why we won't start preparing for production after our next dyno session. The move to TS has been fairly smooth and the new Garrett turbine housing should only bring good things.
Correct, we have a shop 2012 STi hatch. I have just started discussing the engine with our builder. Nothing like the 2005 STi build since this is a more low key car. I'm thinking of going back to the GTX3071 with the mid-size TS Garrett turbine housing. If my calculations are correct it will be very close to OEM responsiveness and close, if not exceed, the 400whp mark. Some progress pics.... Also, will be bumping up the intercooler size a bit and considering going with cast end tanks. They do offer an advantage as far as reduced turbulence, but they come at a cost |

Initiate boner...
BONER!!!!!!! Love it. Quick question for you. If one where to keep the tubes equal length and one would not be going for max power, could you merge 1&3 and 2&4 on a twin scroll turbine and mount it transversely right at the front of the engine? I realize this isn't the way to make max power and efficiency, but how much would one lose by routing that way? |

You might as well mount twin turbos right at the exhaust ports. It's been done, with lackluster results.

Twice the turbos twice the money.
So I'd be better off 4-1 el then? |

The pulses are improper if you put a turbo under each head. The timing is way off. It'll work, but not well. The only kits that didn't perform were ones without a balance pipe for pressures from bank to bank. I have a friend who did one with a balance tube and it helped a lot. The car performed very well. Better than a single turbo twin scroll setup? No. |

I want to run a Killer B front mounted manifold with my 6262
I really like the cast ends Chris! See ya this weekend. |

I'm planning on stopping by your shop on my way to SC Chris, I'll have to bug you about this kit then and really get some info on it in person. Just did my short block build at MPS and going back next Tuesday to build the heads. This turbo setup would compliment my '11 STI very well... We'll have to seriously sit down and chat about this kit while I'm at your shop lol

I think two simple log style manifold would whoop ass, two td04's on a 2.6L-2.7L Wrx would be a sick autoX or short course car. The log type mani's are sweet, I really like how they spool. Cheap to do, relatively, too, beats tubular, surely. I really want to learn how to weld (properly, with proper school training) it's on my bucket list. /ot Looking forward to more of your kits coming to the street! |
