Meanwhile, back at the ranch... I'm contemplating if a SS version even needs to exist?
I'm making a TS manifold from 304 just as a one off for testing. Please excuse the rough sketch...

It seems that if you have the TS housing options available then a SS is probably not needed. Especially with your merged EWG collector.

That's what I'm thinking... Unless the added cost doesn't equal the added performance.
Thoughts? |

How much added cost will there be? It can't be much.

The manifold requires more tubing and more welding and the 'adapter' isn't exactly a cheap part. Having not put the time in to manufacture one yet it's speculation, but if I were to guess.... another $500 or so.

I thought that Garrett came up with quadscroll couple years ago. This may be an easy application, with your design and if possible would make your kit even more unique.

Really interested in any gains realized from low mount TS vs. low mount.
Would you be running a singe wastegate for the TS set up as well (keeping the two halves separate all the way to the wastegate)? ex: how I have my single wastegate set-up on my low mount twin scroll set-up... (this shows just half of it before adding the second pipe, but you can see it divided all the way to where the wastegate would be). [IMG][/IMG] |

As far as I know there were pictures posted, but it was nothing more than an April fools joke.

very nice. Back in the day, GP Moto used to do that with the gates, but there was a big problem with the metal breaking off from the constant side to side pulses fatiguing it.
Your design looks stronger right off the bat, but have you addressed that potential problem? |

This cast adapter is our part. Garrett was very helpful in providing their housing data/dimensions, but this parts was not sourced from them. |

That seems like a pretty cool fabrication part for a lot of other applications. Thinking of selling it separately and/or designing a T4 flange version?

That's a bit more than what I would have thought. What value are you putting on the adapter? Since its cast what qty are you amortizing the tooling and mold cost over. You designed that as a stand alone part and it has good potential for sales across many platforms and this kit as well.

I love how the twin scroll header change simplifies the entire setup. I am seriously considering buying an 04 simply to get to use this part sooner, as I know it will be years before you get to changing the design for my 09. your expected cost for the kit is more amazing, when you consider a good rotated kit is in the ball park for what you are asking(assuming the turbo is included in that ~5000 quoted price).

Unless the shapes are too complex and then the welding was cheaper if the bender rapes you. The other way is to make the cast part 4-1 using the same wastegate merge. The diesel study says that split pulse should perform like a housing 80-90% of its size in a single scroll and produce torque curve like a housing 60-70% of its size single scroll. Seeing as how garret now offers .83 and 1.01, which matches .63 and .82, I don't see a need for single scroll versions. After actually reading the study, I think their conclusions were spot on for the most part. Peoples expectations have just been unreasonable. I've been looking at graphs and found that the study was pretty accurate. |

There's more tubing and if you look at the CAD sketch you can see the secondaries spiral from over-under to side-by-side. The geometry is tight to the point that it can't be formed and will require more fit-up, fixturing, welding and finishing |

Well, I'm planning on saving up money for this...
I'm awaiting GR results as usual |

Intercooler piping?
BTW I'll volunteer for the GR/GV kit beta test if you need someone |

Were you planning on running an open dump from the EWG or will there be piping into the down-pipe? i saw you mention there will be a dump tube in the kit above, but wanted to check....

I'm running an open dump right now. I was really surprised how much you can get it to scoot without opening it and scaring the b-jesus out of everyone. Although I do enjoy the WTF was that expressions from innocent bystanders.
Going recirc means a larger than 3" cat-back IMO to get anywhere near open's performance levels. I'm not quite ready to take that one on yet. |
