Was in DC the other day for the Red Bull Global Rallycross race and saw this type of system. Its been around for a long time so not sure how I missed it. Thought it was some kind of 2 stage wastegate setup at first, lol.  I doubt this is as easy as plumbing the diverter valves to kombi valves to feed the sai ports, but I like the idea of boost in the charge pipes, regardless of what you do with the throttle  22psi at idle would be nutty!!! http://www.cosworth.hu/?p=77 |

If you have a cable throttle, by all means, get this.

Im sure I got some cable around here somewhere!! This looks like taking a turbocharged engine and turning it into a gas-turbine pumped engine. I saw that and started wondering if we could turn the secondary air injection into primary air injection |

Useless on any modern car with e-throttle.

One of the crew guys I was talking to said the Super class cars were in the neighborhood of 600k. Im pretty sure if it were useless, it wouldnt have been on there. Looks like this type of system can make boost on its own, independently of whether or not the throttle is open or closed. My guess it has the ability to maintain psi in the charge pipes while engine braking and can supplement the exhaust gasses to spool the turbo sooner. |

Can our current implementation maintain spool while completely off the throttle and engine braking?
Can it kick in to help spool the turbo if you shortshifted and bogged the motor?
That stuff sounds like it could be useful to me.

No, but then again this isn't WRC. |

What if I drive like a WRC driver? Oh wait, youve seen logs of my driving Just seems like a neat way to do things and would be pretty easy to do on our cars. Some cars are driving off the lot with these systems installed for homologation purposes. Sounds like it just needs to be turned on in the ecu for them to be functional. Seems like you could potentially make something like 770s or k24 hybrids spool like k04s, or maybe even k03s. Im thinking put the kombi valves on the heads, plumb one of the diverter valves to them, another n249 or n112 to control them, and some mojo in the ecu. Who wants to be a guinea pig?!?! |

I couldn't imagine doing this on a car that the turbos are this difficult to replace. Anti lag while entertaining is very detrimental to the turbos longevity.
