Holy crazy piping scheme, batman. Looking forward to seeing results. Please start a new thread for your kit so we can follow its development. Love the twin scroll design. On STis, you could pick up several hundred rpms in spool using twin scroll. Will be interested to see if in your design it offsets the loss in spool from moving the turbos away from the block.

I will start a thread in about a week or so.

Also, this will be the quickest spooling single, because nothing out there is closer to the headers than this. The top mounts are much further, and the STS is..well, in the back of the car.

This will compare very well to a TT kit, because the pulses are kept seperate.

<3 on your kit. I will be buying one when ever they go into production.

Would be interesting if you would do a twin turbo mid mount setup too. :tup:

A true twin scroll with equal length primaries, utilizing the firing order of the VQ. Nothing like this out there. This will also allow for big power because it will be a true T4 with options up to 1.32 a/r.

Will be using the all new Precision 6266 and 6766 T4 CEA billet turbos.

I will be a sponsor here shortly.

Wow. The welds look great and looks you all have got a good idea going can't wait to see those numbers

Yes, should arrive some time next week, with a FI exhasut system. I will have two downpipes made, one for those that have a FI exhaust system and one for the OEM system, where the down pipe will connect just before the exhaust splits in two.

Will have a full build thread soon.

This looks great my STS starts boosting at 3600 and in full boost by like 4200 that'd be awesome if you could be full boost at 3600

I think STS uses a small T3 trubine, so it will spool quick and will limit your power due to flow restrictions. What is the a/r on that anyway?

blackonorange 03-27-2012 01:29 PM

I wanna say .57 and it's the ball bearing turbo as well I that means anything to you

to clarify no i am not his test mule as the "free turbo" car, that is someone else who is like batman and will remain unnamed i guess..

i will however help Sasha out in giving him access to a pro tuner we have both worked with before and his comments will help him out fixing anything with the kit.

I will also show everyone how simple this kit will be to install and give as much detail as i can to help Sasha out!

With that setup, when I buy your kit, I will run into problems lol. i think the nismo guys have it connected at a different spot.

It is more than likely a T4 .58 then, and that is very small and is the reason you are spooling that quick with a turbo that is that far from the engine.

R&D on my end (on the VQ) shows that you need a T4 .81 for about 600whp (DJ) on pump, and .96 a/r if you wish to push things past that. (.58 T4 = .7x T3)

I find it very funny when a manufacturer says "600hp" turbo. That is great, but it is only the rating of the compressor wheel, and not the turbine. So you have a large compressor that will flow 65lbs/min of air, but you have a turbine housing that can only flow 50lbs/min....and THAT limits you to about 500hp. So you can have a turbo (compressor) that is rated to 1000hp, but if the turbine stays the same, all you will get out of it is 500hp.

Fluid dynamics will never cheat you, but somebody selling something will.
