Guys, check the first page of my build thread, GaleForce's Build all the info is there under interior/electronics. I'll be happy to answer any questions there as well.

This kit is by far the best I've seen on the market thus far. Personally I just have to wait for the $$$ to keep building up.

Just buy it. I wish I had two Z's so I can put this kit on the other one. We needed a guinea pig for GTM's twin supercharger kit, so yea... That was a hard decision. It was like trying to choose between Charlize Theron and Kate Beckinsale. Blonde or Brunette, and both smoking hot.

Hard to believe you will be the first with the GTM Twin SC. Hope they give you a discount just to get it out there.

Yeah, a serious one. They are making money on all the other parts they are installing for me too. Like an extra $2,000 in labor from all the stuff I sent them with the car. It's a waiting game now. If it wasn't for the discount, the BP kit would be in my garage waiting for me.

With those two you're talking some serious horse power. :yum:

So you can order this with an option of inlet covers correct? Do you think there is a benefit of going with a ported or drilled cover?

If you are refering to the turbo compressor covers, then there is only one option due to the space limitations.

On the turbine side there are a few to choose from, depending on the HP target. These are the turbine (exhaust) housings available: 1.0 a/r, 1.15 a/r and 1.32 a/r. For a stock block, either a 1.0 a/r or the 1.15 a/r turbine housing is a good option. For those that have built engines, who wish to get well in to the 600whp, the 1.32 a/r is the only way to go.

There is no extra charge on any of these turbine options. You just tell me what you plan to do with the car, and I can help out with the options.

There is also the 67mm turbo, and that turbo is something I would go with if I was wanting to max out the turbo kit. This turbo is rated at over 900hp (93lbs/min of flow) by the manufacturer:

These are all billet wheel turbos as well, and really shine in the 15psi + range.

Sasha, No, Im talking about the shroud. There are solid ones(most common), drilled ones and ported ones. From my research it reduces or eliminates surge and also opens up mid-range. And as a makes the turbo sound more aggresive.

Here is a drilled one.

And ported.

Ok. So after knee-jerking a response I looked at your included link to the 6766. That is a drilled inlet. The 6266 is not. it is a solid design.

Vs.

So I guess im wondering if its wise to do this to the 6266? I know they offer it solid, drilled, or ported on the turbo I currently have, the GT35R.

You can get either turbo with either cover (62mm and 67mm). Straight from the PTE turbo website:


62mm turbo:
• Compressor cover options:
- "E" compressor cover 3.0" inlet/2.0" outlet
- "Ported S" compressor cover 4.0" inlet/2.5" outlet


67mm turbo:
• Compressor cover options:
- "E" compressor cover 3.0" inlet/2.0" outlet
- "S" compressor cover 4.0" inlet/2.5" outlet
- "Ported S" compressor cover 4.0" inlet/2.5" outlet
- "H" compressor cover 4.0" inlet/3" outlet
- "Ported H" compressor cover 4.0" inlet/3" outlet


I have never heard of the "mid range" being an issue to be honest. I have also sold over 40 of these turbo kits with the smaller non ported compressor cove, and have never heard about any issues with compressor surge. The SP (S-ported) covers do flow 3-5% better, and according to the manufacturer this only comes to play above 32psi.

Here is a 350z Dyno with the 6266 turbo and the open inlet .81a/r (equal to a 1.15 a/r divided inlet) T4 turbo, with the E (smaller, non ported) compressor cover:

As you can see, there is no problems here with mid range power delivery. This was also the less efficient mid mount turbo kit, and not the twin scroll I have available for the 370z here.

Vince told me that there was another 20-30whp left in this setup, but since the customer wanted 600whp, the tune was left very conservative and as is. This tune was done on 93 pump gas.



Due to the 4" inlet on the SP cover, I am not able to use it with the twin scroll kit. There just isn't enough room for the air filter, and the piping to fit in such a small space.

Listen to the man..!

Ok.. I see now.

Just brainstorming here. But have you seen what S&R did a while back as a trial for their intake? Which they didnt use as it must have been restrictive. But it was a very small panel filter that attached to the inlet. I was thinking if you took something like a turbo trumpet (inlet horn) and made a cover filter for it that it could work. You would essentially have about a 6" round panel filter. Would this be restrictive?

Lets just say when i did my twin-charge setup i had thought outside the box on just about everything, most of which did not make sense..lol.

Now make a single Variable Turbine Geometry turbo build and make history :D

It wouldnt be all that hard to do, diesel guys have been putting VNT (or VVT) turbos in older trucks for quite some time with good luck. Just need to find a good controller.

No, I have not seen what S&R did, and to be honest it does not matter to me. The proof is in the numbers, and those are posted above. If it works, why fix it?

With the twin scroll kit, this is what you get:

...and you just can't beat having a cone air filter directly on the turbo inlet.





Too bulky.
