I don't really have to ask per se, but it makes life much easier if the purchase is ok'd by the wife lol. She has been really cool and supportive of the whole ordeal thus far. I don't want to push it too hard and piss her off lol. You know how women are.

Cell I actually already picked up a second job so I could get it all done before ZDayZ lol.

DAMN!! :eek: Sign me up. I like the idea of less oil lines and a thermo plate. I also really like the new layout of the IC piping.

sasha, have you tried to see if your setup can accommodate a borg turbo? like the new s362 fmw?

No I have not. The Precision 6766 will outperform the S362, so it is not worth looking in to. The 6766 is rated to flow 93lbs/min, and the S362 is at about 83lbs/min.

Also, the BW turbos use massive compressor covers for some reason, so physically it is much larger, so I don't think it would fit well.

any updates on progress sasha?

Sorry, no news that you guys would like to hear.

I have been put in charge of some major projects at my "day job", and it is eating up a lot of my time. I just haven't had much time to work on the kits. Hopefully things slow down a bit in the near future so I can get a few kits finished up.

Wish you were closer, I would work for boost products haha.

:( maaannnnnnn I was hoping for good news!

Yeah, sorry guys. I do have 4 V1.5 kits that are 75% complete...just need to find a bit of time to get the rest of the parts fabricated.

How's that diff bracket coming along Sasha? Going to have any for sale at the Dyno Weekend in June?
Time permitting of course... Gotta get those Boosted kits out!

Have a couple of questions.

Love this kit immensely and it seriously has me questioning my original Stillen SC plan. But something just sprung to mind and it's mostly just nit-picking and likely to have very little effect one way or the other.... but this is a Twin Scroll Turbo setup.

Given the nature of the design and why it was thought up in the first place, Single Twin Scrolls are typically most effective with 4 Cylinder Engines (and Dual Twin Scrolls on a V8) where the exhaust gasses can be easily split up in pairs. I've not really seen any V6 engines using Twin Scroll setups given their cylinder firing order. Is it really worth using a Twin Scroll Turbo rather then a traditional one for our application? Or was the Turbo selection not made with it's Twin Scroll function in mind?

This illustrates what I mean:

For those curious, this is a great explanation of a Twin Scroll Turbo application & purpose:

Also, being that close to the Gearbox/Transmission, I'd really feel much more comfortable with wrapping every bit of exhaust down there in the best insulating wrap available, and even look around for a suitable Turbo Blanket/Jacket to slip over that thing. Do you foresee any issues with this? Or any tips?

Cheers,
MoulaZ

I wrapped my silicone wastegate/controller lines, JWICK did everything.... other than that, nothing is by the manifold pipe that would not be subjected to normal exhaust heat, I have inspected the setup many times to ensure I see no heat problems, thus far none, I just hate what exhaust wrap does to the pipes, a guy a work may ceramic coat the manifold over winter for me. As for the twin scroll, I believe it works, Sasha has 3 cylinders feeding one side and 3 feeding the other, its not one collective exhaust mass moving into the turbo. I will dig up a vsr dyno graph, if you compare that to the BP kit, you will se how much sooner this kit builds tq, I just attributed that to the twin scroll, but I guess I could be wrong, Sasha will tell all!

Ill let Sasha answer this, but for what its worth the BMW N55 engines have a dual scroll charger on their inline 6's.

Also I have about 20,000 bagging kms on my kit with 0 issues where it is placed. You can wrap it if you want but the amount of air moving around it doesnt allow enough heat to build up.

I wrapped everything but I'm an engineer and don't like to take chances. There's pictures of header wrap and thermo-tec on all wires and hoses in my build thread (link below). I also check zip ties all the time to make sure they aren't melting and I've not seen any issues

I was also going to mention that the BMW went from a twin turbo N54 to a twin scroll N55, although some say the N54 made more power.

Also, the advantage of a twin scroll has to do with the order of firing pulses. Because the Z uses 1-6 firing order on alternate banks and Sasha made sure to keep each header equal length, the pulses will enter the split turbine housing alternately which adds to the efficiency.

I'm sure Sasha can chime in here with more info.
