And how many miles or km has the first installed car run so far? I'm curious about the durability of the stock clutch.

Boost and a/f monitoring IMO are good to have. Things like oil pressure/temperature I would say are not needed, but people have preferences. This is why no kit out there includes gauges...there are too many to choose from.

As for milage, I am not sure to be honest. I can tell you that there are enough miles on it to destroy the OEM clutch. New clutch was installed a couple of weeks ago, still in the breakin stages I think.

I think that with this kit and a stock clutch 8psi of boost will be the norm. Remember the kit made 513whp (peak, see first post) and the boost pressure at that point was 8psi. The kit is very efficient, and puts down a lot of HP/Psi of boost. The broad torque curve is a big factor when it comes to clutch holding power, and the OEM is just not built for it.

New clutch is still in the break in stage. The factory clutch only started failing when it got cold. If your in a warm climate you may be able to squeeze a little more life out of it.

Just out of curiosity, what clutch did you go with this time?

JMac88 10-03-2012 12:30 PM

Specialty Z 6-puck. Impressed with it so far but since its still breaking in, I have not pushed it yet

m3chhawk 10-03-2012 12:52 PM

Might go ahead and do mine now so I can get it broke in before the turbo :D

wheee! 10-03-2012 12:54 PM

Good idea, less to disassemble when adding the turbo later!

I should think about this too. My Buddy has the specialty Z clutch and likes it as well. Just recently got my fast intentions so I'm good to go there, but I doubt I'll buy this before next year it's already Oct!!

Another few pic of the jig here. As you can see this can be very time consuming, but at the same time must be done right, with high percision.

With the piping out, you can see how it would be very difficult to make a set of pipes that don't fit just right:

http://i137.photobucket.com/albums/q...d/IMG_7587.jpg


I also got a new 6266 turbo in a couple of day ago for a local build, so I thought I compare it to a turbo that is very common on the VQ twin turbo kits out there.

For starters, have a look at the turbine housing difference in size:

http://i137.photobucket.com/albums/q...d/IMG_7580.jpg

http://i137.photobucket.com/albums/q...d/IMG_7577.jpg

http://i137.photobucket.com/albums/q...d/IMG_7582.jpg


The twin scroll turbine inlets are the same size as the entire inlet of a GT28 (T25) turbo. This is one of the reasons the twin scroll is so efficient. You have both banks (exhaust) powering/moving onc turbine wheel and one compressor wheel vs. two of each.

The exhaust side of the turbine housings:

http://i137.photobucket.com/albums/q...d/IMG_7581.jpg

The compressor wheel of course will be much larger as well:

http://i137.photobucket.com/albums/q...d/IMG_7575.jpg

And of course, this is the business end, a 62mm billet compressor wheel:

Boosted Performance 10-05-2012 12:02 AM

Well, I think it's safe to say that the most complex jig I have ever built is complete:

http://i137.photobucket.com/albums/q...d/IMG_7590.jpg

http://i137.photobucket.com/albums/q...d/IMG_7592.jpg

http://i137.photobucket.com/albums/q...d/IMG_7593.jpg

Now it is just a matter of getting all the bends, placing them in the jig, and welding it all up. Like lego:

http://i137.photobucket.com/albums/q...d/IMG_7594.jpg



I have received a number of PM's recently from people that can't wait for this to become available. All the jigs will be done by the end of this week, and at that poing I will start the "official" production. The plan is to get 6 kits built as soon as possible and get them ready to go.

Deposits of $3,000 will be taken, and at that point the following will go out:

UpRev EMS
750cc Injectors with clips (plug'n play)
340 lph fuel pump
FMIC
BOV
Waste gates
Scavenge pump

The turbo will have to be shipped to me first for the compressor outlet modification (welding a cast 2" 90deg elbow on the outlet). As soon as that is done, the rest of the hardware will be ready to ship. At that point the balance is due.


I have already made 6 sets of FMIC brackets, oil reservoir tank, and scavenge pump brackets. On order is a lot of stainless braid hose with fittings, so I will be making all of those shortly as well.

Its awesome that you are sharing all the steps that go into building the kit. The purchaser knows exactly what you are selling. I also like looking at the top notch craftsmanship.

I have nothing to hide, and I know that a lot of you guys are interested in seeing how it all comes together. To me it is important that the customer know what they are purchasing and what it takes to make a great product.

Nothing is outsorced here, so each kit is built by me, in house so that all the QC is in my hands...the way I like it.

wheee! 10-05-2012 12:43 PM

Congrats Sasha! I think you have done a solid job promoting and developing this kit! Looking forward to hearing all the reviews from new customers...

Boosted Performance 10-05-2012 12:45 PM

Thank you. As much as I would like to sell you a kit, I must say that you should put the money towards college. In the long run, it is a much better investment.

SS_Firehawk 10-05-2012 02:52 PM

OMFG, I just saw that dyno chart. I couldn't look at photobucket so I CTRL + the sh!t out of my web browser. What's in the tuner kit? I have an oil cooler and uprev, just no downpipes. I didn't know it was thaaaaaat serious. When do we have to pay, I can put something together lol. Holy ****, was not expecting that kind of torque curve... or lack there of.

wheee! 10-05-2012 03:11 PM

Time to take the company public Sasha! Where do i invest?... :roflpuke2:

elperuano 10-05-2012 03:14 PM

Granted its a single turbo, a big one that is more or less along the lines where the torque should be no?

Great kit Sasha, definitely would like to see these on the streets!

You can visit the the link in my sig. Tuner kit = everything except fuel support and UpRev.

And yes, the kit makes excellent power all the way to 7500rpm. There is another dyno with a bit more boost (9.12psi I think) and it made 550whp at that boost pressure. The tuners (who have tuned a lot of these car from TT to s/c kits) could not believe how flat the torque was. The kit clearly works very well, and this is the efficiency of the twin scroll that I have been preaching for a while now. It really is the best way to boost a car. Heck even the new BMW's now go with a single twin scroll vs. the old TT kits.

EDIT: found the 550whp dyno pull:

Link: http://i18.photobucket.com/albums/b1...scan0001-1.jpg

Looks like peak power was made at 9psi.

Thank you. Torque can be controlled with timing, and is usually done to keep a motor going for a long time. In this case an engine that was N/A from the factory with limitations. It is also an indicator of efficiency.

That would be awesome! All the base maps are provided by Vince@R/T, and this would really help with diling things in on that end.

What is the additional cost for recirculated wastgates or is this now standard?
Also, high flow cat option?

sojirovskensi 10-05-2012 04:14 PM

Payment sent!
Am I the first one who will be receiving the kit?
This is such a perfect gift for my baby's 2nd birthday (even though it is late by a month, so I need to make up for it! lol)

elperuano 10-05-2012 04:17 PM

The graph says 12lbs of boost. Made more power at 9 than 12?

G37sHKS 10-05-2012 04:19 PM

Woow!! now look at that flat torque!

Might sell my GTM TT and get this!!

elperuano 10-05-2012 04:38 PM

The flat torque is nice, however for entertainment purposes it's at 411. With my Gtm TT kit on my graph the lowest point is around 411. But the highest point is 496. I'm still very happy with what I have.

Recirculating is standard, and no high flow cat options at the moment.

At peak power of 550whp, the boost was 9psi, not 12psi.

As mentioned before, torque is a function of timing. The more agressive the timing, the more torque the engine will put down. I can provide countless dyno graphs to support this.

I have noticed that GTM dyno charts are very aggressive early in the rpm range. You can tell that by the way the torque goes up out of the gates, again, early in the RPM range. A lot of tuners will avoid this on stock blocks because it is a lot of stress on the engine. If you look at the 550whp chart you can see that the boost is already at 10psi by 3750rpm, so if the timing was advanced the torque would have shot way up in the 400's. Then as the RPM's go up, the torque would taper off. Instead, a nice smooth, flat torque curve is simply easier on the engine, prolonging it's life.

EDIT:

Here is a perfect example of the same kit with a different tuner:

http://wrxatlanta.com/forums/showthread.php?t=29246

Note the torque curve between 3500 and 4500rpm...easing into it. I

I am not arguing your numbers at all, or the kit it performs great. Just noting how timing/tuner have a large role to play when it comes to presenting the final graph/numbers.
