He answered that a few posts above.
As for the kit it looks promising and I love the way you designed the turbo manifold it's really a slick Idea. Have you posted this on Performancetrucks.net I feel like a lot of guys would really be stoked for this kit.
In for more progress on the build and testing.

Yes should not be very long at all, we hope to be getting the first kits out by November. Im overall really happy with how the kit goes together and its a clean, simple design. A lot of guys are going to have some fun with this system, thats a guarantee

Also just to address the ls swapped foxbody question, we have also clearanced everything to fit the 88mm turbo as well. Fits nicely on the truck and foxbody application, there is however one modification needed. The vband outlet on the turbo is 3.5 vs the standard 3" so if you go with the 88, it will take a cut and weld. I dont have a jig setup for that yet, Im sure we will sometime down the road if enough guys upgrade to that turbo option

I'd like to be the lucky owner of that lsx turbo swapped fox!
On a side note. How do you think towing would be with the kit on say a 2500hd.would temps get out of hand or anything?

I have a friend that built a similar car that daily drives it and its a work vehicle. Runs no different than when it was stock besides for now its a low 12 second truck. Ill be using mine to pull when needed and daily driving.

And by other side I mean of the passenger log, I just want a picture of the motor side, not the fender side.

The waste gates ONLY job is to regulate boost. The closer to the turbo, the quicker they regulate boost. This is especially critical when you have 2 engine banks merging in to one. You could also place a gate on each bank after the manifolds...it works...but when running actual boost controllers that cycle the gate one single gate works better in my opinion.

Man Atomic, you are taking a beating over here. Everybody on tech are experts on everything. Obviously wastegate position in the exhaust stream is going to have an effect on how well it regulates boost. When a manufacturer rates a wastegate spring at 8psi, but you are getting 10psi with your set up, obviously your gate position is not as effective as the manufacturers. That is all Richard is asking. How efficient is the gate location in that particular hot pipe set up....

2 things will effect the pressure. If yours seeing 10 out of an 8psi spring that's a result of higher back pressure, and/or where your getting your boost signal from on the bottom of the gate.
Typically guys that have boost gauges connected behind the throttle body and the boost signal coming off the compressor of the turbo, you'll likely see lower then what the spring is rated for due to pressure drop across the intercooler. If boost signal is obtained from between the outlet of the intercooler and throttle body, you'll most likely see either the rated boost, or a little higher since the turbo will work a little harder to make up for pressure drop across the intercooler core.

If you keep your foot out of the throttle, gas mileage really isnt effected all that much if any. Our shop 2011 twin turbo 5.0 car still gets almost 28-29mpg on the highway with cruise on at about 70.
Very good, we already have guys calling and pricing everything out to order. So I was assuming the word was traveling
No my truck has never been on the dyno but typically on a system like this with the 76mm, it will be around 600rwhp from what we have seen on maybe 13-14psi. This is all an estimate as our specific truck hasnt been on the rollers yet but thats what I would expect.
Ill take more photos later and get them up when I work on it later. The gate location is fine, its going to have great flow, on my truck Im going to vent the gate to atmosphere. we have a few kits that we run twin gates on but this kit you really shouldnt have to unless you were trying to hold say 3-4psi steady. Most guys will be at least 7-8psi and a single 44 will have no issue holding that. We can always add a 2nd gate in the crossover area if you wanted but its going to be overkill
There are a number of things that can cause that, position can be part of the issue. Angle of the pipe to the exhaust flow, backpressure(pre turbo drive pressure), and a few other variables. The positioning on this is good and will have no issue. As mentioned before, if your going very low boost around 3-4psi which I doubt anyone will, we can always add a 2nd gate. We do that on our 4v Mustang turbo system to be able to control and hold boost stead within a 1/10 of a psi down to around 3psi on those cars
