Why do you talk down to every body that isn't swinging on wade nuts next to you ?

And this is the bs that keeps the actual intelligent Duramax guys from posting all the time.
This same combo is already out there and has made the power. Now we just need to get the trans to hold. Brian just got done building me a new trans, the same one H&S has gone mid 8's with. I went 9.2 with the old motor trans combo so we are setting the bar higher this time around.
Thanks for all the complements guys. My goal is to have it running early this week and and put a few miles on it then test Friday night with Mark.
Made it to Indy to race today. Converter took a shit first pass but I got some good data logs before it went out. I think I need to add a wastegate to the system. Atmosphere chargers put out 34psi, total boost was 120psi and drive pressure was 96psi. I need to add a gate to the exh housing of the high press charger or add one gate to each manifold. I know nothing about gates so does anyone have a recommendation of what size and brand?
Thanks

Use a quality brand Brett. I b like the Turbo Smart that I am running now. I went big on the high pressure gate at 60 mm. Most people use smaller gates and sometimes run into problems with not having enough gate. It sounds like you atmospheres are just following more than the high pressure can provide for air. Maybe try a bigger turbine as 92 or 96 on the high pressure. Did you get to make a full pass before the convertor let go?

Shane, I may give you a call to talk to you a little more about it. I'm going to talk it over with Mark and see what he wants to do.
I did not get a full pass in. I think I ran a 10.6 @ 88 this new motor is so awesome. I ran on my tune 3 so there is a lot left in it.

Here is a short video of the truck running at Indy. Once again HSPDiesel.com does some amazing fab work. I could not have asked for a nicer better fitting kit then what they made. Were going to put this Danville built motor to the test!

Ready to see wfat a full pass does for you

With those numbers, I'm not sure I would change anything. You have a 3.3:1 pressure ratio on the atmosphere turbos and 2.7:1 on the high pressure turbo, and drive to boost ratio is .8:1. I don't see what benefit you would get from a gate.
By the way, it was nice to meet you this weekend and to see your truck in person. I wish I had more time to visit and look everything over better.
