EGT's aren't directly related to coolant temp that I know of but it does help keeping engine bay temps down quite a bit.
I have Precision 46mm gates on it. They are CO2 controlled dome pressure provided by the standalone ECU.

Nice results so far.
What A/R ratio did you go with on the T4 divided housing?
What are the rest of the dimensions for the Garrett 4" core? How does it seem to be doing on IAT temps?

I guess I kind of meant more under hood temps but ether way cool ****, brother!

Incredible build! I love it! I started my TT 6870 build over 2 years ago and have been dying to see what they'll do. Business has gotten in the way. I hope to get back on it within the next couple of months. This certainly helps inspire me to get it back on the road. Thanks for sharing!

I went with .86 divided T4 housing. So far it seems to work well.

Here are a couple of teaser Pictures!
I've had the car on the dyno a couple times and I am having traction issues recording above 1500whp. The dyno recorded 1528whp (28lbs of boost) at 5200rpm before I let out because of rubber flying. You can see in the below graph it fried the tires instantly.
It totally spun the tires and put rubber on my windows, walls and cabinets!
Even on the below graph at 1470hp (25lbs of boost) graph I could feel the tires Shake and it feels like a jack hammer is in the floor of the car! Not a bad problem to have really. LOL
Hope to order some VHT to spray the rollers sometime in the next couple weeks. Will update the results after the Indiana WGF Event.

That is a little complicated. lol. I was using the dyno gear ratio to calculate RPM which works great unless you have wheel spin. In this case it came up around 400-500 rpm short each time and around 15mph short. I will repost in RPM when I get the traction issues cleared up.

We just finished a 427 LSX with twin 7675s, in a standard .96 t4, and its lit by 3800/4000. Minimal spool. I busted nick yoskins ***** a few years ago, because on paper, it should be laggy. However, it's not.
@16psi, it made 1220/1100, and carries to 7k.
Build looks good! Can't wait to see it completed!

Yeah my top mount 76rs are not laggy at all.
BTW BAM BAM is for sale. I turned into a roadrace track rat! I never drive BAM BAM. Nickyoskin@gmail.com if anyone is interested...sorry for HIJACK
