Made a couple of Radix alterfications
I'm in the process of installing some TEA heads on my truck and decided to take the time to make a few adjustments to my radix.
I port matched the intake runner on the radix lower manifold to the new cylinder head.
Then I added an IAT sensor directly in the air path of one of the intake runners on the manifold. The sensor in its default radix location doesn't respond very quickly to the temp changes
Then I figured, since no one else is getting it done, I went ahead and modified the blower to mount up an 05+ 90mm electric throttle body.

Damn Took you guys long enough Gripp and I had this done two weeks ago and it has been workin OUTSTANDING! You will love the newfound power and performance....
We chose the LS2 Vette TB for the better performance over the LS2 SSR TB. We tested both on the engine dyno and gained about 6 more for a total of 48 crank HP. This should equate to about 25-30 or so at the wheels. This gain is not from the TB alone, but from the timing you are able to add since the IAT's drop and the pumping loss is down. We did not want to post up until some solid testing had been done. Due to the safty factor of messing with a DBW system we thought this would be a great idea. I would like to thank Speartech for the help with the harness, and Scoggin Dickey for the help with development.
All I know is this crew pulls harder than it ever has before.

So you guys swapped in the proper TAC module to work with the TB? That's what speartech and I were talking about before my rods got scared and jumped out of the block... LOL
