Very nice turbo Pat, the GT3071 is definitely a great charger.

Awesome work pat. I'd imagine it would be quite aggressive with the .64 rear housing.

Yes the housing is the pick off the bunch, response is similar to the steel wheel CT26. I have tried the larger one in the past and didnt really like the response, although for a circuit car the larger housing may be better suited as you are often in the higher RPM range. Dyno plot below, note there is more tuning required, this was tuned without a knock box or RPM signal so on the conservative side
 

Finished engine bay
 

Wow pat, that engine bay is looking really nice now... clean & all!

Very nice. Looks like you've used lots of parts from your old red car?

Yes Rob its all the red car bits minus the engine, I have some plans for that engine a bit later on  Responsible recycling!

Looks pretty serious Pat

Very Impressive!

Did you fit A/C for the drive to wake field next year?

A/C is for pussies Eric, alternators are far more important!
 
I have been tuning the 3SGTE for a number of years now in various configurations, the graph below shows the results. I will generate a similar graph for torque when I convert the data.
