Now for the backround:

This is a 2011 GT
Manual
Barton Shifter Bracket
3.31 Gear
Stock Clutch
Stock Shifter

Hellion Twin Turbo (installed himself)
BBR TUNED
80LB Injectors
BBR Off Road X Pipe
Free flowing Flowtubes & Muffler

(thanks Mike)

Now today (11-5-12) Alex brought this beautiful machine over to us for a finalizing dynotune. Now as requested, the tune was VERY mild and beyond safe. We kept the stock boost levels (5.5psi) and timing at 16degrees. Which with the results.... I am very happy. Now people will look at this and say mine made more for less money, ect ect ect.... The point of this was on ONLY 5.5psi with low timing on a 11.3 A/F with 80degree for IAT and 184 ECT (temp during pull in shop was 87degrees with low humidity) this thing made....... well Ill explain some more beforehand.

I give Alex a lot of credit for an outstanding job on the installation of this turbo system. With his time, he installed it correctly and in his words "a great learning experience" We as well as Hellion were their for everything we could to help. Gave him my cell # if he had any concerns on weekends or after hours questions.



Funny how we were strapping the car on the dyno, Alex was getting pretty excited just watching the car. It was time to test the waters.



(The reason for no bumper is it would not fit on the trailer coming here)

At first, Chris tuned the part throttle and nailed the drive-ability down. Didn't take to long but its always nice to fine tweak tunes.



After everything was dialed in, time to make a full pull.


Here are the results. Again... this was on 5.5psi with low timing



Now before someone does ask, the SAE #s were only off by 4hp so it is something you will not notice


We are all excited about these numbers on low boost. Alex hasn't stopped smiling and is a little kid in a candy store with it and we don't blame him.

Now it's time to enjoy the car and have some fun

:beer:

Those are really good numbers for only 5.5 psi! I can't wait to see the videos and track times it puts up...

Very nice hp numbers on 5.5psi. TQ is pretty low at the low rpm's I guess due to the 5.5psi? Turbos are running on the low side of efficiency?

so there is less than 1% difference in STD to SAE??? I don't think so! but any way the graph looks ok not the cleanest but for 5.5 psi.. And that torque is falling very fast and hard? are they out of effciency already? I guess I just expected better results with a cleaner graph and in SAE corrected numbers . But to the owner enjoy!
