2012 mustang Hellion Twin Turbo Results 941 Rwhp 915 Rwtq This is my personal car, 2012 Mustang GT, which we built in house. This is my first Mustang, as we are a LSX build shop primarily.
We initially developed a Single turbo system on this car late last year using a Comp 8079 turbo. We quickly found out that these cars have very weak valve springs and backpressure being developed caused valve float anywhere past 8 psi of boost. This was very disappointing to say the least.... So we scraped the whole single turbo system, built the motor with Manley rods and pistons and had a custom Napier Cut 2nd ring made, put together a fuel system in house, E85 fuel, and installed Hellion Twin turbo system.
The kit was not the easiest of installs but damn was it worth it. When you pop the hood everyones jaws drop. The engine with the top mount turbos is menacing. Myself and my employes were all very impressed with the fit and finish of this kit. Every time we thought something wouldn't fit, it cleared perfectly. The R&D that went into this kit is spot on. We initally didn't want to push the new engine to hard but that quickly went out the door. At 15psi we were making mid 800's and everything seemed to be working so well I couldn't not turn up the boost. The result as of right now is 941.4whp and 915.5wtq at 18.8psi and a car that runs around the street with the manners of a stock Mustang, as long as you keep your foot out of it.
I have owned some pretty quick street cars with 3 full weight 6 speed street cars running 10.1-10.4 in the quarter. This car makes those cars look and feel tame. I will be doing a few more modifications to the suspension and chasis to hook all the power, once that is accomplished I have no doubt that the boost will once again go up.

After getting spanked by this TT beast all last week, I finally got a chance to drive it Sunday. When it comes on boost, it's the proverbial freight train. The car flat hauls ***.
I'm pretty sure my Roush set up will be for sale sooner than later.......
