oh also, what did it run in the 1/4 with both turbos if you don't mind me asking?

It made 709whp on our 1100SE AWD Mustang dyno. We choose the BW basically because it spools WAYYYY earlier than the FP. The power per psi is better, and the main reason, the hotside on the FP is way to big IMO. Our FP 3794 didn't light up until 6200rpm, but we have a T4 1.15. We are running the Ultimate Racing Twin scroll kit with all the things wrapped, with giant kelford cams.

We never ran the FP3794 here in America. He ran it in Mexico but they don't record times like we do. We had this turbo on the car for the Texas Mile in October and his trap in the 1/2 mile was 167mph. We had major issues with the AP preventing us from breaking into the 200's with this car, so we have upgraded to a Cosworth standalone now. (Our other shop STi broke 201mph, making him the fastest STi in the standing mile).
We just got the BW turbo on and took it to the track for the first time a few days ago. The first day we ran a 10.8, but only got one pass in before the event got rained out. So we rented out the track on Monday, and ran a 10.6 (remember first time running this set-up so he was trying to get a feel for everything and work on his reaction time and 60ft). He trapped a 140.94mph in the 1/4.
On our last pass of the day, he finally got the launch down. Was a perfect launch and he snapped the rear diff pinion right in half. It's crazy! We are still on the stock 2011 STi transmission without any problems, but are now upgrading to a dogbox with PPG gears and an upgraded Albins rear diff pinion. We will be back at the track for IFO on Dec. 9th.
