Okay guys so we finally have one of our Borg Warner EFR systems out. We  will have the other kits out soon as well. Now this setup is on the  longitude 1.8T on a 2004 Audi A4 Quattro ( so it will work on any  longitude 1.8T). Since we finally have some actual data to share I  figured I would post it up. 
Now, this car is a really cool project. Before the EFR we did a pretty  unique engine build, inspired by our friend Lavi at Unitronic. We raised  the compression to 10:1 and the guys at integrated engineering hooked  us up with their new Tuscan I Beam rods. We spent a great deal of time  balancing and working on the engine. We ported and polished the head,  threw some supertech goods in it and figured we could get a little wild  with boost. We also did water meth as well. As soon as the gods at IE  throw us a bone, we will try out 'dem camz. 
The EFR system uses a equal length tubular manifold designed and built  by us specifically for use with the smaller B1 chassis of EFR turbos.  All geometries cater to the air flow rates of the 6258 and 6758.  We went for a tubular manifold because the packaging of the EFR turbo  allowed us to spend a little more in the manifold department while still  being competitive priced overall, we saw this as a opportunity to make a  more efficient setup. The EFR integrates a wastegate that works  perfectly compared to others and it also integrates a diverter valve.  The savings here are exactly what drove the creation of this manifold. 
Some of the driving impressions. This is the most responsive turbo I  ever had the experience of driving. The boost acceleration is really  awesome, watching the digital guage climb from 2 to 30 psi is pretty  intense. The in gear response makes me think we owe some cast manifold  garrett gt setups owners a refund lol. The turbo is hitting the  advertised air volume as well. The dyno below showes a all out run for  the numbers, and with the engine configuration we are using, we will not  be running it like this all the time. To break 400 on this 10:1 comp  engine we had to run the car cold, raise the timing up, and run 70/30  water meth with a 625cc nozzle. Also the Unitronic tune on the car is  running very well hitting our requested 12.5:1 AFR. We will richen it up  a bit for the road. This was to just see the best we could do with this  setup. The average dyno's put this at about 375 awhp. Keep in mind we  have a mustang dyno which reads a bit lower as well. But knowing our  dyno, i could not be happier with the numbers. It is really amazing to  see a 1.8T engine break 400 whp and still have that kind of power band. 
Now we are finished with our 1.8T longitude, and nearing completion of  out 2.0T longitude. The next up will be the 1.8T and 2.0T transverse  systems. Soon we will have info regarding a more practical build,  meaning drop in 19mm IE rods, and supertech valve train with the smaller  6258. All of the info so far is from the larger 6758. I think this will be a really cool package for the guys that are looking for the most power without sacrificing response. 
Also check out our face book, there is a video on it demonstrating the  rate in which the boost climbs. That was a run in simulation mode during  tuning with only 27psi of boost.  
On to the pics
