Default 253.2 HP @ 5500 RPM / 264.4 LBS TQ @ 4750 RPM @ 11.7 Lbs of boost

253.2 HP @ 5500 RPM / 264.4 LBS TQ @ 4750 RPM @ 11.7 Lbs of boost

First I would like to thank Ben Strader with EFI University (www.efi101.com).

I was in the process of building a new engine/computer combo for my car, and decided to enroll in the efi101 class. I needed the help for programming and tuning on the aftermarket computers. After the efi101 class was over, we put my old engine/computer combo on the dyno to see what she would do. The engine could not even make a pull because of the computer system it currently was running had a problem. Myself, and the rest of the class started talking with Ben about an advanced course. We talked about using my car with my old engine and a new Autronic computer.
Yesterday, (Oct. 2), was the advanced class and my car was on the dyno all day long. 8 students (including myself) drove the car building a map. We didnít have a map to start with, so we built a map and did some pulls.
I must say that after leaving both of these classes, I have learned a lot about:
Tuning (all aspects)
Driving on a dyno
How to operate a dyno
Different types of dynos

Now about the car:
This engine has over 4 years of abuse
Subaru engine EJ25 stock block (open deck).
JE pistons
Pauter Rods
ARP head studs
Iíve done some porting to the heads (a lot of chamber work and some port work)
Stock cams, springs, etc.
Autronic computer
MSD ignition
T3/TO4E Turbo
RC 750cc injectors

After running the car all day we made a pull. This was performed on a Mustang dyno At W.O.T. in Riverside, CA.
253.2 HP @ 5500 RPM / 264.4 LBS TQ @ 4750 RPM all done with 11.7 Lbs of boost.

We started to turn the boost up, but the boost controller was not cooperating. We had to make several pulls just to get the boost to come up 1 lb. The air intake was getting too hot. The dyno shop (W.O.T) itself was pushing 90 degrees. The boost controller was only working correctly on a lower boost setting. Iíll keep you posted on future pulls.

Thanks to EFI University, W.O.T. and the advanced class

nice #'s. What compression ratio are the JE pistons you are using? I assume 8.5:1.

Isn't WOT a 2wd dyno? How did you dyno your AWD car there?
