Car Show Entry
This vehicle is very unusual and is frankly an on-going project that has evolved over seven (7) years of constant change. Although there are many of the core components from numerous Subaru vendors. We have had to modify many of them in order to allow us to develop our engine to our specs. For example, the heads and the cams that are placed on our new engine are unlike any heads or cams (to our knowledge) in the USA. We calculated that with these new components we might approach a reliable 1000 + whp on only 30 to 40 ft. lbs of boost, which will be a shock to the Subaru community. As normally at that level of power usually requires between 45 to 70 lbs of boost, or a combination of extreme boost and / or Nitrous. Our testing indicates that we won't require either of those two extremes to achieve our power goals. But when your a group like ours consisting solely of mechanical and electrical engineers you end up with this project, which is a never-ending project and experiment. We think your crowd at Subiefest might get a kick out of the vehicle!
Event: Dyno-11-2022 Grandpa’s Toy
Location: Rocklin CA Component & Parts List
Ambient Temp: ?
Elevation: 146 ft
Maximum Power=MAP #1=927whp at 6100rpm and 832 ft lbs. of torque@ 5500rpm, For show purposes and testing we keep the power quite low. As we have under MAP #2 achieved the low 700's primarily to test various components and metal treatments and to make the car more durable and drivable at road tracks like Willow Springs.
