I had the Oval tuned the other day on a dyno at Tunesmith
Engine specifications
1916. Stock heads 110 Engle cam (not ideal for a supercharged motor) and 1.25 rockers, Vintage speed exhaust. 4 LS coils, Dubshop crankangle sensor and CB cam position sensor. Haltech Nexus 2 ecu. 485cc injectors with a 5th injector before the supercharger and drive by wire.
SC12 supercharger with custom pulleys.
Best 98 RON run was 98.5 kW or 132 hp at 5550 rpm and 80% throttle.
We then swapped to E85 and did a few power runs but a gasket leak at the inlet manifold prevented anymore power runs, but it still made 108kW or 145.6 hp at the wheels on 90% throttle.
The best thing about the drive by wire is that the throttle can be used to limit boost. The drive by wire is also used as a rev limiter, it rolls the throttle off near redline before a fuel cut
I'm using Mexican efi manifolds that were modified by Ben Wallker from Third Strike Fabrications
