2022 Ford 7.3L Godzilla Dyno Results
This development is for those wanting relatively minor upgrades. Later testing will provide results for a CNC porting of the cylinder heads for both intake and exhaust ports which also qualifies the combustion chamber and allows for use of the standard .75 reach gasketed seat spark plugs. We will also evaluate camshafts we will offer, one intended for use with stock bottom end, the future testing will provide camshaft evaluations for build bottom end.
Before we start we want to talk about our baseline of a stock engine that's only modifications are:
Our baseline was 507 HP for the Ford 7.3L, this is how we get to the Advertised Ford Number:
Results BTR Truck Norris Camshaft, BTR Intake on a stock Godzilla engine.
We tested a stock Ford 7.3L Godzilla with very few modifications. This engine was a completely stock Long block with just a camshaft change (did not even have a cylinder head off). The intent of this evaluation is to provide the potential of the Godzilla engine with minimum changes. All testing with spark and camshaft position set to best output with no audible detonation.
Results Summary:
Before we start we want to talk about our baseline of a stock engine that's only modifications are:
- Use of Ultimate headers that are for a FoxBody Mustang as opposed to the stock exhaust manifolds.
- Use of electric water pump.
- Performance is corrected to STP (Standard Temperature and Pressure) which the common correction factor for engine builders as opposed to SAE J1349 Correction Factor. SAE J1349 which is the Procedure Manufacture's use to rate their engines. This procedure has a full air induction system and exhaust backpressure representing the full vehicle exhaust or uses the vehicle exhaust system in the test, along with the factory FEAD (Front End Accessory Drive). We have non of these losses, and have also used the OBR control system to optimize the calibration with pump premium fuel. Why these may seem like fairly small changes, they do add up.
Our baseline was 507 HP for the Ford 7.3L, this is how we get to the Advertised Ford Number:
- 519 HP WPE Baseline
- 21 HP Impact of Air Density difference between SAE J1349 and STP (4%)
- 15 HP Impact of no FEAD nor water pump (estimate)
- 46 HP Impact of no induction (everything upstream of throttle body) and exhaust system (estimated 9%)
- 8 HP Impact of 93 Octane fuel (Estimated 1.5%)
