Dyno Results – Stage 3 Ultra Street
This project is intended to determine the limits of capability on the 2020 Ford 7.3L for the Stock Block, Heads and Crankshaft. I am confident that the cylinder head flow (with VED/WPE CNC Stage 3 porting) and valvetrain stability (with the mechanical roller camshaft and Shaft Mounted rocker system) will be able to make competitive power 1600+, but we need to demonstrate that it cam make this power reliability enough for competition.
This page will provide project status from dyno development and learnings to in vehicle performance.

As of December 1, 2020 we have completed our initial Dyno testing naturally aspirated and are working on a few modifications based in issues identified in the initial development.
Components in Engine:
Block: Stock block with the following upgrades. Roller cam bearings at stock size (60 mm), block partially filled with hard-block.
Crankshaft: Stock, with dual keyways added and re-balanced for MGP Connecting Rods and Wisco Pistons.
Pistons: Wiseco custom 12.5:1.
Connecting Rods: Custom aluminum with stock length.
Cylinder Heads: Stock Castings, CNC by VED to WPE/VED Stage 3 specifications. Heads are also machined for a shaft mounted rocker system.
Valves: Victory Titanium; 2.25 Intake, 1.70 Exhaust, using PAC 1357 Valve Springs.
Camshaft: Tool steel camshaft by Militia Products (Charlie Westcott Jr.) in Parma Michigan, also use his VCT lock out system.
Rocker System: VED (Visner Engine Development) designed shaft mounted rocker system, available with both aluminum or steel rocker arms.
Push Rods: Trend custom, 1/2 inch diameter.
Induction: Designed for Whipple 3.0L supercharger, with N/A testing done with VED billet aluminum.
Oil Pan: We plan to run our Dailey engineering dry sump pan, but results to date are using the Stock Ford pan and oil pump with no modifications.
Fuel System: Stock Fuel rail and Injectors for the NA testing to date with fuel pressure set to 90 PSI, Aeromotive A1000 fuel pump NA. Moving to the Aeromotive new brushless 10 GPM with Supercharger also changing to Whipple Fuel rails and Billet Atomizer fuel injectors.
Naturally Aspirated Results:
Initial testing was promising making just under 800 HP and 560 Ft-Lbs. We did see an issue with our initial design of the shaft mounted rocker arm fasteners, which we are making a design change to improve clamping force. We expect to have these issues addressed and look to be back on the dyno in late December 2020 or early January 2021.
