704HP 3V '06 Mustang Kenne Bell 2.6H vs. 2.6

The new Kenne Bell 2.6H made 704HP/ 734 ft/lbs on the ST Motorsports dyno. The car is a test mule for a big upcoming feature in 5.0 Mustang magazine.
The objective was to determine, through extensive testing, the limits of the fuel pump, injectors, throttle body, meter, inlet system, clutch, transmissions(manual and automatic) and the stock rods and pistons(they gave up at 565hp). A Sean Hyland short block assembly with forged rods and pistons was installed to handle the power to 800 hp - or higher - so testing could continue.
Boost is being evaluated from 9-23 psi inlcuding the new Kenne Bell 10 psi kit with both the Kenne Bell standard 2.6 (9-14 psi) and the latest 2.6 H (15-23 psi). In a direct replacement back to back test with the same pulley, the new 2.6H with it's unique High Internal Pressure Ratio developed an additional 31 HP (652 vs. 621) with no other change. The boost was IDENTICAL for both superchargers. The 31 HP difference was the result of the lower power consumption/parasitic loss of the 2.6H at the higher boost levels. Boost was 19 psi for both the 2.6 and 2.6H. The only HP mod to the engine was a 60mm Accufab throttle body (+25 HP at 565 HP level). Upgrading the stock 90mm meter to the new Kenne Bell HiFlo Oval 1500 meter pushed the HP to 704 RWHP - a 434 HP increase over the stock Mustangs 270 RWHP. With a larger throttle body, some head work and cams, the goal is 800 with the 2.6H. This was basically a 100% stock Mustang GT engine with one power adder. Heads, cams, exhaust, exhaust manifold, compression ratio etc. were stock. The KB BOOST-A-PUMP, larger injectors, Accufab throttle body, KB HiFlo Oval 1500 meter system and custom tune were the only mods except for the Sean Hyland built short block.
To accurately evaluate the difference products and modifications, all runs were made with the same timing (24degrees) and AFR and absolutely never more than "one change at a time".
Check our website for the upcoming "'05-'06 Mustang GT. 4.6 3V Tech Tips" for updates on the above mentioned test and much more. There will even be manual vs. automatic trans (lock up and non lock up) converter test.
