A good day at the dyno...
Had a good day at the dyno with my '93. Questions frequently come up here about what various mods can do for our motors. Thought I'd post a comparison of my 2009 dyno results and today's. Mods as of '09 included siamesed plenum and injector housings, 63 mm throttle body, and B&B exhaust (stock manifolds and cats). Since then the heads have been ported, cams have been swapped, and SW headers (no cats) and mufflers have been added. Picked up 80 RWHP and 33 ft. lbs. torque. Using a 15% driveline loss, HP at the crank is now 558. Pretty amazing for a stock short block. HP/liter is almost as much as a supercharged LS9! Gotta love these motors!
