Getting Greedy - Getting Closer to Our Goals
|
With the engine looking and sounding as awesome as ever we headed over to Crazy Horse Racing in South Amboy, N.J., for a little fun on the chassis dyno. Our stock numbers (with timing and air filter improvements) came in at 197.2 hp and 256.6 lbs.-ft. torque at the wheels. Our first pull with the new engine combo saw a jump to 238.4 hp and 273.4 lbs.-ft. torque--an improvement of 41.2 hp and 16.8 lbs.-ft. torque at the wheels. As mentioned, we felt that the stock 19-lb. fuel injectors could possibly be too small for the new engine combination but the air/fuel monitor on the dyno told us otherwise. We were actually way rich below 3000 rpm. After removing only 3 psi of fuel pressure from our BBK regulator, we picked up 20 hp and 25 lbs.-ft. torque at 2800 rpm. The peak power numbers stayed the same but we gained a ton of hp under the 3000-rpm range. Our air/fuel readout showed a way-rich 7:1 ratio (14.7:1 being ideal) but after the adjustment, it shot up to 12:1--still a bit rich but a much better improvement. It looks like the stock 19-lb. injectors will work just fine for now. View Related Article
