The dyno doesn't lie.

Text By , Photography by Staff

At 2,400 rpm, the new cam made an additional 3 hp and 5 lb-ft of torque over our previous run before dropping output by about 6 hp and 8 lb-ft of torque throughout the midrange. At 6,400 rpm, the 248/232 combination made as much as 9 additional hp and 12 lb-ft of torque. But purchasing a set of adjustable cam gears to properly degree the camshafts could have recovered some low/mid power loss, we speculate.

As it sits with stock cam gears, this camshaft combination would be an excellent upgrade for turbocharged KA applications that require the engine to rev high to take advantage of top-end power.

CONCLUSION

HP Level +HP TQ Level +TQ
BASELINE 121.6 131.4
AEM INTAKE 125.3 3.7 132.9 1.5
DC SPORTS 4-2-1 CERAMIC HEADER 132.3 7.0 142.5 9.6
'91 240SX (S13) EXHAUST CAMSHAFT 135.6 3.3 136.7 -5.8
FINAL 135.6 14.0 136.7 5.3

Conclusion What began as a baseline dyno run of 121.6 hp and 131.4 lb-ft of torque was revamped with a gain of 14.0 whp and 5.3 lb-ft of torque. Although we lost midrange power and torque with our cam-shaft, we suspect some additional tuning could find gains all around. Still, representing a 10-percent jump in horsepower for under a grand (more than 15 percent factoring in the HKS exhaust), our final horsepower gains were solid for any naturally aspirated inline-four, especially the stump-pulling KA24DE.
