0405htp Drag 29 Z

From a 290.4/297.6 baseline, the SLP exhaust brought the dyno numbers up 6.3 ponies to 296.7 horses and 297.5 lb.-ft. The 0.1 lb.-ft. peak loss is deceptive because the car gained as much as 5 lb.-ft. or more in the upper rpm range. LS1Speed's intake gave an additional 7.6 ponies and 3.3 lb.-ft., with 304.3 horses and 300.8 lb.-ft. resulting. SLP's tuning yielded what can only be called an awesome increase in power and torque throughout all rpm ranges, adding 23 horses and 26.8 lb.-ft., for a grand total of 327.3 horses and 327.6 lb.-ft. showing at the rollers.
