Up top, all brackets and tubing are reinstalled and the power steering reservoir is refilled. With the Vortech supercharger system in place, it's hard to catch a peek at the headers, but the shimmer of aluminum-ceramic coating can be seen from certain angles. | 
Back on the Dynojet 248 at East Coast Supercharging in Cream Ridge, N. J., we had our fingers crossed for a good power increase--but ended up getting more than we'd planned for! Plus, ECS didn't have to do any tuning on the car whatsoever; they left the program exactly the same as it had been before the headers were installed. Sounds strange, but different cars behave differently after headers are installed, and ours just didn't happen to need it. | 
The results--with the same rock-steady 11.6:1 air-fuel ratio as before--were 521 rwhp and 460 lb-ft. This is a staggering 50 rwhp gain with just the SLP headers! This number was also achieved with the torque converter unlocked, so really figure about 551 at the wheels, which translates to about 688 at the flywheel. All on 93-octane ExxonMobil Jurassic juice to boot! |
