The B20 might want a bump centered at about 4-4.2k rpms. I had to switch dynos, because the guys at the other dyno were kinda jerks. The new place is DynoSpot Racing. I paid regular price, so no hook-ups here. They treated me fair and I will be back.
Red curve is from the new dyno session, the blue curve from the old session.
Not quite the gains I expected to see. Next time I will probably switch out the exhaust and cat to get a better picture. Also, the B20B cams are obviously not high rpm cams, so adding the header at this stage is premature. The header won't shine until I add the Crower cams, and raise the power peak rpms. Tuning the Fuel and Timing with the Shogun Played with the Shogun for quite awhile, adding and subtracting fuel until the power went down.
