tooter's manifold adventure...

having a crank damper has nothing to do with internal balance. The crank actually deflects...especially at higher RPMs & high power outputs. doesnt matter if is a old domestic motor or a k20a in a honda.

without typing out a huge thing about this subject ( I used to work for ATI Racing years ago, who makes the best crank dampers) Most lower output economy motors dont really feature a real crank damper, but rather an accessory damper.

4/20 i made good power (107/104) with a weapon*r header & my own full 2" mandrel-bent exhaust which seems to be a great match for our motor. 2.25" would most likely shift the power band upwards, but with minimal gain. I would test on mine, but Im working on a turbo kit now.

Now that's a damper...

Yeah, I have a 2.25" (crush bent) resonator back on my sedan, and it pushed the torque up past 3,500 rpm, where I'm rarely ever at. With how my car is (that exhaust, K&N sri, NST CR-Lite crank pulley, and my heavy rim/tire combo), it really feels like I have turbo lag up until I pass that point. I want my torque back down lower
