  Got this off a 97 3sfe rav4. I'm going to customize a intake manifold body for it at my work(custom sheet metal shop). this is the starting process should look close to a beams intake when in done. Ill be using 0.100" 5052 aluminum for the body with a machined 0.250" T6 aluminum flange. I will most likely make 2 when i take the intake form my 95 GT off. So I'll have one for sale then. Any thoughts?? This post has been edited by doory100: Oct 6, 2014 - 7:40 PM -------------------- |

I've even seen race engines with unequal length velocity stacks (ITB) to spread out the engine's power peak, assuming the exhaust runners are all equal length. Velocity stacks need to be matched to the cylinder exhaust runner length if the exhaust runners are not all equal length. It's not as simple as it all sounds, you can get quite nit picky technical and doing so usually nets the best power gains.
