tooter's next manifold adventure...

Sorry, I don't have the time or the resources.

This is just a hobby I do on the side in my free time off of work. Dyno time gets really expensive when your car is on the machine and you're trying to swap out parts. Adding the cost for new CNC programming would make it unpractical to make a bunch of different sizes. Anyways you can simply extrapolate the difference as a one inch spacer would make half the torque as a two inch.

I picked 2 inches because that is the thickest spacer which will work without interfering with the engine peripherals like the oil dipstick tube. The two inch simply drops into place like it belongs there.



Other intake manifold spacers sold like this one for a Toyota Tacoma V6 are usually only a half inch thick...



...while the tooter I.V is like stacking up FOUR of them.
