??? sorry i miss spelled something

are you that mad about it?

 

im doing it on my singlecam, the plenum im making for the ITB manifold has 4x the volume of stock, the "runners" from the head to the plenum are about 1 inch shorter, they are also a bit larger around, and the combined throttle body surface area is a little more than double from a stock Z6 throttle body.

should get better throttle reponse, more flow, and (relatively) faster air speed b/c of the velocity stacks.

 

the problem with tuning ITBs is that you are removing the intake plenum, so its difficult to get a good MAP sensor reading. hondas rely on the map sensor for fuel delivery and ignition timing.

ITB-Turbo solves that problem by including a plenum that you can attatch the map sensor too.

so its no more difficult to tune than a turbo car.

and tuning ITBs alone are not that hard as long as you have the right ITB manifold (hint, build your own.)
