Probably need a video your your confusing statement of the tach.Turbo Habanero;1917491 said:Anyone ever have issue's with there tachometer keeping up with engine rpms?
Ever since the swap the tach cant keep up with the rpm drop and climb.
But might be cause 1jzs are rev happy and now it has the light weight internals in it.

Or am I having a brain fart, kind of like how a head wind can make a plane fly backwards but not fall from the sky.
One water pump spins clock wise, the other spins counter clockwise has nothing to do with the fan blade? If the fan blade was left hand pitch instead if right hand it would push air into the radiator instead of pulling it out.
