Since I'll e doing my own pump I started with the ALDA .
Using a valve spring from an old head on a 40 mm cylinder gives proportional
to pressure travel starting from almost 0 bar . It's linear to 5-6 bar . Haven't measured the travel mm/bar yet .
To my mind it should keep smoking very low as the pressure rises .
And the slots allow for some fine tuning on how fueling picks up as boost is applied .
Here's a photo of the intake side
And the exhaust manifold
Still waiting on the flanges and aluminium parts from the laser guys . Will have some practice TIG welding aluminium .
