|Salvaged the turbocharger from an MG Metro Turbo.||
Turbo shaft with impeller and turbine.
|Noticed that the design of the impeller casing (cold side) has a large flat area outside of the impeller, presumably to make use of the energy in the air to create a larger pressure change.||
Machined down the casing to fit an Astroflight Cobalt 40 motor. Luckily, both the Astroflight and
the impeller use a 1/4" shaft. Just used a 4mm grub screw to secure
the impeller to the shaft.
|Dominic performs initial tests on the sucker and seals... Both of us were able to hang from this test rig.|
|An area on the underside of KillerHurtz was sealed with flexible door-sealing strips. You can see the turbo mounted at the back (right hand) edge. We though about including the wheels in the low-pressure area, but it would have been a big job keeping it all airtight.||
One of Astroflight's excellent little power-meters showing the current drawn by the motor. We were planning to have a two-stage switch to conserve power.
