It was a fun van to drive, dangerous, but fun, I managed to get it off the clock at probably 190km/h, and the speedo only goes to 160km/h.
A truck intercooler was cut-down and used, with better results in hot weather and less detonation. Mounted up under the front bumper it was hidden from view as to not show that the van was turbocharged.
A custom grind camshaft was made to increase lift (by about 100 thou) to be more boost friendly.
Interestingly enough, apart from a custom single-plate heavy-duty clutch, the gearbox and differential never failed on me, the only thin g I did was drop a new gearset (3.90:1) in place of the old one (4.90:1) into the stock diff housing for more top-speed friendly gearing. But it would still smoke the rears if you gave it a bit from the lights.
It just had too many problems and eventually it just cried enough.
It used to be an Electrodry carpet cleaning van, until 1991, when the performance bug bit. I left the Electrodry paint scheme on the van instead of painting it, it was a great sleeper van, the looks on some people's faces taking off from the lights, and back in the early 90's it was quite a sight! Even with all the equipment in it, it still got up and went.
With the dual-wheel rear axle it had excellent traction, which was handy with the extra power.
