EXPERT DYNO TECH
Based in Paeroa, BRM Dyno is a specialist tuning facility owned by
Brett Roberts. We had a chat with him about how it all started.
I
started back in 2000, working out of my
building in Kaka St, Otahuhu. I was having
a bit of frustration with the tuning of bikes
and quads that I was doing at the time. We were
basically ripping up and down the road (I had a
very quiet back street) trying to figure out if the
changes we made felt better or not. Back then I
was doing a lot of Quarter Midgets (XR200
engines) and they were even harder to test.
We were doing a lot of work for Robert
(Cheese) and Shane Van Gisbergen at the time,
Shane was racing anything thing that he could
and Robert, his petrolhead father, wanted
everything to be the fastest (that’s how Cheese
is). It was his idea to buy a dyno. It sounded like
a good idea, so I priced up a few new ones... and
I can tell you there were a few frosty nights at
home when I told my wife that a dyno would
cost around $70,000.
So, one day Cheese rocked in with an advert
page he had liberated from an Auto Trader
while at a gas station. It was for a secondhand
Dynojet 150 that a guy had under his house on
Auckland’s North Shore. A couple of days later I
was the owner, and $19,000 lighter. I didn’t know
anything about running a dyno, but we got it
going that week and had a play with a few bikes.
PROVEN GAINS
In those days it was a DOS operating system,
rather than a mouse/Windows operating
system, and it had capability to measure the
air/fuel ratio. We taught ourselves to read the
graphs, and then, with a bit of trial and error,
