Many many moons ago, in the dim dark distant past, I wrote an article for the
club magazine, where I visited Torque Performance (then in New Lynn), and had
my car dynoed.
My car , which at the time, had a Jackson Racing Header and cat-back exhaust,
and a Greddy foam cone-intake filter recorded 90 HP. At the same time, we
also measured Chic's car. His engine was obviously not running its best,
oil-smoke billowing out of it, and measured 81 HP.
US Dynojet dynos typically show a stock 1.6 as having 90 odd HP, and cars with
similar mods to my own as about 7 to 10 more... so considering that Chics car
was sick, the Torque Performance dyno probably reads about 5-10 HP low.
Since that time, Chic's got a new engine, and I've re-built the one Chic had,
including shaving the head, port&polished, big cams, Link ECU...
Don't currently have a reading for it, but I hope to get one next weekend. On
Sat 3rd of Aug, NZ Performance Car mag are having a Dyno day, where you can
get your car on the rollers and a power print-out for $50 (half the normal
fee).
I'm expecting/hoping for 120+ HP.
Not sure why your dyno reading is so low? BTW, 52kw is 69HP, but I'm guessing
you were looking for more than 2 extra?
I'd discuss it with the operator... Ultimately, as long as it gives
consistent readings, you can use it to see percentage improvements, but I'd
still see if they acknowledge that its calibrated differently, is known to
give low readings, or any other logical explanation. Also, what were the
torque figures?
For some reason, the Torque Performance dyno gives HP numbers that look
reasonable, but the torque figures are actually exactly double what is
considered the "normal" HP/Torque relationship. I will be discussing this
with Robin (the owner) at torque performance next weekend.
BTW, as far as I understand, every-one is welcome to come along and have a go,
or just watch... there'll probably be some impressive cars there, if you're
interested...

Red '90. Many n/a mods and Link ECU
