New Dyno Result @ Torque Performance

[insanekiwi]

Stage 1, REVO ECU.
This is as you can see, in Auckland warm weather, no fan over intercooler, being tested as a first roller on dyno, and small fan over radiator only.

My first dyno was 135.6kw then second falls right down to 130kw. I believe, at decent temperature with large fan over intercooler, and not much rolling on dyno prior, will net me 140kw.

I am waiting for Stage 2 REVO in May.

Nice!

Congratulations for the achievement.

Thanks... also what difference does it make when you put bigger and heavier wheels? if the diameter is exactly the same.

heavier rims resist momentum.

Theoretically, you would loose a bot of torque.

The biggest issue seems to be where the weight is, if the weight is close to the hub, there is less resistance. If the weight is futher out (eg low profile wheels) then some of the torque is lost trying to spin the weight.

I've heard it compared as a cocktail umbrella compared to a beach umbrella.

Dyno operator errors would be bigger than the difference wheels would make on the dyno.

I had lightweight wheels and thought the dyno was under quoting but not sure, don't think it affects it as much as you think.

A dyno is measuring a wheel which is already moving fast. I think it would be most noticable at low speed (eg, coming away from lights)
