Hi Folks

finally I went to the dyno to see if my butt dyno is right


Here you have the curve before the Supercharger with Aftercooler, HP are measure at the flywheel.

Love the look of the install in that pic.

What does your "butt dyno" tell you? (this would make more sense to me than a graph)

That looks like an extra 100 or so bhp. Very nice. How does she feel on the road?

NA flywheel HP seems low at 214BHP.
Supercharged looks good though.

Nice - very tempting with the current

What are the different colours lines on the graph mean? I presume the left axis is bhp. And what does at the flywheel mean?

Chris Type R

left axis, hp
right axis, nm
bottom axis, rpm
blue, hp
red, torque
green,

Green mean power loss due to the traction...

at the end of the RPM range (7500- 9000) we had some problems becasue the car started to slippered, So we wet the tire with sugar&water and I sat on the trunk!!!!

"butt dyno" says wooooooooooooow!!!



The car is easy to drive, like haveing a 6 clynder engine.


people at the dyno told that the car is runnig very lean 14,7:1 A/F ratio:

1. I checked the plugs and they were a bit dark = Rich mixture

2. I call Comptech and told them the they measure the Co2 emission using a sonda on one tialpipe.......... Joe told me to buy a wideband and measure the A/F ratio, becuase the way that the measure is not very accurate:
2.1 I have two tial pipe
2.2 I sould see the mix before cat to get the right measure.



I will get he wideband by the end of this week, I will keep you posted.
