Accord Euro Dyno Results

[Crapdaz]

from the dyno day
Cranial - CL9..............110.6kW, i think he was stock, not sure as id already left(b4 he came).

Crapdaz - CL9.............. 113.6kw similar mods to me

tahts the other euros that went that day

i ran like crap wonder if it'll make a difference if i add a feedpipe to the blower.

Won't be representative of the car as it is driven on the road.

yeh true, on the road you get more direct wind to where my piping is.
ah wells post my smudged results when i get home.

And I'll post mine from when I ran earlier in the year.

i didn't get torque though for one of my axis, i think it's air/fuel ratio.

Same for me. Don't need the torque curve, I can calculate that from the power curve. The A/F ratio gives good information as to how much more power you can squeeze out.

anyhow what is the best air/fuel ratio?
or how does it work? and do you know from the top of your head what stock AF is?

14.7:1 is stoichiometric. My opinion is that you should max at 13.5:1 at full throttle for power unless you are doing a racing car where you will be checking pistons after every few races. When cruising, then the A/F ratio goes closer to 14.7:1. Other engines like in the Jazz can run higher than 14.7:1 when cruising. I think. I have run on 2 different dynos, car was the same both times. One returned 10.5:1, while the other said 12.5:1 with a dip to 11.8:1 around 5000-6000rpm. So I can't tell which is the proper A/F that the stock car is meant to have!

[Cranial]

Yes mine was stock other than my gearbox mods. I have no engine I/H/E mods at all. How how was the outside temperature like when you did your runs Crapdaz? It was hot as hell with 36 degree temps when I did mine. Not too good for dyno readings I dont think (I wonder what it would read on a cold winters day?). I'll post my sheet soon as well. On my sheet, I only have A/F ratio as well, and the line on the graph has a sharp drop halfway on the graph as speed increased for some reason.

Yeah around the same as you my face was burnt afterwards.
around 36deg not far from you.

My power was pretty linear up, no sharp drops.

Btw does gearbox mods and clutch + flywheel make a different with power output?

You'll probably see the same drop on our charts too. Here's mine:

Flywheel doesn't increase the peak power, but it should increase the torque and hence power at low and middle RPM.
