Dyno Results

[Chapel]

Now, my A/F is high (15:1 in the top end at WOT)
But some of the other guys there were getting way off readings (lean) too
This is a tail pipe gas spectroanalyzer, which can also be thrown off by a clogged cat.

I figure I can get another 2whp out of it with the Supersprint installed.

Overall, Im very pleased when compared to last year's results (blue)

Does anyone else have any dyno readings with A/F on them with a JimC chip and without so I can compare the two?

Even if the A/F was off on the dyno, I would like to begin tackling what could be a possible problem. I figure I'll start at the fuel filter and work my way to the injectors

Not a bad outcome for a 200k + engine.

to say the least
175bhp peak corrected @ 15%
someone asked me if it was a turbo because of the big ramp at 3500. He's not used to seeing 'cam lag' in this world of variable cam timing :D

[Rob]

what variable cam timing?

[Chapel]

VANOS
he's used to M50TUs and up
We rely on an 'on cam' power delivery rather than a variable one. Traditional power :)
Im most happy with the smoothed out line.

fancy talk confused me :P

Lucky for you Jared I have my dyno of my stock M20 w/ JC chip 8) The A/F is a little high, I'll take a picture of the graph tomorrow, but for now the ratio is never below 13.8.

yeah, most of the way its high 13s/low 14s
but then you can see at around 6000 it leans out to 15

Repost the picture, its X.

But my guess is 148.75 with 15% drivetrain loss?

This is your m20b25 dyno numbers?

Not bad, what do you have done to it?

:)

my website just went down...
so all my images will be back when Comcast fixes that...

yeah, its 148.6whp
right now I just have software
