okay.. 265nm is a bit high.. fly's b20vtec has 300nms of torque.
does torque figures depend on dyno as well?
BUT, if you do actually have 265nm of torque, congrats to you, alot of torque for such little efforts.

That is a lot of torque to have at the wheels for a N/A 4cyl.
S15s have 265nm stock but not at the wheels
Nissan S15: 12.6@113mph
Integra GSi: 15.1@91mph
Civic B18c N/A : 14.1@98mph
CRX B18c N/A : 13.9@101mph

and its dependant on which gear the "run" is done in correcto ?
So basically, the torque reading is wrong.

True, true... Pays to look more carefully…
I looked at the dyno sheet again; the run was done in 4th which is pretty close to 1:1
So my bad…
The other thing I noticed is the SAE correction factor is 2.19???
Though I don’t use this type of dyno, but the most our dyno dynamics atmospheric correction ever goes is + or – 0.2 or there abouts from 1. Usual is 0.9~0.95.
Also of note are the A/F ratios…

Figures looks ok. I wouldn't say low or high. There a car floating around, Stock vti-r motor, with the same mods as you beside the cams, he's running sotck cams and pulling 112 kw atw. He's got 1/4 mile time to back it up.
The a/f looks abit on the rich side. Might make 1 -2 kw more if lean it out abit.

not wrong... correct for the gears' torque reading. That distinction needs to be made, always!

correct , but wrong in comparison to "other" dyno readouts in a different gear true ? This is the misleading to most people here.

Care to explain how you determined its rich?
the area of concern is the 14-1 before vtec.... damn you peak HP guys....
If he richened this thing to 12.5-1 in lower rpms he would gain driveability and the car would be faster than it is now, without touching peak power production!

so rather than conform to peoples understanding (or lack thereof), we should try educate them with the complete picture, and not feed them what they want to hear.
thats my point.

Adrian, that dynosheet looks like a mainline dyno printout.
I can tell you that we experience the same level correction factors as you mentioned above (all my work of late is on a mainline).
The interesting thing to note, is correction factors this high, are typically "manually" entered or overwritten on the mainline.

What u guys reckonz for a B18C with I/E/H and BC3+ cams.
Great work m8!,
with all that potential you've got to be cheerin aye! so is it going to be all bolt on's pfc's n tuning for u now? i hope you stick with the cams to see what can be built around them.
Cheers, HONDA POWER!!!
