Your B16A dyno results?

stock bottom end means stock piston , stock rods .
untouch block

Yes, correct. The whole engine is as I purchased it from Asian Auto spares.
Head hasn't been touched either. So that means the engine is totally stock internally as far as I'm aware.
Daniel B16A - yes an S100 with tuning will make a difference on an internally stock engine.

think Yonas did 14.5, but apparently that was on his bad day.

Yes but at what MPH as that will show true power as with 119kw it should have run over 100mph in a EG and the ET should be in the high 13's.

i got 120kW on toda dyno and ran a 14.5 too? at 95mph...

Yonas's car has a high peak power but makes no torque.
Peak power & peak torque arrive together at 8500rpm.
My apprentice's EG6 makes only 110kw but loads more torque than Yonas through the rev range.
Though they have the same car, he runs 13.4 @ 100mph with 9kw less.
More area under the curve makes for a quick car.
High peak power numbers are fairly meaningless if the power delivery isn't linear.

how so very true. area under the curve always counts more in most case than not (unless its an all out drag assault and u sit @ ur peak power all the time)

Does torque not make HP,yes it does so the one with 119kw should run more MPH even with a slower ET.

In this instance, the one with more power has less torque.
That is it's mean torque & it's peak torque.
Torque is HP at a particular rpm, the higher the HP & the lower the rpm the greater the torque.
The 110kw makes a lot more power than the 119kw car for 90% of the rev range.
To be honest, Yonas's car would be hard pressed to pull the skin off a potato, let alone impress on the 1/4 mile.

So that EG6 has some very different modifications compared to Yonas' engine to achieve much greater mid-range but sacrificed top end power?

I am just quite confused that can't Yonas' engine be tuned with more mid-range or what you did was the optimum solution already?

I'm sure Adrain will explain why this is, I would say its in the cam timing.But it also could be one of his bang for buck final drive setups in the one that ran 13's and better tires.

Just noticed something that this thread started in Nov 2003 and now its getting people interested.

Drag needs mid-top end power + torque. If the majority of your torque is over vtec, you should be getting better times than a car with lower (but broader) torque/power.

Watch this vid of my drag last week in b16a and tell me where in video my revs drop under 6000rpm. There is no use for low end torque on dragstrip. In my opinion, because Yonas's car makes so much power at very peak of rev-range, it isnt put to good use.

IMO, a good time in a street FWD honda (my case a delsol below 15.000) should have consistent torque above 6000rpm with peak power around 7000-7500rpm.

and I also don't know all this about standard bottom ends...
Its all very misleading in trying to boast how little was done to get the the power up.

The B16A makes power from the heads, why don't describe the amount of work that went into the heads to make these sorts of power?
