Your B16A dyno results?

yonas had stock head IIRC

[ProECU]

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.

In my opinion, because Yonas's car makes so much power at very peak of rev-range, it isnt put to good use.

These two comments are contradictory. No?

[EG5]

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.

ALso when i ran the car , my rear disc was warp and still pull 96 mph
Every 1 cycle turn , it brakes by it self. too bad I sold the whole b16a set up already , im still itching to run it down the 1/4 mile.

[EG5]

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?

stock head
stock port

that explain it ?

Don't worry, i'm sure the new owner will give it a good bashing

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.

Everyone a simple way to understant to make light of what toda is saying..

If you own or have access to a coppy of nfs underground 2 try this.
1. build a supra 100 percent.
2. then go to tune.
3. peak everything to do with power right up last bar on tuning the highest (turbo and engine)
4. run on the dyno and look at the graph. (high power+torque in high rpm range)
5. test it on the quater mile, take not of your time.

Now start again but with do all of the above but with step 3 and 4 do this
3. try and run the power up from the 1st bar to a level and try and keep it as flat as possible.
4. dyno (your power and torque will be lower. but the power and torque should not tapper off and will be very flat)

when you do you quater you will realise you have done a faster time much easier. but you will probably have a slower mph, maybe 10+. this is because the car 2 isnt designed for higher speed but getting up to a high speed faster then car 1 and the quicker and more time you can spend at a higher speed then car 1 helps you cover more distance faster

stock head
stock port

A 3 angle valve job + CTR cams etc is hardly a stock head. I still also have some doubt around not being polished but you can have the benefit of the doubt.

Not bagging you or anything but the reality of getting this much power from a 1.6 needs to be clarified.

[tinkerbell]

um, what honda leaves the factory without a 3 angle valve job?

and e240 - the "power" you talk of is only a dyno number... on a "happy happy joy joy" dyno...

does that clarify it for you?

Tinky, so you're saying that the 119kw is not real? Then why keep emphasizing it in a number of posts?

Anyway, Toda's dyno have seen a number of B16as for its reading to be compared across B16as. So when a claim is done to have 119kws on a stock block when other standard B16As (and tuned) on the same Dyno have done far less, you can't say that claim is just a "happy happy joy joy" claim. Especially not when you're claiming bragging rights with it.

does that clarify it for you?

[tinkerbell]

i got 120kW on the same dyno (B20VTEC), i ran 14.5 @ 95mph on same drag strip.

seems to be fairly consistent?

what are these other standard B16A's you speak of? do they make 100kW?

which ones have I/H/E ITR IM & TB and CTR cams + springs and Hondata?

[tinkerbell]

cant find ANY posts in this thread mentioning B16A's tuned on Toda Au's dyno... except EG5's one...

care to point them out?

Not everyone from Toda posts their results here.

Based on your post, do you consider having CTR cams and springs as stock?

Maybe I'm just picky ya..
