Help understand my dyno graph

[mag9556]

Initially, I was disappointed. But after seeing the comments from you guys here, it made me feel better. I know the money spent did not go to waste.

Mind to tell how many BHP would be considered an achievement for a 2L? When I read back the previous comments, I don't see anyone mentioning about that la? Or I must have missed it between the lines. Just got up. My "ECU" still not registered yet.

Actually what u said is correct, must be happy for what u get at current as the more BHP u mod, there will be someone faster than you...
Just like you are dumping all your $$$ into the seas...
I got one friend modded his Wiralution very fast.. 400WHP.. what use... 60k trow to mod the engine at the end at also sell off the car at a very very cheap price thus lost to Ferrari and also Lambo at highway...

Be glade of what we got now and speed kills but mod will not kills...Happy modding

I said 100HP/LITER (of engine displacement), not 100HP as an absolute value! :) So for a 2ltr car then try to get 200HP. How many NA cars on the streets today can reach 100HP/ltr? Still very few only right? Mostly all considered high performance/sports car already, like Honda Type-R, all current Ferraris, Lambos, some Porsches, M Power Bimmers. :) But again max power numbers be it HP/ltr only tells just part of the story, more important is how linear the power is produced cause that determines the way it drives. That's why many car manufacturers still do not make engines reaching 100HP/ltr, the most obvious example is Mercedes, but their cars are still plenty fast and pulls like mad due to the very fat torque from big2 engines.

Ohh.. ok ok.. sorry sorry. Salah read your post. This makes much more sense in comparison!

And like you said man, who cares about HP? It's torque I want!

if me, i always want hp. then see how the torque curve go. then tune the gear-ratio accordingly. because when we have high power, there must be a torque in there. or else high hp cant be achieve. (remember: torque X rpm X * = power). human leg can produce more torque than a motocycle engine. but why bicycle always slower (a lot) then motobike? because our leg's big torque only came at around maybe 10-50 rpm.

Don't rush into things. Evo IX equals serious commitment. Take it slow. Don't be like me. Every thing I spend on the car is impulsive without thinking about tomorrow. Hehe. Btw, I have a friend wanting to sell his Evo VII if you are interested. All I can say is that Evo VII is a monster and beauty. More like beauty and the beast in one.

Yes, I know it's a serious commitment to buy and maintain such fast machines. I'm just a bit tempted whenever I saw one in good condition for sale!
I like all evos from 1-9 (but not the 10), but in terms of owning one for me E7 is a bit too old already but the price nowadays is dropping below 100K ya. So far I'm only tempted by the E9 or maybe E8MR. If going for old ones, maybe E6.5TME but that's very2 rare/difficult to find in good condition, most are pretty much abused already or want to sell at exorbitant prices!

Ok, first, hp is torque x rpm. Basically, more torque means more power. But since engine doesn't operate at one rpm and instead over a range of rpm, you get different torque at different levels. But basically, at any rpm, the more torque you have, the more hp you will get.

The hp (bhp or whp) figures, it depends on which dyno you go. Dyno Dynamics will net you the lowest figure in terms of figures compared to DynoJet. Dastek Dyno (RS Dynotune) give power in bhp. But the most important think is not which one is accurate or better, just don't try to compare dynos from different dynos.

The figures from dynos are the numbers in WOT, where you slam your accelerator pedal to the max and get the torque and hp curve. Your figures is quite linear really, and can be broken into two parts. Without even you telling others what your car is, one can know its either a MIVEC or a VTEC.

I get it now. My mech told me that if I use a suitable camshaft I should get a more linear torque curve. He also said with a hi cam, the VTEC pull won't be so obvious as compared to now. I remember him saying something like this.

- What your mech says is correct. VTEC gives you the hard pull because there is huge characteristic difference from the different cam profiles. When you change cams, the profiles different between the low and hi cam might not be as obvious, so you don't feel it is pulling as hard but it is really pulling harder. Imagine this, if you sit on a friend's car driving at constant 140 km/hr, you don't feel fast. But if your friend drive at 60 km/hr, then suddenly like mad cow slam the pedal and drive to 120 km/hr, you feel it is pulling hard and fast.

Thanks all. I some what understand the graph now.
