Ok so i was wondering what kind of gains you get after a build just trying estamate my current power. I know the build itself doesn't really give you anything but balancing makes everything work smoothly so it must give you something.
horsepower gains from balancing

Its not going to "give" you any power unless you rev the engine higher. Balancing it will ensure that your motor doesnt wear prematurely - it will just make your motor last longer.
but because it is balanced it's not fighting it self so it does free up somekind of power that would have been wasted trying to rotate. im not trying to start a fight but no one try to tell me it doesn't free up hp because i know it does something just not how mucheven if it's very minimal. it could be so little as 1/2 a hp but physics will tell you something that works well together is going to creat more power.p5150 said:
An unbalanced engine will vibrate - perhaps it will give you more power, but I think it is negligible. The reason people get their engines balanced is not for power gain; its for reliability.

Well - that may not be far from the truth, because you can safely rev an engine to higher rpms if it is balanced better.
So you arent getting the gains from the balancing, you are getting the gains from higher revs which are capable in a balanced engine....
Am I making sense?
You're making perfect sense p5150.
It's just unfortunate that whether or not it may be viewed as a joke on here, many many many people believe what they see in video games to be true, which I find hilarious.
I actually had one guy ask me what level weight reduction I had on my car one time.
I told him "level 3" and he was shocked and said something about that costing $20,000
lmao
You are right though. The primary function of balancing the engine's rotating assembly is to make for a smoother running engine that won't eat itself at higher RPM's. Some horsepower is a byproduct of this, but it's not the main focus of the exercise.
Just like a lightweight flywheel.. claims of 20hp and so forth, when really it just makes the engine rev easier.

my original post i was kinda kidding, it's a video game. but what's the use in allowing your engine to rev so much higher to make more power unless you change other things (giant turbo) to make power up there? it can't climb forever

i'll just add a couple cents here...
balencing remove's the vibrations caused by harmonic's of the rotating parts. (sounds good right?)
in other word's , if the weight of each piston, pin, rod , rings, are the same, and the crank is done aswell there is no forces working against each other, thus each power stroke only waste's the same amount of energy pushing the next piston to fire.
the motor seems to rev smoother and faster,
i just had my crank lightened a pound, and he ended up removing 1.25lb also knife edged the crank a bit, doing this ontop of a previous balence job, then had it rebalenced with a aluminum flywheel set up,
i know it's going to rev faster, but i doubt i am going to see an power increase n/a wise, thougth a faster reving motor would be more responsive, so it would feel like it had more power.
i have a feeling that a quick reving motor will build boost much faster then stock, and having a lighter rotating mass, and all in balence, i think skating on the redline shouldn't be a problem...
only problem is going to be looking for the right crystal to change out in my ecu to raise my rev limiter to 7.5k

Or how the 2JZGTE, 1JZGTE, and 7MGTE Fully modified on GT4 only have a ~100 HP Difference... And the MKIII Supras have four right-side sawblades... *Sigh* I have too much time on my hands..
if you take an engine that has say 232hp at the crank, and for some odd reason, say you take the engine out and apart, balance and blueprint everything (they are different) and put it all back together without changing any internals, you will still have 232hp at the crank. yes it will be a much smoother rev.
in order to gain more hp, you need to raise compression. installing a clutch, or 3 in exaust does not give any hp, it simply lets more of the engine's hp reach the ground.
and blueprinting is when everything is to an exact measurement of what it is supposed to be. if a head bolt is supposed to be tightend at 85ft.lbs. +/- 1ft.lb from the factory. it might be set at 84, 85, or 86ft.lbs. if it is blueprinted, every head bolt is set at exactly 85ft.lbs. and so on for every other part. at least i think anyway. this is what i have been told.

The more something is balanced the more efficient it will be in delivering power... now I'm not saying it's going to be like 10hp, it should be more like 1-3hp WEEEE. Hell even putting you're spark plugs pointing a certain way will give you like 1/2 an hp.

this is what i was trying to say i know it's not much but it is a few just wondering if anyone took the time to find out really how minimal it is. I do understand the point and i also understand more is not the goal just wondered what the extra might be, minimal or not.
My friend just bought it. Oh and GT2 too.
carbon doesn't have the MK3...or does it?? I have an MK4 right now, with my favorites iForged Aero...dream wheels. But really is there an mk3 in that game?
