I took out the belt yesterday. I can feel the engine respones better. Just like adding 5-8hp to it. I can't feel any additional vibration during idle or rev to 8000rpm. Maybe I put on two Head Balancer from SEV. It helps to reduce engine vibration to increase hp. It works! It is very popular in japan. http://www.sev.co.jp

This is not my engine. It just a friend's f20b with SEV-HB.

 

Ive never heard of a head balancer..

how much do they cost and are they proven to work or what?

 

Yes it really works. The SEV is very popular but also very expensive in japan. They have full line SEV products for intake, exhaust, damper, fuel line ......etc. The HB is a new released product from them. It cost 16,000 yen for one piece. I have two stick on the intake side of valve cover. The engine get smoother and acceleration also improved .

 

i need a fuel line damper, that damn 255gph walbro sounds like a freaking hairdryer in my back seat, i can't read japanese, so i don't know jack about what's on that site

 

What's the premise behind it? I certainly don't see much in that pic that might reduce vibrations . . . .

 

According to SEV,
Due to the heat dissipation action of the conical type metal inside the head balancer. The excessive heat which occurs during combustion is absorbed. It helps to release heat quicker. The effect are combustion efficiency substantially improved, engine become quiet and the engine response improves dramatically.
This is all I can tell you.

 

so are those just weights or what? And how do you know where to put them?

 

Here's some babel fish translations:

When the engine turns at high speed, the mass air passes induction system naturally that much, but the part where the air does not pass in the wall accompanying of the inlet pipe with air resistance occurs at that time, the phenomenon where the air quantity which is necessary for combustion does not enter happens. The SEV succeeded in efficiently sending the air into the engine by disassembling the molecule of the air which becomes resistance. </TD></TR></TABLE>

Something to do with the ionization of molecules so they're more stable & freer flowing? Hard to tell. It looks like they use the same kind of thing to supposedly improve everything on the car - shocks, brakes, wheels, tires, ride quality, intake, exhaust, vibration, blah, blah, blah, blah.

Wish there was something in English on this.

So . . . . by putting this fancy sticker on the top of my engine it will dissipate heat more efficiently . . . which will make the engine quieter & reduce vibration?

I'm pretty skeptical.

 

Im removing my belt next week because its not on right and im sick of the horrible vibrations. plus i want some more power. so can you really feel a good gain?

 

anything wrong with removing the balancer belt, any engine damage caused in the long term effects????

Nope . . . . it's just a comfort thing.

 

This sounds like a crock of sh*t. Kind of like how cow magnets give you better mileage... or electric superchargers... or magnets in your shoes...

Oh and I call BS on anyone who's "Butt Dyno" can accurately read 5hp.

from 2-4k rpm 5hp to the wheel would definately be noticable, on a prelude anyways...

 

lol thats funny ****

 

what are balancer shafts and how much do they affect your car if you tak them out? thanks
