Neutrale balansassen te koop aangeboden. De makkelijkste en meest betrouwbare manier om de balansassen te verwijderen. Goede inbouwinstructies op internet te vinden.

Nieuwprijs aanschaf, verzenden en import: 311 euro.
Doe een goed bod en ze zijn van jou.

Helaas kan ik ze in mij blok niet gebruiken wegens eerdere aanpassingen en ben ik genoodzaakt een electrische waterpomp in te bouwen. Erg veel werk en een stuk duurder om vrijwel hetzelfde te bereiken.

ZZP's Neutral Balance Shafts for the Ecotec motor mark another milestone for the community. Outperforming other products of similar function, these are simply the best you can buy.

For a good explanation of the function of balance shafts, read our tech article here: http://www.zzperformance.com/cobalt_ion ... .php?id=63

The best solution for building a performance motor is removing the balance shafts entirely. This requires changing to an electric water pump and plugging rear oiling holes. For most people, changing to neutral shafts is the best solution.

These shafts help you in 3 ways.

-Less vibration. As the tech article explains, these shafts cause a cancellation vibration that works against you at higher rpms. These neutral shafts eliminate the HP loss incurred from creating this vibration. They keep your engine safe at high rpm.

-Less weight. As pictured below the ZZP shafts are lighter than stock. Lighter cars perform better in every way.

-Less rotating mass. Balance shafts spin at twice engine speed. HP required to spin an object rises exponentially with speed. Balance shafts on built engines can spin in excess of 16,000 rpm!


So how much HP is saved?
This is a difficult question to answer because the truth is that it depends on a variety of factors. With any neutral shaft HP is gained at higher rpm because you are not creating a counter vibration for the car. The higher the rpm, the more HP is saved and it rises exponentially.
With the ZZP shafts, HP is saved because you are not spinning as much weight. The faster you spin your engine, the more HP is saved. With our competitor’s shafts HP is lost here.
If you look at kinetic energy formulas, you get an idea of how engine speed plays a roll.
KE = 1/2 (M * (V * V))
Let’s say it takes 1/2 HP to accelerate the shafts to 2k engine rpm. It would then take 2 HP to accelerate them to 4k rpm in the same amount of time or 8 HP to spin to 8k. Every time you double the speed, it requires 4 times the horsepower to accelerate in the same amount of time. Considering these shafts are spinning twice engine speed, you can see why it’s so critical to run a light shaft.
Compare the ZZP neutral balance shaft to our competitors. Their shafts weigh 2.5 times what the ZZP shafts weigh! This is actually more than the factory shafts weigh, costing you valuable HP.

Kan een slotje op. Zijn onderweg naar het werk van de nieuwe eigenaar.

@de nieuwe eigenaar: succes met de inbouw. ben benieuwd naar het resultaat.
