kenne von gfb nur die blowoffs und die sind qualitativ sehr hochwertig und gut!

Ja, ich kenne beide. Das 500$ Blowoff habe ich mittlerweile rausgeschmissen, ist undicht an allen Stellen, verdreht sich von selber.

Das Pulley ist SCHROTT, da kannst Du Dir genausogut eines von OBX holen für 80$. Begründung: Da ist kein Dämpfer drin.

Okay, das wollte ich wissen.
Auf der Homepage stehen keine Infos. Sah halt schön verarbeitet aus

Es gibt ein paar Pulleys, die in die Wahl kommen:

- ATI Super Damper (brauchst anderen Lima Riemen 935er)

- Ross Tuff Bond.

Power Bond Race

Image
The Nissan Sylvia 200SX and the SR20 turbo engine are one of the world's most popular 4 clyinder performance combinations. making big power from these engines is easy but severly tests the safety and durability of many parts including the harmonic balancer.

All serpentine belt engines including the Nissan benefit from under-driving the accessory pulleys to reduce parasitic power losses from the alternator, air conditioning, water pump and power steering at high engine RPMs. A smaller, lighter harmonic balancer is like a lightweight flywheel and can sharpen throttle response and allow the engine to rev out faster.

Powerbond have now released a 25% under drive billet steel balancer for the SR20 that is SFI approved for all forms of motor sport. The precision CNC machined steel hub and inertia ring is assembled using Powerbond's pressure bonded rubber eliminating balancer separation and spinning. Every Powerbond unity is dynamically balanced at the factory for smooth running at ultra high RPMs.

Pro's: Unit looks great, light weight, well built, nice finish and been around for years.under driven by 25% so its the balancer for race sr20's on a budget but don't want to cheap out on a important item such as this.
Local made as well.

Con's: They sometimes need to be honed to fit the crank as they make them to tightest factory crankshaft spec. Which is good but a pain if you buy one on friday and want to go racing on the weekend.

Price: $260, Crazy cheap,

Lighten crank pulley.

Without trying to sound clichéd, the GFB SR20DET lightweight underdrive crank pulley is new and improved! Of course, it can't be both new AND improved, so we'll go with improved!

It has been re-designed to further reduce weight, and more importantly, a steel wear sleeve has been fitted to the oil seal running surface (shown below) to greatly increase pulley longevity and eliminate potential oil leaks caused by wear over time.

Suits SR20DE and SR20DET engine in rear-wheel drive configuration only

Pro's: It looks nice.
Con's: It is NOT a balancer, it is infact a lighten crank pulley which is a big NO NO!!!.
It will not do its job,let the crankshaft walk,damage front and rear oil seals. and in turn is NOT upgrade,
Sand blast the factory unit and anodize it, Just stay away from this unit. It is not a balancer at all

Price $249
