It is a favorite light weight pulley by Japanese tuning car. The one for VR6 was found with site of the foreign countries. This pulley Sets are CNC-machined from lightweight 6061-T6 aluminum billet. In other words, ・・・・ is light!
If it is reworded, the power of the engine isn't taken by force by a pulley, and it is conveyed to the wheel.
It is explaining with site of the manufacturer with 8-15 horsepower gain.
Really? Well, let's try it.
Unorthodox Racing Ultra Street Sets
When it tries to measure weight, it is 0.9kg.
When it is read that it is written in the received box......
ODB-Ⅰ+10-15HP is written.
mufufufufufufu！
Well, shall I install it?
However.......
????????？
Crank pulley....... It doesn't come off even if it is tried how many times.
There is not even the sign which becomes loose.
Because it is inevitable, the first challenge is defeated decisively!
First of all, CRC is blown, and it tries it after one week!
In doing the second challenge.
It goes, and it is still defeated decisively!
Used Impact wrench are four units!
It was no good though it escalated freely with 40,60,80,100 kg/m and the big thing of the torque was spent.
I was completely at a loss.
Is the third challenge necessary?
It was the third challenge at last.
In it removes a starter unwillingly, and thrusts a screwdriver in the hole of the Flywheel, and fixes crank and turning it.
It could be removed somehow in this method.
Still, it seems to be very difficult to remove the bolt which isn't being removed for about 10 years.
Headlights are removed, and it is the difficult work that it is removed with Impact wrench from the space.
Because the number of the rotation of Alternator decreased, it is worried about a battery's being exhausted during the traffic jam.
Is anxiety unnecessary?
Torque crank pulley bolt to 74 ft-lbs/ 888 in-lbs/ 100 NMplus an additional 1/4 turn.
From the left, Alternator pulley, Crank pulley, PowerSteering pomp pulley.
This time, three pulleys indicated blue were exchanged.
The result which it tried to exchange! It is great!!!!!
It is the best mods I have installed yet.
I tried dyno again on February 25, 2002.
The result.....!!!!
It was on the increase from 167WPS to 178WPS.
11WPS was on the increase, too.
Great!!
Though it had difficulty and it was installed,
there was the installation instructions on site of Unorthodox Racing.

I should have seen it better.
The farthest way about is the nearest way home.
