The previous sites are a bit confusing to navigate.
Here is an other one that seems a bit cleaner and should facilitate the
translation from Portugese to English
http://www.mataddesign.com/asas/index.htm

Be aware that most web translators dont come close to doing realistic
translation.
Mr Coelho's name translates as Altair Rabit.
He has a number of interesting aircraft designs to his name. ( see under
"projetos")

under "Vendas" (sales) we arrive at

http://www.mataddesign.com/asas/mecan.htm
according to this he offers 3 diferent redrives.

1) AC 51 a V belt unit for VW conversions rated at  80 hp
2) AC 53 a cog belt unit rated at 180 hp w peaks of 200 hp
3) AC 54 same as AC 53 but rated at 120 to 140 hp

the text for AC 53 as translated by Babblefish and some additional clean up
reads as follow:

Reduction for engine VW AP-2000 Makes real the dream to fly for those people
whom they desire to construct an experimental airplane. The use of the
PolyCHAIN belt allows a compact construction due the biggest capacity of
transmission of power with lesser width of belt.

To handle the aspect of torcional vibration the following measures had been
taken:
- Use of integral projection
- Application of a harmonic pulley
- Elastic Coupling
- Determination and positioning of the elasticity of the supports of the
engine

Its initial calculation was foreseeing the power use up to 180 hp with cycle
of 6/6hs of functioning with 200 peaks of hp for 5min. at 5500 rpm.
A minimum life of 2000hrs  is estimated for the belt.
- Ratio: 1,8x1 or  1,9 x 1
- Project: Altair Coelho - 2003
- The engine positioned vertically thus allowing one better drawing of the
front cowling of the airplane.
- It Is increased approximately oil capacity in Carter in 1,5 liters.
- Motor AP 2000 ( VW) in cases in the same position of an aeronautical of
150HP.
