Those running the Aster Bracket, let me know your pulley/belt lengths
 
HU Pulley.................... Idler Position
Diameter................... Close..... Center.... Far
3.25............................... - ..........50.5?...... 51?
3.4............................... 50.5....... 51.0........ -
3.55............................. 51.0......... -.......... 51.5
3.7............................... 51.5?....... -.......... 52.5?
3.85............................... -............ -.......... 52.5
3.9................................. -............ -.......... 52.5
4.00................................-......... 52.5*........52.6??*
4.13............................... -............ -........... 53?
4.25............................... -.......... 53.5........ 53.5
4.38............................... -.......... 53.5?....... 53.5?
4.5................................. -.......... 53.5........ 54?
4.63............................... -.......... 54?.......... 54?
4.75............................... -.......... 54?.......... 54.5?
5................................... -........... -............ 55.5?

NOTE: with a 4.00/7.65 combo, and a Gates belt that is K080525, I needed to move the idler to the position furthest from the blower. Maybe the belt stretched a little, but in the middle, the tensioner would bottom out, and I got belt slip. -The Alchemist.

Belt Matrix Chart when using the Aster bracket with the CBR 8.65 crank pulley:

3.70 pulley/53.0" long 8 rib belt

3.85 pulley/53.0" long 8 rib belt

4.13 pulley/53.7" long 8 rib belt

4.50 pulley/55.0" long 8 rib belt

Thanks, I added it to the link. It will take about ten minutes for it to show up from when I post this, as my website is currently saving the changes. Bob

You might try a 52.5" belt. Bob

I'm gonna go with the 8.65 and a 3.7. It's close to what i need. And it will be good when I cam the car too. I just don't want to have to switch belts and shit later on. So the 53 is what I'll use.

Gates makes them.
I've ordered that exact belt length in the past from Jegs.
Part# 465-k080515 HD for the green belt. Drop the HD for just a black belt.
You will have to special order it from them since they don't stock that part #.
I order belts all the time that they don't list.

Where is the idler placed. Middle or closed to procharger or passenger side

I tried putting my 53 inch belt on with the 8.65 and 3.7 or 3.8 I forgot at the moment and it wasn't even close.

I have the idler in the hole closest to the supercharger.
