I've got a K20a2 DC5 Type R AUDM. What pulley size and belt would I require for 7psi? I'm under the impression that I need a 3.4" blower pulley. But on pulleyboys.com, their sampled psi chart states 3.2"bp for 7 psi on a type r.

conradb212 is an unknown quantity on c-rsx
My 2004 Type S has been supercharged for 11 years. Over that time, the only problems I've ever had with the car were with the belt and tensioner. And that's WITH expert professional care (Comptech/Driving Ambition). It's my opinion that the belt/tensioner situation can be optimized, but never totally resolved. That's because by asking it to drive a supercharger on top of everything else, we're asking that whole serpentine belt system to do something it simply was never designed for.

JRSC 3'' pulley no p.s.

So i can not find a belt to fit my car anywhere and i havent been able to figure out anywhere on here what size i need. a 60.5'' was to tight and a 61'' had way to much slack..

k20z1
stock tensioner
3'' sc pulley
no p.s.

To be honest, I don't think you need it. I swapped my pulley without it as the JRSC kits for the RSX are not pressed on. You just need something to hold the pulley while you crack the nut with a rachet and good socket.

for anybody crazy enough to dig through this thread for actual useful information, for my 3.4" blower with AC and PS and stock crank pulley, I used a Dayco 5070825 which is a 7 rib 82.5" long belt. Fits perfect. Other sizes at http://crossbelts.com/serpentine/kbeltsizes.html

What belt size? Currently using a 48.5" 6 rib belt (getting alot of belt squeal and belt hop) Starting to think i may not be using the right size belt and i can't find a 7 rib in the same length.

Anyone using the same setup? What belt are you using?

Holy crap. Maybe someone can modify the first post to actually help with Motor/accessories/belt options?

Side note, I read through most of this and cant seem to find my combo. Anybody have this setup that can help with belt numbers?

I am wanting to start off with K20A Crank pulley:

1. K20A motor with NO PS and NO AC Stock tensioner with 11 pound pulley from merc racing.
2. K20A motor with NO PS and NO AC Stock tensioner with 8 Pound pulley

If not enough boost I will change to the K24 crank pulley.

3. K20A motor with NO PS and NO AC Stock tensioner with 11 pound pulley from merc racing.
4. K20A motor with NO PS and NO AC Stock tensioner with 8 Pound pulley

crackerjack is an unknown quantity on c-rsx
crank pulley

I have just switched to Honda CRV 07-09 crank pulley at 6.5 inch. JRSC kit.

3.0 inch charger pulley and I have CT auto tensioner. The AC and Alternator spacer is
there to take up slack.

The AC spacer is half inch spaced out. Original belt size is 4070775.

K20a2 pulley is just under 6 inch at 5.95 inch. So to make the 40775 belt fit, I simply put a smaller spacer in the AC spacer and everything fit just fine after.

If you decide to delete AC or PS just make sure you use your old belt or a string to figure the new size and belt will stretch as much as quater inch after break in.
If you cannot find a size that you want, you can always play with AC and Alternator spacer to make a longer belt fit.

Happy belt hunting.

Update! Unsuccessful at finding a belt in the size i needed for my set up. So i swaped the K20A2 CP for a K24A2 CP.
A Gates 49.6" Belt is a perfect fit! Only comes in 8 Rib so you will have to cut one of the ribs off. Hope this helps someone in the future.
