Bigger crank pulley

Post by **RattyMcClelland** » Sat Jan 16, 2016 7:45 pm

Guys does anyone know what crank pulley we use that's bigger.
I basically want to spin the belts faster that will spin my supercharger faster to 12psi.
I have heard the accord pulley is the bigger pulley but I have checked and the h22a7 pulley is the same part number as the Preludes.

Honda state is the same part number.
H23 crank pulley is bigger but has one less rib on the belt. No good to me.
Maybe one from the other accords.

I think it's the f23 crank I need. Just need to confirm the belt run count is the same and if I then need to underdrive the alt and power steering.

I think we need to use the NORMAL Accord Pulley

No ATR. but I will have a look at this on Monday.
We could also use this one on the Charger

not a bad price but as it says depends on crank pulley size

F20 crank is a single belt pulley so no good.
F23 is the pulley I need as it has the same belt sizes.

As for the merc racing pulley.....maybe. It's a smaller size so could work.

Think about it.

That won't fit. Looks like a different length. I bought the Merc racing modular inlet to replace the jrsc s tube and it took 6 months to arrive.

I was working on my father in laws accord with the f20b6 engine today and the crank had the same amount of ribs and looks larger.

So you can bought a 2001 2.0 vtec accord crank de wack pulley off ebay for £28 delivered.
Shares the same part number as the 2.3 type v f23 engine.
