Topgunz - air to air upgrade

ChaseZ · 06-15-2017, 03:07 PM

I have a spare pulley from an OEM tensioner I had to replace. It's bigger for sure but without meSuring it may be slightly too big. I've got some playing with things to do later on so will check it out at the same time.

That said, I'm more keen on changing the serpentine side pulley anyhow, provided I can find one that is the normal price. Looks to me like there is still enough room in the OEM tensioner that the belt I got from you with the extra idler should still fit just fine.

What's all this talk about various pulley upgrades? I thought you only ever replace the SC Input Pulley and the rest stay as they are...

little bit off-topic here but still related to these upgrades,

will be running similar to what topgunz is in regards to engine mods, what clutch is everyone using for around 500-550rwhp? I've been to a couple places here in Aus and they are telling me I need to go a button clutch anything else won't handle it which sounds a bit weird. our 370z's aren't torque monsters, any recommendations?

ChaseZ · 06-16-2017, 04:10 AM

South bend stage 3 daily is a good all arounder. If you are tracking, dragging etc then that's different though. All depends how you use it.

MoulaZ · 06-16-2017, 07:55 AM

I'm running a Southbend Daily Stage 3 as well. It was about 30,000km old too by the time I got the SC on there and it's still holding fine for now.

I second this. I ran mine at 530whp and 480wtq for over a year on a single turbo that ramped torque in hard and fast and it never even thought of slipping. Switched to the SC and it seen even less torque so zero chance it will slip. I would push this clutch to over 500wtq all day and the SC's wont get near that level. Plus it had a stock feel to it. Id buy it again in a heartbeat.

Second this too.

My Southbend Stage 3 Daily is arriving TODAY from ZSpeed.

ChaseZ, You are correct. The Stillen 9lb pulley replace the silver 8psi pulley (jackshaft) on the serpentine belt side. See attachment.

Was going to grab a 9psi pulley, just to clarify it sounds like the Vortech one goes in the SC backside of the jackshaft where the Stillen one goes on the front. Correct? I hadn't contemplated there would be a difference but stands to reason there is I suppose.

I actually had one before and wasn't going to use it so I sold it. Which of course I now regret.

TBatt · 06-16-2017, 09:11 AM

My search for the larger idler pulley to use on the SC belt when changing the SC pulley to a 9psi setup (2.95 inch) has been very frustrating. I have been using the search tools but keep coming up empty on the part number.

What I did find is the pulley needs to be 76mm in diameter and I think the width is around 32mm. This weekend I will take some measurements of mine and then get the PN from the Gates catalog. Hopefully I can see the PN and remove all doubt.........

As an FYI: the SC belt is a Gates K08022 or Magnuson M-79-08-02-020.

Vortech 2.95 SC pulley is PN 2A038-295
Idler pulley needed is (maybe) Gates 36225. I need to verify this!

ChaseZ · 06-16-2017, 10:20 AM

For reference the pulley off the OEM serp tensioner is 71mm
However it's probably only wide enough for a 7 rib not 8. Ere is a pretty substantial flange around it which could probably be machined off, but for the cost of a pulley likely isn't worth the effort or expense.

Does anyone know where you can get a Stillen 9lb pulley?
conceptzperformance.com just ran out.

Stillen 9lb pulley is 2.75" 7 ribs from what i have seen on other forums. Correct me if i am wrong.

So I would need to find a similar pulley. Maybe from Vortech. Let me know if anyone finds one please. I will keep looking.
