Nice find. Too bad I just bought a pulleyboys pulley.

[lilcoop_69]

Has anybody tried that pulley here yet? I'm looking to get a smaller pulley also sometime in the near future.

[choi0706]

it'll work for sure..

[mr johnson]

love to but then i'd need an upgraded fuel pump and a re-tune...

[choi0706]

So, I spoke with NST.. They expect their batch of pulleys to be in stock mid march..

Can you do me a favor and find out the exact PSI readings for each pulley size (3.4, 3.2, 3.1, etc)?? I'm seeing too many different results from different people/vendors. It'll be for my supercharger FAQ, which I really need to finish. Thanks!

[choi0706]

it's hard to measure it.. the psi varies soo much, it's hard to give one pulley one reading... plus, I don't know if you've measured boost on the second cam it moves around alot..

[choi0706]

Just found out they're in stock..

Hi!

I 've purchased and installed an NST pulley on my Corolla and I am very happy with it. The weight is a bit less than the GReddy pulley and its construction seems to be sturdy and durable. Needless to say that performance improvement is MUCH more than noticable, especially on the 2k-5k RPM range.

Personally, I would recommend this upgrade (along with an ECU re-tune!)

what's the stock Greddy pulley size? 3.3"?

you are bought a 3.2, 3.1" pulley?

[GoatOfRafin]

Hi!

Stock pulley is 3.5" and I have bought a 3.1" (I think that NST does not have a 3.2"). According to my calculations, the 3.1" is safe as far as supercharger rpms are concerned.

Having a rev-cut at 8700rpms (that's my rev-cut), the 3.5" makes the supercharger rotate at 13.050rpms and the 3.1" at 14.730rpms. Eaton states that 16.000rpm is safe for burst rpms and I think that some people have stated here that burst rates are safe with rpms as high as 20.000 rpms.

So... "rev-wise", this setup is safe.

I thought the stock was 3.4"

[GoatOfRafin]

Hi!

Might be... I thought it was 3.5" but I am not quite sure. Maybe the more knowledgeable guys here will care to post about the exact size...

G.

[choi0706]

Yeah, lots of folks have said the OE was 3.4

[choi0706]

who else have tried the pulley? I'm wondering what kind of experiences you guys have had..

[ahnjae]

what kind of boost is this pulley reading at sea level?

Works fine (NST), i dont want to talk about boost because it debends so much about your vvt tuning.

Did not get dynosheet yet because clutch started to slip. But with little vvt-tune it started to feel fine.

+1 there will be at least 5 different readings for different cars running different tunes.. good luck trying to peg X.X" pulley makes Y PSI..

[Korben007]

I think we should just list what size pulley spins the supercharger at x rpm vs engine rpm

[choi0706]

that is true...
