No idea atm. they in developmental stages. no actual cams have been tested as of yet. well at least to my knowledge

I heard the Stanza Altima pulley was maybe a tad bigger than GSpec and UR but not sure how much bigger. Might have to see if I cant find one or order one in and see.


Yes, the Stanza fan/water pump pulley is a little bit bigger than the GSpec WP pulley but the GSpec pulley already underdrives the water pump more than enough to prevent cavitation at high engine RPM's. The Stanza pulley is large, which is good at preventing cavitation but it also weighs more than double that of the GSpec pulley. The added weight would take away any throttle response and/or added HP you get from switching to a lighter aluminum pulley. Plus, at $53.00 Greg's pulley is cheap enough not to worry.

Also, I got your email, but haven't had a chance to look at it yet.

The Stanza W/P pulley doesn't affect throttle response IMO. I have both and am running the Stanza pulley on the track car and the G-spec in the street car. For the OP the G-spec will work just fine. The Stanza pulley for me is added insurance on the road course where the VE will see 8K+ on a regular basis for 20 minute sessions and where cooling is a must without any cavitation issues. For street use the G-spec is the better choice.

Then stanza would be good for me as well since I do plan to track the car once i get everything to where I want it to be at

I was under the impression, from some research, that the Stanza pulley weighs more than double that of the GSpec pulley. If I am wrong, I will stand corrected. Do you know what the weight of your pulley is? I have never personally weighed one.

I do know that going from a RR WP pulley, which weighs less than 7 oz. to a GSpec pulley, that weighs appx. 5 oz. showed a noticeable increase in acceleration. A lighter pulley would certainly be my preference, for the WP anyway.

The Stanza pulley is a few bucks at the Pull A part. You just have to find one

Personally I'm unsure of the weight of the Stanza pulley but I had no choice in which pulley to go with because of the dual duty of my track car. It can be a daily but because of the brutal conditions of road racing in AZ during late spring and late summer I don't want to lose another motor to cooling issues as I did a year ago. Couldn't afford to have any possibility of cavitation during the kind of abuse the VE goes through during a weekend event. For anyone else deciding on a multi-purpose pulley I think the G-spec is still the best choice. If you plan on serious track use the the Stanza pulley works the best IMO. Acceleration differences were negligble but this is applied to road racing only.

I can appreciate your cautiousness with not wanting to lose another engine due to overheating while road racing. During extended rips at constantly elevated levels of engine speed, I can fully understand your choice to run the Stanza pulley. It is proven to work as lots of people have done this mod for track duty cars over many years. Under the same circumstances I might be convinced to give up some throttle response for some added temp. assurance. You can also get a BNIB Stanza pulley for $38 so why not, if you're so inclined.

Agreed. The best of both worlds.

Real world impressions are always a nice thing to have and hear! I would imagine you would feel the difference if you were to switch to the GSpec pulley for road racing (with the same setup), but understand the reluctance to do so.


Kirru, here is a nice little article on cooling, for road racing purposes.
