maybe because they are planning on getting a s/c and they have the underdrive pulley?

semtex · 08-31-2009, 01:27 PM

Or maybe they don't like what it does to the windshield wipers.

KIDDING! (Sorry, I couldn't resist.)

Semtex,

Took me a second to realize you were kidding! Good one!

^ G3 if you're looking for big gains.

would it make a difference if you used a heat shield to block off the filter from warm air, or is the filter far enough from the engine with the g3 where you dont need one?

There filters on the Stillen Gen 3 are way out in front of the radiator, inside the upper part of the front bumper. They're not directly getting heat from the engine bay at all out there, although they probably do pick up a little heat from the radiator and/or any oil cooler.

I have a bunch of parts in my garage to do a Modshack-style ducting job to bring outside air directly to the Gen 3 filters, we'll see if it makes any difference. I don't plan on trying to seal over the filters like he did though, I'm just going to route the tubing to dump cold air right on top of them.

Good review and excellent pics. With as much as these cars tend to run temperatures of 220 to 230 I am surprised you chose to put on an UD pulley. Thoughts on this?

semtex · 09-02-2009, 07:29 AM

I'm not seeing the connection. What does a UD pulley have to do with oil temps?

He might be thinking the water pump is belt driven for some reason. I can't recall any car I've owned where that was the case (including the new Z), but I suppose some car must be set up that way.

Check out my DIY for ducting. I think your on the money as far as dumping air infront of the filters. There's all that dead space in front of them, forcing all the air that supplies the car to come from behind.

Yes I wasn't aware that the water pump on the Z is electric (I assume then?).

It isn't that "some car must be set up that way". Many cars are still set up with the serpintine belt driving the waterpump. That is why I asked the question. Putting UD's on a car using a belt driven waterpump, the pump turns much less than with the stock pullies on the car. So the cycling of water is much less.

Higher temps is something a person running UD's on a belt driven waterpump always has to keep in mind particularly if the owner decides to put a blower on a car after installing UD pullies on a car that has a belt driven waterpump.

ok the water pump is driven by the timing set(chains)

the power brakes run on engine vacuum

Why not make a pulley for the supercharger kit that overspins the blower to work with the underdriven crank?

Is the rubber harmonic section on the stock crank pulley just there for show?

Does a brother have to kill to get a timing scale instead of three stupid dimples?

How accurately is the zero timing mark located in relation to TDC (like less than a degree?)
