Who;s got them for less than a 100 ?

 

Actually, the question is, who has them at all. Allen's supplier (Pulley Boys) is out of commission, so he was forced to find another. There is supposedly a new batch in production from a new supplier but no ETA as of yet. Perhaps you should contact him directly. There seems to be no other maker of aftermarket Radix pulleys out there. Let us know what you find.

 

Speed Engineering can get them cut for 170 a piece.
TByrne has some, only down to 3.0 for 110 a piece.

That's the only 2 I found so far.

 

That's crazy, $170 each.

Are TByrne's the Pulley Boys pulleys? I saw one of theirs and wasn't too impressed with the design. The ridges on the pulley are pointed, not flat (like they're supposed to be), leaving little area for the ribs on the belt to contact. I would be leery of putting a Pulley Boys pulley on a rig of mine.

What size are you looking for? Is this for you (do you have a Radix)?

 

I have a 2.75" that is too small for my use that you can have.

But I am looking for help with a water/Alky injection system to work with the Radix. Do you know anyone that has done it? The reason I ask is that most of the injection systems are added to Whipple's etc. that are a wet systems. I am concerned because I have heard that those who have tried to install Nitrus have had the Blower come apart on them so I am worried as to what will happen if I add the Water/Alk system.

 

I could try that 2.75, but I'm thinking it may be a little small. I'll PM you about it.

About the water/alc kit, that's not really a power adder, it's strictly to soak up the heat in the charged air. The water and alcohol mix soak have a cooler temperature to them anyways. As far as plumbing the system up goes, I would think that if you just put the jet in front of the TB in the plastic tube, that should be suffecient.

 

The altitude here is 567' above Sea level so I ended up with 12.5lbs of booston the 2.75" when I was expecting 9.5lbs on a 3" pulley. I have a 2.9" pulley comming from Allen Nelson that should do the trick.

With the Radix system we already have the intercooler so what more could be gained in a dropping the temperature further using an injection system (if at all) and how much more timing could we coax out of the engine?
I wonder if it is worth the effort?

 

Usually, the alky injection is used instead of an intercooler. I've not ever used one and am not really familiar with them. You can ask James B. about them though.

So ... to answer your question, I don't know how much you would benefit from the injection even though you're intercooled.

Did you get my PM?

 

Hello Guys, I need to clear this pulley problem up.
There is NOTHING wrong with the Pulley Boys pulleys. I received Boosted 6.0's pulley and belt today and after a quick examination , I discovered the problem. I have sold many, many pulleys to you guys and I have never had a problem or one complaint. Now to what caused the belt to tear. Simply, the pulley was put on backwards.
These pulleys are cnc machined and every pulley is made identical to each other.
From these pics you can see, where the nut scarred the pulley. In PIC1 , the left pulley is Boosted 6.0's 2.9" inch pulley, the scarring is on the backside. Notice the center spacer is shorter than the pulley on the right, that's because it's the backside of the pulley. In the same pic, you can see another Pulley Boy 3.25" pulley that has scarring on the front side.
Notice the center spacer is a lot taller and has a machined hex nut.
PIC2 shows the front side of Boosted 6.0's pulley and the back side of the 3.25" pulley, NOTICE there is no scarring from a nut.
For future reference, the taller center goes towards the front.

The ridges had nothing to do with the belt tearing, the pulley was installed incorrectly and the belt was riding on the guide, that's what tore the belt apart. Slipping? This is caused by installing a smaller pulley and using the stock belt or a worn/stretched belt or a worn tensioner.

Pulley Boys took a lot of time and research to get these pulleys perfect!

 

FarmTruc, any insight on the topic ??
