Well?



Any Guesses ;-)

 

A sprinkler head from Home Depot? $2.99 each in Gardening, isle 28?

 

An extremely blurry pic ?


Peace,
D

 

injectors

 

if we win, do we get a free sticker?

 

Hmm... Sure

 

did i win? lol

 

spark plug tubes

 

Intake/exhaust valve seals?

 

An entire civilization of beings fashioned of nothing more than a steel bolt with rubber surrounds and some Locktite? . Not it? DAMN. Oh well, how about new bolts for your crank pulley?? Or, some new valve thingys.

 

Very Good!

Pilo Racing Announces the first EVER! Mini Cooper High Performance Valve Seals. Pilo Racing and DPR Racing do it again, The innovators in the Mini Cooper Performance Engine products, we have the first and the best Valve Seals. They work in the most extreme conditions, Both Cold Weather and Extreme heat from Racing. For a little inexpensive part the valve stem has a different and challenging task. They are often overlooked as an important part of building an engine. They also fail causing expensive damage and or repairs.

 

I'll take some of them, some new injectors, schrick cam, Throttle body, header ...

And a MECHANIC to install them all

Where are the MECHANICS ????

 

What is the problem with the stock design?

 

I haven't heard of any failures, but apparently the stock ones have the opposite characteristics of these:

 

It's all a matter of the Material used. The temperatures that they can withstand, and the abuse that they can take.

We have increase (or decreased depending on direction) the maximum and minimum temperatures that the material can handle, It is also able to withstand more wear even at higher RPM's then the stock material.

From now on, these are the only seals that DPR will be using on any Cylinder head project that we have. We are also the only ones that have these available for our projects. So you have to think that if you are going to be racing, or driving hard in the heat, and want to upgrade your cylinder head, why not use a FAR superior product that we include at no extra cost to you.

 

I'm not knocking the product or accusing you of anything, but I'm curious how you tested the stock parts to determine the operational temp ranges and measured wear? If there aren't any reported failures, why fix what isn't broken, right?

 

You have to be careful with the wording that you choose. Opposite is not the word that should be used.

The Stock Material used in the valve seals by the nature of the material used, are less resistant to extreme temperatures in both directions.

The material we use has the property to stay within operating conditions at both higher and lower temperatures. It also has better wear charecteristics compared to the stock material. This will help it in race applications with higher sustained RPM's at higher temperatures. DPR has been using this material on all of thier Seals that they Manufacture and install on all makes of cars. They have gone to this because they HAVE experienced a failure on many stock brand seals on many diffrent brand cars. We have gone the extra step to manufacture our own seals for use in our High Performance Mini Cooper Cylinder head upgrades.

Let me know if this answers you questions Andy.

The information that we are using is Known from the Materials Properties.



Valve stem seals basically utilize 3 materials: Nitrile, known as NBR, Polyacrylate, known as ACM (or just AC), and Fluoro Elastmer, known as Viton. Usually Stock Seals are made of NBR or ACM. Below are some advantages and disadvantages of the various valve stem seals. For a little inexpensive part the valve stem has a different and challenging task. They are often overlooked as an important part of building an engine. They also fail causing expensive damage and or repairs.

Nitrile (NBR)

Advantages

• Low cost, readily available, and plentiful. Mostly manufactured in China.
• Good low swell characteristics. Good in extremely low temperatures, and low operating temperatures.
• Inexpensive to manufacture in ½ the time and with inexpensive materials.

Disadvantages

• Compounds tend to permanently harden during high operating temperatures causing them to fail. They do not recover.
• Easily damaged by additives, race fluids, and long shelf storage.
• Short Life

Polyacrylate (ACM or AC)

Advantages

• Resistant to EP additives
• Handles high temperature better than nitrile.
• Low swell characteristics, allowing Nitrile to maintain a better seal.

Disadvantages

• Does not survive or perform well in cold weather conditions
• Poor dry running characteristics.
• Much higher production and retail cost than Nitrile. Unfortunately many believe it is much higher quality than the “cheapy” seals.

Fluoro Elastmer (Viton) <---Pilo Racing Seals

Advantages

• Excellent high temperature capabilities.
• Compatible with typical race fuels and additives.
• This is the best compound to hold a seal through extreme conditions from freezing to overheating.
• Long lift, great sealing capabilities.

Disadvantages

• Along with being the best, the material is many times the cost of the other seals.

The superior material is very expensive. The production cost is dramatically increased. Fortunately the overall cost for this quality is very low.[font=Times New Roman][size=3][/size][/font]

 

They will run $45.00 Per Set. They are actually cheaper then MSRP of $46.25 for stock seals from MINI.

 

Thanks for the info. Are the stock MINI seals made from NBR or ACM?

 

So what do I win?

 

PM me your Address, and I'll stick some Decals in the mail :-)

 

We are getting a Chemical Report of the stock seals to get a definative answer.

 

But you know for sure they are not already viton, right?
