NEW PARTS-Valves& Springs

[MP3racer]

Hey everyone,

All of us at Doc B Racing have been working hard on the motor and chasssis build of the Mazdaspeed Protege Gran-Am Cup race car. We have developed several new parts for the motor. One of the first we think we will have available for sale will be the upgraded valve train components. Anyone who has forced induction will benefit from better valve springs to keep the valve open in the face of the increased cylinder pressures. Also the upgraded stainless steel valves will withstand the higher cylinder temperatures seen in turbo charged engines.

I wanted to guage the interest of these parts. The valve springs are a special set we have developed with Eibach. (Yes the same eibach that makes the world renowned suspension springs). The valves are from another well known manufacturer, Manley. I should have pricing on the kit in the next few days.

We will have other components available once we have tested them to our satisfaction.

Take Care,
Tom
Doc B Racing

Hi Tom,

Good to hear. Just a few questions for you:

What is the maximum cam lift the valve spring can handle before coil bind occurs?

What is the maximum RPM the valve spring can maintain before valve float occurs?

Is your company going to be developing titanuim retainers as well?

Thanks.

Javo: Yes, these will work great for N/A as well

Shawn: I will get the specs for you tomarrow...I have them at the shop. At this time we are not going to develop the titanium retainers since they are not allowed in GAC. We have a source for them. If there is enough interest we can do it.

I AM INTERESTED!!! I have been trying to spec out some valve springs for a long time but every manufature related that I would have to make a minimum order of about 500 springs..... Just a little bit more then I would need. Hehehe! Prices would be nice and can the valves be ordered 1mm over? Just wondering.

You would be the sole providers of valves and springs, and thereofre, would get lots of business if the price is reasonable, I guarantee it.
