All,
I was wondering if anybody was doing true mechanical work-overs on the Heads. I have been searching the Net and I have not been able to find a Speed shop that would do High Performance work on MCS heads (i.e. Titanium Springs & Retainers and Sodium filled valves). Has anyone come across a shop that does this kind of work???? Or maybe you have done on your MCS that would like to share their experiences.

Cheers

There are several MINI owners that have done head work on their own.

The headwork was done by a local specialist who previously tuned Alfa Romeos. The ports were enlarged and polished and all that rough casting material was removed from around the valve guides, smoothing the airflow. Nothing other than polishing was done to the chambers so that we could retain compression ratios.

The guy that does it here in Dallas, referenced by Mckinneymini in his post, charges $895 to work on your head, I believe. Bigger valves are additional.

We are about 2 weeks out from the head install for our car. This hear has had over 25 hours of just testing and prototyping done on it. We are also working on larger valves that are being sized up right now. We will be producing a .5mm larger intake valve, and a 1mm larger exhaust valve. We are working with DPR Racing out of California, and we will be the sole distributor of the mini products from this alliance. DPR RAcing is in the front of Honda Development, and has been around for a super long time. We will be getting the flow bench testing done soon, and will be getting HP numbers once we install. We are also having work done on the supercharger that will bring it above the JCW specs even with a new lubricant on the supercharger rotors allowing for cooler operations and more HP at lower boost. Once done with all of these , we will be venturing into the Piston area. We are looking to get pistons made to match the clover shape of the head, and boost compression slightly. We are hoping for some major hp gains with the pistons and still be able to keep the car smog legal. If you want more information on what we are doing, please give me an e-mail at Mini@thepilo.com And we can discuss what ever you might need done.

Thanks,
Dan

I don't know if I'm coming or going... that might be to your advantage though john.... But withthe 30" breaker that hit your head, we may be even now :razz:

Will you sell lubricant refills as well?

This Lubricant is a coating that is being applied to the rotors of the supercharger This is a superlebricant that does not need to be reapplied, or refilled. Basically if you were to get this on your hands, you would not be able to wash it off, and would have to sand a layer off your hand to make it not slippery again.

Pilo,

This is exciting stuff. Please keep us informed. I am extremely interested in both the supercharger and the head work.

jazmini Jan 7, 2004 04:56 PM

Hey Dan,
Wow! heads, valves, pistons, etc. This is all good stuff for us future MC modders. Don't forget about us CVT types out here. Keep up the good work!

Dan please don't tell me that you are going to Teflon coat the supercharger impeler :eek: :eek:

MiniPilo Jan 7, 2004 06:02 PM

It is not a teflon Coating, but a high tech lubricant that will coat the existing coating, allowing for cooler operation, and a more efficient charge.

Thanks

I wonder if it's the stuff the sell in "ADULT PRODUCT" stores?
