No expense is being spared. We will determine the optimum lift to arrive at the optimum available hp for these heads. Once his has been determined the cams will be cleaned up to eliminate all harmonic distortion.

You can't really tell from the pics, but the valve "stem" diameters are not stock.

The actual seat/valve grinding was a very labor intensive job. Work had to proceed very slowly due to the hardness of the prototype coating used by HPC. The tools just wear out very fast with this material.

 

are u gonna be in a an upcoming episode i watch that show all the time... really cool show... what car willu be racing i definetely want to see this...

 

Now you can explore the inside of the intakes.

The intakes were ported/polished and then flow checked so as to obtain optimum flow.

Chad when will the beast live and the next best question will you be able to smoke all 4 tires and beat Craig in a race

marc

 

VRAlexander has seen KA's engine. Why don't you ask him that question. With our suspension and drive train we don't smoke tires. We connect all the ponies to the road.

As for completion ............. April.

 

so....mid september 2014 then?


just kidding CJV, i admire everything you have done this, and I have been following since about the time you bent all 6 rods.

Good luck, and Im sure once shes done, it will be everything you have wanted and more.

 

Craigger,

I probably ought to just finish her. We could have done so a long time ago. The trouble is one thing always leads to something else. Case in point is the heads. We were satisfied with the exhausts ............ then we learned the relation between the head flow amd hp. I was amazed that people don't even know what a stock head flows. Then I found out how some flow people play the same game as some dyno people. The numbers can sound great but how many inches of flow are they using to test and what is a realistic pressure. I have learned 25 psi is the number to use. There are values and formulas assocoated with this number that will accurately predict power output.

Another item is the cams. It took us three months to figure out what cams would work with the GT3 turbo motor setup. With the help of others and buying three different sets of cams we cracked this barrier only to discover that after all the cams we purchased we arrived at a solution but a new issue cropped up ............. harmonic distortion or in layman's having a cam that rams up smoothly in a turbo application. We are working on this now.

If the above isn't enough ................ while traveling throughout the world talking to all these interesting people, in the know, we happen to meet someone who has designed and manufactured some very interesting titanium rods for the 996tt that will sustain 1000+ hp @ 8200 rpm's with some longevity. These rods are very light, the cost about 1K per rod. These will be the fourth set of rods we have bought.

I just can't help but to wonder what else we are going to run across that will delay the final assembly. I just don't want to assemble this motor with any second thoughts or regrets.

 

Mike,

I have not been able to find anyone who has flowed stock 996tt heads. I just can't believe Porsche doesn't have this information available.

I'm not going to spend the money to find out as it won't help me out at all at this point. However, using the formula's and assuming a .8 bar boost producing 415 hp, I figure the stock 996tt intakes would flow approx. 142 cfm per cylinder at 25 psi.

 

Does anyone have a larger MAF that flows 27% more? Or for that matter just a larger MAF? No, the little Boxster retro doesn't qualify.

In the next two weeks we are going to be installing a few radical new parts.

 

as if what has been done already isn't considered radical this project is really awe-inspiring, the stuff automotive dreams are made of, and i look forward to each update! good luck with whatever you're working on and please continue to update us in detail, i think i speak for many when i say your developments do not go unappreciated. the heads and intakes look awesome. did you decide which turbos to go?
