Sure, they are something you guys earned :-)

If you need any of them, let me know. I have a good state of cranks, rods, pistons, and even brand new cylinder head / valve train components that we have no use for.

After the engines come apart, its easy to see what the factory did to give some engines/ platforms more power than others, while using the same, or very similar components. Tossing those parts around and using the longer stroke factory crank combo, with the engines that have the larger bore sizes is something I first did with ease in 2010, while the 4.2 parts were being manufactured. Its not the route I wanted to go, because I want my engine, to truly be my engine, and the factory stuff doesn't fit my craziness well enough.

Like always, time tells the story. With the GT4 being so new, and having its own set of some of the components, everyone will have to wait and see what the results are as the years pass by. As you pull apart the engines it'll be interesting to see how our notes compare in regard to running clearances and how the visual inspections of some of the factory surfaces look. If you find anything odd, please contact me.

Its already "done it", I just want to make sure that it continues to "do it", as well as doing all the other things that its supposed to do while "doing it". LOL

The latest blocks will now allow for 4.4L, and I am taking one there now. I doubt I'd offer that engine, since the 4.2 has all the development into it so far, but it'll be nice to see when the intake, cylinder heads, and the rest of the platform become inefficient.

Are you doing any port work to the 4.0, or leaving it as cast with the GT4 heads? Its always nice to have a common cause, but a separate objective, thats how we can all live together in this small Porsche world, and have fun doing what we love to do. :-)

Really curious to understand the above comment - all of us are interested to learn how the GT4 is different than the 3.8 in the 911.

Overall this is really exciting to see development of the GT4 kicking off - it's going to be quite the hot rod. Cheap enough that I think we'll see people dropping a lot of money into the motors to chase it's big brother vs. the GT3.

It'll take a good while, and in depth research to determine that. Me, well thats not my main goal, because it doesn't matter to me what the differences are, since my ideas are so far removed from either of the stock engines. There are times when we find components are chosen for a specific purpose between two seemingly similar components/ engines, and that always is an interest when finding what piece needs to go into the puzzle. Flow bench data from the cylinder heads, and camshaft plots from my cam Dr. device have shown us some things that are the most interesting in regard to where the heart of the power band was intended to be. Doing overlays of those items in comparison with others carried out back to back sheds some light, but its not till the parts are tossed around and the engine runs, do we see how the things effect the engine most.

I think all of us that play this game already saw that from the very beginning. Thats why everyone I know that is a major player bought or got their hands on a GT4 and started development immediately. Thats something I haven't ever seen occur so quickly, or intensely with ANY water cooled Porsche.

I can verify the internals of the GT4 3.8 are the SAME components in the Carrera S 3.8

The case halves are obviously machined differently for the mid engine application but otherwise the same.

Flat6 Innovations

This is where we can compare notes and learn something from the two different perspectives. have you had those cams on a cam Dr, or are you going from part numbers/ casting numbers only? Same with the heads, had any on the flow bench compared to a 3.8 Carrera S?

They are not different. The kit will be available from either shop with installation ONLY at the respective shops. There will not be any dealers or remote installs. This was something where we collaborated to finally bring this project to fruition and if not for Rick, this thing would still be nothing more than a 3 year old pipe dream of mine. He was able to take the ball and run it into the end zone and now we have 3.99L in reality and not just on paper. I've been privy to everything the entire step of the way during implementation and tuning. It's the real deal.

Huge Props! To both BGB & DeMan.. It's rare to see such collaboration between shops within this industry!

Got to say it like it is!!

Thanks John!

This one is "gutted" and ready for a little magic, along with a billet deck plate, in an attempt to go to 4.4L.

Someone PM'd me and asked "why do you always take the hard road with these developments?".

My reply was "Why do you assume that I see two roads?"

Continued tuning to the ECU and other developments were dynod yesterday on our 4.0L engine package in our GT4. Attached is the latest dyno sheet. Testing short tube (red) vs long tube (green)header. 410HP and 345FT/LB at the wheels!
