HELLO!!!!
(IMG:http://www.aircooledtechnology.com/galleries/mshead/mshead03.jpg) Before you jump to conclusions, these ARE NOT the "New Generation" heads! These heads have 80+ hours of Len's labor in them. They started off life as a 1.8 OEM head! Now they are to be outfitted onto a 260HP, 8,500 RPM direct fired, EFI'd, Titanium rodded beast for an Aluminum bodied hand built 550 replica to be debuted at Leman in July! These are one of a kind, never to be duplicated, just like the engine they are fitted to. (IMG:http://www.aircooledtechnology.com/galleries/mshead/mshead01.jpg) (IMG:http://www.aircooledtechnology.com/galleries/mshead/mshead05.jpg) (IMG:http://www.aircooledtechnology.com/galleries/mshead/mshead07.jpg) (IMG:http://www.aircooledtechnology.com/galleries/mshead/mshead16.jpg) and here is the "Money shot"..... This is our newest exhaust port shape, and we already have special stub pipes made for it exclusively.. This is primarily to be used with Turbocharging. This changes all the rules. Len rocks! (IMG:http://www.aircooledtechnology.com/galleries/mshead/mshead12.jpg) Here are more pics in a gallery on my site. Mighty Gallery Yet again we raised the bar higher.... The sky is the limit. ***Valvetrain not pictured, proprietary!*** |

That combustion chamber reminds me of the concrete skateboard parks from the 70's-80's. Looks like a fun ride till you hit the drain (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

The actual coating composition is proprietary as I have 5 years of trial and error into it. It's applied by a company local to us that does a ton of work for NASCAR and they were willing to work with me to develop these profiles just for the TIV. These latest coatings I just perfected in mid 2005 and they work so damn well that it's amazing! You can tel a big difference when putting a coated and non coated head in the oven at the same time.. The coated head won't get as hot and it cools off almost twice as fast as the non coated head that was hotter when it came out of the oven. Coatings are not created equal. I melted pistons, lost rings and seized valves before we found what works and what don't with these engines and these coatings are limited only to my "Super Hero" engines and they certainly are not cheap! (4 pistons, a pair of heads and some DLC coated valvetrain cost us 1500 bucks to have coated!) |

Yep.. The twin plugs are "Period correct" for a 4 Cammer 550 and also allowed us to run 11:1 CR on pump gas!
The entire car looks like a 550, with every modern attribute.. The car is absolutely amazing and I can't wait to see how it goes over at Leman, Beth and I are going there for the Classic Leman in July to see! |

Yes, Porsche Post from the UK is doing a story and there is also a 30,000 word book being written on the entire vehicle build up.
The owner has come to document the build up twice in the past year- He brought me the core engine in a suitcase from the UK! This car is beyond the comprehension of most of the magazine journalist, they don't even appreciate it! |

What dizzy??
It's direct fire... Why waste all this leading edge work with an archaic dizzy! This project literally had no budget, but the customer got a REAL deal on the engine! |

Why should it last any shorter duration than any other TIV head?
The work we have done has strenghtened the heads, not weakened them. No material was removed from the head, material was added through pre heating and post cooling of the heads- the time consuming and correct manner of welding an aluminum head. Nothing I do is short lived, thats why it takes so long! This is a full time street engine, but it will see track time at Leman, Spa and Monaco.... |

I guess you're right, I guess I was thinking along the lines of heat and stress cracking, but since you're adding material and there was NO budget, thats probbaly already covered (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) b |

What heat??
This engine will more than likely run cooler than stock with the Thermal Dispersant coatings, Thermal barrier coatings, DTM, twin plugs and EFI..... AND the car is 1/2 the weight of a 914! HP doesn't make heat..... |

wow oh wow.
thats art. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) You should take it outside and take some pictures in the early morning light. You can see how the flow works. The turbulant areas, the transitions. so cool. |
