For you, Britain... We'll be talking more about these on 4th Dimension Radio tonight (Thursday 17 August)!!!www.aircooledtechnology.com/radio Listen in for more info!! Here they are! Len has done a TON of work on these heads and they have even more flow potential left in them! These are 42X40 with the new "Turbo seal" exhaust port and matching stainless steel stubbies. This unique port was adopted from the Mighty Spyder project and it works like crazy!! BTW-We WILL be working with these heads on several N/A engines as well, of course with different chamber shapes and port flow margins. This would be an awesome head for 2.4-2.6L daily driver engine that needs serious grunt!! I told you that 2006 was going to be a serious Turbo development year!! Its not over yet!!!

The bar just got raised higher. BTW- twin plugging is optional! |

You'd be suprised at what works and what looks like it would work but doesn't..
We have seen heads with huge ports that didn't flow as well as stock and had grossly worse air speed- thus making less power and being a bitch to drive. Its not the size of the port, its the shape and the size and the portions of the port that are worked the most. These prototypes of the LE 220 have about 4 solid months in their design.. Its a matter of trial and error with silicone pours being made along the way to model the port and see deficiencies.. Bigger isn't better especially if you sacrifice velocity in the process. |
