We'll look into 9's next season
But yeah if you go to magnus' site they released a new race spec manifold. Here is the quote from the website, actually the only info I have found is on the home page and scroll down to May 10th when it was released:
Our standard manifold has become the industry standard, Proving to make over 40hp to the wheels on street cars and race cars alike. Our Race Machines have been testing these desings for the last few seasons. Now we have brought our custom one off pieces to production. This style intake was designed for the high revving motors that spend the better part of their time above the 8000 RPM range. Variations of the Race manifold have tested to be able to improve engine breathing up to 10,500 RPM. The Race Intake features our original CNC velocity stack design and spherical endcaps. It makes better use of the plenum size and air distribution, by feeding all 4 runners AT ONCE from the bottom of the intake, along the entire length of the plenum.
Haven't heard of anyone other than Marco himself running it?
And as far as my head goes, stock in terms of porting, which will be changing over the winter. Crower valve springs, retainers, and most importantly 64415 Race Spec cams. I finally get to see this 2.4 make some power over 7000 rpms!
Look for some results October 22nd at Cedar Falls...
