It seems like ITB's are all the rage with our air cooled sixes.
The throttle bodies are either PMO or direct to head either with butterflies or AT-Power with no butterflies. Mark dug up some of the pricing!! Thanks Mark!! X-Faktory uses Megasquirt, Link or Motec M84 https://www.x-faktory.com/uploads/6/3/9/3/6...efi_systems.pdf Starting at $4754 Clewett uses TEC https://www.clewett.com/index.php?main_page...dex&cPath=2 Starting at $8400 Rasant uses exclusively Motec, which is the most expensive https://rasantproducts.com/collections/mote...84-ecu-packages Starting at $5700 for the ITB's and $6200 for the EFI AT-Power offers throttle bodies without butterflies, but use special cams to optimize https://www.atpower.com/ Starting at $13K Lots of options which can raise or lower the price. I have a stock Euro 3.2 with DME that does run fine, but I miss the sound of the webers, but I don't miss the hassle of webers, cold start, poor gas mileage, etc. I know ITB's are expensive, but option 2 at X-Faktory is not that bad and pretty popular over on the Pelican 911 technical forum. Anybody on this forum have any experience with any of these toys? |

James Patrick pitched this to me last month with a price around 6k. While it sounded nice I just didn’t want to mess with a system that’s not broke.

James Patrick pitched this to me last month with a price around 6k. While it sounded nice I just didn’t want to mess with a system that’s not broke. 6k installed? I doubt it. I have to agree, $6K is the price for the entry level PMS ITB's alone, not including the EFI system. To me the prices of the 911 ITB's are crazy money. I'd be buying a pair Triumph triples. https://patrickmotorsports.com/collections/...njection-system I'm building a 964 plenum based EFI system, I'm aiming to do it for under $1500....Canadian. (IMG:style_emoticons/default/biggrin.gif) Below is my T4 motorcycle TB build, not counting build time I have no more than $200 into them. http://www.914world.com/bbs2/index.php?sho...p;#entry1862152 |
