XP-IO-360 vertical draft install references?
Hi Guys,
I am looking for people and reference websites that have successfuly installed a XP-IO-360 vertical draft FI in a RV7 or RV9. I am currently busy with mine and are constantly running into small items I wish I could see how others have resolved it. Thank you in advance. Kind Regards. Rudi |
Good morning, Rudi.
My -7A has the same engine with the SilverHawk EX FI system. The biggest problems I've had so far are: * The mixture arm swings downward which interferes with the airbox. I didn't know it at the time, but Precision Airmotive sells a servo with the arm reversed which eliminates this problem. You can't simply rotate the arm 180 degrees on the servo because the throw will be in the wrong direction. I know that some folks, including Scott Will have used a quadrant instead of venier cables which apparently eliminates this problem. I am modifying the FAB with a cutout to allow the mixture arm to swing downward. * Prop Governor -- If you're installing a C/S prop and using the Van's-provided governor you'll need to rotate the arm around. This isn't specific for the XP-360 though as I believe pretty much everyone has to do this these days. * Oil Output Fitting for the oil cooler. All I can say is holy #$%@! I spent more than two hours last night putting this thing on (45 degree fitting). I had to pull the right mag to do it. I'll need to recheck my timing before first engine start -- oh well. I would recommend people install this fitting before they hang the engine if they can. Better yet...I would call your engine builder and ask them if they can install it for you before they mount all of the accessories. * Metered fuel line (servo to flow divider hose) has to go through the rear baffles and is close to the oil cooler if you're mounting the cooler on the baffles. I did put my cooler on the baffles and I think I can get the hose through there but it's going to be a challenge. I don't know if the Superior-supplied hose is going to work. You can check out my stuff at my website (see signature). Please keep in touch. I have a LOT of questions myself about this stuff. |
Hi Jamie Thanks,
Luckily got th right Fuel Servo with to correct arm, but then the XP supplied fuel hose don't fit from pump to servo. So I had one made up. I see the supplied hose from servo to FI spyder currently fits, but will see when I fit the oil cooler and baffles. I hope I don't have to make another hose. PS: Keep in touch, let me know what you find as you go along. Any other refernces please add below. Kind Regards Rudi |
Nothing to add except..
I have the SJ cowl, otherwise the same. I left the oil filter straight 90 degrees to engine. Write for phone number if you like; I'm retired and can take daytime calls.

Perhaps some-one can refer me to an RV website. I'm very interested in this but I can't tell if it's a good idea or not. |

My TMX-I/O360 has the Silverhawk and to cure the problem of the arm hitting the FAB I made a 1" spacer using a commercial grade cutting board that is chemical & heat resistant. It goes between the bottom of the throttle body and the FAB and will give the clearance needed for the mixture arm. Simple and took only an hour to make.
I'll post some pics over the weekend if anyone is interested. |
