Orion number 5 or number 6 horizon has them

The WC edition 5 port is going to make a lot of power, no doubt about that, but you can also use the smaller venturi insert, lower the EPA, and get stupid good mileage too. There are advantages to having an engine that makes a ridiculous amount of power, you can choke them down more. :nod:

seems to have a big window on the bottom, 1/2 turn or so from too rich to too lean. they like 250's if you temp at all.

Engine finally broke in this weekend at the Missouri State Series opener in Jeff City.. Even though it finally brok-in it never seemed to get doggy like a lot of engines I've seen when they break-in.. This engine just dropped temp from about 245 ish down to 170 after 8 minutes of running.. I leaned the bottom out to get the idle back a bit, and lef the top in alone, and it was dialed for that tight in-door track.. I'll get a proper race tune on it before the next race, and report back, but I know it is going to be of the hook.. I'll be getting one of these for my Buggy, no doubt about it..

FYI I am running the 5-port discovery with 2013 pipe in a truggy..

The #5 or #6 as mentioned, but an O'Donnell 97 works nicely also.. FYI I don't think your friend will be as happy with that pipe as he might be with a 2013 or 2058..

It also likes the jp3 :nod: o'ddonnell 97 :nod: discovery 5 port:nod:

Hey Guys. If you haven't seen this, there is a contest on Facebook to win a limited edition King engine/pipe combo. All you have to do is answer 3 questions and you could win. Pretty cool.

If you click on "View in Detail" there is a cool interactive page that you can check everything out that comes in the bag with the engine.

I'll give you a hint and say the brushless system is Vortex R8 Pro, and I'm pretty sure the engine part number is ORI80681, but your guess is as good as mine on the number of fans on the Orion page. :lol: good luck...

I have a JP3, but I cannot imagine that it is better then the 2013, as the 2013 rocks..

Never said better ,but it feels really good.YES that 2013 pipe is the bomb:nod:

I am rebuilding a Orion Alpha 7 port for a guy, the rods are $80.00? Any other cheaper options?

werks b5 b6 rod works great.have one in my mte.

Sirio rods from the CL7B STI will work aswell if i'm not mistaken.

I've had a Werks B7 and 2 sirio Evo IV's and the rods would not interchange on them at all.. The werks had a much smaller crank pin.. Whether the Werks B5/B6 are the same sized rods as the Orions I do not know.. If you are considering buying an off brand rod consider the Nvision, as they are really really cheap..

Don't know about Werks but i'm fairly certain one can replace Orion conrod partnumber ORI81839 with Sirio Rod partnumber S21.070012 (STI racing conrod) or S21.070010 (racing conrod)

have a b5,b6,b7,trinity extech and an orion mte.all 5 rods will interchange.have taken them apart many times and the rods are the same.as for a sirio i dont have imput on that as i dont own one.for the price my extech and mte both have werks rod.hope that helps.
