Rusty.....my intake runners are also 30 inches, = just like=20 the Powersport engine and the Mistral rotary engine. I am = considering=20 relocating the injectors to the first bend of the intake tubing, closer = to the=20 engine, primarily to stop the few drops of fuel that drip out of the=20 throttlebody just after engine shutdown. (The throttlebody runss = downhill for=20 cowling clearance). My idle is great. I don't know about throttle = response=20 because I don't have the prop on it yet. Without the prop, I now = have it=20 idling smoothly at 1000 rpm. I'm thinking that a prop will act as = a=20 flywheel and possibly give me an even lower idle?

Here is a link that sells = weld-on=20 injector bosses and fuel rails. www.ptrsds.com/manifolds%= 20.htm =20 They will also take your manifold and add the injector bosses and = fabricate a=20 custom fuel rail if you want to spend money. Take care. Paul = Conner,=20 thinking about spending money.

Really? 30 inch runners? I knew they were long but that's = just way=20 too long. I don't think injector relocation will fix power but = it should=20 do wonders for idle, low throttle tuning & throttle = response.

Subject: [FlyRotary] injector = relocation predictions?

Greetings,

As I = mentioned before,=20 one of the relatively easy options for improvement will be to move = the 4=20 injectors, and keep the current intake. As they are now, all 4 = injectors are in the TB, which is 30 inches away on the cold = side of=20 the engine. I believe I can mount the two stock primaries back = in the=20 block, and can probably mount the two secondaries in the intake, = maybe 2=20 inches from the engine.

Here's the = question, do=20 you think this will increase power? In other words, am I = losing power=20 by having the injectors coating the inside of the long tubing, = rather than=20 efficiently delivering the fuel to the=20 engine?

Thanks,

Rusty = (thinking of=20 draining one fuel tank, and filling it with helium to improve=20 = climb)
