Thanks for the info Ken.Sounds like you have hit on a good system. I will have to have a look at something similar. I think for my initial engine runs etc I will just use a simple pipe settup, hopefully progressing to a muffler design down the track. My missus dosn't even want me flying this thing so sneaking out the back and blasting off in stealth mode is a great idea.

Ken, did you make the muffler or buy it and if you bought it, what make is it etc ? Sounds pretty straightforward and should be reasonably light !Brian

G'day Brian & co. The muffler was on the machine when I bought it but it has been fabricated. The easiest thing to do would be to buy an inline muffler, cut one end off and gut the inside and weld the plate in,and the tailpipe on the end you cut off before welding it back on. I used the 2-1 off the standard headers which Tim would have used on your pipe. Performance is the same if not better and it is not much heavier. It only took me about an hour to weld it up and fit. Will try and post a photo, or email it to you. Brian, keep an eye on the idler belt pulleys. I replaced a crank front seal the other day and all the idlers were dodgy but the tension pulley was shagged. Complete kit with belt was $400 and something from Repco.Ken What's your email?

Hello GentsDoes anyone have any information on the oxy sensor input modes, On other auto systems the oxy sensor is only used in the lower power settings from idle to nearly cruising 60 kph. my sugestion is that the o2 sensor may be able to be disabled and omitted, any comments from those with some experience on the Subaru system.cheersGGGyro Gearloose

Posably Alex BUT if the ECU goes into fault mode while it is @ below 13% at the TPS it will remain there so it would be wait & see & the see part may suck with very low power in limp home mode Butch

Hi Alex,I could be wrong, but I believe the ECU requires the sensor input regardless of whether it is being used or not. If you want to continue to use the Check Engine Light in your system them you need to either have the sensors connected or trick the ECU into believeing they are there.Like I said though, I could be wrong....Paul

The O2 sensor delivers a voltage to the ECU, it can be tricked by using a voltage source and a regulator to operate it within a particular range, if you used a variable resistor on the dash you may be able to tweak the engine to work rich or lean depending on how you want it to run, preferably rich.It is of course far better to have the thing working properly to ensure the engine runs as best possible.

Hi Ken, I noticed a slight oil leak at the front of the motor coming out of the cam belt cover so will check the idler pulleys as well !!! Thanks. Email is eulo2@bigpond.comTim replaced the belt about a year ago and everything looked fine then.Brian
