Thread: Dyno time in Brisbane 100Tdi, exhaust advice .

With the exhaust remove the middle muffler and keep the rear as it will reduce the drone in the cabin...
That's all I can add

I have had mine on a dyno twice.......I wouldn't go back the the guys in sandgate.

If you are paying for a dyno than it makes sense to make adjustment at the time as they should be monitoring your exhaust gases that way you should get the best out of the car tune wise.......

I have just the standard pipe right the way through no mufflers....if I had my time over I would have left the resonator in place.

Second dyno was done near woolangabba by a guy I used to work with.......he just has a single axle dyno and knows his way around a diesel.....you just have to remove the front propshaft.

Brisbane Tuning and Turbo.......it's been a awhile but Bob or Rob as others call him will remember me as weeds.....he is the owner

If nothing else drop in for a chat

so full load on one set of wheels is not a problem?

Nope......both places just ran with the rear diff

It is a little scary when they get to 4th and start to load her up........I guess it no different than towing the trailer at 90 up a long hill

If you are concerned with drone, replace the middle muffler with a straight though unit instead of just pipe. (The standard mufflers look straight through with the pipe alignment, but are not, they do have baffle plates). You get the benefits of a straight pipe with some noise control. The one I used is a round 2.5" muffler, same as original length, which slips over the standard pipe and can be welded in place. Also left the rear resonator in place as its not causing any issues. I did notice that with the muffler swap the turbo (standard) does spool quicker with lower EGT's, so worth doing, especially with all the other things you are bolting on and have fitted already.

Thanks guys, I appreciate your advice, I'm interested in keeping the internal noise down, It make sit easier to talk to people in the car, I'm deaf in my left ear so excess noise makes it difficult to hear conversation while driving the car. ( can be handy if Madam is on a crusade) If I'm in the passenger seat it's not too bad. I'll fit a straight a through muffler for the first one and leave the tail pipe in. My EGTs have been ok I monitor them , mostly I rarey go above 550 deg C . I'm following the tuning advice that's been circulation around the internet for a number of years. I just do a small adjustment once in while and keep adjusting the power up. The VNTurbo will be a big step change. I think a big adjustment will be needed to get the most out of the new VN turbo. cheers simmo
