Fuel usage

[shortSteve]

Hi ShortSteve, thanks for that, the more I learn the less people went with 3". Was there a specific reason you went with 2.75"? I like the fact it is not very noisey as I dont really want that. Did you notice any more power/torque when towing, or just lower temps?

Thanks

I initially went with the Beaudesert 2.75 on the triton after hearing of multiple overboost issues with straight through 3 in systems. In hindsight tho it seems more to be specific vehicle problems than just a cause of the exhaust size. But, I was happy with the price, service and longevity of the system on the Triton, so ordered one for the Challenger to fit as soon as the car arrived. Fitted it after the first service so I could compare before and after fitment.
On the manual triton (which doesn't develop reasonable boost until 1800rpm+) it was maybe a lil less torquey to get moving, but revved so much quicker through the rev range. Economy improved very slightly but overtaking power was noticeably better. In the auto Challenger, I never noticed any dip in low rev performance, most likely masked by the transmission, but foot down and revving out was again noticeably improved. Due to early stage of fitment a fair comment on fuel usage wasn't possible.

Thanks shortsteve. That is what I am being told as well by the exhaust shops that it is more vehicle specific. They have also said that if you have an ECU tune the tuner can program it so there are no overboost issues.

My Triton was ecu tuned and had around 25psi max boost, 500nm and 200hp iirc (dyno's all read different so don't expect these figures to mean much, but was significantly faster and way more torque, could just side step the clutch and pull from idle, or 1200rpm with the 2T caravan). The challenger usually sits around 23psi max. Used to be 19-21 max but now has a very mild chip that only operates on high throttle % (is wired into the accelerator pedal aswell as injectors/map line). Only really changes tune above 3200-3500 rpm.

Feeling like a play on the way to work this morning.

Pulled out onto the main arterial road, "The Central Coast Hwy" at Wamberal.
Kept it in sports mode with the torque convertor locked. Easy to do at 4 in the am.

Played with the paddles, never touched 5th. Watched the display go down through 10pkh, down to 9.2pkh.

Then got to work, and had to go collect a trailer portapotty because the 50 peeps on site had no ability to flush the good ol #2's due to a burst main.

Interesting driving a trailer portapotty with water in it. Handles far worse than a Cat1 fire tanker with a partially filled tank.
