Real world fuel differences with blower

[daves8]

I am contemplating a 2300 / 2650 blower for my L77 and was hoping those that have done this can give some commentary around fuel usage?

I appreciate there will be massive increases when into it, but was more interested in the differences when driving sedately with traffic (1500-2000 rpm, 60-80kms etc)

the blower would only being delivering low boost at these revs I assume, so wondering what the fuel usage is like?

cheers

I've had my Harrop 2300 on my VFS1 Calais for 6 weeks now.

At idle, it now consumes 4.1 L/H compared to 2.1L/H before.

In Sydney traffic, the fuel usage is high. The last 50kms, I've been getting about 19L per 100km. After a fill of BP Ultimate, I'm seeing a distance to empty of about 320km around town. Bottom line is it guzzles fuel around town.

On the highway, I'm getting about 11.5L/100km average with of best of 8.1L/100.

Thanks, that feedback is perfect.

is the trade off worth it mate?

You've gotta pay to play. The poor fuel economy isn't an issue for me (yet). I drive less than 10,000ks per year and many of those are road trips.

It's still a novelty for me. I love the power and acceleration. It's addictive and, at times, scary too. I've wanted a blown V8 for a long time, so yes it is worth it.

I've already booked in for next round of mods in a couple of weeks. More boost and diff gears.

I am tossing up wether to spend to 20k on my Calais V, or sell it and buy a ML63, which will be a 20-25k changeover.
I miss being in a 4wd since selling my keep SRT, but the Calais is so reliable

The blown Calais will “reliably” use a heap of 98

Those ML63's look like nice rides. Twin turbo V8 and 4WD to get the 386-410kW power to the ground. AMG tweaks already done.

Yep stock 0-100 is 4.8 seconds, but with a tune only another 100 kw and 230 nm torque. Doesn’t need any other mods.

Yeah, but it's a truck.
Hilux costs waaay less, and is identical in pretty much every way.

Now C63, that's a different kettle of fish ... unfortunately I'm not in a bikie gang selling meth to school kids, so I'm not allowed to have one.
