Is it just a lump of rubber to take a bit of the shock out if you’re off roading ?

It’s the collapsible section for a front end collision.

It’s pretty stiff but probably gives a little damping like you say.

Dave!

Aha. I was scratching my head over that too.

I see, the shafts are cranked to make room for the damper bit, the ends are in a straight line with each other.

It’s tech like that which makes it the safest 4x4 in the world

Remains to be seen whether it's a boost leak or the turbo itself on the way out

diverter ?

sounds like something cheap but tricky to pin down

That's my first thought as the hiss sounds very similar to part of the dump valve sound and comes from the same sort of area.

Need to do a bit of testing because they're about £90. If they were £20 I'd just bung a new one on.

It sounds like the turbos fucked. Time to fix it with a bigger one

Dump valve / diverted valve was hanging off.

Tightened the bolts and its fine again. If anything it actually feels perkier than it has for a ages. I thought I was just getting used to / bored of it but maybe it's had a slight boost leak for a while

Somewhere, JL suddenly felt a warm glow and had a smile at that post.

Dave!

On the positive side, no new turbo needed.

On the negative side, no new bigger uprated new turbo needed

Boost leak identified on the Loltus, crack in the chargecooler!

Need to get it on the dyno and see what’s whatbas it’s still running rich.

Also been sniffing around various more endurance based series which would involve the car going to Naturally aspirated. Will see what 2020 brings

It’s been a year since I bought this and honestly thought it would be a 6 month flip on the way to a Cayenne Turbo S but it’s been so good I’ve bought new wheels for it, new tyres, gearbox oil changed, new brakes all round, had the air con fixed along with lowering it and finally remapping it.

Enough to say I’ve really grown to like it even if it only did 22mpg around town, 27 on a run and was the top tax band. Remap has helped massively with the fuel economy, it now does a more respectable 29mpg around town.

Looks great What wheels are they?

Not that it matters to me, but out of interest, is that 22 => 29 mpg round town improvement based on trip computer info or measured?

Trip computer

If the computer is taking a reading from a flow meter you should be good. Often they assume Xrpm and Ythrottle opening = Z flow rate. So the above scenario may have delivered 1cc (per second or whatevs) of fuel on the std map, but the remap squirts in 1.2cc, which results in a reported mpg improvement.

I don’t know what system is in the ToeRag, but a 32% improvement in mpg seems unlikely (?)

Yet the range doesn’t lie and that’s definitely increased.

My dad has the same improvement after remapping his X5, went from 400 miles to a tank to 500.
