Slow up hills

Post by Striker on Wed May 06, 2015 8:03 pm

I have a 1997 Executive with a 2.5 Diesel engine, it is fine on the flat but really struggles when on long inclines or hills, any suggestions as to how to improve the performance?

We had one of these fitted to our 2.8 HDi to help shift the torque so it didn't pop out of our (retrofit) cruise control due to the revs dropping on long inclines (not steep hills) on motorway:

www.tunit.co.uk

They have a 0-9 adjustment which can be used to maximise torque where required across the revs. There's a page on the website where you can input your exact engine details to see if it is suitable.

I think you have experienced what most 2.5 non turbo drivers find. Certainly my 1995 Executive was slow on long inclines as well as most other times as well. I soon came to accept that this was the way of the world and lifted my foot slightly to ease the stress on the engine then enjoyed the view ahead.

Yep, sounds about right, I struggled with this as well when I first had mine, especially as I had 2 relatively powerful cars & bikes, BUT, I soon got used to it & now drive accordingly, 'wiggling' the stick when encountering hills is now the norm, & it seems to thrive on revving its nuts off. hugegrins 
A pal who is an auto-engineer & knows Peugeot diesels well, informed me that its actually the best engine, stress-wise,  & although not a performer, its just about bullet-proof.
A lot simpler as well.
Tunit  & similar won't works & there is no turbo or ecu so nothing to plug one into & therefore 'adjust'.
So us basic diesel campers are lumbered with wot we got.!!!

We have a 2.5 non turbo and fully agree with the above comments, get used to it.  hugegrins hugegrins hugegrins

I have a pal who sells old vans for a living (and has to take the hit if they break), and he also says that the 2.5 is an unburstable engine.

Enjoy the pros of having a very simple and reliable engine, and live with the cons.

Does yours have a catalytic converter, no? Then no-one can nick it.  hugegrins hugegrins hugegrins

Great engine capable of huge mileage much more than a motorhome will ever do, mines in a symphony so a bit lighter and more aerodynamic than exec', although not the fastest thing on the road it will keep up with traffic ok.
On a motorway I usually keep it at just under 60mph,it seems to have a "sweet spot" at whatever that rpm is and runs like a turbine, always get 30+ mpg.
You might get a slight performance improvement with a K+N air filter, I haven't got one because I'm too tight fisted to pay £50 for one, but they never need replacing.

Hi there,

Commercial vans run empty for half of their life and are very seldom filled to capacity .... wave wave

.... whereas the fixtures and fittings of a motorhome bring the weight up to just below the legal maximum .... up! up!

.... with a few kilos left for the owner to put in a pair of swimming trunks and a change of socks. Whistle1 Whistle1

If your van is "sluggish on hills" I suggest that you just relax, drop your expectations and enjoy the view!!  allthumbz allthumbz

Best regards,
