Remaps, Intercoolers, other mods and a dead EGR.

[newhue]

Ok it seems the old EGR has hit it's 45K run life and died again. This has been my experience. $800 is the repair bill so a remap to shut it up forever is cheaper, and hopefully more reliable.
Now with all the excitement of possibly pulling 120KN and 450Nb out of the little old 2.4Tdci, I'm trying to filter the marketing form the reality. I am not sure if I need every mod to get 120Kn, but I also don't need it either. The list of mods can add up with de cat pipes, silicone hoses, bigger intercoolers, removing mufflers......
I do accept it all makes a difference, but having paid $1200 for a 5% gain with an exhaust in another life, I don't feel the need to do it again.

I've been advised by a UK tuner, that living here in the wide brown land an intercooler is a good investment regardless of if a tune is added or not.

I have been directed to an Alisport $830Au intercooler. I see Paddocks sell $504Au version with similar size, welding, and specs. Has anyone had experience with either. Are they simple to fit or a bit of a pig. I'm not all that excited about one mod creating another. I'm happy to do just the map really, but if a cooler is easily to fit and has some benefit like more that 5%, it may be plausible.

I've also been advised, if my hoses are old then it's worth replacing with Silicone, but until then no need. Is 95K old, or perishing crack = old.

experiences please....

I've got the BAS remap, alli intercooler and Nuggets air box mods - all of which are money well spent and have netted a significant (understatement) gain with no additional cost (possibly a small saving) at the pump.

Currently playing with the exhaust (which I'm led to believe is the least restrictive part of the 2.4) - I've pulled the resonator and replaced the main muffler with a hi flow. Which appears to have achieved very little, leading me to conclude that the cat is where the gains (if any) are to be had. Currently toying with the idea of a full 3 inch system with hi flow cat but the $$$ is a little off putting (to say the least).

I've got a BAS remap, Alisport intercooler and the cat's innards have been drilled out.

In order of mods:

1. BAS remap: as amazing as the original BAS remap was, the version2 map is even better.
results: increase in performance, decrease in fuel consumption, decrease in EGTs

2. Alisport intercooler
results: even more increase in performance, further decrease in EGTs

3. Removing cat's internals
results: a bit more oomph at low revs, reduced turbo lag and a further decrease in EGTs


In real terms, this is what the sum of the mods amounts to: at the Atlantis dunes, where other Pumas are climbing dunes in 3rd/4th Low, I am doing in in 2nd High without any issues or high EGTs

Thanks for the honesty. Some cars seem to respond to various mods differently I think. A mates patrol did well with an exhaust, but my rodeo did zip. The puma already has a 2.75mm exhaust, so I doubt there will be much gain in a 3".

What % do you think the intercoller did. I'd imaging the tune delivers most of the gain, the add on just top it up. It certinally was the case with the old rodeo.

Yep, the tune is the big gain - the intercooler (plus silicon hoses) is seat of the pants noticeable but not night and day. If I had to describe it I'd say tgat the intercooler is worth about the same amount as a hot vs cold day on the standard engine ie things are running better, but it's still the same engine. Tune makes it feel like you've done an engine conversion!

Don't neglect the air intake though - its definitely the best bang for buck improvement - almost as good as the intercooler at substantially less cost.

I have sent out a feeler for freight on an intercooler so see what transpires.
It does make sense have to admit, as it all does, but extracting every bit of power is not the priority. To be honest I'm still in two minds if by pulling more Kw from the motor compromises longevity. LR in Defenders anyway, have stuck close to 90Kw and 360Nm right through the model range over the past 30 years. Weather it's drive line limitations, or what they feel is a good compromise I haven't been able to work out. They sure have copped some stick and lost sales from sticking to the smaller power range.

Oddly enough I replaced my 33's with some city 32's today. And for the initial drive to work noticed the change in holding itself better on reasonably steep hills, and a bit more spritely. I'd liken it to the exhaust I once did. Not amazing but noticeable in a small way, but certainly not worth $1200.

If a cooler can do the same and be landed for half than most likely will go with that. The rest is a bit to refined for me I think.
What ever I do I should move pretty quickly I think. LR won't admit a buggerd EGR valve plays with economy. But the last time it happened I was only getting 300klm on some tanks. With the xmas expedition to just about start it's going to hurt at that.

Having sold all these bits and bobs in a former life, this are the best bang for buck bits. Noting that I have no experience with Nugets air-box mods so can't comment one way or another.

1. BAS Remap - I'd personally only get a BAS one
2. Allisport intercooler (they fit!!)
3. Decat front pipe.
4. EGR removal kit

Unless your hoses are stuffed, there is nothing to be had by changing them.

and Nuggets air box mods -

Mate, can you provide some more details on this mod please?

[Samblers]

Ive got no idea about remaps but reading with interest (prob get even more interested when EGR valve dies)

Is a BAS remap specific to an individual car? What stops someone borrowing the kit from another puma owner?

Yep, the map is VIN-coded.
