Why BAS over Allisport?

The B.A.S. fits straight in. The Allisport requires some slight modification to the radiator mounting brackets. Also, by all accounts, the B.A.S. is a more effective unit, but I don't have any experience to be unequivocal on the subject.

Been driving mine like I stole it on every drive for the past couple of years! (w/- 170 with Allisport IC - BAS IC wasn’t available back then). It’s my daily driver, as well as doing hard slogs in the jungle, and high speed highway runs from KL to Singapore, or KL to Penang.

Have ashcroft ATBs in front and rear diffs. Figured if ever the transfer case needed work I’d toss in the Ashcroft centre diff ATB.

But after years of flogging the vehicle hard the transfer case hasn’t needed any attention.

So far as priorities go - it’s not likely the BAS 170 tune that will kill the centre diff. (You can kill the centre diff yourself in seconds in stock tune - just leave it unlocked and do some serious wheel spinning.)

if if you run the 170 tune without the larger IC you are courting trouble. Set up the BAS tool for live monitoring. Particularly monitor intake ambient air temp and air temp after the intercooler (air temp going into engine). In standard tune, or 150 tune, with stock IC, regardless how hard or long you sustain full throttle, the air temp after IC will be close to ambient. (My actual experience).

With stock IC and 170 tune - after a minute of working hard (loud pedal to the floor) the air temp after the IC shoots way up!
(of course with the larger IC air temp after IC is always close to ambient)

We were over 5t inc camper trailer and only had one little issue with it getting hot (not really sure why and it hasn't happened again.) We were climbing up out of Cairns over the mountains and the needle hovered at the nerve wracking point for a short time. It was very hot and humid but it was pretty warm going up the Cape and through the Gulf country too.

if the needle you are referring to is the Land Rover temp gauge in the dash then she was really hot. I have an ultra gauge which gets its information from the ECU, and I have seen coolant temps of 112C on the ultra gauge and the temp needle on the dash hasn't moved from its usual just under half, coolant temps vary between 85 and 106 depending on the load on the engine. Towing the camper guarantees around 2C increase at least on my MY12 90 with Allisport intercooler and BAS 170.

When you say 'by all accounts' is there any discussion on here as to why bas Intercooler is better?

Go to the search bar at the bottom of the page and type in B.A.S. Intercooler v Allisport Intercooler, and have a read.
Pete Bell was doing fine selling the Allisport so going to all the trouble of designing and producing his own speaks volumes to me. He claims better flow and cooling but I can't verify that without doing a comparison.
There is no risk running the tune without an intercooler upgrade. The only downside is less performance.
I drive mine on the standard IC with the 170 tune and I drive fairly hard. most of the time its fine but with high ambient temperatures the performance drops. I tend to believe Pete's claims because I have found him to be a straight up genuine bloke who seeks to get the maximum performance from his products.
Situated where you are, I'd suggest that you upgrade your Intercooler. Either one will be good for your stated purposes and as I said there is no risk if you don't but you will find you will want to.

The other factor to consider with the tunes is if you plan to fit a snorkel.

Pete did extensive dyno testing and flow testing and all the snorkels drop power.

The safari having the lowest impact

thanks Billy T, very helpful.

...it's a shame Pete can't offer the spare ecu any longer. That would be real peace of mind for regional remote areas. I'll need to source on because I'd prefer to keep my original ecu stock if possible as a back up.

Cheers Tombie that's good to know. So 170 tune would be preferable with snorkel.
