Thread: Puma turbo upgrade

At the risk of hijacking the thread,
What is the path to increasing bottom end torque as opposed to top end hp. Without opening up the block.

Is the final result determined by the ECU mapping?

Andy,

On a 2.4 that is certainly the case. Alive Tuning gives you two maps as standard when you buy the Atric device upgrade (at least was the case about a year ago) and one is usually a freeway tune which can include removal of the speed limiter and a second one for towing and slow, low power stuff.

I haven't kept up with the 2.2 options, but a good intercooler (Alive, Alisport, BAS etc) and an ECU remap makes a massive difference to these engines.

I've got the Alive Ultimate Defender intercooler fitted with a BAS "balanced" remap and my 2010 90 pulls like a train right through the range.

Cheers,

Lou

I have the Bell VVT and a BAS tune in Defender TD5 and loving it. The hybrid has been removed from Disco and will be replaced with a VVT in some time it runs better with standard turbo the with bigger hybrid

I would really like to give it a go but the cost is crazy, anyone got an old puma turbo laying around they would let go cheap?

Try again with a different subject - his email filter is pretty strong and sometimes don't get through.

Hope the "upgraded" turbo is thicker and stronger on its mounting flange that the stock one.. DEFENDER2.NET - View topic - Turbo leaks again!

Well going through some old posts i stumbled across this, i ended up getting the alive hybrid through Bruce Davis, at this stage i have gone through a few tunes but never been 100% happy with the results, the car is back with Bruce at the moment and he is going to have another go at the tune to see if we can get better results...

Basically the tune was ok up top, good increase in power at higher revs but sacrificed to much down low for my liking - with the old turbo/tune i was making good power from 1650rpm, while its better then it was with the stock tune its lost that punch down low but really comes on hard about 2100rpm now, i also havnt been happy with the increase in black smoke since either but each tune i have tried has made a little difference and got closer to the mark. I haven't chased it for a while until now as it had to go back for issues with the PWR radiator i also got off him so getting him to try and sort the tune once and for all...

I cant help but feel this tune/turbo setup is more suited to a little 90 than it is to my fat arse 130, its been a little over 12 months since it was done and i feel while its making much better power mid to high revs value for money with this mod isn't great. but lets see how it comes back this time, i might be surprised.

Look forward to hearing your thoughts on it.

Has anyone here had a turbo gasket / over heating issue with a BAS remap? Like some of the guys on Defender2 forum have?
