Well a few weeks ago I asked about increasing the power and maybe torque and getting some fuel consumption benefit of my naturally aspirated 3.0 diesel dual cab hilux.
I didn't want to go the expensive route of a turbo looking at up to $4k from enquiries round
brisbane.
Headers and extractors are about $1k but no confirmed reports of a significant increase.
So I went shopping for a chip cause I had the EFI motor and got close to buying a DP or a Tunit but found someone next suburb who was fitting the morepower chip and said they'd get the same result but lower down.
It was a you drive, then he installs, and then you drive again, and if you like it you pay for it and if you don't you only wear the installation fee.
I took if for the drive after, into second and my head hit the headrest - was a I dreaming ? Now this is no rocket ship and never will be but I was not expecting the new pull of the second gear.
So paid for it, fingers crossed I was not my own victim of expectation.
Northside Carburettors in Geebung did the dyno
test, didn't know him, yellow pages job, but cool super friendly
young guy in a large shed with a zillion carbies on one wall and a dyno tuner. Would recommend him to anyone. Cost $90, too cheap I wished I had paid him more. If you got a carby problem go there.
What I noticed during the
test - without the chip some black smoke near redline. With the chip it billowed black smoke a lot more near redline, can only think over fuelling, but I almost never go near redline so I don't care. Maybe off to some "cost effective maintenance" stuff, they are a only few suburbs away.
The combined dyno chart is below, I compare this to the one on the DP site for the 5LE, and which is more expensive. The DP seems to give the max Kw increase at 90km/hr, and a constant what looks like almost not noticeable torque increase.
The morepower chip seems to give me the equivalent of the DP peak but at around 1800rpm, but bugger all up at highway speeds (my eyes could be deceiving me in the comparison).
The torque curve seems the same but gives me about a 10.7% (to my eye) torque improvement and at the 1800rpm range. Was hard for me to compare this to the DP dyno
test so any help there welcome.
Am I happy? Sort of, there is a difference to the driving. And I do most of my off road stuff rambling along trails and beaches and sand roads in about the 1800 - 2000rpm, so fantastic result for those types of driving. If I were towing or mainly on highways, maybe the DP is the way to go.
Next will be headers and there I'll stop and be happy with what I got.
Any comment welcome and if anyone can interpret the figures for me into percentages that would be really good. I am no expert at dyno charts. Too early for any fuel consumption
test. The DP talks about a 12.5% improvement, but I reckon it's only at that highway speed.
I am enjoying the change to that 1500 to 2500rpm driving range which is where I most seem to be (except on the highway). And now any stretch of road I am on and where I can't see a traffic light I drop into 5th straight away and it holds really really
well at 60-70km/hr, hills and all.
And one last thing, the guy selling these in brissie is an ex radio technician and sells lots of hiclones. I gave him my opinion of the hiclones, not high and I have had one, and
well, each to his own. It turns out hiclone are the company importing these units from the UK. I'm happy about that, so long as Hiclone was not making them ... Cost - $1,100.00.
