Hello, Robbomaz!
As your Jackaroo?! The amount of the boost you reached? What Ecu use ?! what ratio use in charge to 2-3 psi ( standard motor 6ve1, without the catalyst). what improvements have applied for 4l3e? Thank you! :-)))

Yes, Jackaroos! Most setups are just using 3 psi with the Isuzu ECU, with around 175 rear wheel hp.
One is using 7 psi, standard ECU with a 7th injector for 245 rwhp
One has aftermarket injectors, and a Haltech ECU for 265 rwhp on 8 psi - now has the engine apart to close the deck, lower compression pistons and tweak the oil galleries in anticipation of 'going nuts'!
All the hp numbers were with 33" tyres. Cant help regarding the auto sorry, we are all manuals. The US guys would be the auto experts for sure!
The answer is more power! What was the question?

Thanks for the reply! At a pressure of 3 psi, what the ratio of the diameters pulley??
Petos, Hello! I am on our Russian forum and machine bought from the forum, read all the back and forth, generalizing information :-) will Soon begin its branch on the construction of the compressor VX

Those are some low numbers (for base boost and power). I have been hearing 5psi with a basic Alpine kit. As HP figures, which dyno are you using? DynoDynamics?
Have you guys considered using AEM FIC for tuning? It is a piggyback system with a much better approach than the old Apexi AFCs.
96 Eclipse Spyder GSX (already turbo, AWD swap)
93 Eagle Summit AWD (4G63 turbo swaps)

We are always conservative in power claims Leon
While the numbers seem low the gain in power is close to 30%, which is not to be sneezed at.....Seriously though there is a method in the madness
You have to consider what environment we developed for - it was quite a simple idea - the main target (don't laugh now) was to be able to achieve 'float speed' over the infamous corrugations on the Canning Stock Route, about 105 km/h is enough speed to skim the tops - in the bottoms is a fine clingy dust that is worse than mud for rolling resistance, you either do 100+ or 20, anything in between shakes everything to pieces
With a truck loaded for two weeks camping even redlining third before picking fourth she simply didn't have the grunt to hold float speed even at WOT, with fuel use around 35 litres per 100
Even with 280 litres of fuel tankage that's not enough. Fuel depots can be 1000-1200 km apart out there.
It is possible to get a very very long way from the nearest human/fuel/beer etc in Australia (Well, maybe not the beer) so the first priority was bulletproof reliability
Here we found that 5psi was 95% or more injector duty cycle, with the start of detonation audible in the headphones so we took 80% duty cycle and no knock at all on 91 octane as the base. In parts of the Outback the only fuel is a product called Opal (developed as a fuel you cant get high from sniffing...a problem in some of the Indigenous communities...you can fill in the blanks there!) which is in the 80's octane wise, so we considered that sometimes you might have Opal mixed with your 91-to-98 octane good fuel, or a whole tank of the stuff.
All the kits we fitted we did 'before and after' on our own Dyno Dynamics.
My own truck dynoed at 134hp before, 175 after on 3.3psi at 81% duty cycle
The truck that did the Stock Route did 128hp before, 174 after, 3.2 psi and 80% duty.
On a revisit to the CSR last year he found that not only could it achieve the required speed in fourth it did it at 40-50% throttle, and returned 22l per 100. This despite having added a rooftop tent and roof rack.
Mission accomplished

Hi guys...
Been following this thread for years...
We ran 0.48 bar (7psi) on 95 with stock injectors with no problems on the old alpine chargers... (201 rwhp) I have the graph somewhere... (122rwhp before charger)
My friend runs a vortech charger at 8.7 psi with stock injectors and piggyback with HUGE inter cooler... producing 240 RWHP!!!! Its been running for that for about 140 000km with NO issues whatsoever... It runs stock compression as well....
The inter cooler makes a HUGE difference to get the temps down...
I prefer the roots charger as the centrifugal ones has a turbo like lag...
This is my build....
Hope to crank it in the next 2 months...

Always fascinates me how what you would think are the same cars/engines give such different results!
Interesting thread too - apart from when you drop into your mother tongueI grew up in die Vrystaat - or Oranje Vrystaat as it was then - but since moving to Au have lost most of my Afrikaans
I've talked to Dave about the intercooler manifolds but actually bought any yet. I'll be interested to see your results!

We were in SA from 68 to 77, lived in Maseru in Lesotho & went to school in Ladybrand in OFS, then later moved to Ladybrand. Before that we were in Pretoria. 63-68 in Lusaka, Zambia and then Salisbury, Rhodesia (Harare Zimbabwe as it is now)
We moved to Au in the mid 70's....my fathers contracts with the SA Police and Lesotho Mounted Police were ending, plus looked like all hell was about to break loose in SA,Not quite 'Casspir school bus' stage when we left but heading that way..

We have done one for a guy who tows a big caravan, used stock ECU & injectors, added a 7th injector and controller, boost 7.5psi and 245hp on our dyno on 33" rubber. Intake temps were up, an intercooler would make a big difference and probably some more hp as well. It goes hard with no load!
