Outer Limits 4x4 Board

Yeah it's unbelievable the difference in flow for eg: cummins 6bt ve rotary in a case dozer These are tested with by memory 027 orifice plate injectors and if you use 12sd12 test injectors There will be a massive difference in fueling I think it was 20-30 cc's difference and the cummins Runs a multi...

It all depends on the injector used from oem , the Nissan td42 single hole nozzle will flow totally different
Then that of a Toyota 1hdft etc ,also nozzle opening pressures Are totally different aswell

What I am getting at is when people quote there pump was set to 120cc's of fuel delivery it would most probaly be set on 12sd12 150 bar test injectors and not actual fuel flow at the nozzle which is used in the vehicle For example 1hdft uses 87cc's of fueling at 1800 pump rpm to produce 125 cranksha...

There is some serious issues if you need 60PSi to burn 120CC of fuel. 120CC of fuel in a well intercooled/turboed TD42 will yield 150RwKw all day on 35" tyres at 23-27 Psi with good safe AFR's. Which equates to around 200RwHp, its a very common upgrade fuel figure which always yields the 150Rw...

On further thought that would not work so well. You need better material for the crank if you stroke it,the stresses on it are tremendous once you start spinning it with big heavy pistons, throw lots of boost and fuel at it then take it all out at one end with big sticky tyres. Aren't the Brian Cro...

Here is the style that we run
Tapered to increase air speed to the back cylinders

"Northside 4x4 ,We have never been targeting marketable and profitable items, just concentrating on making sure what we do sell is the best you can buy. Well you must be going to sell our fuel pumps and matt's turbochargers then .... LoL... Lets get back on track about intake manifolds, and no...

Our temps were done with Motec sdl3 , e888 expander and exposed tip thermo couples ( quick to respond )
I can run 9 thermocouples all up plus all the other sensors . It is handy as I can log about 7 hrs of data , (16mb of logging)

Remove the fuel cut solenoid , take the plunger and spring out of the solenoid then reinstall if the engine will then run it is a solenoid problem , obviously you wont be able to shut it off with the key but this is a good check as it elimnates electrical and mechanical if it dosn't run well then yo...

As for the 30 temp spread , not worried at all as this is a really good figure and actually could be caused by restriction in exhaust manifold , eg pressure drop causes energy loss (temp increase) it is very interesting to see what temp you have at each cyl and then at pre turbo on the std exhaust m...

Fuel spread can also cause temps to vary between cylinders , whether its pump or injectors flowing different amounts .

My TD42 wagon runs with about 30 degrees spread across all cyl's

It's a 12mm Plunger

And like andy said it wont rev enough to do what you want

You should come up for a look David!! then you could Compete in the WTC
on the weekend!

So asuming your targeting about 170 RWHP max or so with that turbocharger combination its quite achievable with a 11mm hyd head , as for undertaking the work yourself good luck! , i have spent ( as well as alot of other fuel tec's)countless hours trying diferent combinations etc on a fuel test bench...

Make sure who ever scanning the car has a bosch KTS scan tool as some other brands can give you all weired and wacky faults , and as Andy has meantioned clear codes and go from there .dont stress about pump comm error by all means dont replace pump untill needed ie fault regarding wiz sensor ( fuel ...

As RD Meantioned the dual mass flywheel can give these symptons rough idle and as soon as you give it a blip on the throttle it stops shaking returns to idle and then starts shaking like a mo-foe, you can also hear the clutch/flywheel rattle upon start up which is a good sign. Is there engine light ...

I stole this from mud rihno's site image thanks to sierriajim

Here is one for Kent Battle , 452klm's of sheer glory!!! http://i1223.photobucket.com/albums/dd514/Swafftec/finke030.jpg Can this man come through with the goods ???? http://i1223.photobucket.com/albums/dd514/Swafftec/finke231.jpg Billy thinking , man i could do that ..... In a truck!! http://i1223....

I cant wait for the drive , i just got to finish my car! Also im calling Stevo out , I dont recon you have the 2 kilo rump in ya. There it is , i said it . ill pay for it if you can finish it (in one sitting, On the night) Man it's gonna be good , and also im putting it out there Rentsch no 1 in the...

Definitely have nothing to prove though, just doing it to see if it can be done. Power out at 5500,6000rpm isnt unheard of for a diesel. But not an OEM diesel . VW golf revs to every bit of that with their 1.9l eui system, It is going to be very hard to get a td42 to rev to that and make power due ...

You could make a 2 stage boost control for the compensator with a simple
air toggle and needle valve . Also how would you use pyro to limit fuel or
does the e-boost have a amplifier for the k type probe?

http://i1223.photobucket.com/albums/dd514/Swafftec/Heathlawson.jpg I found this on are's website , im not sure if it was the final combination of Heath's vehicle . As you can see the 4.2 has come a long way in the fact of max hp and the RPM . Remember we are reving ours to 5100rpm and are still mak...

This has probably been posted a million times but i am after the most current info . Who has had a pump/ turbo combination successfully built for them to achieve 350+ RWHP in a patrol 4.2 TD. ( for this post i am not talking about all the internal work and extra add ons just 2 things, the pump and ...

So the short version of that is. If you use your car everyday for real life purposes such as towing, beach trips, driving to the shops, taking the kids to school. A good fast spooling turbo and standard pump setup that can still achieve 150+kw atw would be preferable having the pump modified to pro...

Thanks for the reply, I'm glad you cleared that up as you had me scratching my head as I have dialed these camshafts and was wondering how scavenge affect on valve o/l could work with this particular camshaft . And I agree more, emp means the more the piston becomes a pump and has to push out what i...

They run a bosch injector, they also use 90 to 120 v to lift then drop back to a lower votlage 12v or so , and when they switch off they store the energy from the solenoid to use again . so the 5 injection cycles you oviously cant see by eye (looks like one injection). Motec sound promising in bring...

[quote="Dieslex1 EMP is actually lower than IMP. This lower ratio improves scavenging dramatically and improves the resulting AFR (due to better VE) for a given boost. [/quote] Can you tell us what you mean by scavenge ,are you refering to valve overlap scavenge ? We are running a ratio of 1:1 ...

In reply to intercooler , even though off topic a bit

A good FMIC with good tanks for flow, dumb , simple and works well!

Good cyl head porting will cost close to $300 / cyl
On a cast iron head . You will pay $200/cyl for a alloy head
And man your fuel pump is cheap ! I might have to get you
To do my pumps at that cost!

Duramax would be a great option but i believe the boys are looking at doing CAMS events aswell and this will be out side cams regulations 4.5 Turbo diesel and 3.5 turbo petrol is all you are aloud for cams or 7.3 NA diesel (yawn) and 6l Na Petrol I dont believe They are as highly strung if done prop...
