Aftermarket turbo

[Ben-e-boy]

I don't know mate what ever Nissan sell em with I just loved my ute as its indestructible but lacked power so I found a guy that knew his shit and told him I wanted it to go hard and fast nearly $9000 later she flys im not here to pull ya pud
I just answered a question I to was asking 6 months ago and no one on here could help mine flies and I just stated what was done I don't know what the new ranger has but for example today I smoked one towing my 1.2 tonne duel axle trailer with my mixer barrows and tools on to the dude that asked the question its possible just have to find someone that does know there shit and not a IMO msg me if you want me to let you know where to go as there is plenty of jokers that claim to know every thing

considering I paid 42 grand for it 9 years ago with a 100 % tax rite off and never spending another cent besides this and have been offered close to what I paid you can make all the jokes at me you want my friend but how many of you own a 4.2 with just a tad over 100 k on the clock ? so If owning a smick 4.2 that would smoke any of you guys makes me a joke I can deal with that

Firstly not once had I proclaimed I know everything... secondly I called you out for outragous power claims which you still cant prove.

For the simple fact that you have dribbled out some figures and admit to getting confused between hp and Kw, does indeed make you the joke.

I however am very thick skinned and find this very funny.
Good on you for having a GU ute that you can sell for what you paid, I only own a GQ that looks like a crappy farm ute but looks dont mean shit when it comes to power figures.

I have already modifed my 4.2 and quite frankly gone way beyond your "disco potato", 11mm pump and a factory intercooler.

Again through up some footage or dyno.

cant read either don't have 11 mm pump or factory intercooler at that stage id parted with about $1500 what a bunch of red neck dicks please remove me from your shitty group as I have a life away from here

B rad,

I too have posted wrong information before and it was brought to my attention,and you either suck it up that you were wrong, or you pack up your bat and ball and go.

I was a little upset, mainly at myself, at being called, but sucked it up and continued on.

No-one wants you to leave or not contribute, but the internet can be a wild and wonderful thing, and you are posting, with no knowledge of who you are, where you are ... you could be five years old, living in Mongolia, sprouting crap, which then becomes truth, and everyone could then run around asking why they cant get 300kW out of their 4.2 D....

You cant blame some of the forum experts for trying to verify your claims.

Maybe, join us on a forum meet up, get to know some of the guys, and there will definitely be some more acceptance of your posts. I think there will be lots of guys that will be genuinely interested in what you have done with your truck.

I haven't met a bad bloke here yet....

There is still a maths behind all of this too. To achieve 300rwkw from a td42 you will need 28 psi on a 3076 with a turbine housing in the 1.85 ar and at 8425 rpm. Our engine only revs to 4000rpm maybe 5000 if you want to push it. So it's still not possible even with that size turbo. Then you have to supply fuel to achieve those figures and be able to control it at the same time and after all that is said and done hope the engine stays together.

There are plenty of jokers out there as you have stated but you are prepared to type shit expect to recieve it back.

It takes a big man to admit on a forum he is a bit wrong But B Rad you seem to have a nice rig, I have a GQ and had it since 1990 and it has had 180rwkw since 1990 and has 190 klms on the clock. But my friend it doesn't matter how much fuel you try and shove into a 28-- of any size turbo housing it will not have the air volume or pressure ratio to exceed 200rwkw not unless you can rev the engine past 8000rpm. If you do the maths and use the comp charts the GTX28/3076 you just cannot make the air volume at 23 psi to do 300rwkw on a 4.2 litre TD at 4800rpm it can easily do it at 8425rpm. So with nothing else considered and 100%VE you can get 300rwkw at 176cc/1000shots at 42 psi at 3800rpm..for a 4.2 litre diesel But it has to be a GTX3076, and all input and output air temps as 25deg C.

Ben, Matt and OldMav when you dyno your trucks is it done in 4th gear?? Have you guys heard of "Bunny figures" ?? Its when tuners do a power run in a lower gear to get big power figures coz on the gear ratio. Do you guys know the ratios for 2nd and 3rd??

[nissannewby]

Yes 4th gear only. Last time I dynoed mine was on a water type dyno and the power is held at a constant instead of a ramp style. These type can be very accurate.

Yes have heard of some tuners doing as you describe, also probe placement for the dyno can alter readouts.

[OldMav]

I do all power or Kw as a calculation of torque of ft lbs or Nm to a ratio to get Kw's my dyno is old and doesn't have a computer attached to do the fancy shoot out crap. As a general rule my dyno calc Kw a little lower than the usual. Its best to do it in 4th as this is 1:1 so you only have a diff ratio to calc into the equation. Also you can add a fudge factor to get engine correction KW's. You can do all this in 3rd gear but the maths has to have a fudge factor added due to tyre resistance size heat build-up, how long you run it on the dyno and so many other factors. Sure I can put 30 inch road tyres on my rig and put it in 3rd gear and just do a no rev dyno pull down and yes it will see a calculated 300rwkw easy, I have done it a few times to see acceleration times against load, so I can adjust the compensator better. But it is not unusual for the ambitious tuner to do a 3rd gear run on modern dynos to give over the top results. Have seem this sort of thing often 5 to 10 years ago.

P.S my dyno is a water load system and it works like this, you flatten the throttle and apply load until you see the highest torque reading or you can apply even more load to stall the engine lol done that by mistake a few times.. So it is not just accurate it is fu#ken accurate because it has one gauge that reads Nm or in my case it reads Lbf.ft

[Alitis007]

Well 4th is 1:1 yeah!? I think 3rd gear is 1.6:1 so if a motor made 140rwkw in 4th, in 3rd it'll make around 220 something rwkw, so a 300hp oil burning monster lol but only in 3rd gear

[B rad]

you guys all clearly know more than me which is why im here and im willing to suck it up but the guy that is working on mine has a 4.2 which does desert enduro racing and says his comfortably can sit at 6000 revs all day long thus being why I chose him and I guess my truck goes well I will get the accurate figures and im sure will surprise
