Outer Limits 4x4 Board

A mate was wondering if you can successfully supercharge the patrol diesel in aim to get get rid of lag. Or is twin turbo easier? Thoughts and explanations will be appreciated...

i dont know why you would bother really, one nice well suited single turbo will do the job very well if not better then a twin turbo setup and costs a shitload less to work out, as for supercharging, you turbo a diesel to get gasses out, you dont wanna ram shit in to create more gasses ...

doesnt a turbo also "ram shit in" although a supercharger is ramming at a slightly lower but contant pressure the turbo is forced induction aswell

Well my understanding is, you can get just as much with super charging as you can with Turbo with the right pulley setup, and because its running off the engine it generates boost while at idle and no lag on take off, also you can have yourself extractors and a 3" system to let the gasses out quick.

Would be nice to do, but for my tastes i will go turbo, easier to do

turbo or super charged are good but turbo is cheaper to set up n easier to install. superchargers have shit everywhere. I almost bought a td42 with a eaton 90 on it but the turbo went better. Dont forget a turbo acts as a muffler and a supercharger does not, so it will be loud with a 3" exhaust.

Turboing is almost free power, driven from waste gases. Great on diesels that arent powerhouses.

Super charger takes power from the engine to drive it, not free. Great for big capacity petrol engines with power to burn.

My opinion.

wot lag???
if it done properly you wont get any,well hardly any,remember the 42 has oddles of low down grunt anyway,this compensates any lag you may get..(unlike a petrol lump)

choosing the correct turbo is the key to sucsess.(ie not too big)..dont forget to intercol and fit egt gauge

Pretty common myth that, remember the turbo is a restriction in the exhaust robbing power and generating heat, it all comes at a cost

my point is, nowhere near what it takes to turn a blower

the biggest problem with super charging seams to be finding room to fit the supercharger and belts etc.

with deisels turbo's are certainly more effiencent but lag and lack of down low and low throttle boost are a problem.

no reaon you can't run both. a supercharger will give you that off the line grunt and help get the turbo spinning up quicker. once the turbo is running a full speed the supercharger can be bypassed. i uderstand that that working out the point where the bypass kicks in is a bit tricky.

still the catch is always $$$ and room to fit it all in.

I agree with you dazza. I also like the idea of supercharge for bottom end and to get the turbo spinning for top. Its time for more research. I currently have a td 42 running garret 25bb with good power and torque but it suffers down low with the 35s on. Appreciating everyones thoughts and opinions...

trust me it aint worth tryin to do a supercharger and turbo, ive seen it and its benifits are far less in comparison to the ferkuking around that goes into it and if the problem is that u want power from 0 to the almight 5000 revs a TD42 is capable of, get a better engine, if u simply wanna make more power out of that motor, keep it simple and just do a turbo, easier to do and better performance

Change Diff gears - cheaper than SC set up, eases strain on drive line and brings your speedo back to normal also.

My mate has one, was hoonz's old beast, it is like a tractor through the typical diesel rev range, nothing slows it up, turbo's that I have driven are nothing like this for tract-a-bility But it doesn't have near the wound up punch of an aftermarket turbo.

I think what people miss is that it doesn't matter how much power is robbed in the process of making more power it is the end result not the equation that matters.

Me I would go turbo, and put up with the relative increase in lag compared to this supercharged setup. Actually I wouldn't go either happy today to stick to my NA TD4.2

Yes it can be done, I have done it. Worked unreal, no turbo lag and still made 140 hp on the ground. I still have full kit, manifold, supercharger, belt, all pulleys and mounting brackets. Recently removed for V8 conversion. Contact me at prawnspatrol@hotmail.com if you have any questions.
