I have a gq 4.2 petrol goes well on its own but with camper trailor it lags on hills I was toying with the idea of turbo, nothing huge but just enough to bring it back to life, when required. Has anyone done something like this or am I wasting my time:headwall:. I know a diesel would be the go but I have this for now. Steve

A non turbo diesel is going to be just as painful and slow. If your tb42 is fuel injected it would definitely be worth doing, if it's carby you have to weigh up if an efi conversion is worth doing along with a turbo conversion a lot of money and work if its not efi.

G'day , the notion that a diesel will not loose speed on hills etc I wish were true. a couple of weekends ago I was towing a trailer , had a huge head wind and had four adults in the car on a big hill doing 60 km/hr.:headwall:
Turbo diesel td 42, but to its defence the boost was only set to 4 psi, and needs to be dynoed etc intercooled

So either way, petrol and diesel, your tryng to push probably 4 ton up a steep hill, so on the flat with no head wind , your vehicle needs to doing it at probably 50% capacity so there is plenty in reserve when theload doubled etc. I didn't do any calculations, any engineer could determine work involved to lift 4 tonne 1000 feet etc. At 100kmhr most of the engines power is going into overcoming wind resistance ,

Mind you a week later, with 8psi of boost , no trailer, a slight tailbreeze and cool damp wet weather and only me in the car I was still doing 110 km/hr at the top of most of them.

I have another gq with a tb42 , and if money wasn't an issue , I be researching a Sprintex supercharger or similar.

People have done it, FYI one bloke on here has one turbo and one blown, he has said many times, go to with the turbo over the blower.
YMMV

why go efi? is that throttle body - single point ! do they still use su in some applications

Yeah but in one of my favourite Chuck Norris movies he buried in his fourby and he starts the engine and hits the supercharger button and hes gone!

I'm sure mythbusters would some reason why it couldn't happen.

No mate, it was Chuck Norris so it really happened. Maybe if you get Chuck Norris to have a look at your Patrol he might be able to steer you in the right direction.

there is a notion that diesels don't lose speed up hill? i second the wishing it were true. i reckon an old lady in a wheel chair could beat me up most hills, but she cant idle up a slippery dirt track like i can!

That's gold, couldn't stop laughing at this reply.

More boost. I increase speed up hills when I put my foot down more....

Bugger what old chuck can do ,
What about ol Mad Max and the blown Falcon !!!

Superchargers of a switch,oh the magic of tellie

They work in different ways,blowers are crank driven, turbos not
Many advantages/disadvantages of either

What power out put are we talkin and for what outlay would be the crust of the question
How often do ya tow loaded,how much power extra do ya need,how much do ya have to spend

If ya think the TB42 lags loaded up hills feel sorry for our smaller engined brothers
