Rob from MTQ in rocky, really knows his shit and has a doozey of a pump, 2 stage big hp model. Not cheap though, I think it was atleast 2700+ and that was nearly 2 years ago

Phone Shaun at Swafftec Industries had my pump supersized and injectors done to suit big turbo and holy crap its quick. What he doesn't know about pumps insn't worth knowing, prob find a bit more competative price too

with the injectors done and pump tickled what is your economy like now, did it make much difference?

well i asked for massive hp and torque and thats what i got, the compromise was always gunna be ecconomy. haven't done and figures yet but at a guess it prob ain't real good. but saying that i've been up it like i stole it.
the pump is outputting just over 3 times the max of a standard pump and i'm punchin 30psi max outta a big turbo. ecconomy was never my thing

haha far out it must be an animal
would be interesting to see the figures on dyno, I have a gu 4.8 petrol, it has great power but the economy is very sad, this is why I am thinking of going back to a 4.2 td with some modification, but i think at the end of the day it will be 6 of one and half a dozen of another. a standard 4.8 or a modified 4.2td with a large pump will most likely be similar on fuel.

some of the highly modified pumps are getting better economy than standard pumps. 30 Psi needs ALOT of fuel to keep going, if you ran 20 Psi you would prolly still get fairly good economy.

they can be tuned for economy i average round 13lt to the 100klm with a swafftec pump running 30psi my max fuel comes in at 20psi best thing would be to ring him and talk to him he's very good bloke.
