How much boost
How much boost
Just wanting to know how much boost can you get out of a TD4.2 non intercooled without playing with the injector pump. Its a 99 GU wagon and another thing is what is it standard (boost) from factory.
Re: How much boost
boost? 80psi with the right turbos

Re: How much boost
Boost is useless without fuel. Running 20psi from a stock setup won't do your EGT's any favours, as the intake temps will be hella-hot. Saying that, with a decent tune i think the GU TD42T's can get over 100rwkw - i'm sure someone that owns one will post up their results.woodiesGU wrote:Just wanting to know how much boost can you get out of a TD4.2 non intercooled without playing with the injector pump.

Stock boost would be between 5psi and 8psi.
Re: How much boost
So running between 10 to 15 psi shouldnt make things to hot or cause damage to the motor.
Re: How much boost
if u were going to run 15psi mate i would deff fit an intercooler even a front mount or top mount, but your going to have to play with the pump timing and fuel to get some decent power out of it, have u upgraded dump pipe and zorst?
mq patrol, zorst, spotties, lft ect
Re: How much boost
even 10000psi wont make your egts any hotter....
More boost = Lower EGTs
More Fuel = Higher EGTs
rich vs lean determines your Egt reading....

Re: How much boost
exactly
and if you want the standard slow ass td42 to get up go for a change,spend some dollars and get more fuel into it and more boost then get it properly tuned.. mine is making 190rwkw with 35's.. i havnt got the time to be fu cken around with standard shit.. its all to slow.

Re: How much boost
So there's no difference in EGT's on a vehicle running charge air temp of say 30C compared to the same vehicle with a charge temp of 130C?
Re: How much boost
its stuff all on the gauge,, leaner the better.. standard tuneup any place will do for td42 turbo is turn fuel 1/8 to 1/4 of turn on fuel and bump up air to 12 - 15psi.. and even that is barely noticeable..
before i did my motor up i had 3inch zorst, dump pipe, standard turbo and standard fuel pump and i turned fuel 1/3 of turn and ran 20psi boost.. ran very lean.. still to slow though.

Re: How much boost
This is a bit off topic, but have you put any air temp sensors into your new setup? Some of the data from the Laminova threads is pretty interesting re: charge temps.THE-Burger-Ring wrote:its stuff all on the gauge,, leaner the better.. standard tuneup any place will do for td42 turbo is turn fuel 1/8 to 1/4 of turn on fuel and bump up air to 12 - 15psi.. and even that is barely noticeable..

Re: How much boost
no i havnt but i have been meaning to for a long time but i dontknow what type of air sensor to put in or where i can get hold of them.. local stores around home dont sell anything like it nor heard of it.. thats VDO and SPECO brands. i recon it will be very interesting. i want to set up a few sonsors.
Re: How much boost
Ben's truck (one of the Laminova guinea pigs) has one or two from memory - maybe give Andy a call (dieseltec) and see what they've used.
Re: How much boost
Ok guys thanks for the info I'll get the 3" pipe and intercooler done than take it from there.
Does any one know of a good Diesel tuner in Sydney?

Re: How much boost
Your saying that difference between a bog stock TD42 and one with a 3" exhaust, more fuel and boost is braely noticable? Don't think so mate, it's like night and day - it may not be like 150rwkw + but there definitely is a big improvement.THE-Burger-Ring wrote:its stuff all on the gauge,, leaner the better.. standard tuneup any place will do for td42 turbo is turn fuel 1/8 to 1/4 of turn on fuel and bump up air to 12 - 15psi.. and even that is barely noticeable..

Re: How much boost
yeah look maybe i am a bit of a rev head, but maximum tune from standard setup or even with the3inch zorst dump front mount intercooler, 15psi and fuel turned up is certainly good enough for some people.. i myself cant bebotherd waiting half an hour to get to 100km/hour then backwards in gears on most hills.. the setup i have now suits me how i want it.. yes i have spent the dollars but i am happy with it and there is no hill i cant do in 5th gear. and in the bush doesnt matter what gear i choose the bastard will pull and pull.
Re: How much boost
anyway his question has been answered. getting offtopic again !! lol
Re: How much boost
Are you going to get pre and post mod dyno readouts? If so, make sure you post up the results for other peoples future reference.woodiesGU wrote:Ok guys thanks for the info I'll get the 3" pipe and intercooler done than take it from there.

Are you going to look at fitting a pyro? If so, it might also pay to get a bung welded in your dump while doing the exhaust upgrade.
