gu 4.2 intercooler

http://www.airpowersystems.com.au/safari/turbo/gu_td42t/intercooler.html


Tough Torque:
At just 2,000 RPM, the Safari TD42-T Intercooler System produces a tidal wave of torque. A 16% increase at the wheels over the standard vehicle. If you've ever traversed long stretches of sand, you'll know what that means.


Real Power:
Installed on your TD42-T turbo diesel, Safari's Intercooler System delivers an 18% increase in power output at the wheels over the standard Patrol. That certainly takes the russian roulette out of overtaking.

For around that amount of money you could look at getting an ARB rear diff lock. Now they would make an incredible difference in a long sand stretch over almost any increase in torque - what's the use of having one wheel spin more than the other to get you somewhere.

Would like to hear people's views on that opinion.

any significant power increase will cost money..

Some say IC's are not worth it.. But Turbos cost around the same, and everyones willing to throw them on, for around the same increase. Yes websites claim 50% more power ... but thats at the blinker stem, nowhere near the wheels!

One particular benefit of intercooling is the lowering of thermal stress to an engine. Lowering intake temps then allow you to increase boost pressure to a level where your exhaust gas temps were running previously. I don't know of any turbo diesel truck running on the road which isn't intercooled.

Thans all for your responses.
This has given me something to think about if it is worth it but at this stage i don`t thinkso.
I have to try and find a second hand one now here in vic,but they are scarce,and i will give serious thought to putting my money into diff locks
cheers TIM

Timbo, firstly diff locks are great but are not a panacea to solve all driving environments,Ultimately, the tyres have still to grip the ground. I have been searching for horsepower myself, I too own a GU factory turbo slug that will not get out of it's own way and I have spent some serious money thus far. I have a hill climb near home where I can check the various stages of "power plays". At a given mark, I roll on at full throttle and check the terminal speed at another mark.
Before any work the car went from 80km/h to 90km/h on the hill, 4th gear held.
After the 2.5" exhaust(no other changes) the readings were 80km/h to 96km/h.
Then tuning work, viz timing, injectors ultrasonic cleaned, alterations to boost compensator and fuel srew. Readings went 80km/h to 98km/h. Then I had a full power-up kit installed and the safety blow-off valve removed. Readings are now 80km/h to 100km/h. What is not reflected in these figures is the off-idle and low torque increases, which have improved significantly. Fuelling and power can not be increased any further due to temperature concerns and that is where the intercooler comes into the picture. A measure of reliabilty is inherent with the I/C and and further, minor boost is sometimes a bonus too. The factory turbo is now delivering air at 11.5 lbs and also much sooner than stock. The dyno figures have little meaning unless comparing car to car on the same machine, however torque has doubled over stock reading and is producing 98kw at the wheels at 120km/h.

intercoolers can be sourced for far less than 2k.. boy raqcers have been using jap import intercoolers for ages at a cost of around $150-250.. plus piping and hoses. landrover disco tdi owner overseas have been using jap import intercoolers and injector pump mods, and obtaining exellent results.. would be worth some further investigation.. there is heaps of info on the web...

check outhttp://www.autospeed.com for info on jap intercoolers and turbo boost mods... most of the info you have to pay for there is some free info on the site..
