Picked up my truck yesterday afternoon, after Sean Calcino from Southeast Qld 4x4. Sean said I got a 25 - 30% power increase
I took note driving back up the highway on the way home to Beenleigh and this is what the gauges were telling me.
90 km/hr,
2000-2100 rpm,
4-5 pound boost.
If I sat on 100 km/hr + the truck was sitting on full boost (7.5 pound), so i think to save fuel I might just learn to sit on 90 km/hr.
I am over the moon with the increase in power...a few hills that I would of been struggling in fourth gear, I could hold fifth. and on the highway coming home, when I used to get to the stretches with the long enclines (I used to drop back to fourth) just a little bit more pressure on the go pedal and she would pick up straight away. No going back to fourth now!!!
Very impressed with the outcome....money well spent!
cooler, more dense air thanks to an intercooler will allow more power to be tuned for.. and higher boost levels to be run..
not sure what car you have or what turbo you running, but on coasting at 100km/hr you should not be on boost but rather vacum.. only when you stomp on the pedal should boost build..

Since when was i/c a waste of money?
You better tell all the silly car companys to stop wasteing their money i/c their turbo vehicles.
A boost compensator will give him far more performance than an intercooler.
A fuel compensator is just that....Adds fuel as the boost rises so the engine does'nt lean out.
A i/c is not only for more power but also for effieicncy.
Cooler air is dense air witch in short.......bang for your buck.
The bonus of a i/c is more power.

Whether an intercooler is worth while or not all depends on how much boost you are running (or want to run). I would also think that when you are coasting along your turbo should not be making any boost (unless its supercharged?) thus still maintaining your economy. When the engine is loaded up boost will come on.
The car in question is a uted HJ60 landcruiser with a 2h 4.0L diesel.
At 100km/h, this car will be on boost because you arent coasting (its a brick with wheels), although, "coasting" you should only be running about 4-5 psi, 8psi when you start to accelerate.
I used to have a turbo 2h, with a front mount intercooler and it was a beast. Intercooling allowed me to run more boost, and up the fuel.
Intercooling is definately worth it on this truck because the 2h does not have piston skirt cooling, so any effort to reduce engine temps will give you better engine life.
A boost compensator does nothing for performance on these engines. Compensators are used for emissions and fuel economy. When you boost up a 2h, you set the fuel levels to be correct at full boost, i.e best performance. The downside to this is the increased emissions when you arent on boost.

What he said.....thanks Carts!
So what sort of $$ would an intercooler set me back...might be something I look at in the future....the NEAR future!

wouldn't turning up the fuel after intercooling negate any decrease in thermal stress?

????
while i have no idea on those motors, the whole point of boost compensators is so you can actually run max fuel without blowing smoke (excess fuel) when off boost.
edit: soz, better way to look at it. a boost comp simply stops the motor overfueling when it dosn't have the air (boost) in it to burn the fuel.
its kinda pointless shoving the fuel in when there is no air in there to burn with it, you don't get much more power (economy suffers), can cause problems (eg cracked heads), not to mention annoy people with black smoke and dpending on country etc be illegal if its to bad.

i don't think its such a good thing to up the fuel to match the intercooler (exspecially air-air) with a mechanical injection system, simply because the cooling varies and there is no way (or very hard) to adjust the fuel to match the air temp.

I would agree. Although i think typically one would install an intercooler for the benefits of power gain (by turning up the fuel)
Certainly installing an intercooler whilst remaining fuel settings to that of a non intercooled setup would decrease thermal stress. I just thought it was an interesting comment from carts, as i believe he installed an intercooler with the intention of upping the boost & fueling.

Yeah this is correct. You are right in what you are saying. Upping the fuel and boost does somewhat negate the benefits you get from intercooling as far as thermal stress goes. However, when mine was originally setup, it was tuned with a pyro to only reach a certain exhaust gas temp, which was considered safe for the 2h. After it was intercooled, those temps dropped right off, which allowed me to retune it back to the optimum setting for this motor, without overheating. The benefits were more power, without adding to the thermal stress of the motor.
Some people go ballistic with boost on these old things, and are cranky when the engine fails because of cooked pistons and cracked heads.
As far as emissions go without boost compensation, its manageable by modifying your driving technique (don't put your foot flat to the boards, unless you are on boost). Flat out, it was tuned to blow very minimal smoke.

Interested because I want to do mine(89 HJ60) in the near future. Ive got a freshly rebuilt 2H and shes just waiting to have air forced down her throat.
