i would like to know what you guys think of garrett truck coolers. cos i have had mixed reports about them. one is they are too laggy and don't flow as much and the other is it doesn't really matter cos you only lose about 2rwkw anyway..

anyone like to clean this up for me and other people interested in getting truck

coolers.

buy a decent cooler, if you fark around trying to save a few bucks, it will only cost you in either performance or dollars when you fit it, realise it is crap and fit another one.

unless you drive a truck, dont waste your time and money. Get a decent jap brand or hybrid, second hand GTR etc, something that is a known good thing, and is desigened to work with your application.

ive got a garret custom cooler made for my skyline and its one of the best cores you can get. Ive had very little psi drop and increase in top end air flow. With any cooler you will get minimal lag due to the piping being long. Ive been in a mates skyline with a brand name cooler and have noticed little difference between mine and his. So in my opinion get the garrett you will be suprised how well it does.

cheers

i think the cores are ok... as long as you have good pipework and good cast end tanks to go with the intercooler core, then it will be ok. but i have seen many vl owners with those truck coolers with end tanks that are 90 degrees at the back of the core.. now those are the ones i would stay away from.

A lot depends on how far you have to cut it down to make it fit. If you get a cooler from a 600 BHP truck that is four feet high, and cut it down so its only one foot high, it then might be ideal for a 150 BHP truck.

There are too many if's. It might be o/k and it might not. I am with Steve on this, get a proper aftermarket cooler, or a GTR cooler is a pretty good start for a lot of things.

Even if Garrett cores are the finest designed cores in the world, they still might not suit a totally different application.

Every 1psi pressure drop across the cooler is 1 psi less boost your actually getting from your turbo. Say if your turbo is making 14psi and you have a crap truck cooler that has 4psi pressure drop, ur only actually getting 10psi.

So get a proper cooler with the least pressure drop as possible, that also cools well, as every 4 degree drop in air inlet temp is 1% extra power.

Not all cores are the same, and often truck cores are let down by shocking end tanks that hurt flow and dont promote even distribution and good cooling.

So not so much a matter of the core being good or bad, but i think the avergae result of using a truck core is poor, but not really entirely the fault of the core.

By the time its chopped down, ned tanks made with new piping, is it really any cheaper??? Doesnt represent the same $$$ savings it once did when coolers were 3k installed

There are that many different types of truck cores available that you cant just write them all off.

Some have quite large runners that will flow no problem, others have massive spaces between relatively small runners that are designed to allow more air to the radiator (generally the ones that are 4 foot square) and will mean it doesn't cool for shit once cutdown.

That said, you can buy a new hybrid for as little as 550 that will do the job nicely and save yourself alot of time/trouble/money getting end tanks fabricated to suit a truck core that may or may not do the job.

I used to have a Garrett ex-truck intercooler on my FJ20.With only 10psi blowing through it,the FJ made 246HP at the wheels.Now a brand name core might have let it make 255HP,but 246 isn't that bad either....My cooler had thick cores,and was 3inches think.If you make decent tanks for them,I don't think they're too bad.

I have heard that truck coolers are fine, although on serious performance 6 Mick from Micks Metal Craft says that they are not suitable. He believes that they are made to suit a trucks rev range. Where with performance cars he said rev out much more so a custom or aftermarket cooler is much more efficient.

hope that helps

:(

Rev range??? surely cfm is cfm, whether its being made at 3,000rpm or 7,000rpm.

I agree.Revs has nothing to do with it,it's the flow.Another thing,when people say "they get a 400HP truck cooler,chopped to a third of its size and they still expect it to flow 400HP." Well,why wouldn't it? Take into account that most truck engines are 10L or more,and require massive amounts of air flow,compared to a 2L or 2.5L engine.

Truck inercoolers are great - if you have a truck.

They are useless on a performance car.

Mario.

My friend has one in his his 392rwkw supra, run's 10.8, another friend has one in his t28 equipped 180 sx, still makes the same 170rwkw on 15psi as everyones elses does with proper coolers. Another friend had one on his vl turbo with 240rwkw, changed to a hybrid core and it made no more power. So I'm not sure what to make of it, I've always bought proper cores. Also if anyone has ever looked at the original Nizpro cores(the massive ones)they are definitly truck cores, Simon must of made a mint of these as he charged around 2 grand when new.

who cares, dont be so tight. U have a performance car, spend a few hundred extra and get somethin that was made for ur car.

So, if large frame turbocharger development came from diesel motors, why do people persist on putting them on performance petrol cars? Hell, I think that the majority of turbocharger design came from truck or heavy industrial motors.

The TA45 is a good example, it's a truck turbo. But TRY-09S seems to be doin' ok from it. Greddy turbos, as SKid has pointedly referred to, are a Mitsubisi Heavy Industry product found on commercial vehicles.

CFM is CFM, and if it can work (and work well) in an application that it wasn't specifically designed for then what's the problem?

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
