Outer Limits 4x4 Board

Hey there experienced ones.

Ok my dilemna is as follows. building myself up an Fj40 comp truck.
with a fuel injected 304 V8 holden engine.

the 2 options i have so far for radiators are:

a 75/80 series diesel radiator. got this tip from daz who ran a 383 in a fj40. this option would be solid i imagine with au falcon twin thermos behind it. might get abit pricey though.

other option was a VR/VT V8 radiator with factory thermo fans on it.
cheaper option and they obviously cool the 5litre ok in a bommodore.

is there a better option i dunno about???

it will be front mounted.
cost is a problem. so cheap is good.

be used in all terrain kind of events.

Cheers

work out if you could afford to replace a cooked engine, and when you do, saving a bit more to do it right is probably the idea.

a big one!

im taking that as a "no dont buy the commodore radiator"
is there any specific reason bogged??

what are other blokes running??

Have a look at a NEW BF falcon rad and fan setup. I haven't checked them out myself yet so don't know if this is true or not, but they are supposedly a single fan that moves just as much if not more air then the au twin fans. The biggest benefit is the BF one is meant to draw a bucket load less amps then the twin au fans. Twin AU fans draw over 30amps EACH on start up.

Otherwise an 80 series rad with the AU fans is very hard to beat.

hey DRS, im running a 304 in my lux and im running a standard V8 radiator with a new core and a constant engine fan and normally it runs normal temp, (though i have had it off the gauge a couple of times on the beach on very hot days and its never missed a beat.

the V8s run pretty hot compared to most cars (holden say normal operating temp for this motor is 90-105), and they are a full cast iron motor and dont suffer as much as one with alloy heads.

In the V8 models, the first Commodore to have thermatic fans from factory was the VT. The VR and VS both had viscous fans still.

I think the radiator used standard will provide adequate cooling, as it was designed especially for it. And Commo parts are fairly cheap

Good luck Twon!

if money is tight then id say the camrydoor radiators as they are a lot easier to get and a fair bit cheaper too.

What are opinions and thoughts on
AU falcon radiators.

and old school HZ V8 holden radiators. 4 core etc?


cheers

i have a large 75 radiator or a large gu radiator ????? if you need one let me know .

If your after cheap radiator see the guy at Metford Radiators.

he is a old guy and last time I spoke with him he was going to close down mid-late 2008 {no-one to take over in his family}Plus bigger companies more pressure on little guys.

But he is good and cheap and quick.Will be a shame to see him go.
He`s up the back of fieldsend St near the train line.

I think the new single fans for the Ford BF have a 2 speed setup and do move a heap of air.

This is what you want

cheers for the tip!!!

where would one find these BF fans you speak of guys??
at a good rate eg not ford.

Wreckers... but there wouldn't be many crashed yet? Try some cop cars

Maybe the Hunter Falcon Dismantlers Twon.

for the record the price came in at $316.55

so i have decided to stick that idea.

cheers for the help kids. time now for option B.

Thanks for that, but ... the price for what exactly? which option are you talking about?

Falcon or commo is what I would go with, make sure it's in good nick and clean, and put a filter in it before you run the motor with it.

Coolant filters are such a valuable mod for virtually any car, I don't know why they aren't used more.

A commy V8 unit with factory thermos will definately do the job. I picked one up new from the trader for $260 still in box.

Alternatively, I had a 'stadium truck' style radiator custom made by PWR on the gold coast for my turbo sierra and it cost $1300. It measures 400 x 800 xl 38mm with an alloy core, alloy end tanks with dual pass arrangement and twin 14" SPAL thermos that move 1700cfm each Also came with an alloy shroud.




You may be thinking this is a little silly for such a small car???? Well it is. The thermos will be wired with only one coming on at a time, and if for some reason its still too hot the second will kick in on another thermal switch set slightly higher than the first. But its being rear mounted behind the cab and will have bugger all airflow, hence the large core and dual fans.
