Gunna need a bigger bonnet

[bobakers]

Hi all
Any suggestions for modding a perentie 6x6 bonnet. My thoughts so far are:
1. Try an fit a falcon BA power bulge ( would also replace the thermostat housing cover)

2. WRX style scoop (issues with hp air entering engine bay reducing flow through radiator, fugly )

3. Make a one off mould of existing bonnet using plaster of paris and after removing bonnet, fill and shape in power bulge and lay up new fibreglass bonnet (most work but could be best looking solution)

does it need airflow? and would the difference be noticable if it got it?
holes in bonnets are always a tossup..




just fyi,, the D2 bonnet has a huge no-pressure area that close to the windshield..
go for a drive in the rain and check before cutting anything[wink11]

I do like the idea of a power bulge[smilebigeye]

[rick130]

It's a water/air IC Pedro so doesn't need air.

Maybe a Tdci bonnet?

[trout1105]

Maybe you could fit a Navara scoop, They are a fairly big unit and would be an easy fit as well[thumbsupbig]

Forgive my naivete......what is this and why was it necessary? I presume something having to do with air and the turbo.....and if beneficial, would I want one?

Although I just sold mine [emoji22]

How much does it miss by? May be you could change the rocker cover to the flat one, that should give you another 15-20mm, that's what I did with the same cooler in my rangie.

mount it to the passangers side..

have you seen the canyon that exists between the inner wheel guard and the engine?

I routinely sit on the passangers side wing with my feet on the rail and starter when I'm doing valves on the 6x6,,, (its easier than leaning over)

[Blknight.aus]

I'll just leave this here....

Part shamless plug, part fun part youve got to be kidding...

This one here ended up running a puma bonnet. https://uploads.tapatalk-cdn.com/20190504/86148dca7f9ab3945025a60f5175eba3.jpg

Hi all
Sorry for the late reply, family duties today.

Thanks for all the responses, in no particular order, there isnt much room on my passenger side as I have a second battery 3" exhaust and additional electrics shoved in there. I have a donaldson powercore filter at the rear of the engine and 4" air intake on the drivers side.

Damian, couple of questions, what engine is the flat rocker cover off and would a puma bonnet fit a 6x6?

Thanks
Bob

[Vern]

That's just the standard early 4bd1 na rocker cover.
I was told that pic I posted up, they ran a puma bonnet, but I thought the 6x6 bonnet was wider?????

[Vern]

Any pics of your powercore set up??

[bobakers]

Hi Damien

Plus I've now fitted a donaldson 4" cobra head (had to lower the edic motor 1 1/2")and a 4" air intake to back under the rh guard

Bob

It's a water/air IC Pedro so doesn't need air.



Sooooo.. the intake pressured air passes thru this water block to cool it? yes?
Why wouldnt moving air make it work better?

[bobakers]

Hi pedro
The boost air passes through the core and coolant is pumped over the core and through a separate radiator.
Advantage over an air to air intercooler is its not dependant on vehicle speed for efficient operation and has better efficiency (size for size).

......but it would help slightly if the unit is positioned in a cool environment, rather than a hot environment. Same thing with the hosing.

......but it would help slightly if the unit is positioned in a cool environment, rather than a hot environment. Same thing with the hosing.May be. Mine was in the same place, my egt's dropped 70°c when I installed this same cooler over the air to air I had before it.

[rar110]

I agree, there should be plenty of room at the side of the motor in a 6x6 bay.

Hi all
Update so far:
W2A CAC mount, 3mm aluminium and mount to 2 bolts on the LHS of the rocker cover where the original cross over tube mounts and a 10mm bolt on the RHS where the crankcase vent tube is secured:
151450

The radiator was a challenge… New lower mount folded up and picks up two 10mm holes on the chassis rails:
151451

New folded up top mount picks up the original cross mount holes in the guards:
151452

Coolant pump mounts to the bottom radiator mount (also shows the new side panels):
151453

Plumbed up 2x19mm hoses and a 6mm vent line between radiator & CAC, CAC in and out temps and a turbosmart boost controller. The 6mm silicone hose was a pain to find clamps for, ended up using norma cobra clamps (had to also buy the propriety pliers which Ill also use when I build the hot water system in the camper). Boost hose clamps are Murray clamps.
151454 151463

Wiring:
Fan relay is triggered from the reverse light oil pressure switch (+) and earthed through switch in O/H console so I can switch the fan off if required (water crossings). Pump comes on with ignition switch.

So how does it go? Prior to fitting the CAC up my test hill:
Boost P = 13psi (max I could get from a supposedly 22 psi blue spring)
Boost T = 90 deg c
EGT = 650 (probe is before turbine)

Now:
Boost P = 18
T before CAC = 96 deg c
T after CAC = 34 deg c
EGT = 500

Will do some more tuning once I get the bonnet sorted. I tried a standard ford BA 3" fibreglass bonnet bulge but will need to go to a ford FG 4".

I've sourced some locking AeroCatch 4100 for the bonnet latches.

Thanks
Bob

[Bearman]

Nice job there Bob, watching with interest.

[steveG]

Nice job.
Surprising how much difference it makes to EGT with just a 60deg reduction from the I/C.
I guess the bottom line is the reduced inlet temp means higher density == lower EGT.

I may have missed it earlier in the thread as I'm only viewing on my phone, but was there a model number for the powercore filter?

Hi all

Finally finished the bonnet. Lot more work then I expected as the 4" FG bonnet bulge wasn't going to work.

Used a 3" ford bonnet bulge and lengthened the sides so I could then cut it in to the bonnet and accommodate the rise in the perentie bonnet.

Paint is concept black acrylic with a flattening agent which gives a satin finish.

Hinges are SS Defender hinges from dirk groening (no more rattle and cracked hinge bushes) and catches are Aerocatch 120-4100 heavy duty lockable catches.

The part number for the donalson powercore is D0900114.
