Gunna need a bigger bonnet

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:
Attachment 151450

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

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

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

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

Nice job there Bob, watching with interest.

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.

Bob
