Harrop 2300 supercharger to Optimiser 6500

[PeeBee]

Hi Pee Bee,

no the fitting at the rear on the manifold next to the super charger, for boost pressure measurement.

Your manifold must be different to mine as I dont have a fitting for boost pressure take off. I had to tap a hole in the manifold myself, and simply use one of the inlet manifold 'legs' with a 1/8" BSPP tapped hole for my pressure sender. I have just checked this now and nothing there, and would have used it if it was. Sorry. Maybe ring/contact Bullet as they supplied the manifold? If you go from the back, into the chamber, be careful regards the i/c core in there.

I rang Bullet for you. The thread size is 1/8BSP

Guys, is this how a TD42 engine mount sits, meaning relative top and bottom plates? Looks like the keeper is out of alignment with the centre of the mount?TD42 engine mount.JPG

Yeah looks off centre to me mate.

I don't even know how they can fit like that? Anyway have asked the question and will see what the feedback returns.

Tracked down the 'node' for the noisy interference on the HF radio. Its a bus bar with about 6 cables hanging off it. When i isolate the bus the noise plane drops to 1/5 instead of 5/5. Now just have to isolate the individual circuit. All the other electronic devices now fitted with snap breakers and despite them looking looking like the culprit, its something else - another goose to chase down, but getting closer, one step at a time.

Some time ago, like 600klm ago I suffered a mounting plate failure due to 2 bolts failing in tension on the 8 rib belt drive. I was assured by both Brunswick Diesel and Bullet performance this was unheard of. Well, it happened again, this time with 3 bolts failing in tension, loss of belt and boiled the motor - one dead head gasket, 30klm on north side of licola on way to a snow weekend. Flat deck towed home to Knox. Not happy. Once again, similar story from both these businesses, so I decided to first fix the bracket, which had a 2mm deflection in it, so new one purchased - no warranty as deemed my fault. Went thru 3 belts x $100 each just limping it back to the campsite, again, my cost.

So, 5 hours to get the 3 broken bolts out of the casting on the motor, 3 hours to re-tap the holes from M8 to M10, fitted ARP Chrome Moly bolts this time, drilled out the new mounting plate to suit. Increased the static idler spindle bolt from M10 to M12, drilled and tapped the plate accordingly. New spacers supplied as a set - again, my cost. Assembled everything, start car, and belt proceeded to run off, alignment issue - like, nothing has changed from what I can tell. Anyway, after a full day jinking around, threw the towel in and booked the vehicle into my local mechanic for repairs, head gaskets x 2, alignment of belt. Had to buy a gates rib belt laser alignment tool for this, so hope this is where the issue ends. @mudski swiftly supplied another 2 Fleetguard belts for me, thank you Mark. Purchased a set of ARP head studs as well to beef up the assy, bloody expensive!

So should have it back by weeks end with luck. Bee stings getting me down a bit with this saga. Neighbour across the road almost had a sale of his 200 series when i got back home from the weekend.Tow.JPGIMG_6673 (1).JPGIMG_6704.JPG

Thanks Rossco, few other changes like new bearing sleeve for the bigger bolt, another $100, cut down the sleeve bolster head and changed the socket head cap screw to a button head and increased the strength from 8.8 to 10.9. This increases the clearance on the plastic Duramax fan blades, so up from 6mm to 20mm. Getting annoyed at the constant changes to optimise the installation. These kits are generic at best it seems - at least according to Bullet Performance its up to me to make the thing fit and work - total BS. The additional bracket in the third pic converts what was a cantilever static bearing to a rigid simply supported unit. The slot showing in the photo is now a fitted hole s the bracket and roller cannot climb upwards and track off, and still allows the belt to be fitted.

Brunswick finally got back to me about the mount. yes, its splayed a bit 'but not as bad as they have seen in the past' - like how is that level of engineering comment to put a client at ease? - 'just loosen the 4 mount bolts and the centre bolt? and jack the motor up to let the mount move back into alignment' - I think this is another job for the mechanics since they have the car on the hoist - bloody astounding. ' "oh, and we are here to support you Phil, just ring if you need help'!!!
