Popular Post Rhubarb77 Posted March 30, 2019 Author Popular Post Share Posted March 30, 2019 From the very beginning my Bosch 044 pump suffered from cavitation. Sounds like glass beads getting smashed up inside the pump. Well when the fuel pressure fell over on the dyno and it was time to go twin pumps, I emailed GRP4, the tank manufacturer and asked them if the -8AN outlet would flow enough to support two pumps. He was good enough to be honest with me and explain the the pick up pipe inside the tank has a kink in it and would reduce flow. I had no idea it would be this bad! Needless to say this was causing massive flow issues and is a testament to the durability of the mighty Bosch 044 pump. After careful planning and acquiring all the parts to complete the job, I took the tank to Drew at ARE Cooling in Brendale where he cut side of tank open, welded on a -12AN outlet and 1" pick up pipe. -4AN fittings where the fuel sight gauge used to be and tidied up the welds where my fuel sender goes in. The car is back running and the pump is actually QUIET! I will get the second one wired up soon, the ECU will switch it based on manifold pressure, as a guess it will come on around 18psi. 10 Quote Link to comment Share on other sites More sharing options...

Rhubarb77 Posted May 10, 2019 Author Share Posted May 10, 2019 Back to the dyno today after sorting the fuel system. Made 355whp @26psi. It's safe to say an 11sec pass is coming up 7 Quote Link to comment Share on other sites More sharing options...

Rhubarb77 Posted June 8, 2019 Author Share Posted June 8, 2019 Another cruise session at Lakeside a few weeks ago and unfortunately the gearbox failed. It was not catastrophic so I was able to drive the car home 10 mins from the track. I used the dropped crossmember method to remove the gearbox which worked really well. It's been shipped interstate for a rebuild and I was told on Friday that the gears are all good but bearings are shot. Heavy duty needle roller bearings will be fitted as part of the rebuild. I'll be using Redline MT90 oil this time and have sourced a heavy duty transmission mount keep things supported a bit better. Thanks 5 Quote Link to comment Share on other sites More sharing options...
Rhubarb77 Posted July 25, 2019 Author Share Posted July 25, 2019 I would not recommend this transmission mount, poor fit onto the gearbox extension housing (I needed to cut the tops off both mounts and weld the old top plate onto this one) and so much noise and vibration through the car so I put a standard mount back in, much better The ignition leads have been replaced after it was found they were causing a misfire on hi boost only. And I've finally sealed up some minor but annoying leaks from the thermostat housing and rocker cover using better products. Loctite 515 on the thermostat housing gasket and ThreeBond super sealer on the rocker gasket. It's a 2L rocker cover on a 1.6 head I don't know if that's why it's always leaked in the past?? The rebuilt gearbox is back in and the car shifts much nicer now especially with the Redline oil in it. 6 Quote Link to comment Share on other sites More sharing options...
Popular Post Rhubarb77 Posted December 15, 2019 Author Popular Post Share Posted December 15, 2019 Woohoo. Dipped into the 11's last Saturday. The bias ply slicks performed amazingly!! Chopped 0.3sec off my 60ft and 0.5sec off my ET. One of the runs at 121mph. I had read horror stories about mixing radials and bias ply so after making lots of calls and taking on advice I ended up with a set of used Avon ACB9 5x22x13 bias ply formula ford tyres up front. The car ran straight as an arrow on the strip, a lot more stable than previous runs on semi slick radials. 10 Quote Link to comment Share on other sites More sharing options...
Rhubarb77 Posted June 9, 2020 Author Share Posted June 9, 2020 The fuel pressure sensor has been connected for a while now but I had been putting off oil pressure until last weekend. I got stuck in and mounted this EFI hardware sensor block on the inner wing. Moved the fuel pressure sensor over and bought another for the oil. These are Variohm 0~150psi sensors. The lines are 3AN braided teflon and stainless hose ends. The loom wires were only long enough to reach the sensors if I mounted them pointing down. 1 Quote Link to comment Share on other sites More sharing options...

Rhubarb77 Posted August 8, 2020 Author Share Posted August 8, 2020 Drags again last Saturday. 11.7 @ 121mph. The photographer captured some great shots of the tyre wrinkle. I'm making some cosmetic changes to the engine. Rocker cover painted in 2K same colour as the body, Olympic blue. The inlet manifold, turbo inlet pipe & bov pipe are getting powder coated satin black, I will have them back next week. Really happy with how the rocker cover turned out. 1 Quote Link to comment Share on other sites More sharing options...
