Thanks for the compliment Rob. Yeah! Bit like Werner Altho its just a bit further & a mite more costly. Depends on time of year, but return fares are in the vicinity of A$2500 to A$3000.
So, yes I am enjoying the Forum & the info.
"--- compete with it ---" Probably NO, as apart from a once a year hill-climb just out of Adelaide & 250Km from here, I know of no other events suitable for "an old bloke in his home built sporty car"! Fun cruising on a sunny day trying not to get caught exceeding the 110Km limit will be its use. There are a few nice twisty roads not far away that one could enjoy on a 250 to 300Km "Sunday Drive"!!
Further to the pics I put on Flickr a while back. Have just added 8 more --- on the exhaust system
Will add the Dump pipe pic here as I can add a little extra info for anybody not familiar with the concept.
The Do-nut referred to was made from two pressings -- like very large washers -- in a male/female die. These are then welded together to form a pipe section ring that was about 4" ID & 10" OD. See the weld on my dump pipe. One then carefully cuts a quarter turn out of it (twice), & welds in short pieces of pipe to achieve the required shape and length.
The black finish is Hi-Temp Ceramic Coating, inside & out. This was also done to the original manifold & the Turbine housing. Cost was low, something under A$200 for all 3 pieces.
Research was done on the process before I did it.
On a particular standard Sporty car, under bonnet temperatures reached 900 degrees an inch or so from the exhaust manifold & "all too close" to hydraulic lines etc. After HTC Coating the temp at the same test position dropped to less than 150 degrees & the other lines etc. stayed quite cool.
As an extra bonus, the power output went up by several HP, "a quite noticeable amount" as it was reported !!
