Be very very careful with temperatures as .100" makes them a bit too thin and they crack around the spark plug through to the water jacket as I have never seen one get down to 39cc. Also if you are using a 2lt inj casting they make much better horsepower without any filling etc to the inlet port with most of the work being done to the roof to increase the port volume and a lot of work to increase the port volume on an aluminium manifold as air speed is never an issue Most of the is needed on the exhaust to be able to get the air out
Thanks Danny I've ran the old head at 0.100" for many years without trouble, hoping it will continue. I have ground the sharp edge away from around the spark plug holes, should help with any cracking issue. Will have to wait and see if my small port head works.
Waiting for a few bits to finish off assembling the engine, so got back onto the brake upgrade. As I had to go to 15” for our control tyre, there’s no point in leaving the old E30 / Volvo brake package in there. After trolling DBA’s web site, I came up with DBA5040.1S for the front (296 x 28mm) Holden VX and DBA2882S for the rear (284 x 22mm) BMW E87. Also found some Wilwood’s that don’t look like hydraulic hinges and were mighty cheap (must have Scottish blood in me…)
Machine up some hats for the front (more of a flat disc) and redrilled the rears plus added sleeves to suit the Hilux axles.
Hey Clayton, Love the machining but what's going on with the colour of your suspension, you have a bit of wog blood in you. I used Alcon up front on my Escort to keep with 13" wheels, rubber is cheaper. All about racing on a small budget. Darrin
Got the manifold back from the ceramic coaters and none too happy with the finish on the flanges. Looks like they put way too much on and it ran, will have to block it back to get a good seal for the o-rings.....
