Safe boost levels?

Already running a uprated FMIC Brian and the water injections on there now just starting to tune for it at the moment.

Then as long as you can tune there is no limitation to running high boost. An egt gauge is quite useful especially when running higher boost. A good intercooler will drop charge temps, a good water injection setup will drop combustion temps, and the rest of running high boost safely comes down to ignition timing and afr.

im defo getting egt sensor and wideband on my fc to keep afr in check and for diy mapping.
100mm thick ic going on with big ali piping, i dont have water injection yet though,
weve started looking at the 50mm custom runner inlet manifold today at work. the 4- 50mm pipes will just squeeze in std plenum with the original runners cut of.
the only thing im not sure about is the injector positions on custom runners.
im thinking of pluging the 2 inector holes in the intermediate housing with cast iron plugs so I can port the inlets a lot bigger by going up more where the injectors used to be- ie the same square area as the secondary inlet ports. then flow and volume will be exactly the same through 4 identical bridge ports and the four runners.


which will flow more air ? a hks  t51r
or this:-

I think the hks t51 would flow more, best way would be to compare compressor maps.

Kev,
      Remind me before Saturday to bring over a bottle of that water I was on about for you. I\'ll take some more samples and print off the results for you to check for yourself. Failing that you could just drink half a pint and if you get the run\'s then you\'ll know its good for your "WI" :rollin .
