My roadrunner with the Procharger will be back together this week. The 528 Hemi that was in the car when I got it wont be back from the machine shop till next year sometime. So I put my mild built 383 in it for now. Plan to start it up with Holley 670 standard carb, no blower. If the trans, 46RH, which I got back today checks out and has no issues I will put the blower belt on and switch to the blow through carb. I put a 5" pulley on the Procharger, I expect the boost to be minimal. The car has a water/meth system on it. I would like to use it to keep the intake charge on the safe side.
I saw that episode of Engine masters, and several episodes from Richard Holdener doing W/M testing.
My take away from all I have learned so far is this;
1. Water Meth does not increase horsepower, it can actually lose power when used without tuning the engine for it.
2. Water injection alone does a good job of cooling the charge temperature. Can be helpful to stave off detonation and keep the engine alive. Does not increase power at all.
3. Water meth together cools the charge temperature and raises the octane level along with fuel enrichment. Again, the engine has to be tuned, leaned out, to remedy the rich condition, and timing optimized for the higher octane level with the additional alcohol fuel.
So what am I missing there?
My system will bring in the WM at a preset boost level. Boost will likely not be enough when idling for sure, and maybe cruising to bring in the WM system. So how should I tune for it?
