10V T pics-detonation

[JShadzi at aol.com]

Ben,

I think to the 300hp range, water injection is unecessary, of course, adding 
an extra injector or two can help take the edge off of running lean, but 
shouldn't be used to make up large amount of fuel, unless an injector for 
each runner is used (IMO).

Also, with experience from tuning my car, I am finding that detonation is 
really a timing problem, not a fuel problem.  In my car, I can tune it so 
lean that at 18psi it won't even accelerate, but advance the timing 4 degrees 
and rampant detonation.  I think it is a myth that detonation can be 
prevented with extra fuel-granted, you can dump so much raw fuel in the comb. 
chamber that nothing will burn, and a richer mixture can help cool the 
combustion chamber and EGT, but if that spark is just a few degrees too soon, 
it can trigger pre-detonation very easily.

 I'd like to know what can be done water injection wise  or  extra fueling.
 Now would be the time if I needed to modify the intake manifold, etc.
