upper boost limit for stock MC-1 internals?

[Ken Keith]

Right on, that's the info I'm looking for.  So, the cracking (and I 
assume warping too) problem would be due to the crazy underhood 
heat.

25 psi.  That's very cool.  I'm interested in what incremental steps 
are involved in ensuring proper fueling.  Meaning, what can be done 
with the existing CIS?

I'm thinking that 15psi isn't so outrageous for a target street level.  
Specifically that level, will something other than nothing need to be 
done to/with the CIS?  Is it capable of supporting 15psi?  Would 
new, stock, injectors or something like that be recommended?

Thanks again,

Ken
