If you want to get technical, lets take a look at Webster's definition of
catalyst...
Catalyst:1. A substance that alters and esp. increases the rate at which a
chemical reaction takes place. 2. One that precipitates a process or event.
This is the context in which I was speaking of.

I am not a chemist but I have had a bit of experience with bigger fuel
injectors.

And all I am saying is in my opinion Bruce would have been fine with his
bigger injectors. Many other DML members have proven this time and time again.
Alan Short and Shane Baker both have R/Ts that run 14.2s and do it with stock
injectors.
