Terrific and educational reply!!
@x25
Thanks for taking the time for your very detailed and again informative response.
Although the whole of your comment is quite insightful, you really put things into context with this sentence - Using the kit, you also end up removing the oil cooling job from the radiator. This is actually very important, since coolant temps usually determine the ignition timing (of) your engine ... –
Fortunately or sadly (from my side of the fence its debatable which one qualifies) none of these two cases apply to my vehicle at this time.
Right there, you identified the one single issue which might by itself justify undertaking this exacting project on the LS3 CAMARO if it were used either as a daily driver (with ultimate goal to prolong engine/components life) or if it were to see track/autocross duty.
Paraphrasing the late Richard M. Nixon, as I read your reasoning on this subject two things become perfectly clear: you have truly analized this subject for quite sometime, and you know the trade offs on this mod back and forth.
Not having even a third of your knowledge on this subject I do concur with your conclusion that we already have a very well developed engine in the LS3 and though further improvement is still achievable we are really talking about fractional, maybe even marginal gains.
Is quite unlike the LT1/LS1 we got on the 4th Generation F-Bodies in which there was a lot to extract, many times quite easily and cheaply too.
I’m going to start planning and go apply your final recommendation : replace the radiator with a larger displacement unit and switch the coolant mix.
Again, I really appreciate your kind advice in this subject.
All the best with your project and I hope you finally gather the data you seek to get definite answers in this issue.
All the best,
The Flash
