So, brainstorm while cleaning.
Take na engine, boost, and tune to run on the new boost.
Add intercooler.
Add nitrous.
Add meth injection to further reduce charge temps.
Re-tune for ALL at the same time.
Is it too much? Or has someone already done this? Seems like it could work for the challenge.
Nitrous, meth, and boost on dragstrip. Boost with meth on autocross.
Low boost for everything else.
What sayeth the hive?
I'd drop the static compression a bit with a thicker headgasket, then combine the boost and intercooler as one step.
Then, once that is tuned on pump gas, look at creating a tune for E85 along with a way to either have a separate fuel system for that or add a sensor to determine the amount of ethonal and allow the EFI to manage the switch over itself. Depends on how smart your EFI solution is. With E85 you can raise the boost level to compensate for the low static compression.
Nitrous can be added as a final step, especially if it is a wet system as its fairly self-contained and only used for the drags, which is the last event before the concours, so if you blow it up after making a couple of passes without it and then while tuning it, you'll be fine.
Honestly, while that's a lot of stuff to throw at an engine, if you manage the heat properly and slowly raise the boost and nitrous levels while watching the data logs, you should be able to headoff any major catastrophies long enough to make it through the Challenge.
