I zoom therefore I am.
the RX8 will hold up wonderfully to a 55 shot. I've heard some psycho's have tried 75 shots, but that usually ends up with them begging for help to rebuild the engine after a few months.

I hear ya ...
the fuel jetting so suppose to provide the desired amount of fuel matched to the nitrous jetting (on a wet system of course a dry system would require extra fuel from the injectors).
Therefore no need to change fuel mapping.
All I can say is when it was dyno tuned by MM he felt it safer to run slightly on the rich side, combined with the 3 degree timing retard. Well at least that's what I remember. It's not much, low to mid 12 afr's
I can dig the dyno sheet up, I believe it has the AFR's on it. Got me interested now.
BTW, I also have a standard MM tune (non nitrous if you will) and with that I use the 55 shot ... runs very nicely as well.
I've experimented with the 75 shot on the 65 tune MM did for me, while the car ran awesome there was just the gut feeling of uneasiness ..... so I'm not using it that in my current setup.
Anyways things like this could be debated back and forth for years .... this is my setup ... rightly or wrongly ... car continues to perform as expected.

It probably has more to do with the fact (IIRC) that you have better fuel in your area than we do here in the SW United States. Jeff was playing a bit with the fringes in setting up your alternative map but I am not comfortable with suggesting things which are not 100% tried-and-true to my own satisfaction. Especially when liabilities can be created when I shoot my mouth off.
There is no way to see how "lucky" one has been until the engine is torn down.

I know you are kidding, Jess, but that exclamation is EXACTLY why I am so cautious and why I have chastised the rest of the BHR team for making statements of their own about the efficacy of any "shots" larger than 55.
Black Halo Racing does NOT suggest the use of nitrous oxide shots with jettings larger than .017/.032 pairings.
To this very day, I have never had a customer or associate lose an engine or manifold when they followed my advice.

Might be tempting see about driving out to the west coast so you could oversee my install.

I'm kidding of course, I know you're a busy man these days, but if things do go well for me, I'll definitely be in contact about arranging something. At the least I'm sure I've give BHR a call when I run into trouble.

BHR is the way to go .....
Ray installed my system in 2006 ... when he still lived in Detroit
That was 45,000 Kms ago ......
Car is still pulling 196 hp and 136 torque NA ....... with a MM tuned map ...
Seriously happy RX8 owner ... can't say enuf about Ray and Jeff
I should give a shout out to Todd and Eric as well ....
These guys are top notch and don't bullshit .....

I've got a dyno with a 55 shot at 226 hp
and a dyno with a 65 at 236 hp
I've not done a 75 shot dyno but would imagine it would hit 240's
The 196 I was speaking of was straight NA ..... no go go juice.
I called it an NA run because technically once you are on the juice you're forced induction.
edit: Oh and its a 6 port
