Choosing compression ratio

[Barry]

Ive got a bottle heater already, and already have a way to retard timing. I have the nitrous spray directly at the IAT sensor, and have it tuned to pull timing when it gets below a certain temp.

Thats creative. My concern is that the time it takes for that sensor to react and to pull the timing. Somewhere I read that that is a very slow sensor, or maybe that was a MAF iat sensor...

I have my performance enrichment throttle position set low enough that it doesnt give me a problem. At 50% throttle it starts giving it more fuel, and the spray wont come on until 3300 rpms and full throttle

how much did a set of pistons cost from JE?

nitrous doesnt effect your cr it just has more oxygen in it then air so u can dump more fuel in and get more hp so its about tuning
