The 13B NA Power Thread.

If they maxed 4 460 cc/min injectors out on the dyno, and made only 197 whp, they either had the parking brake set or were running way too rich to make peak power.

The numbers will not be that close, I really doubt that a 25% thermal efficiency can be achieved with a stock turbo and safe tune on a turbocharged rotary.

I have seen 30% (calculated) on an NA rotary.

AFR was at 12.8 : 1, which is slightly richer than where I would've have put it.
