Stock injector size?

I'm too lazy to check, and it's late, What's the stock injector size on the re-egi, and, who has the record for most power out of the stock re-egi setup w/ afm?

Would that be 430cc primaries with 720cc secondaries?

holy crap. So two 720s then. yikes


So does that run out to be enough fuel for 246hp at 80% injector duty cycle, or does it work differently for a rotary?

Nowhere near enough for 246 hp.

Edit: You could use this I suppose, and put 0 for secondary injectors...

gah, ok... so I guess injector sizing works a little different... care to share?

At what point would I start to lean out?
