I am looking to put a petrol swirl pot,uprated aftermarket fuel pump and uprated adjustable FPR on to my FD.
My question is does a rotary engine suffer the same way as a boinger with bore wash?
I cant find any information anywhere on it.
Thanks
Dan
I think they do as the lack of oil on the housings after the engine has flooded is what makes it hard to start (yes?)
Dan,
I know you asked this question a while ago. Do you mean - can you completely flood the chamber with fuel?, causing a hydraulic lock? or hydraulic explosion in the engine?
If this is the case - I have never heard of it happening in a rotary. I have seen it happen to plenty of Top Fuel drag cars - the whole block explodes.
Let me know.
Flooding is that you cant start the car in the first place.
Bore wash as I am to believe is something that will looses compression, and then makes for a rebuild. I think it either burns the piston rings out, or it glazes the bores and the mix of fuel/air brushes past when on the compression stroke.
I know that our engines run on the richer side of life, and the oil fields love us to bits. But can you add to much fuel?
If you add to much you loose power, which then comes down to mapping, using both EGT and lambda probes, idealy one per port. They say that the back rotor gets hotter, so add a little more fuel to cool it down. :)

I understood bore wash to be a result of petrol running past the poston rings and displacing the oil lubricating the skirts of the piston (which sort of gets there by chance in the first place).
I guess this doesn\'t really apply to a rotary, because the oil seal is mugh better (being a continous seal), and the oil to the sides of the rotor is better suppiled.

you cant get bore wash on a rotary. as tsh said its where petrol washes the oil off the bore. the rotary injects it in with the fuel so no probs:D
