That is exactly what I thought would be the problem, and a big worry! Is there a maximum retard figure you can go with? Ok, correct me if this wouldnt work, but could we possibly make it work indipendantly of the engine, so the spark and fuel needed for combustion for anti-lag are stand alone (plug just before the turbine, fuel added just before EGR valve), and therefore not needing to change ign timing at all, or am I missing something here?

As title. I have done this with great sucess on normal 4cyl lumps, but I am not sure, due to the engine design, if this is even possible on on a Mazda 13B rotary lump. With the spark plugs on the opposite side to the exhaust ports and effectively in a different chamber, I'm not sure the ignition retard side of it will work? Does anyone have any info/experience with this? Does WRC style EGR anti-lag need the same ignition retard issues? I dont know about that setup as I have no experience of it, but could this be a solution? I don't need to conform to any regs as this is a sprint car in an open series, but how I should implement this I do not know. Any help would be much appreciated Thanks
