X Charger With 42lb Injectors
I have read that you could run a rotax racing ecu with a riva stage 3 supercharger and 42lb injectors with no problems, Can you do the same with a x charger? Thanks

Hi Vic, not with the X charger. You will need the RRFPR to run it safely.

The S3 SC + ext. IC combo is a tad lean at WOT with 42s, but still considered safe (probably in the area of 12.5 lambda). The "X" SC is reportedly stronger than the S3 SC, so it crosses the threshold of safety. The RRFPR has to be one of the best solutions available for the 4-tecs.

Yes but what about if you are running the X charger with the stock IC 215 modles???

Thanks Jerry I was asking coz another member has this setup and i had replyed. Was trying to help him to get the answers he needed. You already posted on the other thread tho. Think I am going to go with the X charger and RRFPR. Will this be ok on my setup so far? Apart from tweeking the prop? Thanks R88

Yes, it will be a good setup. You will need to add pitch to your impeller though.
