My apologies, I have the original Turbine Core with the turn down, not the II.
It’s a healthy 310 with all of the expected engine mods. I’ll try to repack my current Turbine Core again and see how it performs. Is there a ‘best’ packing material to use to help with the sound?
Yea… I’ve seen pictures of the extra long silencers. I’m not a fan, but if it’s the route I have to go to race then it is what it is.
The other issue is the technique that the series used to measure the dB. Im going to contest it and provide the specific sound testing rules and techniques from the AMA. Hopefully between a better technique and a fresh packing, I’ll be OK. I do get a ‘warning’ my first race, and so long as I’m taking actions to improve the sound level they’ll let me continue racing. I’d like it to be a none issue, though, and get below the limit, if at all possible, to not worry about it anymore.
