2020 Raptor 700
Anyone bought a BP Racing 47mm throttle body? Was wanting to know if this was truly a 47mm with new butterfly valve or if it is just tapered with stock butterfly?
How much difference in performance should be between the stock TB bored to 47mm with stock butterfly and a true 47mm TB with 47mm butterfly?I looked on eBay second ago and the one that’s $120 said in the description it’s a stock bore that they taper when you ship them your tb. The one that’s $283 says in the description it’s a +3 butterfly and the whole housing is included, no core refund. You’ll have to sell your stock tb after to get some money back.
