Default 30% vs 20% byrons

I have been running byrons 30 gen 2 fuel. I want to try the 20 due to cost and engine wear....

Is there that big of power difference????

Most of the Italian motors are designed for 25% because that's what they get in europe. I like the Byrons 25%. Plenty of power & no re-shimming the head. Most manufacturers advise adding a shim for use with 30%. I have not run the NEW Byrons yet but if there is no 25%, I will shim all my motors & run the 30%. You can feel the the difference between 20 & 30% if you run them back to back but if you cannot win with 20%, 30% will not make the difference.

So how about this Gen2 fuel? Is it all that it claims to be? More run time, lower temps, better lubrication, easier tuning, etc.? Sounds too good to be true. haha. Just looking for first hand experiences or thoughts on it.

I run a track in MAss. An I have been running Byrons now for years 15 to be
exact. And you won't notice a difference betwwwen 25% and 30% but you will between 20 and 30% . The tune will be rich when you go from 30 down to 20. The cost savings far out weighs the perfomance gains.

If you use the 30% and see faster times than with 20%, than OK, go with it. If not, then stick to 20% since its cheaper and will make your engines last longer. In offroad, its not more open, but onroad guys have some limits with nitro content.

I ran the Byrons 25% gen2 last weekend & I noticed on both engines(RB C6 & RB S5) I had to lean the the top end about 1/4 turn & lean the bottom a tiny bit. They both ran very cool (on a cool day) & had good smoke. I did not time my tanks so I don't know if I got longer run times or not. So far it seems good, time will tell.
