Well my Demon picked up almost 8 tenths in the 1/8 with the 47n/53f jets for 6-7 yrs and never had ring problems but I did not spray it every pass. I was using a 5500 8 in. convertor, 4.86 & 5.13 gears probably 3400 lbs, stock interior,bench seat. I wish I had run a smaller fuel jet I might have made a 5.99 pass if it hooked.
My goal is to run a 5.99 pass in my D-50 and it is faster on motor than the Demon was on NOS.
1.33 60 ft,6.21 at 110.59 in the 1/8, pump gas small block,2950lbs,drag radials,mufflers and driven to track ...
