GREAT INPUT EVERYBODY ! HERES A LITTLE HISTORY TO WHY IM ASKING, I RACED STOCK CARS ON & OFF MY WHOLE LIFE, AT ONE POINT I DID NOT MISS A SATURDAY NIGHT AT THE TRACK FOR 17 YEARS , WON A BUNCH OF RACES , ALL WITH RACE FUEL, NOW THE MODIFIEDS HAD $40,000 HIGH COMPRESSION ENGINES, I WAS ON THE CREW OF ONE, & HELPED SEVERAL OTHERS , NO DOUGHT USING RACE FUEL , SOME OF THE OTHER DIVISIONS LIKE STREET STOCKS ARE LIMITED TO 9.5 :1 COMPRESSION, & 2 BBL. CARBS. BUT ANY CAM YOU WANTED, 30-40 STREET STOCK TEAMS PUT RACE FUEL IN THERE CARS EVERY SATURDAY NIGHT , MOST INCLUDING SOME OF MY OWN ENGINES WOULD LAST A WHOLE SEASON BEFORE A REFRESH , NOW I FIND IT REAL HARD TO BELIEVE THAT INSTEAD OF RUNNING RACE FUEL & 40 DEG. FULL ADVANCE IGNITION TIMING , THAT I COULD OF RUN PUMP GAS & RETARDED MY TIMING TO WHO KNOWS 20 DEG. & WENT FASTER, I AGREE THAT "SAY BOTH CARS AT 20 DEGS. 1 WITH PUMP GAS & THE OTHER ON RACE FUEL ,WOULD NOT MAKE A DIFFERENCE " BUT THE 1 WITH RACE FUEL I COULD ADVANCE THE TIMING TO 40 DEGS. & SMOKE THE PUMP GAS CAR" THATS A FACT ! I'VE RUN RACE FUEL IN EVERYTHING I'VE HAD SINCE I WAS 17 YEARS OLD & DRAG RACED USING MY FRIENDS DRIVERS LICENSE BECAUSE YOU HAD TO BE 18 YEARS OLD TO RACE IN NEW JERSEY, & NOW IM 45 , MAN I'M GETTING OLD "LOL" , ITS IN MY SNOW BLOWER-WEED WACKER-LEAF BLOWER-GENERATER , RAN IT IN MY SKI BOAT I HAD FOR 14 YEARS WITH A PRO-V 150 YAMAHA OUT BOARD ON IT , 4 OTHER MOTORCYCLES , 3 DIRTBIKES , 2 QUADES ,HELL 15 YEARS AGO WHEN I BOUGHT MY HOUSE I BOUGHT A TORO LAWN MOWER GUARANTEED FOR 2 YEARS TO START ON THE SECOND PULL IT STILL DOES ! 15 YEARS OF RACE FUEL NO STABIL-NOTHING , MY V-MAX IS THE FIRST THING I WAS NOT RUNNING RACE FUEL IN , & IS THE FIRST THING I EVER HAD WITH CARB TROUBLE ,THEY ARE FIXED AT THIS POINT ! THATS WHY I WANTED EVERYONES INPUT, I TAKE CAR ENGINES APART FOR A LIVING , WHATEVER ADDITIVES THERE PUTING IN PUMP GAS TO KEEP ENGINES CLEAN IS NOT WORKING !!! INTAKE RUNNERS & THE BACK SIDES OF THE VALVES LOOK LIKE MY BABEQUE GRILL "LOL" PS. I'M NOT YELLING AT ANYONE I USE CAPITAL LETTERS BECAUSE THERE EASYER FOR ME TO READ !!!
