thanks now i have a ref. point , i was at the nbssr radar runs and ran my 600 srx with this helix at 102.8 in 2000 ft. and although it was enough to win the trail stock class it was hanging at the gun and i held it down for a good 500 ft. past the gun and it was just getting going on the mph gauge. it was too late i was not set up the way i would have liked .
