great product

Summit RacingSummit Racing Verified Purchase

works perfect , has 19 full turns open to closed , takes 9 turns on my car to go from 11.09 to 11.50 in good air , only 7 turns in summer - worth every penny. p.s. add a dab of loctite to the threads to hold the adjustment - tends to vibrate towards closing about 1/4 turn per run otherwise
