I ran an aluminum American Turbine AA for 2 1/2 years with mine. Get a droop,get an extension, buy mine. You need the droop if you are under 90 or so to get the lift, after that a straight will work too, They are just too pricey for me right now, I've got other things to do first. NOTE: the more HP you give a Daytona the better they work. TIMINATOR
