Default Re: manual trans and clutch quaetion

I agree with Sean, I wouldn`t mess around with trying to make a non adjustable street clutch work on a drag car. In addition to my old stickshift Stocker Mustang, I have been racing my 78 Fairmont for over 35 years, the past 24 years with a stick. I ran Jerico DR4s most of that time, and have had a G Force G101A for the past 5 years. I have been using McLeod Soft Lok sintered iron clutches since 1998, and typically can go at least 2 full seasons (typically 75 to 100 low 10-high 9 second 1/4 mile passes per year). In those 24 years, I broke my Jerico 3 times,( 2 were about $300. for parts each time, once was much uglier), and I have yet to hurt the G101A. I do not have a data logger, and I have not had much need to play with counterweight, as my launch and shift RPMs are very close together, My Fairmonts Soft Lok is a 10" sintered iron disc with an aluminum flywheel, and I normally start with about 450 pounds of base pressure when new, and I am hardly "always messing with spring or counterweight adjustments ". I don`t run my clutch on the ragged edge, so I MAY adjust the spring tension 2 or 3 times a year (a 5 minute job), by 1/4 to 1/2 turn on each spring, and keep an eye on the freeplay. Other than that, it`s add some gas every 4 or 5 passes, check the tire pressures now and then, and if hot lapping, maybe charge the battery once or twice . Pretty low maintenance deal. Also, in the 24 years with the stick, I have never hurt the rearend yet,
