Drag racers have kept their motors together for decades with more voltage and rpm, it wasn't to keep motors together, it was to keep motor and brush wear down. The average guys couldn't keep up with a 10 turn spec modified class, can't keep up in a 19 turn spec class, and can't keep up in a stock spec class either.
There is a class for people to start racing in, its called novice class, and its also the lower mains in every class, remember what qualifing is for? To seperate the drivers by their ability. If new racers are getting intimidated, its because the track dosen't offer a freindly atmosphere to new customers, its because the average seasoned racers are running them over. When are the pro's running over racers? When are the pro's setting a bad example and making racing look bad? For the last 24 years I've been racing, everybody has looked up to the pro's and aspired to drive like them.
Their are plenty of means to encourage and promote entry level drivers, blame the track owners for the lack of that. The pro drivers make stock class look good.
