30 sty 2019 · Racing and performance engines need stiffer valve springs to reach higher rpm without floating the valves and can see closed spring pressures of about 200 to 300 psi, and open loads of 1,000 pounds or more. Just looking at a valve spring won’t be enough to determine if it’s bad.
16 lis 2013 · Valve spring material is not one fits all, but cam and other things play a part. Brodix springs and products in general are very good. Just depends on style of racing and cam lobe. Heat can be a factor in material.

I'm sure deeper analysis of the fueling and trims would show a problem but it was not enough to trigger a warning of any sort. I could always try a map from a newer model if it did indeed present a fueling issue.
Valve springs are responsible for properly controlling and seating the valves at varying RPM’s and operation conditions. Proper installation of the recommended Crower valve springs is critical to achieving optimum perfor-mance and trouble free operation.
Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. Use the only valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift.
8 wrz 2016 · Race engine builder Jon Kaase warns, “When the valve-to-lifter assembly leaves the cam lobe on the opening side and comes crashing down on the closing side, this affects the entire valve train particularly valve springs.
21 kwi 2020 · An in-depth look at the tech revolution that lets valvesprings survive over 1.00-inch valve lift, run over 12,000 RPM, and withstand millions of opening/closing cycles.
