Perhaps a solid (no holes, no slots) lightweight crank pulley is worth a try, something that we have the ability to produce for race use - going past 7500rpm.
For street cars, our regular Underdrive Crank Pulley and NST CR-Lite Crank Pulley should be, and have proven over the years to be, sufficient.
Best of luck with all your projects!
