I want to take a shot at the 200 mph club. I think if I spend some time with the brilliant guys at Eurocharged, I may have a shot at it. I'm going to need approximately 7,200 - 7,400 rpm, with the super charger boost cranked up, to make that run, and some torque converter slippage. Does anyone have any experience spinning them that hard??

I'm not too excited about blowing an engine at 200 mph. I'm thinking this may be my last racing hurrah, but I don't want it to be MY last hurrah!

 

At 7k the supercharger will likely leave the car before you do. That is too too high rpm, that is why I designed the pulley saver. Woody

 

Well there always has to be a party pooper! I appreciate your feedback.

Have you ever actually seen an SRT6 supercharger come apart? Do you have any idea what would be the maximum RPM the supercharger could live through? I have an overdrive pulley on mine, and I would have to calculate the ratio to computer the actual supercharger RPM.

Thanks,

 

I seized a supercharger after an extended (20-ish miles) high speed (120+) run on the highway. I was running the 181 crank and C3 upper pulleys.
At 7,000 RPM, if it can be done, you'll have to have the fuel system to support it too. Here's a chart that took rpm up to 6.500rpm using the various pulleys available.
Good luck!

 

Thank you sir! That's good information. The COVID-19 pandemic screwed up my plans, so I just back burnered the idea last year. I may circle back around and take a run at it whenever the ugly bug gets under control.
Thanks,
