600 whp for the last 100k miles on RB's. Have send them once to Rob for inspection half way, he brushed and gave them some free love and they were still good to go. No rebuild required at that time.
Ron 100, bit of meth and some good oil.
No experience with Hydra, but with RB: very good quality product and service that meets that quality. (Very blessed that I never had to replace some crapy turbo's that would decrease my trust in the car and cost me much more over time)
Car is used and abused on race tracks but also participated in two cannon balls rallies and endless amounts of trips on the German highway, while driving 200+ for multiple hours without an issue.
