I like their talk of turbo speed, not many cunts measure this, its how pro's talk and do things
I am near the end of my turbo's range running it at around 118,000rpm (comp map only goes to 120,000rpm) but fuck it I'll push it a bit beyond LOL, all these things are under rated for safety LOL
I rekon you can run the poofter to 140,000rpm not a problem.
