Could you elaborate more on which car this was?

I believe it was Berk Technology (IIRC) who ran several time attacks in their 135 with the following upgrades , as well as several other shops like Top Speed In Atlanta which swept One-Lap in a GT2 and AST with these mods. Although they do run hotter, as most all turbo cars do, I never saw at the track/talked about/read about "issues" that preventing it from running 25-30 minute sessions once upgraded and I have been on track with some of these guys. Granted turbo cars always run hotter, these cars could still run in July heat in 95+ temps. I'd like to ask how the cars do on the track for longer time periods though as Berk did use a vented hood to keep it cool out in the mid-west summer heat and never updated their blog on if it was enough to keep it cool for longer durations.
The 1M has gone 8:12 on the Ring and I'd doubt BMW's own cooling upgrades for this new model are as substantial as the beefy aftermarket mods that are available for the N54.....
I think its safe to say don't plan on putting a PROcede on your 1M and expect to walk away from E92 M3's because it will have cooling issues without significantly addressing the cooling system unlike an N/A M car

As far as 1M vs M3. 8400rpm vs turbo motor. E92 M3 sound/experience IS a work of art, while F.I motors just feel like a wall of torque to me (yawn, it's always more fun to work for your power and hear the reward)
A 7200-7600rpm turbo motor with a higher peak power curve would've been a nice compromise. Also the high roof line on the 1 relative to the rest of the mass (higher center of gravity) hurts the 135 as a good base for a track toy. It's great that the 1M now shares a carbon roof but i'd still put my money on the E90/2 being a better chassis to go tracking with simply for where the weight is
