For my next oil change I'm switching over to a GTM 34row cooler, they have the best price for the biggest core. GTM's 34 row cooler is listed as 13X2X10.25 = 266ci. The Z1 Cooler is listed as 13X1.25X10.25 = 166ci.
The question is...is GTM's core really that much bigger or is there a typo on their website. Can comment on this? GTM?

GTM uses the series 6 Setrab core which are all 2" thick. Z1 uses the series 6 Setrab core as well so it should also be 2" thick, I believe that is just a typo.
I have the 72 row series 1 and if I keep the RPM's above 5k continuously with lots of full throttle then the temperature slowly climbs to 260F after 30 minutes in high ambient temps. If you back off a hair then the temperature stabilizes, if you go up a gear for a lap then the temperature does drop a bit.
