Let's find out for sure what the coolant volume is for each radiator.
Let's take this to email or PM since we seem to be the only 2 people interested in C6 performance. Somehow the topic changed to Fords.

I then did a C6 at 3400#s and a trap speed of 114 and got 393hp.
Chevy claims a 115 trap speed which brings that to 403hp, but VERY FEW people have trapped 115 in a STOCK C6.
Then again, there are alot of NEW Z06s trapping 122-123 and some at 126-127.
Just some info to think about.

skill driver + good DA (sea level & good weather) + good track preparation + NO TIMING RETARD from coolant & iat, (please, i don't want to turn this into a TM debate) = 115mph
since i never get good DA due to elevation, i always corrected it to sea level just to get an idea. if you were to do that and use the correct trap on the horsepower link you will find your car is closer to 400hp then 358hp. here is the link if you want to correct it to sea level.

it is my understanding the the tranny cooler uses a seperater smaller radiator just for the tranny.
you can add one or both to the base or f55 pretty easy.
transmission cooler $64.99

did they section off part of the radiator and pump the trans. and oil through the same core. are they using the same 'core' but pumping three different fluids through it ? antifreeze, trans. fluid, and engine oil ?
does the z51 use a larger 'core' radiator ? different part numbers, etc.
would a base or f55 owner be able to use a z51 radiator and plumb the additional lines themselves ?
sorry, didn't mean to get off on this topic. was interested in the 'stock' results reported.

again 06 service manual, page 7-269 shows the trans oil cooling lines goes into the passager side radiator. on page 06-628 it has a section on "engine oil cooler replacement - auxiliary", in that section it show a separate oil cooler that i don't have in my z51. the only thing that i can think off on this section is, it is a dealer add on.

Only the base/F55 manuals did not get the transmission cooler.

That is correct and why I get a chuckle out of the "coolers add extra weight" statements sometimes heard here.

It was the color matched handles that reduced drag to get those numbers!!!

good to know....
learn something new everyday.
i didn't know that all automatics got the coolers. and that only the manual z51 got it stock.
i wonder how hard it would be to 'retrofit' to an mn6 f55.

tranny coolers are gonna help keep the 'shifts' crisp and consistent.

Tonight, I let the car cool down for an hour+, outside temp was mid 50's. Spun the tires just enough to clean em off, left at idle with no footbraking, car dead hooked all thru 1st, trans left to shift itself in 'S' mode and TC/AH off.
Nothing has been done to this car except an oil change, a Z06 spoiler and color matched door handles.

this is a Grand reason why the Vette appeals so much to me....

agreed, that's why i was under the impression that the z51, automatics, had 'additional' coolers, not just the 'standard' method, via the radiator.
