Less...went back to this mornings news readings...
This is what am talking about ONLY and OEM can do the right stuff to the whole engine design...3rd parties can NOT afford to cast a new engine block, heads, etc, etc...
2019 Chevrolet Corvette ZR1 First Test: Out With a Bang
Notice the references to 'heat'...a major issue when stuffing or force feeding any ICE. The bigger the block...the more heat rejection surface area.which is notoriously prone to power-sapping engine-protection mode due to excess heat
andand there are four new heat exchangers (13 “radiators” in total) tucked hither and thither
Boils down to BTU density, thermal mass' ability to move that heat and the ancillary stuff that goes with this common issue...thermal management and the designed in safeties that are mostly based on thermal metrics
And towing heavy is way harder than any sports car, drag racer, etc...as how long do they stay WOT at GVWR & GCWR ??? Add in on inclines 'some times' to 'often'...
Thanks Ben for the detailed response regarding the need to upgrade ancillary components to handle the increased stress, heat, etc. on these components.
It sounds like the engineers did the job right when it came to component upgrades necessary to handle all that power in the new Corvette...GM's flagship and world class competitive super car, IMHO.
As you have said in the past it's not so much the engineering talent where problems arise, but the bean counter factor...where inadequate parts will occasionally surface and surface due to initial concerns about 'cost'.
IMO again, I feel that it is more likely that parts that have, say less margin of 'robustness', come to the fore in vehicles that are not corporation flagships and less costly.
