So..... This base model engine makes more than the C7 427...??
And it only traps like 123 in the 1/4....?
420 whaaat????
???

I think you are talking about the C6 LS7. Regardless, a bad ass motor. If this article is to be believed GM has figured out a way to produce and warranty a 6.2 NA motor that makes +50 more than a Katech built LS7? No way.
Pretty sure the IMSA spec is a 5.5L LT based engine. Been a 5.5L limit since the C6R.FWIW The Gen V 6.2 GM used in prototype/IMSA weathertech racing makes 600 hp. That said I don't think GM is sneaking those into the C8 press cars. The factory motor has to pass emissions and run on pump gas.

They are often restricted by throttle inlets, etc, in an effort to limit power or torque for BoP.
Theres multiple classes in IMSA, the prototype class makes more than the GTLM class (thats the class the c7r and c8r are in). all restricted to 500-525hp, somewhere around that ballpark.FWIW The Gen V 6.2 GM used in prototype/IMSA weathertech racing makes 600 hp.

I dont think they ever used a 6.2. Cadillac racing is different from corvette racing.The new motor from 2018 up is 5.5....2017 is last year they used 6.2 GEN V...at least in the caddy race cars. Which I should clarify that I was referring to caddy race cars.

I meant C6. Thanks for the correction.I think you are talking about the C6 LS7. Regardless, a bad ass motor. If this article is to be believed GM has figured out a way to produce and warranty a 6.2 NA motor that makes +50 more than a Katech built LS7? No way.
2 of them.They snuck a 2.7 Ecoboost into it...didn't they @03cobra#694
its a GM mill...however that's not really the point...GM can make this kinda power out of a 6.2, but I don't believe that is the case at all here regarding these dyno numbers. I would chalk these numbers up to dyno shenanigans, or operator error....Though I do believe the factory LT2 mill is probably making a little bit more than advertised.
They also made 478whp in the lower gear, no 1:1 ratio. Also baselined a ram after and pulled realistic results.
GM engineering also said the car will defintitely make considerably more than SAE advertised power when cold.
Since you didnt read the article
Haha maybe some nawzI don't really buy the explanation written in the article, especially since this car made the same power pass after pass....MT is trying to sell some mother****ing magazines
maybe those fellas put a little gm hot cam in it and played with PE
Haha maybe some nawz
