Try again.

The DI LS2 prototype, according to one of the engineers, produced "well north of 450hp". This was a 6.2L engine. The LS2 put out 66.7hp/liter. The LS3 69.4hp/liter. Assume the prototype made 475hp, 76.6hp/liter - or a 10% improvement, which is reasonable. GM increased power output 5% by going to the LS3 without variable tech or DI. Think a variable cam could add another than 5%? I think easily. But lets say just 5%. That means a 6.2L GenV makes 500hp. Could even be higher. In theory, a dry sump 6.2L GenV just made the LS7 obsolete - just as recent base Vette motors obsoleted the high-end Vette motor of the previous generation.

A 440hp "LS3 replacement" motor at that point could be about what.... 5.5 liters? And a 400hp "L98" replacmement could be about.... 4.9 liters? Ever heard either of those displacements around genV motors before?

Bad idea. The base engine is going to be more expensive than the LS3 it replaces. The tech to run 7000rpm would increase cost too much.

I think its just fine. But when you compare a Z06 to a Ferrari, the Ferrari usually rides a little nicer (so sayeth the big rags and places like Top Gear). Those Ferrari owners dont have much to brag about anymore .

With 330hp+ V6s in our future (LS1 territory) there is no reason to have a sub 400hp V8.

 

Well, I'd argue that's what people probably said about the the current LS3 Vette 6600 rpm redline on a pushrod engine 20 years back too. Remember when the LS1 came out, people were impressed at the 6200 rpm redline? Now look where we are now. As an armchair engineer/product dreamer, I refuse to default on the "that too expensive" response when it comes to moving current high end tech to the masses in the next major iteration.... if anything, its not as fun.

Anyways, that's why I'd say I'd be impressed if GM did figure out a way to make it cost effective for a base engine (for the Vette at least) with a 7k red line, cause it would be impressive.

EDIT: Extra points for anyone that can graphically map the redline of the pushrod engines used in the base Corvette over the years and generations.

That's an automatic - I'm only interested in a manual.

1 x 1 = 1.

 

you can manually pull the shift levers

 

Ya. I suppose.

 

Until someone is building a 330hp V6 that makes 375 lb-ft of peak torque, and sustains 300 lb-ft or more from 2000 rpm all the way to redline, it is not in "LS1 territory".

It's not the same and you know it.

 

Try what again? Like I said, 450 hp is a cakewalk. I wasn't saying it would actually only make 450 hp... That was just a number in reference to the weightower ratio that the article discussed.
