Impressive technology. Welcome back LT1!

What? No Opti?

My gen 2 lt1 doesn't run a opti

Vented opti on my 95 has been issue free. Direct injection and cylinder shutoff capability is the future. Hope the new LT1 will bolt in to our chassis. Maybe upgrade mine at 300K.

Im pretty surprised to see the cyl deactivation crap migrate over to the Vette. Its not overly reliable and it really limits anything more than mild aftermarket cam swaps because of the lifters. Probably just means a conventional lifter swap and away ya go with whatever cam ya want but first the new E92 ECM needs to be cracked so we can tune them which likely wont be much fun for the first few years or so im sure...

Ever tightening new fuel efficiency standards will likely mean a harder task for the aftermarket to modify OEM designs. In fact, despite marketing claims not all modifications are true performance enhancing. GM has a conservative estimate on the real torque and HP numbers released.
Sometimes it's best to leave certain stock items alone.

And i JUST got an LS motor!

I don't get the comment that says they are the first to use direct injection on an overhead valve engine. Do they mean pushrod engine?

LS is still the way to go for a while yet imo. Heck we're still making them things better and better

You can probably buy 3 600 horsepower BBCs for one of those..lol

They will likely hack the pcm before the injector companies step up with something to use. That is the hold up with the 6cyl in the 5th gens once they are out of injector they have no options.

Agreed the injectors capabilities and learning how to tune them will be the first big hurdles to deal with. DI is really the only truly "new" technology to the Vette. We've all had the other stuff to play with for a few years now in trucks and camaros.

Once these engines hit the new trucks and Camaro the mod craze will be in full swing. Hope they prove as tough as the LS

OHV utilizes pushrods, so yes, that is exactly what theyre saying.

I dunno but I thought diesels like the 6.5 were considered direct injection

or a 1000 hp shitty old 400 sbc with hairdriers.


as for cyls cutting out, how come every single person i know with a hemi or chev that cuts cyls doesn't see any fuel mileage difference from the same truck they had before with same engine without cyl cutout? huh huh ....huh
