I have no ax to grind other to help my Corvette community, so please don't post jack-wagon comments,

I have good friend at GM, yesterday I texted him I was placing my order this week for a ZR1, he told me about this new LPO Code RVK.

This code adds a new air inlet option, adds approx 17hp alone.

This option is not in the order guide yet, due to various reasons, but basically a paperwork issue. They are built and on the shelf, expectation is in a day or two to show up in the order guide.

When ordering ask your dealer to check the box off. If the dealer does not see the LPO code RVK in the order guide, then there is nothing he can do. Don't ask him to call GM it will do no good.

Your option then is to hold off ordering your car order or buy it from GM parts counter.

And no, once the order is picked up to build you can’t ask for it to be added.

I'm was also informed with this intake, the removal of the CAT's and using 100 Octane, the car will produce 830hp. I was not told the torque amount.
I was also informed no tuning would be required. I did ask where someone would acquire the cat-less down pipes, or brand P/N for this "off road" setup, my guy said he will ask and let me know as soon as he finds out.
I know several Corvette forum vendor's offer a cat-less down pipe, but I wanted to find out what GM used in their testing.

What I find most interesting is not the 830hp number itself, but the engineering in place for this much air flow change without a tune.

Poor-sha

Sounds like the GM performance air intake that was announced at SEMA.

Ridiculous that GM is going to sanction removal of CATS.

Not buying it, and it is not April 1st.

Legally they can not do that. Not unless it's sold as an "off-road only" car. IOW, you won't be able to put a plate on it and drive home.

He said "NO Jack Wagon comments". Jeez.

Sure. It's all about the tune, and the tune will just back timing off with lower grade fuel in. That's an easy one to solve for. It's the cat delete thing that's not passing the sniff test.

Literally.

Warp Factor

The OP never claimed that there was a cat delete option or recommendation from GM, only that they were able to get 830 hp out of it without the cats, plus the intake and 100 octane.

Guy's your killing me.

This info is not remotely saying removing the CAT's would be legal for street use, or the car would come equipped or optioned with cat-less down pipes. Nor will it come with 100 octane gas in the tank.

I thought that would be obvious that removing the cat's and filling up with 100 octane gas would be something you would do after you get the car.

It still doesn't make any sense for GM to spend the time, not to mention the money, testing in a configuration they know they will never sell. Someone would get a real *** chewing for the waste of resources.

Actually it does if GM is treating the ZR1 as a true track car. If you want to delete the cat's at home, add this intake, and buy 100 octane for your track only car, you can certainly do that.

I appreciate the fact that they're actually investigating this and by simple changes they've identified, we can add so much power to the car without the expense of a custom tune that could break other things.

Thanks for the info.
I can see adding the Intake option when ordering. That's a great move for GM.
Also, GM did a 100 tune for the Z06, I can see having the same type of 100 octane tune in the ZR1 as a stock tune. 91 Octane fuel you get 755hp and with the upgraded Intake and 100 octane fuel, 830 hp is definitely possible.

This car is going to be set on kill son, 830hp with only an intake (I'm assuming a cold air intake), pulling the cats off, & dumping some 100 octane fuel in her without throwing any codes or tune!? #Merica

Sometimes you just can't help people

A few other tid-bits that are not out in the wild much, if anyone knows additional info, we might add to this list,

ZR1 Blower Drive belt will be 11rib, vs. the Z06 8rib

Crank is about 11% stronger
If I recall the block, rods, pistons are the same but will confirm

Temp Validation testing target was for 100deg weather range

Front wheels are 19x10.5, 0.5 wider then the Z06, same tire, rears are the same.

Most of this info I got was back in November, I was asked not to spill the beans until after the Dubai Auto-show, by then I forgot to pass it on.
There is bunch more, cant recall it all now, getting old i guess.

oh, almost forgot the A8 in the Z06 was good and faster then using the M7, but after a few laps, over heating bla, bla. So the M7 as we all know was recommended for heavy tracking

For ZR1 the A8 is the recommended for the fastest at the track w/sustained use

I’m interested in if they are going back to the Titanium Rods and the Welded Tubing headers, like the LS9/ C6/ZR1 engine? Much lighter and more costly.

johnglenntwo

Done!

Shaved tires and this for the straights is fair ball competing with those "Stock" German car numbers over there. Whose Rules!?

Most importantly though is the fact that the chassis control systems are effective enough, and able to keep up! Demonstrate What!?

I need to call my dealer and have this option added to my ZR1 order.
