600 hp or near it is a lot to me, especially in something light for a street car. Guess it's all relative to the circles you hang out in. More than a few TT Gallardos and Ford GT owners who think anything below 1200 hp is not a big deal. If you have to baby it through the first three gears and part of 4th, it's probably a lot of power.

 

Agreed.

With the Shelby GT500 @ 600HP+ completely stock, I think it sets the bar high when going FI in a C7.

Its hard not compare, even if the GT500 weighs more.

 

The issue with the Eforce on the C6 was the limited intake runners inside the manifold part of the unit. It limited airflow and low 600's rwhp was about the limit. Unless there is more hood clearance allowing a taller manifold with more runner volume, 750rwhp isn't going to happen on a stock displacement engine with an eforce.

Camaros and mustangs allow for longer runners and more cross section from there being a ton of clearance to the hood.

 

A centri will easily hit 750rw

 

Interested in this kit due to the fact that they offer a powertrain warranty.

Waiting for pricing and dyno sheets!

 

Spin, you are the man...

But what are you basing this off of? You believe the stock fuel system is capable of supporting that level of power? I hope you are right, that with meth injection will get people by for a while if that is indeed the case.

 

I hope more than that. That's what you get on a c5 with a centri..

 

not really especially when you have mustangs with 662. Sure maybe 10 years ago but hell most FI 4cy guys when they upgrade hit that. It's not that much anymore and will probably get your *** handed out to you when you actually do race something with some grunt.

 

I will agree that in todays world.... 600 or 700 rwhp is not crazy, and on the internet, you are nobody if you don't have 1000.

The reality is, where I live, and in most places, you cannot use these power levels anywhere. I personally can never run my car full out for more than a few seconds. In 10 seconds you are at 130 mph. If you happen to get caught driving like that here, and the cop is having a bad day, he can take your liscence and your car right on the spot. Sadly they have taken the fun out of it.

I think 600-700 rwhp is a great number, that can be achieved very reliably, and makes an extremely enjoyable daily driver. 1000 is great for bragging rights, and the odd highway burst, but to make that kind of power reliably is not cheap, and not easy.

 

 

I was stating the C7 will as a platform, make that power on a 6.2L. I wasnt saying it didnt need fuel system upgrades. The C7 uses a high pressure system unlike the 3 bar C6 fuel system. The most successful builds will use a parallel fuel pump and bigger injectors. Using direct injectors on old genII chevy motor has hit over 2000hp on my crew's builds such as Shawn Fink's car below. Its a big increase in power if its set up right but the high rail pressure opens the door to new problems for guys that just think its as easy as a few home brew fuel lines put together in a slap.

I will have the new Z06 when its available and will disassemble the engine after the first week. I can't talk about it much until I do and I'm not one to just recycle bad internet info. What I learn will be available to everyone for free, including cam results right out the gate.

This is Shawn's street legal Nova wagon that he drives 1200 miles on the hiway and back to drag week---puling a trailer! Keep in mind this is the old gen 2 platform and not much more displacement than the new LT1. direct injection is a key player in the power it makes.

 

People in this thread are talking about so many different topics that some aren't commenting on the same things. People who are quoting 570 are talking about the eforce which makes about 550rw on the stock 6.2L. Big mods don't get much out of it. Big strokers have gotten 700rwhp with it but then you can hit 680rw with a 441 stroker N/A.

The E-force will not do much better than 600rwhp on the new 6.2 liter because its intake manifold under the unit is integral and has limited space causing airflow issues. It will do a bit better though because of more efficiency. The centri s/c's will make more power than the C6 because of upgrades across the board making it more efficient with no airflow limitations. The stock pistons will again be the limiting factor. I've been assembling lower ends with no failures so I will just get rid of the stock rods and pistons as soon as I get the car. I am of course assuming the Z06 will have a big motor and not just a forged 6.2L. I can add turbos to the base car myself.

As always I will post lots of info/pics/cam specs for the DIY guys.

 

Thats the sad part. Insurance nightmares will abound if you get an exhibition of speed summons. It will more than double your insurance rates or worse. It will be about pride of ownership in the end.

 

I think people get too wound up in the power numbers and forget what that does to the rest of the car's dynamics. If all you want is to go fast in a straight line you can pile on the power forever to go faster and faster. I feel like the older generations equate the 1/4 mile as the be all end all performance metric. The quarter is fun and I had a high 9's Toyota Supra that was a hoot to drive but was miserable any time i got in the twisties due to how absolutely focused I had to be on how much throttle I gave it any time I came out of a corner...then there was driving in the rain, after hydroplaning into oncoming traffic and being a lucky as hell **** missing everyone in my butt clenching spin due to changing lanes and spinning a tire on the painted line, I decided to tone it down. That's about the time i started doing track days and eventually AutoX. Being quick on a quarter takes skill, theres no doubt in my mind there, but the skill required to go fast on a track requires much more focus and a well balanced car. Too much power and you lose time due to spinning tires and fishtailing out of turns, too little and you lose out on the straights.

I think 550whp in the C7 will be absolutely perfect for the car as it's not so much that the suspension and chassis will be overwhelmed, 305 meats in the rear should be more than capable of handling that power in R-comps, and for daily driving it shouldn't require that nagging back of the brain warning that the gas pedal will kill you if you don't respect it at all times.

People will always want to go faster in a straight line, but if my crotch rockets have taught me anything, fast through turns is much more fun than fast on straights.

 

Just my $.02 on power of daily driven Corvette. Just as in the case with the C5 platform with GEN 3 engine the GEN 5 LT1 will evolve to make even greater numbers once the aftermarket develops solutions to bottlenecks in fueling. SpinMonster's comments are right on target regarding performance potential of the improved technologies of the DI 6.2's, it's just a matter of time.

I own a supercharged C5 putting 708/640 to the wheels and for a street driven car it is plenty for me. Granted I do not track the car and I'm not looking for higher dyno numbers and if I were to be modding a C7 I would put drivability and reliability first before big dyno numbers. I've ridden in a friends ZR1 and IMHO it's a well refined car with smooth power delivery and plenty of it for the street. I agree with the points made by realcanuk and Supermassive regarding street driving and the C7 platform. It's all about the driving experience and the ability to get in my car any day and enjoy the total experience of handling, comfort, power and above all reliability. Again, just my $.02
