I have a 2010 corvette GS convertable with the 435 hp engine and the electronic device to open the exhaust. I am considering adding the edelbrock 1575 kit and boosting the horsepower to 600hp. Has anyone used this kit as its a $ 10,000 upgrade and how was the performance. Also on this corvette I went for the paddle shift, its hands down better than the the standard transmission.....thanks for your comments

They say this is the real deal but it offers no auxiliary injectors in their package. That seems like it will limit power to 550-ish and still not have enough fuel to support the engine down low because the pump won't keep up. It looks great for sure but needs help to actually work - FACT

Thank "i10fwy" for the above picture and all the rest of you who have provided thoughtful analysis and recommendations on this thread. It is good to have really knowledgeable engine folks like you on the forum. Based on what you see, what are your thoughts about GM putting the supposed LT4 supercharged motor (below) in the upcoming Z06, i.e., will it fit under the hood, could it make 600 HP, and anything else you might conjecture with the rest of us. Or, are any of you hearing the Z's motor might be twin-turbo'd? Thanks again!

I can't see a twin turbo package at this time. 1. Vette guys wont go for a TT V6 package and 2. The TT V8 will not package as well as the ZR1 style TVS2300. The TVS has proven 800 is possible and that is about the limit for legal reasons and cost. Vette guys as a whole are nt goig to purchase $150k cars. I nean I would but historically that has not been the vette guy.
So plan on 550 N/A motors and 700 supercharged - IMO

do know what the Injector duty cycle was on the header and cam stingray that put down 502wHP?
when GM does the Z07 or ZR1 (which ever one they call the supercharged one) do you think it will still be direct injected? If so good chance those injectors will work on this car right?
The low side fuel pressure does not change on an NA application. The stock injectors and high side/low side fuel pumps can cover the heads and cam change.
I am sure it will be direct injection based on the success of the Cadillac turbo cars. lets talk about a centrifugal blower vs. the roots hybrid design. The centrifugal has low boost down low and therefore requires less fuel down low in the RPMs. However the TVS2300 design has full boost down lower and that presents a problem for the stock pump and injector combo.
The pump is camshaft driven so at half engine RPM it has basically half the volume to keep up. So when the TVS goes full boost at say 2800 RPM the pump most likely can't keep up.
Just an observation.
We did a turbo kit for a v6 DI Camaro and it required a 2nd set of injectors to cover the boost down lower
Thanks..
Next year or over the winter im going to start upgrading. Trying to learn as much as possible.
Going be the big do I go Screw, Roots, Centrifugal, or Turbo lol..
Was curious how far fuel system would go. I didnt know was cam driven..
I have driven cars with them and lets just say it makes it a completely different car, but Magnuson has a similar unit called the Heartbeat, fits under the hood, saw one and went for a ride in a 12 G/S and it seemed stronger.
Your thinking of the Maggie TVS2300, that one required a different hood, they have a new 2300 called the Heartbeat, fits under the hood and overcomes all the Edelbrock's shortcomings. It makes like 25 hp and 45tq more than the old style Maggie. Seat of the pants dyno said it pulled harder than the edlebrock.
In truth it looks like the stock fuel system and inj package can support 650-ish but that is at WOT + max RPM. At say 2500 RPM and 5psi the stock fuel system will already fall short or be on the ragged edge. Its all too new. I could be way off but that is what I am hearing. I see 3 new companies have twin turbo kits out for the C7. Granatelli, Lashway and STS but no one has address the fuel needed and we put our kit on hold while we tool a manifold to add extra injectors per cylinder. Based on the success of our C5, C5, Gen 3, Gen 4 and Gen 5 Camaro turbo kits we see full boost at 2000 and that is a recipe for disaster. We will not ship a kit until we know it is dead safe. That’s the problem with turbo kits…we ship it and say leave it at 7psi and the customer says oh ya I promise I won’t turn it up
. Then they try 10 psi “but only for a second – ya right” and when it blows up…its our faultA centrifugal set for 8psi at 6500rpm will only have say 2 or 3 by 3500 rpm and that means they require less fuel (because they make less power) down low.
Roots and Screw blowers are basically the same thing
i gotta agree
