2019 ZR1

I'm going crazy trying to decide if I should. I'm glad that Matt did the thread about people not having trouble with their Z06. I'm thinking Edelbrock because they offer a warranty. I would use their tune that comes with it so if I have any problems they would have to cover it. I had a Edelbrock on my 2011 SS and didn't have any problems. My buddy in a Chevy tech and says that he can put it on for me. I guess it has to be put on at a authorized dealer. He would do it at his house and if anything goes wrong he we would say it was done at the Chevy dealer because they are a authorized Edelbrock dealer. What would you guys do.

If you do that and pay for the warranty then you shouldn't have anything to worry about until the warranty is up.

If its covered under warranty its a no brainer.

This is something I had considered and from what I have learned about the LS7 , is that it is a high compression motor and does not respond well to supercharging. This is why GM used the 6.2 liter LS9 for the S/C ZR1. It is also why many here have gone to cam/header/intake..etc type mods. Now there are still some that do, but I don't think they can run much over 5 lbs of boost and also do bottom end work to respond better to more boost. I am hoping someone else will chime in on this thread that has a boosted LS 7 and can confirm or deny this. Hope this helps.

I really thought I would get more responses. 119 people viewed this but only 3 comments. I really do need some help here. I'm in Daytona Beach Florida until Sunday and when I get back home to Pittsburgh I want to be able to make a decision what to do.

I ran 6psi on an A&A kit, made 705rwhp. They are fine at that level. Keep a blown ls7 to the 720rwhp range or less and it will be happy. Doesn't take much boost to get there. LS3 are stronger and can take up to 800rwhp but the ls7 isn't weak when adding a blower.

The only issue I see is you will want to turn it up, then the warranty will be gone. They are too much fun with big power. 600rwhp will get boring quick, then 700 and so on.

What other mods did you have to get you to 705RWHP???

I wouldn't own a z06 without a blower lol. Ysi on 6lb here

I don't know much about this stuff, so people please chime in if I'm wrong: the Edelbrock warranty on your drivetrain holds only so long as you haven't done anything that would otherwise void your drivetrain warranty, and only so long as you use their Eforce stock tune and boost, which yields 657 hp at the crank. You can do the math for how much that translates to the RWHP.

If you increase the boost, change the tune, or mod your engine in some other way, then - if I recall correctly - you will have voided the Edelbrock warranty on your drivetrain/engine.

People have argued that the modest power gains (657 hp at the crank) are a poor value for the money spent on the install. But if you're looking to keep the drivetrain warranty on your Z06, you don't have too many options for performance/HP mods.

First big question YOU need to answer is, What are you using the car for? Most people can't drive the car to it's fullest potential with stock power, let alone adding another boosted 100 plus H.P. Then you must think about the warranty. Many "modders" understand that HP isn't cheap, and with HP there's no such thing as a warranty.

Understand also that people are blowing there ls7's with zero mods.. now you're going to force air into an already thin piston sleeve. You had better look into getting the heads reworked. I just don't buy into these "warranties" sorry.

If you are going to track, I wouldn't blow the car. If not and you just want a beast... I'd go with A&A kit. It looks amazing, sounds bad ***, and you can get a ton of hp if you want to grow with it.

Can't the piston sleeves be worked or re-sleeved to better protect the engine?

Interesting how GM went from LS3 which held better boost to an LS7 that didn't hold as much. Was it because the LS3 is lower compression when compared to the LS7?

Whatever you do, ask yourself what the "end state" will be before you have Frankenstein tear it up.

600 rwhp, 700 rwhp, 800+ etc.

What options do you have to get there safely?

If 600-650 is a modest goal, perhaps Heads, Cam, headers, etc will be the ticket.

If you are striving for "more" you may be limited to forced induction. Then, what route do you take?

Heck, 'tis the season to be jolly.....what's another $20,000 on a $70,000 2013 Z06?

Go for broke. You only live once.

Good luck and keep us posted with your selection. I myself was inquiring into the Procharger F1-R a few weeks back.

I have a lot of friends with a lot of modified ZO6's and other C6's. A good friend of mine is Brian Reckart and he is the go-to shop around here for late model Corvettes. I get to see a lot of the builds done at his shop and pick his brain on how they turned out. It doesn't make me an expert, but it does make me opinionated.

1. I would do an NA build on an LS7 rather than a blower. Bunch of heads/cam and supporting mod ZO6's running around here and the owners are enjoying the heck out of them.

2. If you do insist on a blower, do an A&A kit. The Edelbrock is a big heat pump. IAT's, coolant temps, and oil temps are all too high after a pull or two with the Edelbrock kits. I have dyno'd and data logged both of my ZR1's and they cope amazingly well compared to the aftermarket Edelbrock kits.

3. If you do an A&A kit, like others pointed out, keep the boost low. Like 5-6 pounds, if you want that stock LS7 to live.

4. If you want to be a dream crusher, street terror, high roller, etc. pull the LS7 and have it built. Then go twin turbo or YSI and enjoy over 1000 to the wheels... but build the motor first. This option will require a fat wallet.

I love owning a car that has way more power than I need on public roads, its fun when the opportunity arises

Procharged here and I love it!

705rwhp was blower, headers and a mild cam.

GM never supercharged an ls3. The only SC motors are LSA and LS9 which have different pistons/heads/rods/crank/etc.

A mild 600-650rwhp will drive so much better than a 550+rwhp n/a car and get better gas mileage.

2019 ZR1

I won't be tracking my car. I just want something that is going to kick *** stop light to stop light. The only reason I was thinking Edelbrock is because of the warranty. I will just use the tune that comes with it so I would be able to keep the warranty. For what I'm going to do with my Z I think 657HP is plenty. Well I said that about my 2011 Camaro SS also and I kept building it to 647RWHP. Lol

LPE did ours. two whipples and a one chrome Maggie. you may want to give a Jeff a call. also with their deal they have a 36 month or 36000 mile warranty. the cars are a blast drive.

I have a carbon hood and for what I paid for it I don't want to change it..

Put your mod money toward the cost of trading your Z for a ZR1.

You'll end up with a hell of a lot more then just a blown LS7...
- CC brakes
- DD clutch
- Forged engine with piston squirters
- HD cooling
- HD rear end
- HD torque tube
- 5/100 powertrain warranty

I'm probably forgetting some things but you get the idea.

2019 ZR1

I thought of that but I'm not going to lose my *** trading or selling my Z06. The way I look at it is my Z06 had a sticker of $98,000. I paid around $83,000 after all discounts and my GM card $3000 discount. I can put a supercharger on and exhaust and get a 5 year 60,000 mile warranty for $11,000. I should of listened to my son when buying my Z06 because he said to get the ZR1..

You might want to tell Callaway that. SC652
