Decided to convert my lease on my daily driver so that I will have it for much longer. I have a base 1lt C7 Stingray. She drives amazing and get many heads a turning no matter where I go. My push to go to a C8 isn't near as much as it used to be.

I do however want some additional power. Little more under the hood. Have seem many cool options. Not huge car guy, love my car, but I don't know that much. I need some help.

  • Have a 8K-12K Budget (Maybe more, for the right situation)
  • Don't want cams
  • Want 640+ HP
  • Heard positive things about Procharger, ECS and Magnuson Superchargers
  • Live in Las Vegas, so cooling is important
  • Don't want to change my hood (racing stripes)

Any opinions out there on solutions?
Any opinions out there on shops on the west coast?

Welcome to our forum txtdawgs (and fellow Las Vegan :cool: ). As a start re your need for power, put the word supercharger in our Search Community, and you will see a number of related posts Search results for query: supercharger. Is your C7 image from Valley of Fire or Red Rock?

It is from Red Rock. I took "Safire" out there the weekend I got her April 2019 for some pictures.

Wonder if you can just do a super charger install without the headers and all that junk? I know it would have to be tuned. But even a gain of 75hp would be fine with me.

Generally when you start getting over 600hp on LT1, you get into meth/alky, headers, piston change etc and more stress on the engine.

Those of us with bolt-on Superchargers pick up about additional 125hp are running 540-555 rwhp and 535-550rwtq and about 620-640 at the crank.

These numbers just for comparison or benchmark, the average C7 Z06 dynos at around 545-555rwhp however some of the big performance shops Vengeance and WeaponX have seen some stock Z06's dyno at 572 and 585 but they seem to be the exception and thus higher than the average.

That said, I don't know how you plan to drive the car but 640hp is alot and not sure how the road manners will be but my 550ish is plenty for whoever pulls next to me be Mustang 5.0, Mopar Gang Squad or even big brother Z06 all are surprised that who they thought they would pick on wasn't so little. LOL :)

Lastly, drive-ability was a key point in making my decision on how much power as under normal driving conditions you would not know the power that it has in normal city driving or long distance cruising it drives OEM. It is only when you mash the gas pedal do you learn that there is more there when you needed it. :)

PS: You mentioned the popular names IE: Procharger, ECS and Magnuson Superchargers but you left out one which is what I have A&A Corvette Supercharger which has a strong track record as well and It is the only centrifugal supercharger designed specifically for the Corvette. I also like because my engine bay remains looking stock.

I also have an A&A supercharger and am more than pleased with the performance and reliability. It is the only centrifugal supercharger designed specifically for the Corvette and it has some heavier duty components than a ProCharger or Vortech. Mine dynoed at 535 RWHP (about 640 at the crank) running a conservative 7 PSI.

I would go with procharger and if possible, headers. You will need to modify suspension to Z51 stabalizer and shocks for wheel hop. You will need a tuner...extra 750 on initial tune...must register. It will be hard to hook up that power so be prepared for different rubber. Obviously reliable installer. Promaster could recommend in Vegas.
I have headers, cold air and tune and has around 520 at the crank. about max power to hook up with factory tires...still got to be awake. I upgraded my 2LT to Z51 bar and shocks. Quick.

Be very careful. The Stingray was not built to have 640 HP. Not the right suspension, breaks, etc. Those would also need to be upgraded.

I would have disagree, I have a 2014 stingray nor a Z51, and have a Supercharger, meth, header, exhaust, with a mild tune I’m at around 625 RWHP. I have had zero problems so far. I will say I do not run my car very hard. Just when there’s a need for speed and an open country road.

Disagree all you want. Not sayng there will or won't be issues, just to be aware. The non-Z06 chassis, suspension, brakes, etc was not engineered to handle that power. Why do you think the Z06 has much bigger brakes, stiffer suspension?

Well one reason the Z06 has bigger brakes, sup, etc. cause it was designed to take to track.
if your tune is correct you should be fine.
yes if you run the blank out of your car. Then yes car won’t hold up.

Just copied from another thread I was a part of. This was Andy of A&A Corvette Superchargers responding to questions and speaking. Just posting as FYI

At 625 on LT1 without the pistons it will be JUST time when it will blow a piston on this stock set up. For no more than the cost of it I wouldn't run the car without the meth.

"The standard kit will safely be between 575 - 600 RWHP on 93 Octane and conservative tune but that you can't get there on 91 Octane. The system is capable of much more BUT you are limited by the octane of the fuel".

"At 91 Octane, you will get about 560 on a stick and 540 on an auto. With Octane Booster, the kit will safely make 600 but it is LIMITED by the Octane. You just need to be more conservative than a C5 or C6.

"Your 2014 A6 Z51 should get about 580 on the A6 Automatic" "We don't use catch cans because with proper ventilation we see no need and that's why we use the 5/8" vent line".

"Below 600, these engines are fine without Meth/Alky or without Pistons/Rings.... It's when you start to go over 600 then you need to do other mods or you run into problems"

I'm assuming when Andy says "below 600" he is talking about RWHP.
Interesting info about the catch can. I have noticed that since adding the supercharger my catch can collects less fluid and it is not as "gunky". As a side note, my installer also deleted the AFM so I'm now running 8 cylinders all the time.

I think that is a reasonable assumption about the RWHP because at the crank is around 640.

The bottom line I think what’s being said is things will Might be fine now but over time the pistons/rings can't sustain.

So, either get caught off guard later at some point in time or doing the proactive mods at some point before you are forced to is what I read into it.

I will say that if you read enough threads, the consistent message is the LT1 is great and can handle 600 safely but the odds go down as the power goes up.

I agree the more we do to these cats more you could have a problem. It’s the game you play.
My big problem is getting tires to hook. I still run stock tires. Any ideas
