I'm not looking to supercharge my car for a while, but I'm wondering what SC is best for me, 2015 Z51 A8. I keep going back and forth in my mind between a roots and centrifugal. I'm not looking to make 1000hp. I'm more looking for 550-600hp to the wheels and run in the mid to high 10s. I've read the centrifugal SC make more power and at higher rpms. I've also read the roots style SC make great low to mid rpm power. I have looked up a few kits and the centrifugal SC seem to be about $2k cheaper as well compared to the roots style.
This car will be 99% of the time street driven (1500-2000 miles a year) and maybe taken to the 1/4 mile twice a year. So I'm definitely looking to keep the car streetable.
On the centrifugal side I like the ESC kit as well as the procharger kit.
As for the roots style I like the E force from edelbrock and I think I see a nice Maggie setup on its way?
I really would rather not run meth if possible. I'm just looking to do a SC with possibly headers and a tune.
I'm just looking for advice from you SC guys and vendors what kit sounds best for what I'm looking for?? Thanks.

 

There are valid points for choosing either a roots or centri. I personally have the centri and would recommend an ECS kit for you as well. With the base ECS kit you can meet your HP goals and have room to grow later if you choose. Also the centri is going to drive more like stock until you lay into it. If you plan on keeping your stock tires then I would also say Centri as the roots style blowers make more power down low and traction could be an issue. This topic has been covered in depth and Im sure you'd be happy going with either, but based on what you are shooting for- I would personally recommend an ECS kit.

 

I personally recommend an ECS kit. I have their kit installed at 7psi with headers and am making 586whp, right in your desired power area. And its incredibly easy to go from there, to 700whp and up with their kit. Was super easy to install and haven't had a single issue with it.

Centri systems are far better for these cars I find, especially for street driving, drag racing, highway passing. I could see a roots style doing better on the road course however.

I'd go with the prettiest kit.
It works as well as it looks.
The only one with a brand new SFI approved balancer included. (Interchangeable lower pulleys from 7.65" to 8.25")
The only one with a functional scoop to direct air through the intercooler.
A dedicated bracket to fit the 2015 rather than modifying or changing your water pump for an extra charge.
52 MM adjustable BOV.
All 5 ply silicone hoses with stainless constant tension clamps.
A&A high flow filter assembly (cleanable and reusable)
Top quality all the way.
Si or Ti Trim options (same price)

 

If you're sitting on the fence, the first 3 items Andy mentioned won my business. The machined balancer is high quality instead of bolting a pulley to the factory balancer.
Their air scoop feeds air from the highest pressure area of the car down to the lower pressure area.
Finally I did not want to buy a new 2014 style water pump to make the brackets fit.
An added note, the Si trim is more efficient in the 500-650hp range than any other centrifugal in the V8 engine range.

Not meaning to put anyone's product down. Just a consumer sharing his reasons for his choice.

Props to all tuners. There's not a bad set up on the market... Just different.

 

I was greatly considering the procharger over the other options. Anyone running a procharger care to share some feedback? I'm looking for the same #s as OP. I also appreciate the ease of install the procharger system offers. Andy at A&A, is your system easy to install as well? Why doesn't the procharger come with a BOV? Is it unnecessary for the procharger?

 

I have a Procharger with the vertical intercooler. Zero defects after one year, 6,000 miles and two races. Highly recommended. The OP lives in Long Island? ECS is next door. What are you waiting for? Tell your wife your vette needs servicing and drop your car off at ECS for a few days......

I like the A&A unit. I like the ram air intercooler and the local A&A dealer is a good tuner.

 

Thanks for all the advice guys. Seems like everyone is saying go centrifugal, any reason know one is saying to go with the E Force or Maggie?
I'm sure the centrifugal kits would give me more then what I'm looking for. I'm just wondering why Lingenfelter, Callaway, and the OEM use the root style- ZR1,ZL1,GT500,ZO6, CTS V, Hell Cat..ect.... Why do those respected performance shops and manufactures use the roots style?

 

The very same question I would like to know

 

Thanks a million.

ALSO: our bracket works with the 2014's and 2015's. So no need for swapping water pumps, etc.

We spent (3) full days renting a road course, and loading it down with datalogging, to make the best intercooler options possible. What we came up with was two killer units.

https://www.procharger.com/blog/proc...ce-and-testing

 

Ours does, three options actually.

- ProFlow High Flow Unit
- Bullet Valve (optional, looks like a "Tial")
- Race Valve (for those wanting something loud, and over 750HP)

 

The HellCat is a screw blower.
The rest still use the older tech "roots" style.

Simple answer is.....
- Ties to who makes the blowers to the OEMs using them ($$$)
- Patent reasons
- Bulk = cheap (making 5,000 vs. 50,000)

Roots give the "illusion" of really really fast, for the average buyer. Since "tire smoke" = fast. And if its one thing a roots blower is good at, is burnouts. However the modern motors make so much power N/A, they don't need any help in the burnout department, they need that top end power that pulls and keeeeeeps on pulllllllling.

 

We use the Eaton TVS Rotorpack as the basis for our patented GenThree Supercharger System, which is packed full of features like nobody else has or can deliver.

Here are some details of the new supercharger we developed for the Stingray, GM Trucks, and new Z06 Corvette.

Well I was hoping not to get into the comparison's between supercharger kits, but I guess I have too since we are the only company not throwing chips into the game here.

1, There is a reason why ECS kits are the most popular on this board IMHO, and why most of the top shops here use them. Follow the lead of the big name shops, they know what they are doing. Part of it is because we were first to production, but that only lasts so long.

2, Your ECS kit can come with an SFI balancer or without, any 10 rib kit comes with the balancer. However it's not needed we prefer not to charge you for it.
Unlike the C5/6, the C7 does not share the crank pulley with the supercharger so the stock balancer does not take anywhere near as much abuse as it did in the past. We have yet to have one fail, but if you would prefer an SFI balancer from the start we can certainly make that happen.

3, we use the strongest tensioner on the market which simply follows the lead of what the OEM manufacturer would do per TQ made, and our kit has the most pulley size options available while using the same belt, so you do not have to figure out belt sizing when changing pulleys.
We use a a separate bracket for the 2015 kit because of the size and strength of our tensioner, if we used a weak stock tensioner we would not need to machine the water pump housing to fit it. So that argument from the other side is really pointing out their own downfalls IMHO.

4, Our restrictor plate design offers the most low end TQ of any of the centrifugal kit options period. While also offering the greatest potential for upgrading HP without adding any financial cost to your supercharger kit pricing later. Basically with our base kit you can make 500 to 700 RWHP, (Vengeance Racing has broke 900 RWHP with adding a cam!) or anywhere in between without adding any further cost to the supercharger kit.

5, We include the Novi 1500 (T-trim) with our base kit, that equivalent is an option with either of the other two mentioned.

6, we include a high flow air filter.

7, we generally ship the kits without an air dam on the upper portion of the intercooler, and we have found no differences in IAT's when we did. However if you would like your kit to come with one just specify upon ordering. We make everything here so adding that instead of the lower air dam is the same price to us, so it's the same price to you. We just preferred to not take any cooling airflow away from the radiator since we did not see a gain in either direction.

8, We use real aluminum ducting, silicon hoses would be less expensive, but this is going on your Corvette, we looked for the best product not the least expensive option.

9, Your ECS kit can come with either the Tial Q, or the Tial QR blow off valve. QR being the quieter of the two. For those looking to have virtually zero BOV noise we can add a second QR valve to the system either at the time of ordering, or afterwards no problem.

10, This one is very important, I have tuned every type of supercharger kit there is for the C7 and the ECS kit has the smoothest MAF readings of any of them hands down, even without a MAF screen. What does that mean to the end user? At low throttle cruising you will not feel any surging in the car as you drive. To me drive ability is everything, especially in a brand new car.

11, Our brackets are very rigid, no long distance spacers that give flex to the head unit. Try pulling on some other styles and see for yourself how much it can flex, or break as I have seen happen to the same car twice!

12, Our intercooler is a very high flowing, large cooler. We have ran that core into the mid 8's in the 1/4 mile and is as large as any other out there. I think all the intercoolers out there are actually well made so no real gain from one to the others kits.


Black is by far our most common sale, but we can ship them polished, or a mix between the two. Black brackets, polished spacers, whatever you choose.

Here is a link to "the top 5 tuner packages for your C7" where the ECS kit is listed in the top 5;
http://www.0-60mag.com/news/2014/02/...uner-packages/

Look for the TV show "All girls Garage" on the Velocity channel, where they installed an ECS kit on their show. Or just look at the many high HP builds going on daily here on CF from the big name shops. Possibly more importantly, look how many 550-700 RWHP builds there are here with just a couple of mods, our supercharger kit has that down pat, you really do get the best bang for the buck with ECS, hands down!

If anyone has any questions feel free to ask away! Thanks for your interest in ECS products, we greatly appreciate your business.

 

A&A kit all the way that's what i have ....

 

I have owned 4 supercharged vehicles. Two centri's on a C6 and a C7 and two roots style. The roots style by far is the closest thing to Oem. It looks like it came right from GM. They are also very quiet and linear on power. My first roots charger I put 130k miles on before I sold it and the only maintaince I performed was one oil change. For a mild build like you are wanting any option will get you there easily. If you want to up the power in the future (which you probably will because its addictive) then a centri will get there easier. I love my centri on my C7 because its the opposite of a roots. Loud straight cut gears, blow off valve and a top end surge of power.

 

Well said my friend

 

Thanks for all the info guys. At this point in time I'm leaning towards going with the Edelbrock E Force. It puts me in the power range I'm looking for and comes with a tune. It looks to be a few grand more then the centrifugal kits. If I was looking for the highest hp numbers I'd definitely go centrifugal. The thing I like most is it includes a 3 year 36000 mile per train warrenty(upto $16500) being a SC will void the factory warrenty.

 

Being that you are on the island, if you need install help see the guys at JTM in Deer Park. Good luck with your build.
