I've been checking with a number of vendor sites and had personal conversations with several of them regarding supercharging. What comes up during our discussions is exactly what else do you need to achieve > 500 HP (07 Coupe w/stock LS2) when installing a SC system. I was surprised to hear that many of them suggested installs on an otherwise stock motor. No headers, no changes in stock intake, no cam swaps etc. Perhaps it's more of a budget issue than HP. If you want an extra 50 HP then go with the other additions. Any thoughts/comments on this route versus, headers, CAI and change in exhaust would be appreciated.

 

Just for a fun car for the street, all you need is a supercharger installed by a reputable forum tuner who know's WTF they are doing. There are many on here that plenty of fellow vette junkies will be happy to chime in on with their recommendations( unless you are good with a wrench & are going to do it yourself). If you plan to go to the track as well & are looking for great 1/4 mile times, then there are other options like cam, headers, drag radials etc to consider.

 

500hp? Thats beyond easy. Buy a A&A or ECS basic kit, install it, tune it. Car will make 550rwhp all day long with a conservative tune with no other supporting modifications. Blower only....

 

If you just want some additonal pony's for more fun on the street, then add a 549bhp E-Force supercharger. If you are willing to pay to have the upgraded Z06 fuel pump installed(that comes with the 599 bhp kit) then you will have another sneaky 50 pony's under the hood. Car will behave like stock except when you give it the gas. If you ever decide to sell the car, and want to return the car to stock, the E-Force easy to remove to sell separately.

 

Car will behave like stock with a centri unit as well. Not to mention cost thousands less and have ALOT more room for expansion in the future if he wants it. I really dont get you pd blower guys, ive been down that road more then once and it ends up as nothing but a dark hole full of money if you ever want to make any real power. There great for sub 600rwhp applications, but start talking 600+ it takes some creative thinking and re-engineering.

My curiosity has the best of me right now though, whats the highest hp C6 with a edelbrock blower making these days?

 

500 RWHP is a joke to achieve these days. All you have to do is throw a AA or ECS kit on it and you are way over that mark with the most conservative tune. You don't need anything else to hit that mark. You can add headers, intake, CAI if you want but don't need it to get to 500 RWHP. Most likely with the AA or ECS kit you will be 550+. I'm going FI soon and after all the research I will be going with a ECS kit. After about 30 min reading about the Edlebrock and PD blowers I decided I did NOT want one.

 

I saw someone on here said one made around 750 RWHP with some tinkering. Too bad a simple pully swap can get you there with a centri kit (well you would want to beef up the rest of your car).

 

The OP didn't say anything about how to make maximum power, he said ~500 horsepower. Both a centi or a PD will easily get that without any other MODS. This tread is not about which supercharger can make the most power. I suggested the E-Force because it delivers excellent low RPM torque, which is nice on the street, and is easy to install(and remove later if he wants to). The OP said nothing about wanting a base for further expansion. Yes, he can choose between a centi, a PD or turbo's. I gave him my suggestion, you can give him yours. Just don't jump on me for suggesting a PD because you believe everyone is only interested in making maximum power. In my post I didn't say anything about a centi, much less run it down. Just the opposite of your post.

He can also get ~500 horsepower with a big cam, heads, headers, etc, but, in my opinion, they are much harder to remove[ie: expensive] if he wants to return the car to stock and IMHO, the car loses a lot of it's day to day driveability(and gas mileage) compared to a 500 Hp supercharger installation.

Ford offered a Centi in 1957 and Studebaker a few years later when they wanted a supercharged engine option. Back then the only PD was a huge GMC blower that stuck up above the roof of the car. Don't know if you were around then, but the GMC 6-71 blower was the supercharger of choice on the drag strip if you wanted to cross the lights first. Fast forward to 2009 and which supercharger did GM select for the ZR1 and later for the CTS-V. You must also think that GM must really have some dumb engineers, because they selected a PD supercharger for their highest performing STREET cars.

PS- I believe all the top fuel dragsters and the Funny cars are still running PD blowers on the drag strip(if you want to talk maximum horsepower).

PS- Late Model Racecraft took a ZR1 and changed the pulley(10.5 to 15 psi and a 93 octane tune) and got 750 rear wheel horsepower. Nothing wild.

PS-Lingenfelter took a ZR1 and put their improved snout on it along with a 2.6" pulley and 4" dia intake tube and got 740/740. It ran 9.813 at 145.74.

PS-A Miami Fl shop took a ZR1, added headers, a pulley change(10.5 to 18 psi) and a cam and got 705/689 and ran 10.55@137.

PS-Makes you wonder why Callaway and Lingerfelter runs a PD supercharger on their cars they offer for sale with a warranty.

The centi has different size head units, the maximum horsepower is with the largest units. The TVS2300 pumps 2.3L per revolution. I guess that if they wanted to make more horsepower they could add a 3.0L (TVS3000) just like centi does and go for more.

PS-Even my Mercedes has a PD factory blower. They were not trying to get the maximum horsepower, they were interested in providing a step up in performance while delivering 29 MPG on the highway, while keeping the car 100% reliable with a full factory warranty. I guess they could have chosen a centi and pocketed the savings(????), but they didn't.

 

With the centri kits you don't have to worry about a CAI since that part of the intake is replaced with the kit.

If you only want 500hp and like the stock exhaust there is no reason you can't keep it.

 

Would NHRA rules even allow them to run anything else?

 

If they were trying to slow then down, they might,

 

Like the centi kits, the E-Force kits also come with the CAI air filter. The various maggie TVS2300 PD kits come with the Callaway Honker and the LPE PD engines come with the LPE CAI.

 

The hardest part about what your asking for, would be detuning it to only 500rwhp. (every car leaves here in the 550 range stock or headers) Although I cap the power to 550ish for longevity either way unless requested to go higher or meth injection, headers allow the engine to have less back pressure, and basically let it make that power with less stress on it.

It really comes down to octane requirement, we have over 60 C6's on the road now, and about ten Camaros, that are over 700rwhp with a completely stock engine, headers, and meth injection for the fuel requirements. Many are raced regularly, and they are holding up just fine.

. . . hopefully one day I'll join forces.

 

Any of the kits on the market, centri or PD, will deliver 500-550rwhp with no other supporting mods. IMHO that IS the sweet spot to be at for a street car. PM me and I'll give a dozen reasons why...not interested in a b.s. debate on this forum. If it's cheaper you want, yes the centri option is cheaper.

As for the comment about a dark hole...total b.s. when done properly and it doesn't take much "creative thinking or re-engineering" to get there. Just a little common sense and mechanical ability worked well for me. Today marks one FULL YEAR that the Edelbrock has been on my car and it's been far from a dark hole and I've been over 600rwhp for a long time now....no regrets! Any of these kits have "room to grow". That is a lame arguement.

I don't know what the "highest hp" that has been achieved but a quick trip over to Camaro5 finds an LS3 based Edelbrock equipped 5th gen Camaro with the following dyno. How much do you "need to grow" beyond 732/738???

 

Ah shoot....Just mention a TVS and the centri boys get all up in arms. If the OP is undecided, he needs to take a ride in both. Easy decision after that. 500 wheel is easily done with any blower. 500 wheel is just a whole lot more fun when full boost is available at just over idle.

 

Your ignorance on the subject is amazing. So you've actually performed "just a simple pulley swap" on your centri kit and made 750rwhp? Or is the real story that you think you may have heard that story somewhere and the real deal is that you don't really even own a supercharger equipped car?

Holiday Inn Express syndrome

 

Do yourself a favor, take a ride to ECS and get the blower put on the car. I haven't met one person yet who has regretted it. If you research it, it's all about the tune, and it doesn't get much better than Doug's and the workmanship of the ECS crew.

 

Oh wow, where do I start....

Lets start with the comments regarding gm using the PD style blowers for factory applications. There is a VERY simple reason for this. They are reliable, require neary ZERO maintenance, and have great street manners. For a stock application, there is no other option. They are a perfect fit. If maximum power was there goal and not a 5/100k warranty, the car would have a centri or a turbo. There blower selection has nothing to do with what would be the most efficiant way of making horsepower. And i wont even get into a debate regarding lingenfelter and Callaway, ill probably get banned if I voice my opinon on that ****...

Also, did you really compare your edelbrock blower to the one on a Top fuel dragster? Really? Enough said....

AND..... Comment regarding the black hole of money and making power with a PD style blower... Have you ever made 800+rwhp using a PD style blower? I have.... And ill be shocked the day a edelbrock unit makes it that far because i truly dont see it happening. Ive had whipple, and kenne bell blowers in the past, making serious power with them is NOT an easy task at all. You are constantly fighting heat soaked IAT's no matter what you do. Ive built custom cooling systems, custom meth spray bars that flow directly in the runners, and basically redesigned everything that was originally in the "kit" other then the head units themselves. And even that isnt a true statement with the KB unit as I had to design and machine a custom inlet for it to flow enough CFM. So to say im just hating on pd blowers for the hell of it is nonsense. Ive been down the path and I will time after time share my experiences with people and make sure they know the facts before they buy a blower. This is why i stand by my statement that if you are happy with sub 600rwhp and never want to expand past that, go for it, buy a pd blower. You will be very happy with it. (although i would hold off for the whipple unit) BUT if you want to make the same power with zero effort and want the option for some serious expandability, go with a centri or turbo.

Now i know you mentioned a 700+rwhp camaro, a camaro is not a corvette. Alot more engine bay room, alot less heat. I have yet to hear of a single corvette making anywhere near that power level with that kit.

This is not about arguing about superchargers, its about making sure that the OP is informed of what he is in for if he goes that route. PD blowers are awesome for as street vehicle without high hp goals, they will nuke the tires at any rpm and are a blast to drive.

But if you want expandablity and more power from the get go for less money, go centri.

Thats really the bottom line.

 

Exhaust, Cam, 13psi with meth will get you there..... It WILL take alot more then that to get there with the PD blower on a stock LS2. Thats a FACT.

And with that, im out of this thread. If anyone has any questions or a would like to retort.... PM me, I wont turn this thread into ANOTHER poo flinging contest, we have all stated our opinions and facts, up to the op to decide what he wants.
