2012 Grand sport, M6. LS7 exhaust to Corsa. No other mods.
I already have a cam picked out from Pat G, and was going to do GenX 255 heads. So I would be looking at around 470-500rwhp. With an ECS blower I would guess 550rwhp. I used to race a lot and built my own LSX cars, but this will be a street car. Possibly run Beech Bend once to get a trap speed. I drove about 6k miles last year, but a road trip is not out of the question.
Basically, I am only unsure of the supercharger because it's an unknown to me. I have always been NA. I want something that is tame around town or cruising, but offers added power. The cam Pat chose for me is small, 220's intake at .050, so even though it will have some lope, it is perfectly streetable.
So, someone with experience talk me into or out of the supercharger. Is it going to be a maintenance nightmare?
I do not want the added headache of a meth install, but am willing to go with the stage 1 fuel system.
Thanks for any advice.

If you want something that is tame around town, go with the ECS kit. You can make anywhere from 550-700+ rwhp easily. Very little maintenance for supercharger, if self-contained, change oil once per year. Meth is very little maintenance too and is a great addition for safety on boosted vettes. Can still do a mild cam with blower, or not.

I was also hesitant to add meth. But I bit the bullet and did it. I made 40+ rwhp (~63* ambient in dyno area) on a Mustang Dyno without being meth dependent. The install looks stock. If you didn't know what you were looking for, you'd never notice it was there. The electronics are all hidden behind the Bose amp or in the glove box.

I drove the car for over a year without meth. Time will tell if the extra 40 rwhp is worth it.

I've had both and would go with the blower kit. They usually put down 550rwhp with no other mods. If that's not enough all you have to do is pulley down and add a meth kit. Blower + meth + headers can get around 700 to the wheels.

.gearhead.

Supercharge it.

Get the blower

I originally had just a blower but always wanted a thumper cam. So I now have both.

ECS all day. Drives 100% stock when cruising around. I would get in and do a 1200 mile trip in it tomorrow and not think twice. When you are ready to put the power down, just mash the pedal.

Blowerrrrrrrrrr

A&A here.finishing up my install.I said to my self go big or go home.seen too many guys here start with a small head unit keep in for a year or two end up upgrading down the road.

Having had both, I would do the blower. I make nearly 200 more HP with the blower on a bone stock valve covers never removed ls2 with a blower then I did with heads and a G5X2 cam in a built 347. Yes, that setup is now weak, but it was cool back then.

ECS supercharger, hands down-no questions asked-no substitutes, and no I'm not biased in the least!

Seriously though, I think you would fit into a supercharger better for what you described above. Feel free to contact me for a great price, and one year interest free financing is available too.

ECS or A&A. I did A&A base kit on a stock 13 GS with just LS7 exhaust manifolds and made 600RWHP. Car was a blast and very reliable. Drove it on several road trips (including from Dallas to Tail of the Dragon) without ever worrying about it. Car drives like stock when your not on it. For street use, you don't even need meth (on the A&A) at least, but I'd probably go ahead and do an Alky kit and run 50/50 meth/water for safety. I have the blower oil and belt changed once a year, that's the only extra maintenance.

Looks like you all have convinced me. Doug@ecs. I will call you later this week.

I'll play devil's advocate and say heads and cam for your goals. From what you say, it doesn't appear that you are shooting for big numbers. I enjoy the experience of a big cam ie sound/ smell/ rumble. Run a set of drag radials and she will hook and book.

Also, get some long tube it really makes the car scream.

If your shooting for big 600+ then supercharger all the way.

Heads, cam and LTs are going to cost almost as much as a blower, and require a little more maintenance (spring changes every xx thousand miles). If you're only looking for mid to upper 400s RW, then cam and LTs would work and cost less, but again a little more maintenance than a blower. If you like the "cam" sound/smell, then it's the only way to go, but that didn't sound like what OP wanted.

Realized I missed your statements on meth/fuel earlier. A&A kit will not need anything more than the included boost-a-pump for 600RWHP. As I mentioned earlier, the A&A can run just fine without meth. I did it for a full year in Texas with a hot summer and no issues. Yes, you'll loose a little power on repeated pulls, but it cools down quickly with their intercooler design. ECS should behave pretty much the same, although there is some argument on intercooler efficiency versus A&A. (They are both great kits.)

DOUG @ ECS

For those who have not been on the forum that long, RPM in CA, (who used to be the tuner for Andy) did a back to back test of the two intercoolers on his own for a customer who requested it and posted it here.

They came up with identical IAT's on that build which was stock with headers, but for bigger power builds ours flowed more. Just looking at the two designs it seems obvious to me, but this test was done across the country by an independent shop that concurred.


Just an FYI, thanks for your recommendation.

neverstop

blower all day. I've worked with both shops and they are both A+ top notch 10/10 guys and both kits have been proven to make huge power. I have made 907whp through ECS intercooler and have a friend who made 850whp on a different setup through stock A&A so I think they both flow well enough for those power levels.

I'd say do the meth because the extra octane and lower IATs are awesome and it's really not a hassle.

If you had a LS7 I would say heads/cam and stay NA but since you have a boost friendly motor BOOST IT AND ENJOY!!!!

Yeah, I know that tuner and once met him around 2005 or so.

That fat tuner promised to send me a tune for my upgraded setup.

Well, bored of waiting (it's now 10 years since the request) and I've been tuning by myself for many years since then. But that's another story.

Just wonder what revision of the intercoolers was that.

Anyway, it is true that any Corvette has a limited space for a big intercooler(s).
