A&A vs roots?
Looking to see if someone can give me insight on the drivability and reliability for an A&A or procharger kit vs something like a TVS kit for a base model stingray. I really want to boost my C7 I just don’t want the car to become a pain in the a$$ mechanically when I drive it. Also if anyone can chime in on the difficulty for installing a roots vs centrifugal kit and maybe what some of you paid to have a kit installed? Thanks for the help

Interested as well. From the various threads I’ve read on this forum, roots style (Edelbrock, Magnusson, LT4 conversion) seems to best for street use where you’ll have the most fun since you get immediate torque, however they are difficult to launch and may have heatsoak issues. Centrifugal superchargers (A&A, Procharger, ECS) kick in at a higher RPM (>3000?) so they are easier to launch and make more top end power which makes them ideal at the drag strip or highway pulls. Would love to hear feedback from owners though.
I’ve read installs for either run about $1500 and a good tune is around $600.
I’m leaning towards the A&A kit myself. I love how integrated the roots style units are and the immediate torque sounds fun however I feel for my usage the centrifugal blowers would be a better fit. I’m already struggling with traction when launching with the stock LT1 and I love the whooshing sound which you can control when picking out your BOV.

This answer will entirely depend on the end goal of the vehicle as well as everyone's perception of streetable. For a street car and sheer fun factor, the PD blowers are very tough to beat, they make instant tire frying torque and the power is there everywhere, even the very large Whipples and Maggie 2650's will drive very close to stock and still have the ability to make in the 1,000 to the tire area. They are definitely more prone to heat soak issues however. As far as peak performance and the "cool" factor goes, its going to be tough to beat a well thought out centrifugal setup, the boost is more efficient, they can be as quiet or obnoxious sounding as the user wants them to be, but in my opinion can take away some of the street-ability depending on which blower is utilized.
At the end of the day, both setups can make for fun street and/or race cars depending on the intended use of the car.
Let us know if there is anything we can help with.

I have an A&A SI kit on mine. I did the install myself and it was not too difficult. You and a friend could probably knock it out in a weekend if you've wrenched on cars before. The power is not necessarily immediate but comes on so low the at it might as well not make a difference. You can instantly tell when you are in boost, it is like hitting the powerband on a 2 stroke. I suppose some of that is tuneable. I had mine tuned for $600 by a shop. I've had it on for 5 months now, no issues. 588 rwhp but jesus it dusts everything it goes up against.

The modern PD blowers are tough to beat. I make 608/610 on only 7 psi of boost with my Whipple! Barely even taxing the motor and it’s a blast to drive. Instant torque everywhere in the rev range makes it so fun to drive. And I can keep the same blower and go upwards of 1K to the wheels if desired. The bonus is that the PD blowers look fantastic under the hood, just like an OEM install.

Nice, that's what I'm thinking of going with. How has your reliability been? Reading the forums here makes me nervous about boosting the car because it sounds lime this motor just wants to fail when you add boost. Did you add other supporting mods? If so how insane was the cost to do them? I feel like if it's going to cost me like $15k to boost the car it would be better to just sell it and buy a Z06. Thanks for the input

I have 4600 miles of hell on mine no issue.. but yes the stock pistons dont live long above 600whp as they are hyper eutectic and crack ringlands. So if you are stock motor keep it down on power and itll be fun.
I am on a LME 377" wet sump FI bottom end, so forged pistons..
I would keep the stringray... but Id end up building a z06 or base lol.
