Pros and Cons of the APS Twin Turbo System vs Other Brands of Turbos vs Superchargers
What are the Pros and Cons of the APS Twin Turbo System vs the other vast array of other power adders for a completely stock LS2 or LS3?
How does the APS Twin Turbo Kit compare to the other brands of single turbo systems, and twin turbo systems, and the other various brands of Superchargers??
(not comparing the APS or other power adders to cams and headers or nitrous)

Superchargers are RPM referenced for boost. You always have the same boost level for a given RPM. Turbos are able to make full boost at any rpm which is harder to tune and harder on the bottom end.
Turbos dont have belt issues. Superchargers require much more belt tension eventually cause issues with accessories.
Turbos produce a ton of heat.
Cost is a toss up as most who get a supercharger also buy headers. Turbo cars cant run headers.
Superchargers such as the Eforce are very limited on power although they fit well. If all you want is 550rwhp as those kits produce, just buy an ERL shortblock. Its about $1500 to install a $5700 434 cu inch shortblock and 550rwhp N/A is faster than 550 from boost because you lose boost pressure on shifts. This assumes you are using your stock heads /intake manifold. Later you can upgrade many parts and hit 630rwhp N/A. What good here is that you are resetting the clock to zero on your engine and you can sell the existing shortblock to help reduce costs. I've done stroker swaps entirely free to keep the existing shortblock.
Turbo kits being more exotic, dont have the support of the ECS and A&A supercharger kits. ECS and A&A are forum tuners here with a personal relationship with members. Corvettes are their primary business.
UPP's twin turbo kit has gained quite a bit of support and has been used on 9 sec cars at or over 800rwhp. Pipes have lifetime warranty and now come with turbo options.

I had a 06/A6-Z51 Coupe that had the APS turbo system. It worked very well on my stock car, it ran 507hp and 512tq with 7 pounds boost. Never had in issues in the 3 years I had it on the car. I eventually put the car back stock, sold it and now have a Z06.
The complete system is sitting my shop if you are interested.

I've been running an APS tt set-up on the origonal LS2/A6 since 07.
Bone stock fuel pump with KB bap.
Also has cam and 3" APS exhaust (not cheap).
One word...AWESOME!
9 psi: 620whp/620tq last time on the dyno (about a year ago).
Tons of low-end torque (500+ ft lbs tq @2800rpm)
VERY VERY reliable set-up.
Zero heat issues with stock radiator/fan.
Tuned by Ernie @ Westech Performance (experienced tuner makes all the difference in the world).
Cons: The C6 kit has been discontinued from production in N America.
