TVS2300 vs centri supercharger
Hey guys. Between the new TVS2300 and the centris (A&A or ECS) was just wondering what you guys think is the best choice in terms of reliability and drivability? I was looking at this article over on edmunds insideline of a hennessey camaro with an ls3.
http://blogs.edmunds.com/straightlin...-the-dyno.html
Take a look at the dyno! The torque across the rpm range is amazing! This is all done with a magnusson 2300 at 6lbs of boost! I am not looking to make more power past about 550rwhp as reliability is a major concern to me. I am gonna go with ECS for the install but now cant decide on which charger to go with, the tvs or the paxton? Please help as I am a noob lol. What are your guys thoughts?

All I know is that the Maggies have a great torque curve, and the driveability is so good that several manufacturers use roots blowers for production cars. Many high performance aftermarket cars use centris because they are cheaper, easier to install and don't need a new hood. They make great power and are efficient.
I went with the Maggie TVS 1900 for my engine.

Has anyone had any personal experience with both types of superchargers?

I think it's more difficult to engineer a good Roots system, but they seem to think it's worth the cost and effort.

The good news is that there are lots of options. After getting along with the TVS2300 for a few days, I wouldn't change a thing. Power comes in quick and just keeps pulling. MCharger reliability isn't questionable.
The centri's and MCharger are easy choices. Techco will get there too. It's good to have these options. They each make the other better. I think I have the best of the best, but I can't argue too long and hard with someone that likes one of the other systems. It starts with the vette......a pretty good platform to work with.

I disagree. OE manufacturers tend to prioritize flexibility( broad, flat torque curve), because it feels better in street driving. The manufacturers like MB can use any system they want, not the cheapest.

For price. If you are MB, you only have to buy the housing and the rotors from Eaton, everything else you make. Im sure for the quantity that they buy, the total cost would be like $100. The gears inside a Vortech cost more than that.

By the way, I believe GM's reference to centris being cheaper means less expensive (cost less money), no indications he is calling them cheap.

As was stated, the two blowers have different power and torque curves. Positive displacement blowers make stupid torque at very low RPM, stay flat through the mid-range and typically drop off a little on the top.
Centris by contrast start out a little softer and then come on harder and harder with RPM. They won't run out of breath and will keep sucking your eyes into the back of your head until you decide to shift.
ECS kind of bridges the gap between the two. Their kit typically makes about the same power as the other centrifugal options but almost always makes more torque. If you look at dyno numbers posted all over this section, you'll see that ECS cars seem to make almost as much torque as power AND produce the torque earlier in the rev range.
My car for example makes 562 HP/556 lb/ft. My GFs car makes 551 HP/541 lb/ft. The curve is a little "fatter" than other centrifugals too. I've got 500 ft/lbs at something like 3500 RPM. The hit isn't like a true PD blower, but it seems pretty close.
The other nice thing about centris is that (while all blowers get hot) they're less prone to heat-soak than a PD blower that's bolted directly to the hot engine.

The ECS setup has very similar torque down low to a PD, with the advantages of the power up top. IMO: OEM's generally don't use Centri's for one reason only: they are generally noisier than PD blowers and new car buyers of MB and such wouldn't stand for that.

Hey JSB LS3! From a seat of the pants perspective, can you feel the power and torque down low (below 3000rpms) or do you start feeling the power later on?
Does the car feel like stock when you get on it before 3000rpms or can you feel the benefit of the paxton blower down low also?
Thanks!

I meant less money as well. It also has to do with which suppliers they can choose from. If they went with a Centri from the factory, they would spend a lot more money on EPA and Carb certifications. Toyota had to do this when they first started to use Vortech's for the Scions. Eaton is already in the door... The accountants still have a say in what goes on.

also consider growing into what you decide on, most never mod their corvette with F.I. and those that choose to, usually think that XXX hp will be more than enough HP, but 99% of the time they want more after they get a few miles on the new setup... 
as for Heat soak and the TVS, just check out the issues the ZR1 guys are b*tching about...
