Planning on ordering a blower today. I am wondering just how slow a centrifugal is off the line with a stock converter and 3.15 gears. I keep vacillating between a Procharger Stage II and a TVS - Roush/VMP.
How Lazy is a Centrifugal Supercharger

Boost doesnt kick in until 3k and then ramps up. You probably wont 60' any better than a 1.8-9 with the stock converter. On the street it wont matter and will still roast the tires from a stop.(unless you are on a MT pro or other good DR)
i hear the v3 with a torque booster is near TVS feel. im not sure its just one ive been thinking about.
That question is too general, compared to what? Laggy enough to get you decent traction on the street where you would have lost it with a different setup. A better comparison would be a boost log comparing different setups at different rpm levels I would say.
They are different setups with different power curves. You can get away with a low stall and high gear with a TVS due to the low end torque. You can't with a centri. You need to put it in the power band off the line to sixty foot well, by either lower gear or more stall or a combo of the two. Its not that its lazy off the line it just needs a different setup to launch in its power band.
with a stock converter and a centri expect 1.7 60'....add a converter and expect 1.4's. gearing wont affect it much.
Centrie's need a converter... Check out this link. Stock gears & converter going low 11's, but could be 10's with converter. Crawls off the line. There's a you tube link in there somewhere...

Thanks guys for the input. IF I go with a non centrifugal then I have to look at the differences in the Ford/Whipple vs VMP/Roush roots type. The Ford is a twin screw. It makes less on the bottom, but more at higher rpms. Cost wise the centrifugal + converter is about the same as a TVS or roots type. I have studied PDF files on the install for Vortech, Procharger and VMP/Roush. It appears that the Stage II Procharger is by far the easiest to install. I need to put my shooting hobby aside for awhile and focus on my car.
So here is a scenario question. You have two A6 Mustangs 3.15 gear, each with the same 625 whp. One with a centrifugal the other with a TVS. Centri car has a converter other one does not. 40 - 120 mph punch. Assume no traction issues. Which car wins?

My cars 60' didn't change after the Procharger install high 1.9 60s is the best it could do. I had to get a converter.
That's a tough call... If they are both the same weight cars & at a 40 roll should start in their power band, same whp, I' say a TIE...
They Centri's claim to make more HP, but the TVS always make more torque, so it's usually a wash...
I will say get a VMP TVS over the Whipple, and also the power band does not fall off on a Coyote motor. Mine pulls 1500 to 7500rpm. My car 60's mid 1.5's with stock converter, and soon to be mid to low 1.4's on stock converter.
I'd say on an auto your going to spend the same amount of money for either a TVS or Centri after a converter & torque booster. Id go with what ever one looks cool to you or if you have a local shop that caters to one over the other. I love my TVS, but Centries make power too...
I'm not sure why people think power falls off with tvs's. Mine seems to keep pulling pretty damn hard up to red line. It may not be as strong as a centri up there, but it doesn't fall on its face as some think.
I don't feel my TVS falls off either. I have had a few Vortechs on a fox body and I can't say the Vortechs pulled better on the top.
Back in the day, the kenne bells couldn't flow enough to match the centris. I think that mind set is still stuck with some people like changing your oil every 3,000 miles. Today's TVS/whipples are much better and get the bad ass look over the centris. Procharger gets the ugly after thought look award

couple of other things to maybe consider.
1. long term reliability/maintenance: you bolt a TVS on and forget about it for 100k, but you have to change Centri oil every 5k and how about reliability on a Centri? how many miles before they need bearings/seals?
2. I have seen a few TVS's injest parts when the motor let go...my motor is stock and knowing I am going to beat it til it breaks that was a factor in my decision.

Same whp centri vs tvs from a roll a tvs wins. I've done that race. Better curve for the tvs. However the centri will make more peak power than a tvs @ the same psi. A paxton and tq booster or converter will still be cheaper than a tvs setup. I'm not sure about the procharger cost.
