1. PD blowers (Magnuson, Whipple, LT4) have too much torque so they aren't as drivable on the street. This is utter nonsense and spoken only from people with experience from years ago (when tech was much different), or people who bought the story and personally invested in the Centri blower. The PD blowers drive EXACTLY like stock until you mash the pedal and when you mash the pedal, power is there instantly. Only in non-experience does this represent "a problem".
2. The other BS statement is that Turbo and Centri (Procharger, Vortech, Hennessy, Hellion) both suffer from lag. This is another argument that is mostly garbage. If you drive a PD and then drive a centri/turbo, yes you will feel a difference and it will "lag" a little comparitavely. However, if you are only driving a centri/turbo...the lag is almost unnoticeable. In our cars, A8, it's not really an issue. Yes, the centri puts out lower torque numbers early in the RPM range; however, every centri car that wants to go fast adds a converter so that they jump to higher RPM's and get into higher torque levels from a dig.
Bottom line is that all of the blowers are really solid options. My recommendation is to find the tuner/mechanic that you want to work with and follow their advice. In any setup, the tune makes all the difference.
Because I have been through this game a few times, I am perfectly comfortable with using a remote tuner. There are also great remote options with Jannetty as an example.  |
Have you owned a centrifugal car or turbo car? I have been doing this work on cars for other people and myself for years on many different platforms (mostly American v8's). For my own cars, I have owned a turbo car, a few roots/PD cars, and now two centrifugal cars... You are showing your lack of knowledge in your comments and leading a guy down a very biased road.
1. The roots charger is all torque when you get in the boost (just search some dyne sheets) and most cars can not put that on the ground, instead they get a pile of wheel spin. I ended up peddling it just to get it moving. The instant torque feels awesome on the street, but makes going fast without spinning a science. I had a CTS-v at 814rwhp (Whipple conversion) that I can compare to my 6th gen now with much less rwhp.
2. The guys I see screaming for a T.C. are the roots guys, and I was one of them. My stock T.C. could not handle the torque in my CTS-V, my stock T.C. in my vette handled the vortex without any issues and posted fast track times than my V did with 100 less RWHP.
3. I have never had a pro charged car with any lag what so ever, you get instant boost as the pro charger is always "spooled up" so long as it's turning. It's nothing more than a bypass valve closing giving you instant boost. You should not try to slam other members and make accusations like they are internet queens and have no real world experience when your answer shows you clearly are one of those. There are a number of good examples on here I'm sure an experienced guy as yourself can find negating exactly what you are spitting out.
4. Out of all the options, I think they are all close/great options just different enough to sway someone based on what they are after manner wise, all of the options drive the same when the valve is closed, this about when you hit the gas and open that valve to actually allow boost to your car.. Each have their own mannerism to it.
The turbo set ups are the best IMO. They are faster and you can tune them to run what boost you want and set up a boost button to bring the power on as hard as you want. They seem to be the easiest on your motor and the most capable. This is an area I have the least experience with in gas cars though. Most of my turbo experience is in diesel trucks, diesels at work, and one G8 we boosted.
