My car is a daily driver. It makes the commute so much more palatable. I have a
Vortech V2 (centrifugal) blower with a conservative tune. I told the tuner that it was a daily driver and asked that he keep the tune very safe, accordingly. He also wrote a second tune that's more aggressive for track days.
Vortech has been in business a long time with a reputation for reliability. Also, as centrifugal blowers make more and more boost as rpm's rise (with little boost in normal driving at lower rpm's) they aren't as hard on your drivetrain.
There really aren't any "bad" blowers on the market, so it really comes down to getting a proper dyno tune to keep things safe & reliable.
Best bang-for-the-buck? That's very subjective and you'll get a heated debate going with that question. I believe the Vortech V2 or V3 is great bang-for-the-buck. I paid $3,700 for a brand new V2 last year (non-intercooled) and gained 140 flywheel hp. That's only $26 per hp. Even adding in labor, custom dyno tuning, and a few miscellaneous parts, the grand total was about $5,300, which is about $38 per hp.
Compare that to the FRPP 500 flywheel hp blower. Parts and labor averages about $7500 for that set up and nets you 200 flywheel hp improvement. That's also about $38 per hp. Same cost per hp, just more power & more money. That's kind of par for the course. So, they're both great bang-for-the-buck when you compare what you get for the money you spend.
