I'm just curious to know what people's real world experiences are with a centrifugal blower compared to a stock style roots blower running relatively conservative boost and HP levels of around 10-15PSI and 500HP +/- 100 or so.
I don't want this to be a debate about which one is better. This isn't about which setup has the most power "potential".
We're all familiar with the characteristics of either type of blower, as well as their pros and cons..
I just want to hear some experiences from some people that started out with any type of N/A car, and what they can share about overall driving style, how often you got into the boost (or needed to get into the boost) during everyday driving, or spirited driving). And if anyone switched from one setup to the other, why did you decide to do it? Are you happy?
Remember, this is for street applications. I want to know how happy people are with their setup on the street... not on the track, or the dyno.
I'll get us started. (Even though I've never had a positive displacement setup).
I have a P1SC procharger, 3.7" pulley, 4" powerpipe, Aviator longblock, and a few other random pieces. But for all intents and purposes, it's similar to a nearly stock Mach 1 with a Procharger.
With a procharger, it has great driveability, you barely notice it's there except for the menacing whine. Driving around town, I hardly ever have the need to bring it above 4000 RPM, which means I hardly ever get into the boost. Even if I'm passing, it has enough torque to pass a vehicle at reasonable speed without downshifting or getting into the boost.
When I do want to raise some boost-supplemented hell, I find it kind of a laborious and worrisome process. Before I even get into it, I worry about belt slip issues, especially in First and second gears, which are useless if I floor it.. I usually have to go about half throttle until third gear. Once in third, I have to floor it, let the revs climb, and only once I've reached redline, do I make peak boost. And then it's over quicker than it began.
My point being, I really have to push the car hard to get my money's worth out of the procharger.
I was looking over some datalogs with my AEM Failsafe Gauge the other day that logs Boost, A/F, and RPM. Everything is fine, but it only makes peak boost for a fraction of a second before I end the run.
I don't know if I'd be happier with a positive displacement blower (or even a turbo), but I would like to feel the benefits of a power adder more often without having to push it so hard.
Is there anyone with a daily driver who's happier with a centri over a positive displacement blower or vise versa? Why?
