Momentum Keeps Me Going
Absolutley, it's a completely stock "imagined" S/C . As you can see the management needs a bit of work after 6K or so, but for an actual "imagined" dyno run, not to bad. Soon I hope to have "imagined" power bumped to about 280 RWHP and fattened ^up^ both the torque and HP curve all a long the rpm range.
The only problem is, every time I wake up in the morning, I forget how I "imanaged" to do that

The reason? You can actually buy turbo kits for the car. I shake my head in disbelief every time I think about those waiting for one of those S/C kits that still haven't made it to market yet.
So as far as which S/C is best, it really doesn't matter. Just choose one you like and imagine it in your car.

MM, when's the next dyno day? (wondering if you can dupliate the #'s from last time)

there are a few SC's floating around now. the procharger version in .au and the rotrex one from knigthsports. also there's the blitz one, and the others in development such as axial flow, and roots style ones. there are probably just as many SC kits out there than turbo kits.
I wouldn't mind finding out what the centrifugal SC's deliver. there's enough engine managment options out there now so you don't have to be worried about tuning problems.
here is a interesting development two speed sc

All of which are prototypes, Australian or Japanese market only or one-offs.
The KnightSports is the closest to a "production" unit, and they will only sell them direct and install.
Blitz pulled theirs from market.
HKS gave up when they ditched Rotrex. Apexi did likewise.
Hymee and Axial are still no-shows.
Petit is still in "pre-production" as well.
There are no superchargers on the market right now that one can purchase today.

damn MM, you have some NICE pics you rotate in and out of your avatar. I'd like to see where they come from and see the originals.
now back to your regularly scheduled debate

Would a centrifigal supercharging(turbo on a pulley) be better for a high reving engine like ours? A lot of people seem to hate centrifugal chargers but at high RPM woudln't they be less parasidic?

Well, (B) is a possibility since I've never experienced (A).

you may be able to compensate for the lag but you always have it with a turbo. just like you can compensate for the lack of torque and power with a NA 8 by reving it more.
I haven't experienced a factory turbo that doesn't give a sense of lag due to non-linier power delivery. wrx's have it, my Vauxhall turbo has it, the turbo diesels at work have it. they all boost from 2500-3000rpm but they don't make any real power there and idle is 1000rpm. that's a lag gap.
but I don't want this thread to diverge in to the turbo/sc debate. they both have their peculiarities. this thread should be about sc experiences and performance.
I think the possibility of a smooth building of boost and hence torque and power from a centrifugal sc would be nice to drive hopefully I will get a chance to experience one.
