Looking for new blowers, any opinions?

No Worry's Mate! No I'll thoughts at all, What I meant by a believer is how well these Turbo engines actually perform meaning:
1) No Turbo Lag
2) Power in all ranges
3) And Throttle response
Amoung any and all other Turbo Stigma's

Could really care less about the dyno argument, boat will never spend anytime there anyways.
Only reason for developing Power and boost low is for getting on plane. With the compression so low there is no Static Compression like in a blower application.
You are relying on the Turbo's !
Earhart has it figured out

Hi Jon, thanks for the plug! I am looking forward to seeing your project run again.
Brad, you raise a good question. Turbines aside, how do we get beyond 1500 HP with current state of the art engines?
Better fuel? No, already running race gas.
Better heads? No, already got the best.
More RPM? No, valvetrain is already stressed.
More boost? No, intercooler is already too small.
And yet several engine builders have reached 1700 - 1800 HP using centrifugal blowers whether belt or turbo. How did they do this?
more boost with much bigger intercoolers
lower parasitic losses with more efficient blowers
These engine builders and the customers behind these projects are pioneers. Setbacks are to be expected when testing any new application; this is the only path to success. But important milestones are being reached. Sterling uses our single centrifugal race system on their Class 1 engines and they can qualify first and finish first.
I understand the customer who sticks with the status quo; who wants to go boating without hassles. A number of engine builders can sell you a reliable 1200 HP pump gas package. But some guys like to stretch the envelope and they deserve respect because the R&D they pay for trickles down. That's why you can buy a 1200 HP pump gas package today.
Just wanted to push back a bit for the centrifugal guys. We're not dead yet.
Thanks,
Tom
