I want to thank you for all of your self seeking, self serving, self promoting BS. You have further solidified my decision on who I get my motors from. This has been the biggest show of somebody getting their teeth kicked in and not even realizing it that I have ever seen....LMFAO! To think......all of these was free......I would have paid good money to see this debate in person.......

Peace Out!

But I am not the motor builder. Do I think my motor builder would have his ass handed to him by dustin, probably so on whipple part numbers and whipple installs but not on engine theory, or how to make alot of hp.

they sure did,,and as tmp will find out.it didn't last very long.can't wait to see one of these monster hp motors actually get throttled.steady pulls on a dyno for one big number is not even close to the stain of throttling on the water.good luck,should be fun to watch.

The SC's that Racecrafters used are Whipple's so I'm not really sure what your refering to on that statement. We own the rights, we did finally assembly, we were the instrumental force in developing the compressor and getting it to the market. We didn't design the rotor profile, that was left to Svenska Rotor Maskiner, the world leaders in screw compressor technology, but those are Whipple Charger's. We had two versions, A980 and R980. That is 9.8 Liters, is that big enough?

As for Mercury not calling their SC's Whipples, why would they, were competition? Lysholm is mainly in business because of our hard work, drive to succeed and innovative ideas. We paid for the development of every compressor including the 3.3L, we utilize 95% of their sales and are instrumental in getting the compressors to a level worthy of the tough vigors of the marine envoirnment. If anybody doesn't see the similarities with Mercury Racing's lineup vs. ours should have their eyes examined. The OEM's approach some things different, but there are strong similarities.

The marine version of the PSI is smaller than our 3.3L quad rotor. The smaller SC's have far tighter rotor tolerances, have 50 years of superior rotor technology and have superior efficiency levels. The PSI rotor design is an out of patent design from the late 50's and does not compare to the later generation "D" profiles for size vs. flow vs. efficiency.

Theres no doubt a larger compressor could serve a purpose in the marine envoirnment and maybe you'll see something in the near future, for the time being, the likes of Sterling Performance have found tremendous success with the 3.3L quad rotor vs. previous PSI equipped engines and we've had tremendous success with our 3.3 Liter.

As for me treading uncharted territories, I'm not sure who you are or how you may know my expertise, but I can hold my own in the field of forced induction and power. I also don't work with any one person or company, I support our product, simple as that. If somebody with our product wants to hear my thoughts on tuning, EFI controllers, camshaft or head selection, compression, etc. then I will offer my thoughts. I've been blessed with the oppurtunity to listen, learn and interact with some incredibly great minds, many far outside the marine industry and some in. With my fathers drive to understand why something happens and how, I've been lucky to gain invaluable knowledge and learn at an accelerated pace.

As for efficiencies, the turbo offers the highest peak efficiency of any supercharger. The screw compressor and centrifugal are nearly identical in peak efficiency. But very few motors run at peak efficiency. The screw compressor offers the highest possible efficiency through a useable rpm range and therefore it can clearly be called the most efficient supercharger to date. Plot a power curve of identical motors with the screw, roots, centrifugal and turbo and as long as all were sized properly, the screw compressor will have the highest average power.

Thanks,
Dustin
