I don't remember anyone else trying to make this personal.
I hope your not either!

Nobody, yeah, we actually did the final assembly, why in the world would I lie about such a thing? I will give you a bit of info so you can get your facts straghit. Calling you out? Are you 2 or 5 years old? It's called facts, to claim to be an expert if you don't know what your talking about.

Did I assemble them? Not all of them, but I certainly did my fair share. THere was a team of 4 of us that once recertified over 100 R980's in 1 week. Just rebuilt one last week.
How many did we sale, 300 brand new units and some are still going today!
We rebuilt and or SFI recertified over 2000 (use to have to have SFI approval every year) over the years.
Why don't we build them anymore? THere was no need for them after NHRA's rule makers allowed PSI to continue to make changes after the "blower freeze" was made. We followed the rules, others did not. We also had to SFI spin test them every 2 years which cost $20,000 in order to be able to recertify the used SC's. This was pointless since we were out of the business. Once the rules were made, ours sales dropped instantly. Market fell out. We knew they would be needed in the future, but at the time, most of you guys were arguing about who had the best 1471 even though the screw compressor was setting records in every class it was allowed.
Why are we not building them now? Who says were not working on it? Were working on a bunch of new things, I'll leave it at that. The market wasn't ready for the 980's, now they are just getting there and there very expensive SC's, making 5-10 really doesn't make good business since. We have to build 25 at a time and they will still run over $8000. At this point, I would rather sale a couple of thousand mustang kits or 500HP's. I'm not sure how big of a market you think there is for such a supercharger, but it's no where near the smaller SC's.

How does racecrafters get away without calling them Whipples? How can I dictate what a consumer does with his property? Can you buy a Ford and take the logo off or will the Ford Police come arrest you, fine you and make you reinstall the logo? After all, it's a Ford?

Does Autorotor still make superchargers for us? No, it's actually Lysholm Technologies who cuts the rotors. We haven't used Autorotors since 1995.

As for your 2 blower theory, you need to do some research. Size does not equal efficiency and airflow can only give you a therotical power level. Put two M5's and you'll turn them so slow that the efficiency will be off the charts and not in a good way. Run the airflow up and sure, they may make more power if the engine can withstand it, point is what? It doesn't matter if you used 8 superchargers, if you flow a given amount of airflow more efficiently, than you have the ability to make more power or better yet, waste less energy operating the SC. So the point is, the dual 3.3 or Quad Rotor can generate cooler air more efficiently than the marine PSI at all power levels below 1600HP. Put a A980 on a 350 Mag and run 6lbs of boost, sorry, won't work really well. Instead of wasting the power robbed from the M5's why wouldn't you use turbos and get back all that power loss?

As for Mercury, I won't give you that type of information, but we own the rights to anything less than 5000 units per year, per application, pretty basic, have a 8 year contract. Also, not sure how many motors you think MR makes a year, but with that qty, nobody's getting rich. We sale approx. 12 times more SC's then they will. As for fuel both ways, I can tell you, as could the engineers who tested it at MR. It makes more power, both low end torque and top end HP. The best system is a blend and that depends on the amount of fuel, cylinder head design, etc. but running fuel through the SC under boost makes more power. It's a cooling median, gets prepared for better atomization and seals the rotor to casing tolerances for higher efficiency levels. The most efficient compressor is an oil flooded screw compressor because they use the oil as the sealing agent between the casing and rotors. THe final designs were with port injection only, but not for power reasons.

As for dyno pulls, I've been around 3000hp motors and plenty of top fuel motors at the track, not sure if you know, but I've been friends with Gary Scelzi ever since I was a little kid and that guy named Alan Johnson. My father owned a funny car called the "revelloution" with then driver Ed "the Ace" McCulloch, maybe you've heard of it? Or maybe you've heard of my grandfather, he had the first top fuel hydro to break 200mph, called Mr. Ed. So I've been around some pretty wild motors and I'm not even touching the TRD IMSA motors, TRD CART motors or anything of the sorts. I've been around racing my entire life and I didn't just go to the tracks, I got to work on cars, evaluate data, work with crew chiefs with our air fuel meters, R980 and A980, etc. I don't need to have a video showing my credibility, I'm brave enough to actually post my name.

I feel I do ok at EFI but then again my Dell laptop is missing its logo so they've been looking for me, they said I can't go around telling everybody it's a laptop, it has to be a Dell laptop. What am I going to do?

Not sure why your quizzing me, this is not a debate, as I said, I support our customers, after all, your nobody, right? Want answers to your questions, buy a supercharger that this information is applicable.

Dustin

NOBODY asked: I don't remember Dustin EVER saying he was/is a professional engine builder. Those ridiculous questions have tarnished my picture of you.

Let's do this, why don't YOU answer the questions and I'll bring the smack this time.

Preliminary smack ... It's comedy hour at OSO

I can not wait for JC to get here......Thunderuos Chicken you are still talking S H I T....This is going to get very good with alot of education spelled out.

Birdman, are you and JC going to (Learn) me with your higher education? Looks like you have already been sent to school several times. Since you haven't absorbed any of it.......Bring it on! I think one of you said earlier "welcome to the lions den" LMAO. You guys are real good at dishing it out but don't take it very well.......Hey Nobody...it is directed toward you...you seem to have a hard time figuring that out. Bring on your best gum bumpin but get ready to get your feelings hurt.

I for one am learnig quite a bit from the differences, if everyone would keep things in line I'm sure this thread can stay alive for a while. If the cheerleaders for each side can keep things sensible I am looking forward to hearing what Dustin, Nobody and the guys have to say. just my opinion...Rob

i tell you what, everybody on here arguing they are the best at what they do, just send me whatever you build or design, and i will test them this summer for you at LOTO..... it might be the only way we get to the bottom of this, i will do it for the betterment of OSO.....

keep the info coming, but no need to make it personal..... and if you are hiding behind a screen name, come out and say who you are and what you do.... that way we can have all the facts and form our own opinions

A lot of knowledge, emotion and ego here.
Great Thread!

it almost has gone apache.....
