Great post AO, your contribution is always a plus.

Sticking your head in the sand isn't very bright, either. More data, to me, is never "trivial." When is having more data, aka information (which I presume is how one obtains an "informed opinion"), a bad thing? Just calling Victor doesn't resolve the lack of data. I've emailed with Victor and I'm confident in his ability to build a solid system. But I simply don't understand the recalcitrance to better document the potential gains to be had from this system. Perhaps that's a sign to stay away from it. And apparently an uninformed informed opinion is supposed to be good enough to convince me to drop $5k! Uh, no. I'm not saying Victor is lying; indeed, I think he's got something really great here and I was hoping to help get it off the ground (and into my car). I still believe that, and I hope this all works out. And I'm very happy for you (seriously) that you are happy with the kit, as is Sean. These testimonials make me want to try it out. But numbers don't lie, unless white-out or photoshop is involved. And that's the whole disconnect in this thread. Gearheads like data, and the lack of it allows these questions to be repeatedly asked. Leaving them unanswered beyond "trust me" is simply unsatisfying.

I said "please." And I will ask again: please go dyno your car. Is it classless to ask someone to dyno their car? If you don't want to dyno your car, just say "I don't want to dyno my car." People may ask you why, and you're free to say "because I don't want to." And that's OK.

Ridiculous, the word is spelled rIdiculous!!!

I'm a fan of all the big HP upgrade options, so carry on.

Good morning fellas
I see we had another night of spelling our names in the snow LOL
AO... thank your for your politically correct and rational view. Very much appreciated, and love the way you slipped your awesome dynos number into it at the same time, you sly dog nice numbers BTW

Anyway... after all of the stirred up crazy ****, I have decided to go to different dyno about an hour away and get a few new runs to post for you all. I have attached a picture of my shop and a picture of my white 89 s4. Now as you can see the car is definitely completely stock and the engine compartment looks like poop, but the car runs pretty well. This car is an automatic and not a stick but it should be close to the same. Hmmmm... that just made me think about something???? Does it make a big difference what gear you run your car in at the dyno, and or what gearing you have in the car?? When I was at the dyno before the car had to be run in 4th gear because 5th went too many MPH. Anyway, I will take this car over to the dyno this week and get a pre supercharged log. Then I will drop in a new supercharger in with an 80mm pulley and try to log all the data that I possibly can.

I surely hope this will make everyone happy. I am open to all suggestions on this.

Excellent, thanks!

I would contend that a stock S-4 being driven correctly is more than capable of keeping up with traffic. Hold the pedal down for 14 seconds and you are going 100MPH plus. It will top out at about 170.
The blower gives you major torque at low RPM so yes you need only step on the gas to move around traffic. Does make me wonder what other drivers around you might be thinking as the red Porsche slices and dices through the traffic... but then again down shifting a stock S-4 a couple gears and blasting by at 6,000 RPM is not exactly subtle either
Real question is do you TELL people you have a blower ? and How often do you open up the hood ? Because if it is for your driving enjoyment alone, no need to talk about it. And Yes I have driven many high powered cars, even a GT2RS with 600 plus hp, fun !!
Even a stock S-4 if you drive it very much at it's maximum on the street you will either be arrested or dead.
I have always thought blowers were neat since I saw a nearly new 1957 Studebaker Hawk with a factory Paxton supercharger

Gotta brag a little!

My suggestion is go to a DynoJet if you can find one nearby. Don't know about autos, but on my 5-speed, we ran it in 5th, but the dyno guy did ask about final gearing. I think his speed limit on the dyno is about 200MPH. Not a problem with the 2.73. But it is with the 2.20. Your dyno guy should know. If you can run it in the highest gear, then it takes longer to get there so you get a little more time to see what's happening with the engine. But it shouldn't make a difference on the final number.

If your dyno is closer to Detroit, let us know. Us local guys have been thinking of having a dyno day and maybe we could combine. It might also be helpful to have my car a point of reference. (Actually I want to see if I can hit 500! )

They usually run the autos in 3rd gear, disconnect the kickdown switch and remove the bowden cable to keep it from kicking down when they hammer it. Looking forward to see before/after results for an auto with the 80 mm pulley.

Just a suggestion but, maybe in light of Victor's post, we should close this chapter ie: thread, and continue on the thread started by Sean and Victor can post results there.

victor25

Thanks for the positive suggestions guys!! Now we are on the right track.

Also I like the suggestion about moving on past this thread and to post the info where it belongs

I think I started all of this. Instead of simply pointing out that there was absolutely no way a 928 engine was going to make 481rwhp with 6 pounds of boost...I asked if anyone wanted to race their 6 pound boosted car against a 380rwhp stroker.

To me, that's a pretty simple way to separate bull**** from truth!

I didn't mean to stir up this much crap. And I sure don't need people in my face, because I elect to be totally honest about products and results. And I'm never going to do work for anyone that feels the need to be in my face.

I detest bull**** and tend to get pissed, very quickly, when I "detect it". Sorry, that's the way I am.

The entire point is this:

Why can't people just be totally honest and not misleading about stuff? It doesn't matter if it is a 900HP engine that can't go over 206 mph, or a junk yard dog selling used parts that should be rebuild or junked (instead of being sold as good enough to install and sending the "install" over to a guy that would never say anything ), or a 6 pound supercharger kit that the guy claims makes 481hp (yes, I know he said, here, that the engine that made this kind of power had way more changes, but you've got to admit....his website isn't all that clear, either!)

Look, no one is going to get rich selling stuff for this tiny little 928 market. Why sling bull**** to make a couple of bucks, when lord knows there's already been/is more than enough "crooks" involved in the 928 world, previously. (And we all know who those were/are.)

Just tell the truth and let people decide what is best for them.

I'd rather see dyno and real ET slips from a real drag strip.That way it doesn't matter what dyno etc as the horsepower curves are different from supercharger to supercharger and also on strokers.See what they do in real world also not just sitting on the dyno.At the track it will tell the real story.Cars will spin too depending on hookup but would like to see also how they perform once out there from the 330 foot to 1320foot(1/4 mile) et and mph .Most cars should hookup by the 330 foot mark which almost all tracks show on the slip.Seeing the time from that point on would give a good indication on how any of the cars pull.No G-TECH or any other slap on device,real track with real timers.

Im pretty sure thats not the medical term to truly describe the issue...but I hold high hopes that medical science can resolve it.


After your..incredible remarks about Mark (ive been on the road for 2 days)..you honestly could not have paid me to do it.

I spose, if what you say about Mark is true, you would probably have let me in on the big conspiracy 5mo ago in our initial chats. I'll let the community judge on it's own.

Ive gotten along OK for decades staying out other people's complicated issues.

Perhaps you're doing me, the favor.

Speedtoys

Nope, but that's where your glaucoma gets in your way.

You are PRAISED for what you build.

You turn everyone else off by allowing an opinion to become personal.

Then of course.."why is everyone yelling at me?" happens.
