Funny story: One time I was in the the garage at the Indy 500 and ran into the late great Smokey Yunick, I had my little 5 inch (the new one is 4.4) unit with me and handed it to him. He looked at it for awhile, we talked back and forth, then he turned to his wife and said "Honey you want me to buy this for you, it will make a hell of a garbage disposal." :)

smokey grabbed your five inch unit and asked his wife if she wanted it? :D:D:D

smokey was one of the good ones http://www.smokeyyunick.com/

But he knew he'd have to pay for it. :D

I am looking at water/alcohol kits.


Here is one of the kits I was looking at http://www.alkycontrol.com/page1.htm however I would use a larger reservoir to reduce fill up frequency.

Richard any thought on using something like this post AFSC to further increase the efficiency (lower intake temp/higher octane due to the alcohol) of the AFCS system??

The injection system above can be set to linearly increase the alcohol injection based on boost rise.
And I believe it can be set to come on at a predetermined set boost pressure. Say 5psi that way you can reserve the alcohol for the high boost times.

It would most likely be best to design the AFSC to work with out the injection kit (for fail safe reasons/you run out of water/alcohol mixture) and then add in the water injection kit to see how much additional power can be extracted due to the cooling of the intake charge and the increase of the octane rating.

Comments/ ideas????

A much better thing to do rather than get into bandaid systems like those is to just use an intercooler and then tune it properly. Yes those can work but unless you are running at a track, you don't have need for one.

therm8 10-01-2005 08:53 PM

And the way it's set up, fuel atomization through the blades from the extra injector already provides significant charge cooling, if I'm not mistaken. I didn't think an intercooler was even necessary with this SC (with the "out of the box" airflow increase).

Richard Paul 10-02-2005 01:08 AM

What you suggest is a waste of money and you'll make less power.
If the engine is tuned to run on pump gas with X boost and does not get into detonation why add the coolant? It at that point lowers the heat discharge and you get less expansion. Less push on the rotor.

The only time you get anything out of water/alki injection is when you have abnormal combustion/detonation. It will make more power not detonating then detonating. Always remember that this is a heat driven engine, why put the fire out? :confused:

Ricardo had good results with the water/alki injection but there were very special conditions. Mainly called "War emergency power". This is when the pilot pushes the throttle past the stop breaking the safety wire and going into high blower under conditions not ment for it. Such a time is at a lower altitude then he should be but winds up in a dog fight. You may as well kill the engine then get killed.
So at this point because they had so much pressure the coolant proved helpfull. In fact it worked just like richining it up. Only didn't use all the fuel which can't be replaced until he is on the ground.

Can you get more power with this type set up? Yes. The key word here is can YOU get it. You'd be playing with excess pressure and very dangerous area of tune. If you accept that in order to find the right combination of things you will eat up a few engines. This is acceptable in racing and war but not for the hobby car guy. :(

If you have a few engines in the trailer and a crew that can change them in an hour or two then go for it. Every racer has that sort of attatude or he can't win. This is one of the things that keeps the little guy little. It takes amazing resorces to get more then the other guy. I once melted down two engines in one day on the dyno with the same stupid mistake. That's how you get more then the other guy. :eek:

There is no doubt in my mind that when I ship these someone out there will do better then I have with the setup. But he will have had a lot of experiance and may have blown up before he got there. The ones I want to avoid are the ones who just know they are better at it and blow up their engines and it is my fault. I have story to tell of this in the past.

Richard, what does your Axial Flow SC sound like?

Been to the airport lately. However with part throttle and aircleaner intact you cannot hear it at all. The further the throttle is opened the more SC sound comes out. Never will you get the whine of a roots though. If your buying a blower for the noise everyone can hear so they know you have one then this isn't it. :cool:

Nemesis8 10-04-2005 05:22 PM

Nope - I want it quiet :)

california style 10-04-2005 05:28 PM

but audible when running fast tho ?

rotarygod 10-04-2005 05:44 PM

Audible to you maybe but only audible to those who can keep up long enough to hear it!

Hymee 10-04-2005 07:06 PM

Hehehe.

I've been fortunate enough to hear it. Like a Jet! I even felt it's PSI's and flow rate first "hand". I think it was my right hand, but I can't be sure :)

Cheers,
Hymee.

I still want one of the throw away prototypes for use as a blender.. i think it'd make a great smoothie!

Hell.. we could get Richard to do one of those crazy infomercials.. Richard Paul's 4 stage axial flow superblender and food processor!

I mean.. wow.. brilliant!

How many times has this happened to you? You have a bass, and you're trying to find an exciting new way to prepare it for the dinner table. You could scale the bass, remove the bass' tail, head and bones, and serve the fish as you would any other fish dinner. But why bother, now that you can use Rovco's amazing new kitchen tool, the Super Bass-o-Matic '76. Yes, fish-eaters, the days of troublesome scaling, cutting and gutting are over, because Super Bass-o-Matic '76 is the tool that lets you use the bass with no fish waste, and without scaling, cutting or gutting.

Here's how it works: Catch a bass, remove the hook, and drop the bass - that's the whole bass - into the Super Bass-o-Matic '76. Yes, it's that simple!Super Bass-o-Matic '76

swoope 10-04-2005 08:13 PM

wow,
high school flash back. very nicely done..

dont for get the bat o matic.

Let's not date me, upgrade it the '05 model.
I went to see that guy what's his name who smashes the stuff with a big hammer. The first five rows get free rain coats. 'cause they get wet and worse. :eek:
I could give him one for promotion.
I think his best one was the smash-o-matic. But he had all sorts of toys.
Gallager or something like that.
No, I did not sit in the front rows. :p

swoope 10-04-2005 09:42 PM

gallager is correct as is the sleg o matic.

boy has this thread turned un tech like. nice change!!!

now back to work. hope it is going well rp.

Ahhh, 166 pages and counting. Is there a semi-brief summary posted in this tome of wisdom with any kind of progress report or update? How far along to, or is it now with a working prototype? Any light at the end of the tunnel as far as shipping product? And if it has,or will metamophosize into a product, what pray tell might it's progeny look like, or produce power wise?

Just wondering in Colorado. I've done about as much as I can with brakes and suspension, now..... what I really am starting to need is a better power to weight ratio and I'd rather not gut the car or have to put my name on a P-car Cayman wait list just yet.

globi 10-04-2005 10:24 PM

The path is the goal.

or how did Robert Louis Stevenson put it:
''For my part, I don't travel to go anywhere, but to go. I travel for travel's sake''.

zoom44 10-04-2005 10:44 PM

hehe i sat front row for gallagher once- he even picked on me:)

Ajax 10-05-2005 12:54 AM

I only watched gallagher on TV :(

bump...I've been following this thread for a while, but lost track of it. I don't have much time to read at work :(

Anyone mind doin a brief summary?
