2000 ? 2psi
2500 ?
3000 ? 4psi
3500 ? 5
4000 ? 9psi
4500 ? 9psi
5500 12psi with intake mod.
this is with the stock pulley.

Also, is there a bypass valve so I wouldn't be blowing all the time, even under no load conditions? The blow off works on vacuum. It blows off to intake as to keep positve pressure so when you mash the gas it boosts and does not under normal driving so as to keep wear and tear down on the motor.


1 Last question: is it worth it to pay the little extra for the D1 upgrade? NO. Unless you plan on using the full 32 psi. as opposed to the P1 at 30psi. The d1 is the same as the P1 with the exeption of the bearing on the impeller.

Hope this helps.

 

I am very grateful for the psi boost info! Thanks! Frank

 

This is the kind of information I've been looking for in regards to my decision to go for a roots type system, or centrifugal.... One question I have is, can a different pully be used on the ATI get get more boost sooner (lower RPM), but have the peak boost limited to 9-10 PSI (or what ever is reasonable)? There was a good series of articles in the lastest issue of "Truckin" magazine, which got me thinking more towards the ATI, and less Magnacharger - I like the idea of positive displacement, but not the complexity (of the installation). I'd really like to find a Whipple SC for the 5.4L.....

Crash!, Skidmark, keep the info. coming!

 

Crash/Derek - does your bag of TRIX package cause moore boost to occur at lower rpms on the ATI?

Do you have a demo at your dallas office? I may be up there and would maybe be interested in learning more.

Hey crash - tell me about that white ford on your web page that's burning the tires down to nuthin. Is that ATI?

 

First, thanks for keep answering questions for those of us that dream SC dreams.

In following the posts, you seem pretty tickled with the ATI, and I was really glad to see your response to Frankinaustins request for boost vs. RPM.

While I absolutely do not baby my truck, I don't race either. Seriously, I normally don't see over 3 - 3.5k on the tach-o except the rare "gotta get around this slow-poke quick" move.
I find the 5.4 accelerates in traffic quite nicely with moderate throttle.


Would you still recommend the ATI? Sounds like your bag-o-trix may help low RPM boost, but I was kinda looking to get an idea of the performance I could expect with my daily driving habits. The ATI builds a nice boost at high RPMs, but I'd rarely see that from the stock setup.

Thanks a ton!

 

HI!.... YA BABY!!!!!!!!!!lol! I need more power! .... and line lock.... and new tires......and........

 

If you want your HP in the lower range then you will want to go with the magna. If you want max HP then go with the ATI. I personally find the ATI a good all around blower. It gives boost at low rpm to aid in pulling but also give a steady build in boost vs. rpm wich is highly tunable for street or strip.

 

Hey Skid, what are some things that can be done to a stock ATI to make either better quality power in the lower RPMs of just plain more power? Will 30# injectors and a big MAF do anything? Smaller pulley worth anything? Frank

 

There are several things that can be done. We have unlocked a few of the secrets. You can go with a smaller pulley (but that will void warranty) or you can go with a modded blowoff that will allow boost to come on faster. As far as the maf and injectors at 10 psi or less you will not really see any improvment. After that however it is recomended. As far as power on bottom only a modded blow off will help. My truck (the blueone) created boost at just off idle. However you do not want alot of boost on bottom. My theory is to leave on motor and build boost gradually until you are about to chuck a piston (30psi) and have fun. With this setup it is easy and more fun to drive because you are not fighting the truck trying to leave the line and smoking the tires. Now at 30 psi traction does become a factor on the big end but if you keep it at 15psi or less then it is not a problem.

 

Do you really run 15 psi at the max? I thought that would cause the motor to explode??? This is exciting! Do you sell a modded blowoff? Know where to get one? Does it also tell the computer that mass air is getting wastegated so as to to richout? (does this make sence?)

BTW, your very specific responses to my annoying questions are subpurb! Quite lucid! Perhaps you could get rich by selling a superchargers for dummies book??? There really are gaps in the body of knowledge regarding superchargers in a streetable EFI environment. {{no fooling - the publishing market for your knowledge may produce more wealth for you}}

 

I have run more than 15 psi on a stock motor. Normal everyday driving it pushes about 6 psi unless I stomp it then is goes to 12psi. WE are working on the modded blow off so that we can get it into production. Right now they are a one off deal. As far as the mag anything 12psi or below you can vent to intake with no problems. After 12 you will need to vent to atmoshere or you will encouter problems

 

Following is my conversation with www.superchargersonline.com for anyone interested in the ATI. I am very seriously considering an ATI unit at the end of December...

"Noticed you sell the ATI kit at $3499.00. Is this the
correct price? I am looking for a bolt on charger
that doesn't tap the oilpan and is relatively easy to
install. Does this unit or the powerdyne more
accurately fit this description? I have an 01 Screw
5.4L... Any other reccomendations are most welcome.

Thanks,

Ken"

"Ken,

That is the correct price. The ATI will be a higher performing, higher
quality unit compared to the Powerdyne. The Powerdyne is an economical
entry-level supercharger. Both are self contained and easy to install.
Definiteley go for the ATI if you can afford the price differential."

 

AMEN to brother Crash!!! This is the key here guys and gals. When looking for a performance mod and the word cheap comes to mind then well you need to think of something eles. Cheap means leave it alone. I race bikes etc. I will gladly spend a few more dollars on a part that I could get eleswhere cheaper just for service and support. You buy a product from a company and they cannot support it, then you have a problem and you are stuck with a headache. I spoke with crash at length on this and here is my feeling. If you can find a blower (brand we offer) for a lower price- we will try to match that price. If you choose to buy from another vendor that is your right. We will install any blower system on any truck. We will tune it for you as well, But if the blower was bought from an alternate source, we only warranty the install. Example. Bought from us installed by us, you encounter a problem we fix said problem free of charge (labor), parts etc go by man. warranty. If you buy somewhere elese and we install it and you encounter a problem not related to install then you will be charged for any work done. I have been in the retail business for a long time and anyone who has bought a product with a warranty will agree, IT IS ALL ABOUT THE SERVICE. Buy a truck from a dealer, it breaks, service sucks, you will not buy there again. We cannot say you will not encounter any problems with any of our products, but we can say that if you do we are on your side and will do all in our power to correct the situation promptly and with as little impact on you the customer. Keep in mind that I have a day job and so does crash. We do this to help our fellow ford'ians go faster. This is a hobby for us not a job so we actually care about the fit and finish of an install and a product. We are here to make friends period.

 

Let me start out by saying that I don't question your knowledge on this topic of supercharging our trucks. I will also say I don't know jack about it except for what I read. I have never worked on an engine in my life. That being said, your big statement a while back, when pricing was being discussed, was that Superchargers online "will not sell at that price. Call or E-mail them. Been there done that." These were your words. Now that that price has been confirmed, you're changing your story. Now the other place is no good because they don't do installations. If your going to do the install yourself, what's the difference? Wouldn't the warranty be directly through ATI? You guys might be the greatest thing for people that want to supercharge their vehicles, but sometimes you come across in a negative tone. I don't know, maybe it's just the way I interpret the posts.
