I have abandoned my attempts to put the M90 on my truck. It can be done but the expense will make it close to an already engineered kit.
Can you guys give me some input on how the Powerdyne is working for you? I have the Non-PI 4.6.
Also, has anyone put their truck on a Dyno with the Powerdyne Supercharger?

I know this is not the popular choice but for me the Powerdyne is very attractive for the following reasons:

-I try real hard not to race so being the fastest on the block is not that important to me, mostly this is for towing.

-The Powerdyne is the least expensive

-The Powerdyne appears to be the easiest to install

-The Powerdyne is the quietest (I just can’t get past the sound of the Procharger. I replaced a set of 4:30 gears just because of the sound they made).

-I think centrifugals should be easier on the drive train

-Last but not least I can get a Powerdyne kit very soon; the other kits would have to wait.

Sooooooo does anyone have the Powerdyne who is willing to share without getting trashed (at least by me). Also, if you have a dyno run can you post it here?

THANKS

 

I haven't gotten my truck dynoed to date but am making pretty good 1/4 mile times on a powedyne. Check it out.

 

A friend of mine has a powerdyne 5.4 supercab on 31" tires stock 3.55's automatic.

He is using the 6psi pulley but only see's 5psi @ 5,500rpm and at 3,000rpm he sees 2.5psi.

From my experiences with it so far it's a really great kit, the bracket and tensioner are beautiful. One highlight is you can buy the kit complete shipped for $1,800 from some places which is half the cost of a procharger kit.

You are limited for how much boost you can make with the powerdyne but still can go up to 12-14psi.

My friend is ordering a 9psi pulley so he hopes to see 5psi @ 3,000rpm. He is EXACTLY like you... doesn't race doesn't wanna be the fastest he just wants the blower to play around some and he also tows a 16' enclosed trailer.

His impressions is he loves it. I recommend the 9psi kit or pulley. with that you should see 4-5psi at 3,000rpm and 8-9psi at 5,500rpm... even 1-2psi ~ 2,000rpm.

 

HTown Trucker,
Thanks a lot, that really helps. Where can I find one for $1800?

Blown2run,
Was there a big difference even with the stock 6lb pulley?

 

WLF,

I am sure you could add an intercooler later on with the Powerdyne, if you so desired?

FYI, two days ago, F150online member, "Boss Lariat" contacted me about potentially selling his Magnacharger (Allen) Roots Eaton M-90 intercooled 4.6 supercharger kit. I would jump at it, but I am too far into the lightning swap project. Anyway, he can be contacted at sidejobbob@aol.com

Good Luck.

 

Thanks iron horse, I know you are approaching supercharging from a whole different direction and I appreciate you posting.

I plan to add an intercooler from the get go. It will be smaller then the one used for the Procharger and I plan to mount it just below a functional hood scoop with a heat/water shield between it and the engine. That way it will get moving air any time I am under boost. I also plan to have Mike T. reburn my superchip for use with the Powerdyne.

I think I have pretty much made up my mind on running the Powerdyne.

Anyone else have information to offer?

 

WLF,
I originally had a Powerdyne in my 5.4 truck, over a year ago, I put in an ATI.
My experience with the P/D was:
POSITIVES:
1) Low Price
2) Easiest to install
3) Decent power gain
4) Quieter

NEGATIVES:
1) Doesn't come with a fuel pump upgrade (highly recommend as the stock fuel pump barely supports the stock motor).
2) Doesn't have a by-pass valve set-up to relieve boost when you let off the gas.
3) Had to send mine back after approx. 3 months due to bad bearings in the head unit, could only get about 3psi boost at WOT. Better after repaired under warranty.
4) Doesn't come with an intercooler.
5) Factory set-up is 5-6psi only.

In my case, I ended up spending a lot of additional money to upgrade the fuel pump, switch to 9psi pulley, had to mod a by-pass valve system and had a custom intercooler made by a local speed shop. After doing all that, it wasn't any cheaper than the ATI kit. I ended up selling the P/D set-up I built up (lost my *** of course) to get an ATI afterall because I kinda lost confidience in the P/D reliability (bearings bad at 3 months!), and also too many other people having bearing problems and the reason it's quieter is because it's internally belt driven but the belts break.

The ATI has been on my truck for about 18 months and has yet to give me any problems.

I'm just giving you my personal experience and two cents as food for thought, there are many P/D users that I'm sure are very happy with them!!

Whatever your choice, you'll love being Blown.

 

Thanks 01screw for your input. The hard part of the decission is that there are used Procharger set-ups available for about the same price as a new Powerdyne.

How much of the supercharger noise do you get inside of the cab if you don't mind me asking? I mean at idle and around town not under boost.

Again thanks for posting...

 

I have a Powerdyne on my '98 4.6 5spd reg. cab 2wd. I also have JBA headers, Dynomax dual exhaust w/H pipe, a Superchip and 3.08 gears for the highway.

I have tried all pullies:

3.12 - 5 lbs
2.93 - 6+
2.70 - 7.5
2.50 - 9

I had to add a bypass valve for the 2.5 pulley, I got from superchargersonline for fairly cheap. I had a machine shop tap the threads into the intake/discharge tubes for $40. I also added a bigger in-tank fuel pump, $110 + one hour labour at the local Ford.

I recently had it dynoed on a Mustang dyno, which I understand reads lower than a Dynojet. It did 250 hp @ 5000-5200, 300 lbs-ft @ 3600. Not huge numbers, but for comparison on the same dyno, a stock Hemi Dodge did 240, and a Dakota R/T showed 190.

 

Thanks johnj for the reply. It seems the power increase will be the same for the amount of boostregardless of the charger. Also, if I understand it right; any boost greater then 6 lps needs a bypass valve. Any durability problems?

 

I have had the Powerdyne unit on for 25,000 miles, with the last 10,000 with the 2.50 pulley. No problems at all so far, running premium gas. With the 3.08s, I get 20+ mpg, whether I drive 65 or 85. I think it has to do with the little bit of boost making the engine more efficient even though I'm doing 20 mph faster.

I wouldn't run an intercooler with the Powerdyne; I'm spinning it as fast as what Powerdyne states is maximum impeller speed; 42,500 rpm @ 5400 engine rpm. You will lose 1-2 lbs with the intercooler, and with the Powerdyne, you cannot spin it any faster. So, I would think that the cooler charge temp could not make up for the boost loss. Just my 2 cents.

There is definitely potential for more power, with some aftermarket cams and even ported heads. Fox Lake and Anderson Motorsport? port non-PI heads with pretty good results.

There is a significant difference in power between the 3.12 and the 2.50 pullies; over one second in the 1/4 mile. Before the s/c, the truck had the exhaust, K&N cold air kit, chip and would do 118 mph. It will now do about 135. It runs like a top.

 

I was reading youre posts I also have a powerdyne on f150 supercrew. I have also spent a lot of extra time and money on it. New fuel pump 2.7 pulley 42# injectors 90mm mass air custom tune rom Mike Troyer and am satisfied with the performance even though always looking for more.

My question i where did you get the 2.5 pulley? As i am in th process of installing an intercooler and i feel the pully may be necessary to overcome the boost loss. I am going to use a air to water intercooler.

 

superchargersonline.com is where to get the 2.50 pulley. I had to run a 1/2 inch smaller belt as well with it.

I'm not sure about running an intercooler for less than 10 lbs boost; I would look at maybe an alcohol injection system instead. Cheaper, effective, no boost loss. If the Powerdyne could be spun faster to make up the boost loss, I would go with an intercooler, but 9 lbs with the 2.50 doesn't cut it in my book.

smcenterprises.com makes alcohol/water injection systems, check them out.

 

WLF,
The noise of the ATI is not too bad. When it was new, there was a kind of "clacking" sound but as time when on and the blower got "broken in" that sound mostly went away(just a little now). Now the most noticible sound is a whistling at idle, once you start to move, there's not much of a noise at all.

The other thing I forgot to mention on the Powerdyne was that adding the air to air intercooler took away about 2psi of boost, so even with the 9psi pulley I would only get about 6-7psi max. The ATI gives an honest 8-9psi and even more with mods to the filter and intake duct.

As I stated earlier, this is just my two cents but I really think that you'll be more satisfied with an ATI (new or used) over the P/D. Like I said, I tried many things with the P/D and never was satisfied with the performance or reliabilty reputation of the unit. When I sold my P/D set-up (about 6 months old) with all the extras, I ended up losing about a grand!!

 

Like you I got enough scratch together for a new Powerdyne kit (might try to keep saving for the turbo kit) but upgrading to 9PSI would entail more parts & $. You will probably be happier with an ATI kit.

Also, consider this WLF. After the the turbo orders start going out there will probably be a good surplus of used F150 ATI kits available, hopefully for reasonable prices.

Just an FYI, but the magnacharger and every other supercharger in the classifieds at this time are all for 5.4 engines. Which ones are adaptable to the 4.6?

Good luck and keep us up to date on what you do.
