chucks bp,
I have heard this several times now about belt slipage. I think I will be proactive and just go with the gatorback. Do you have a length and were did you get yours?

 

I read an earlier post on the Gatorbacks and had already switched to one. I didn't notice a difference though. Maybe something else is wrong or Powerdyne's are just crap.

 

the part # on the belt package is 4060650 this must be a comon belt for some application as the local parts store stocks this belt. Try youre local parts store or you can mail order through Troyer performance. This is the belt I am using on my 4.6 with a 2.7 pulley. it is a little hard to install at first but once over the pulleys alows for ample adjustment. The belt that came with the powerdyne was so loose that the ribs touched together befor the belt was tight enough. Also be aware that the idler pully bracket is ofset when installing this belt put the belt over the crank and supercharger pulleys with the idler removed then install the idler in the proper position re tighten after 250 to 350 miles, and then it will be fine for a long time. Hope this helps, and good luck!!!

 

Thanks chucks bp, good info. I will have to check with Mike for which one will fit with the stock 6 lb pulley.

 

Well, yesterday I did what I think is the hardest part of this install. I installed a Walbro 190LPH (model number AGCA745-1) in tank fuel pump I purchased from Troyer Performance. Why the 190 instead of the 250 you ask... Here is a list of reasons:

-The 190LPH will support 475 charged HP and 525 NA HP, plenty for me "and most I suspect".

-The 190LPH pump cost less then half what the 255 costs and includes the installation kit

-This fuel pump is a direct replacement, no modifications needed. No cutting the original bracket or worrying if you left enough space beneath the pump to flow. Even the wiring harness from the original sender just plugged in. The only thing that sets this pump apart from stock is the 190LPH is about one inch longer then stock. It even came with a rubber sock like stock and came with a new fuel filter.

I got a check engine light and had it scanned at Autozone. It came back "fuel evap system sensor high pressure reading". When I checked I found the electrical connection to the evap system sensor had come off. High must be the default reading.

Some have said this is a 45 min job. I removed the tank and cleaned up some surface rust while I was working and it took me 5 hours total. Expect this to be a 4 hour job if your working off the floor of your garage like I was. Also rate this a 3 1/2 of 5 wrench for difficulty. Especially if you do-it-alone like I did.

Next I will be changing over the lower pulley/damper.

 

You can buy the 255lph pump all day long for $90 new.

So what if you gotta cut the bottom part off the stock bracket it still works the same.

Save money and mod more > spending too much for parts.

 

HTown Trucker,
You should post the site where you found that price so others can benefit. While you’re at it, post the site where you found the Powerdyne set-up for $1800; the best price I could find was $600 more.
Anyway, to each his own.
Others plan to upgrade to the point of needing the 255LPH. I won't need that much so I prefer not having to modify the bracket.
What I post here is just to let others know what MY mods are, not a guideline for what THEY do. If we post ALL THE OPTIONS then others can decide where they fall in the space time continuum of performance modifications…

 

I got the Powerdyne today. Everything looks ok. Now its to me to be patient. I will start bugging Mike tomorrow about the other parts. Try to be patient, Try to be patient, Try to be patient, Try to be patient, I just keep saying that to myself...

 

Yes, 42LB injectors, 90MM MAF and 4 program chip.

 

I spent about an hour and a half smoothing the discharge tube today (the aluminum tube between the supercharger and the throttle body). It is cast about 3/8 thick on the ends and is as square as can be. I got out the drum sander and my port kit and made the transition as smooth as silk. I recommend anyone getting this kit to take time to do this. It just can't be good for flow. Now I am going to try to figure out where to put the by-pass valve.

 

Hey WLF!

Good luck with the Powerdyne! Before I found my deal for the used Allen kit, I was going to get a used Powerdyne too!

 

The lowest price that I found a couple months ago for a new Powerdyne was at Fairway Sport & Performance in So Calif. Total cost to me was $1895 including shipping.

 

Thanks CoolF150, too late for me but here is a link for others. I cannot verify price on the internet but it may be worth a call to them:

I installed one of the by-pass adaptors in the spacer that holds the idle air by-pass. It is made of powdercoated metal and was a good place. I used plastic epoxy in addition to screwing it in so I was able to remove the excess adaptor from inside the tube. I did this so it would not alter flow. I installed the other adaptor in the plastic elbow just before it enters the supercharger, also with epoxy and removal of excess. Yesterday I installed new Accel coil packs. Today I am going to install the new plugs. Then I plan to install the lower pulley on Thursday. I spoke with Mike Troyer on Monday and he said the Injectors, MAF and Superchip will be to me by Thursday so the install of the rest of the kit should be Friday night.

Wish me luck…

 

GOOD LUCK!!

Can't wait to see how things turn out. BTW, I appreciate (as I'm sure most members do) the extra time you and others take to keep us updated with the projects they are doing and how things progress. I suspect you will be happy with the results. I've read about lots of people who've have done the Powerdyne but only few have included a good tune along with it.

 

I just got word my Superchip will not ship until today so it looks like final instillation will be some time next week. I am going to do a mock install this weekend to see where the intake goes. I don't like the flex hose Powerdyne uses between the MAF and the Supercharger so I am going to try to fabricate something out of 3 1/2 inch CPVC (the same size as the flex hose) that will be smoother and flow better. I can use some of that new paint that adheres to plastic to paint it when I get done. If it works out I will post pictures.
