squeezing more out of powerdyne

BlOWN-EA · 07-08-2005, 04:20 PM

any one know of someone or actually done them selves, put a smaller pulley on their powerdyne supercharger, how much more boost can these really take before they break and wat is it that breaks in them, how long do they last till they do em'selves?

Umm i believe JMM did it to run 12psi, but were constantly blowing it. Powerdyne's use an internal belt rather than gears, and the problem is that they are only rated to a certain RPM before to much strain is put on the belt and it snaps. I asked a few places and they all told me that you really don't wanna be pushing much more boost from them, maybe 10psi max.

I was told that it is recommended to change the belts every 40-50,000k's (if memory serves correctly). Also, if you leave the blower for 1-2years or so without being used, the belt tends to dry out and become brittle causng it to snap (that's what happened to mine, well that and over reving :P). The belts are $170 so it's not incredibly expensive to replace.

I would leave the boost as is and spend some money elsewere (ie cam, headwork, exhaust etc).

PS, what mods have you done and what power you getting out of her???

ummm, got:
stage three cam
ported and polished head
veriable cam timing
manual, 17's, minispool
9psi cappa kit, chiptorque chip and dyno tune
thermofans, the clear indicators, new paint job
ultra lows, etc etc

oi rmyers do ya reakon the intercooler was worth it considering a front mount for mine???

BlOWN-EA · 08-08-2005, 10:13 PM

oh ya and 223 rwkw
im thinking of upgrading the blower
to powerdynes XB-1A 18psi blower
and is a direct swap with the original.
hmmmm.. if only money grew on trees

LUXO_8 · 08-08-2005, 10:17 PM

223rwkw isnt too shabby mate!!
nice stuff.

chuck some pics up in the EA-ED pics thread in the showroom

Sounds like a nice setup (i shoulda gone petrol lol). Umm i never did a back to back comparison of the kit with and without the cooler, but it's be a must before you upgrade the blower. Also upgrade your exhuast to a 3inch if not already done.

BlOWN-EA · 09-08-2005, 07:14 PM

oh ya exhaust has been done and the extractors too been done.
i gotta get my hands on a digital camera

BlOWN-EA · 09-08-2005, 07:14 PM

how much was the intercooler setup?
much pressure drop?

dansedgli · 09-08-2005, 07:17 PM

Your not curtis are ya?

EDXR8 · 09-08-2005, 07:18 PM

Some of the US 5L guys are running 11psi pullies on the powerdynes but it doesn't seem like they last long at all before breaking a belt or worse. Intercooling isn't all that efficient on Powerdynes from what I have read because they produce a relatively cool charge and the pressure drop the IC causes more power loss than the cooler charge creates. Best bet is upgrading it to a XB-1A or even better a Vortech.

The setup cost me about $1300 including all the 3 inch piping aswell. The boost gauge shows a little over 8 psi so it's a pretty small drop if you factor in how much the engine itself takes aswell...

my mates NA Fairlane makes 255rwkw and its N/A
Note: 4.6ltr stroker

Walkinshaw · 09-08-2005, 08:21 PM

Btw blown-ea, how have your experinces been with the powerdyne?? How long you had it running for???

BlOWN-EA · 09-08-2005, 09:58 PM

first who is curtis???
and ya ive had the powerdyne kit for ages now and had no problems what so ever, prob cause i installed it my self of course, which means dodgey. butwe wont go into that. nah but its good. wat about u rmyers???

Who cares. Do you want a longer stroke in the 6!!! I don't.

I've only had it running for about 2 weeks before my torque convertor shat itself :P So that's why i asked. I've heard of people having problems with stuffed bearings but i'm led to believe that it was due to dodgy brackets and overtensioning the drive belt.

EDXR8, i've read that aswell (about the cooler decreasing power), but it's still something you'd want to do before upgrading to the XB-1A or a vortech as they are gear driven blowers and wont be putting out the relatively cool air charge that the belt driven powerdyne does.
