Powerdyne supercharger question
Michael Johnson, P.E.
recommend looking for a used Vortech A-Trim or save a little longer and
get a used S-Trim.
The Powerdynes are easier to install because they are self lubricated
where the Vortechs use engine oil which requires additional plumbing.
Installation will normally run between $400-$600 but be forewarned that
if you have to buy individual components from the manufacturer it will
cost you. If you buy a used S/C make sure everything is included for
the installation.
Running 6 psi of boost shouldn't cause any problems if your engine is in
good condition but a good rule with S/C's is "Don't blow it if you can't
afford to rebuild it".

i was looking at this powerdyne 6lb also.....everyone who replied told
me that they are the worse..
a couple of my friends had 6lb powerdynes with 1 guy going up to
7-8lbs with a pulley.....both friends' s/c broke
they now got vortecs
you can buy a new powerdyne 6lb for $1811
i think installation is charged from 6-10 hours

Michael Johnson, P.E.
design and is generally capable of higher boost/power levels. The
A-Trim is an older design and is less efficient compared to the S-Trim.
There are other Vortech models such as the B-Trim, T-Trim, R-Trim and V2
among others.

My Powerdyne 6# only delivers a 20% increase in crank hp as determined by
recent dyno runs on my '99GT. The first response that I got from Powerdyne
on this discrepency was that my numbers were incorrect and that the Mustang
engine hp was really 215...meaning that I was getting ~43% increase. What???
Their technical information needs reviewing. I still haven't gotten a
satisfactory answer from them, but I recently read a similar result from
another post on this NG. I suggest passing this one up and saving your cash
for a compressor with a decent head curve. This one's going on my truck...

BD-11a? I have that one and run a 9lbs pulley and a power pipe. My
car puts out over 385RWHP which is about 450hp. Just had the car
dyno'd at Lugo Performance...I believe that my motor makes about 305hp
without the powerdyne.
I have heard that the 6# isn't worth it. Because you only get about
5psi of boost out of it. I get over 10psi out of my setup. Power
pipe helps. I used to get only about 7.5psi to 8.
I can tell you this much powerdynes claims of 30-35% with 6psi and
45-55% with a 9psi pulleys is BS. UNLESS, you by other stuff that
doesn't come with the system. Like the stuff listed below with * next
to it.
But then I also have
a 302 with TRW forged pistons
edlebrock intake
*30lbs injectors
*190lph walbro
FMU for 30lbs injectors
*fuel reg.
*rich-lean gauge(you have to have one!)
70mm TB
*77mm pro-M
GT-40P heads(59cc)
1.6 RR
X-303 cam
Mac headers and 2 1/2 exhaust
no smog pump(use delete pulley.
no cats.
*crane Hi-6 with BTM
*MSD coil

I have the 6# compressor (part #K10194-101). I'm not sure what the BD-11a
designation is. The only other mod outside of the K&N filter that came with
the kit is the Borla catback. We actually measured as much as 7 pounds of
boost on the dyno. One crappy thing in the kit is the inlet duct, which
doesn't flange up well to the compressor inlet. It tends to work loose after
awhile. I made a temp fix by wedging a pad of rubber between the shock tower
and the inlet duct to help hold it in place. How does the power pipe work
out? It's got to be better than what comes with the kit. Powerdyne told me
that they are redesigning that part of the kit. From your numbers, it looks
like you are getting about 48% increase at the crank. We measured 265 rwhp
with the Powerdyne. I don't have pre-mod numbers, but the stock GT should be
around 220 rwhp. A whopping 20% increase! I think the Borla catback alone
would account for a ~5-8 hp...leaving the Powerdyne to accound for the other
40.
Larger MAS and injectors would help, but wouldn't make up that large a
deficit.

inlet tube size then that crappy stock one that powerdyne ships with
the system.
