I have the 6 psi kit right now i heard that you can upgrade to a gear driven head unit is this true and if so were to you get the kit? Also what benifits do you get going to gear driven over the belt type?And how could i up it a higher boost level i have to change the crank pulley right,which size do i need to up the boost and were do i get that?Thanks

 

I emailed PD a short while ago, and they do not have them for the Fbody.

 

My guess would be that it's Powerdynes effort to compete with the other blower companys. They were talking up a race blower 5 years ago and it was supposed to bolt to the existing brackets.

It looks to mount the same but you'd need to rig up some oil lines since it's not self contained.

 

I have emailed Powerdyne several times this year attempted to talk them into offering the XB-1A (gear driven head unit) for F-bodies. They do not offer this head unit for F-bodies now and it is very doubtful that they will be offering it in the near future. I even requested a special build for myself for just track (no attempt to meet smog or EPA rules) use by converting the XB-1A Mustang head unit with an F-body outlet (straight) housing. No deal since the Mustang unit spins in the opposite direction than an F-body unit. There are ways (larger crank pulley) to spin the BD-11A F-body head unit faster but the internal belt is the weak lnk here coupled with the fact you will spin it too fast and run it out of its efficiency range.

Only way to really bump up to 8+ lb. boost is to switch to a Vortech or ATI set-up. Of course, for street use any 6 lb. set-up should provide as much power as street tires (drag radials included) can handle. More power with running Et Street or drag slicks is just very difficult to hook up. And ET Streets are not the thing for cornering or "real" (should get some flak on that one) street driving.

Thanks for the reply's. I just wanted to know if i could do this i heard about it i didnt know if it was true. I will be doing my motor over this winter and putting in a 383 i know the blower isnt the best type to use with the 383 but will it work and will it hurt anything by me using it. Off course i know it wont make outstanding glob's of horsepower due to the cfm volumne of the powerdyne but will it WORK????

 

Since you are rebuilding the motor anyway, I think I would build a 396 CI stroker and sell the Powerdyne. I have seen some 396's put out a little over 400 RWHP and without the hassles from a blower.

Yes I think the Powerdyne would work and add some power but if you really want to stay supercharged, Sell the Powerdyne, get a forged bottom end with 8.5:1 compression and run an ATI with 15-20 lbs. of boost with a cam built for what you have in mind.

Thanks Mislman,

I think for sure im going to do the 383 and i really was planning on keeping the powerdyne for now i know its not the best but i like the steathyness of it,plus its brand new i dont even have that many miles on it maybe like 500 or so plus the builder doing the motor said that it would work ok..The cam he wants me to use is 226/234@.050 and 536-554 lift with 114 LSA does that sound ok for a blower, the motor is going to be completey forged and a four bolt main so should it hold up? of course its going to have lower comp. and blower pistion's so do you think this will be ok?
