How have you liked your powerdyne supercharger? Is it worth the cash? About to put one on my 93 Heads and cam package LT1 but wanted to know if it was worth it. Is there any modification needed to be done? I already have a high volume fuel pump and svo 30lbs injectors so fuel is taken care of. Can you add intercooler to these set ups? Thnaks to all those with info.........

 

As long as you dont try to push to much boost out of the they are great. I wouldnt go bigger than 6# pulley. I had a 4.5# on mine and it hit almost 6psi every time i slammed on the gas.

 

well my car makes 430 RWHP right now so i thought this kit will help me get to the 500 HP mark. Any thoughts on this?????

 

well mine added about 70-80 hp with the 4.5 pulley .

 

If your car is trully at 430 rwhp now, I really don't think the Powerdyne is going to be of any use to you. Your engine is flowing air too well for the Powerdyne, and you would have to overspin it to get boost out of it. Bob

 

yep it will never get you to the 500 mark. doesn't move enough air.

it will be worth a whopping 20-30 hp on your motor if that.

 

my car with powerdyneandcam is 340rwhp
cam only (the same cam) 383rwhp

 

so basically its worth some power but not much.....

 

looks like its worth it on stock cars, but it wont help much on cars that are already pushing alot of power.

 

Sometimes I think Powerdyne gets an overly bad rap. I think the kit itself is flawed in that its not intercooled though. It just has a 90 degree elbow between the Head unit and your TB. I think this causes nearly all of the performance problems of the kit.

Firstly, it pumps heated air into your engine. When air is compressed it heats up, ALOT. Everyone knows hot air is less dense than cooler air. So even though it may create 6lb of boost, since its 100 degrees hotter it gets crappy effeciency out of the said 6lb. I think an intercooler would help this ALOT. I think every other centrifugal kit on the market is intercooled and put out ALOT bigger numbers........ hmmmmm

Secondly, with only that small elbow to store boost in I think it loses out on some of the linear power it could put out. Ever tried using a grinder with a 5 gallon compressor ? You have to stop every 30 seconds to let it build up air pressure again...on the other hand with a 50 gallon compressor it will hold the same PSI for ALOT longer. So I think an intercooler and the extra piping would help it to store boost and keep the power delivery smooth.

Lastly the belt snapping problems. Again I think this is a result of the small area for the boost to go. In quick off throttle situations when the throttle body blade snaps shut..there is nowhere for the boost to go. And with such a small area it must build up some huge pressure in a hurry. No wonder the head unit backspins and pops the belt. Once again, if it had an intercooler and all the associated piping, with more storage space to fill...the pressure wouldnt spike so easily.

I would really like to see a powerdyne setup with a nice big front mount intercooler. I almost tried this myself, but the guy selling me the head unit bailed on me =/

Now I"m going procharger...so I guess I"ll never know
