How much Boost on Stock Motor?

[1995MGTS]

Powerdyne does have a bad reputation with their blowers. It seems they don't have much in the area of quality control. Meaning, it seems some of their blowers last while others break with relatively few miles on them and then continue to break over time for whatever reason.

However, with that being said, I normally don't recommend the BD-11A Powerdyne not because of its history but because of its growth potential. There really isn't any. 9psi is the max of the blower. Someone may run a bit more that but they will be out of the efficieny range for it and really putting the durability at risk. I am following a local racer with the new gear driven Powerdyne, the XB-1. He was recently on the dyno before me and made some really good numbers untuned. That is the best way for me to go since the head unit bolts right into my existing brackets. I would say if someone had the money to buy a new kit, why not just buy the proven S-trim for the same cost.

Now, my friend with the Powerdyne has over 50,000 miles without a problem. I have over 4000 miles, 39 dyno runs, about a dozen quarter mile passes without as much as a hiccup. Maybe ours were built on a Wednesday. They do break but the fix is not that expensive anymore and the internal belts and bearing can be bought for $100 and installed in your garage.

All I can say though is listen to those people who have experience with the blower. To many people read about Pd's and then comment that they suck when in reality they have never used the product. That happens with a lot of products actually. I have also never had a problem with their customer service though that could be because I have yet to have a problem with their blower. I suppose the attitude could change the moment my blower needs some fixing. They have replaced a part under warranty without any questions asked and in a timely manner though. Anyway, it's good to know the history of Pd so you can make up your mind and know that the possibility of internal belt breakage is there but the flip side of the coin is that they can last and do make decent power (see my sig) for a little blower.
