i have a tired lt1 with about 160k right now and i plan on rebuilding it... i dont know alot about supercharged set-ups. if i go with the rebuild kit from summit with srp forged pistons could i run the powerdyne or maybe a vortech set up? ill porbablly port the stock heads and intake and maybe put in the "hot cam". what compression shoudl i have if im going to supercharge? could my stock rods and crank handle all that? what kind of horse power and track times would i be looking at with each set up...? i dont want to run crazy boost numbers just like the 4.5 or maybe 6 lb system... anyone ever run the powerdyne system? thanks guys!

 

If you rebuild and install the Powerdyne you are probably wasting your money. I went with it only because my stock engine with 100K miles couldn't handle much more. You would be better to just get better heads and cam and skip the blower. If you want serious power go with one of the other sc units and you will be much happier. For the $3500 i spent you could buy a lot of extra goodies and make one hell of a nice engine.

 

So, what is it about the Powerdyne SC that you found so disappointing?
I have one that's got about 65000 miles on it, & I love it! (in the past year my car has smoked an '06 GTO- by three from 0-100mph, & runs in excess of 155mph!)
BTW- I am running 3.42 gears & (to date) the only suspension mods are the SFCs & the KYB 8-way rear shocks...
I thinkk that my stock '94Z convertible would prolly run high 13s or low 14s, so I wonder what might be going on with your setup?

The quality of the parts that came with the unit were junk. One guy complained years ago about holes in the tube between the maf and the blower unit and they never fixed the problems. I spent 2 extra days buying parts that didn't fit from the kit and i had to add washer and buy different sized bolts because they were wrong. I would call the instructions the worst ever and mine were missing 3 pages which sucked. My car only ran mid to high 14's before and i am probably down to mid 13's so it isn't bad. Once i get it running right it will be fine i just can't recommend the unit. I know i am not the only one. I read a buyers report and 8 of 10 were not satisified. Im glad yours is no problem and i hope mine goes forever.

 

Wow! Sorry to hear about that! I can only tell you my experience, which has been good. The only thing that I could complain about is that they don't use better bearings (mine has already been rebuilt, once- but it DOES have 60+K on it...)
Another thing that would be nice is if there was a way to intercool this unit, as the performance does go down as the temps go above 85*, though I know a guy who has the same probs with his Buick GN, & it is intercooled.
I did hear that in the last couple of years, the PowerDyne Co. started selling lower-quality stuff, & dropped the ball on customer-support, too. I guess that might be a part of your probs, if you recently bought yours...
So, have you heard of anyone 'cooling' a PowerDYne unit?

I have no idea if anyone has an inter cooled unit. I have had no problem since i finally got the few bugs out. I couldn't believe they sent bolts that could no way work. Its like someone ran out of bolts and they ran to the parts store and guessed the size.

 

It really depends on what you are looking to rebuild with and how much money you want to spend. You definatly want at least some form of low CR forged pistons, and I would go with some good head bolts and rods at bare minimum for a supercharged setup. Your crank should be good for quite a bit of power. Either way, if you plan on running a safe 15+ pounds of boost, I would spend a bit more on a stronger shortblock personally.

I personally am not a fan of the powerdyne unit. I have heard of more people with problems than people who are happy with them. Personally, ATI Procharger is the best IMO, and most guys are running them successfully on here. Contact Bob at EPP (www.exoticperformanceplus.com) and tell him CALL911 sent you, and he'll give you a killer deal on any Procharger you want. If you didn't want a Procharger, I would then say go with a Vortec, as they seem to be decent as well.

 

From reading the posts on here the only thing that happens from making more power is wanting more power. I would make ever effort to get the strongest bottom end so if you catch the bug you have the option to do it or not. I would recommend Procharger and Vortech but they do require a little knowledge to install.
