I have been thinking of converting my 9# boost (only driven on Sundays to the gas station and back ) Powerdyne supercharger over to a Vortech.

Any one have an idea of what would be needed? It looks like the brackets are interchangable(?)

I already have all the needed upgrades, fuel, ignition, etc. I think all I need to do is replace the supercharger head, add a oil line, and fire it up??

Worth changing or not worth the bother??

And some depends when you bolt an S-Trim in place of the Powerdyne.

Been there...amazed myself.

I went from powerdyne to an SQ trim. Glad I did, traded some bottom end but gained upper rpm power. This may be in part to the SQ with stock pully will deliever atleast 11 if not 12 pounds on your setup. the bottom main support bracket is the same as the powerdyne and you can leave it if you have modded the bottom like I did to mount the atl in the smog pump location. the top plates are different and will bolt right up the the main support with no mods. The belt tensioners are very different and may require you to change to alt/waterpump etc belt out of the way depending on your current routing.

If you have any questions or need pics shoot me an email, be glad to help you out.

If you are going bigger get the powerdyne gear driven unit, it will make 18psi, and you can keep your brackets, it's just a head unit swap.

It would be easier and cheaper, and this unit will make the hp as a vortech.

Actually you can look at the october 2002 edition of Fast fords & MM they took a 302 with afr heads and made 594 hp with only 9.9lbs of boost.

They did a r-trim which made 638hp with 13.8 lbs of boost.

Adding about 10-12hp per lb of boost you are looking at the same hp as the vortech R-Trim.

So go with the powerdyne, and if it works let me know and I will switch to the XB1A too.

Does the gear driven Powerdyne give you some boost level options. I assume it's not always 18 pounds? Pulley size change or ???

Also:

Ozona -- please expand on your thoughts. Would like to hear more about your experience...

Thanks.

I am not positive but I know they have a 13lb pulley and a 15lb, but I bet they have few choices with this new guy.
