well took the truck to the mustang dyno. hooked up the map sensor, needless to say we are pushing 24 psi w/ the big pulley and 28psi on the smaller pulley. i only had 110 oct in it so we were kinda scared to push it until we got some c16 in it.
the pulley swap is good for about 60 hp though so its going to be close to 800hp all said and done on just the blower.

I'm expecting a good "I told you so" to all of those who have argued a centrifugal can't push a heavy truck down the road.

We have a gen 1 here in AZ running 10.8s with one. Does that count.

Nope. You can buy the GMS COP's from LFP for like $100 less than RPM.
I too am running the GMS COP's and have been for several months now. Making over 600 RWHP on the dyno with no issues.

JDM should be selling these. Most of the bigger better Ford Performance shops do. Only Granatelli has teh patented design with 60,000 volt outputs

HI!... Granatelli : Well heres a question for you then. Why is it, that after I install your GRANATELLI cops on my F-15O's 5.4, 2-VALVE that it caused the truck to stall all the time? I re-installed the stock cops and the truck runs perfect. Some guys on other boards that have had similiar problems say I need to install a MSD capactor somewhere due to electrical interfference from your 60,000 volt coils. I have the MSD capacitor, where do I splice it in at????? I spent $500 for these GRANATELLI cops and can't use them.

I have a buddy running the granetelli's with no problems but I have also heard two of the top tuners say they really dont do much over stock, and simply putting in fresh stock cops have a similar effect.
most of the stock cops replaced with the GMS ones are stock cops with lots of miles, I'd like to see the difference between GMS cops and some factory fresh FORD cops......not trying to start a flame war I just havent heard of anyone swapping brand new factory units with the GMS ones, or Accel for that matter.....I'm at 70,000 miles on the stock cops and they are running fine but the idle is gettign a little rough so I will be replacing them soon, but most likley for more stock cops.
