Supercharger Install

[ak1234]

Does any one know if to install a Paxton Style Supercharger on Ak1234 is there a kit.  Meaning I could purchase one but which kit would I buy ?  Mustang ?  I was thinking maybe the factory used one of the off the shelf kits on the SUPER BLOWERS.
   
   Any help would be greatly appreciated.

Ron, you might try John Owen @ malta, they did a few and might give you direct and even know what changes they did between MKIV and SuperBlowers. Other than than that a Mustang kit <do you have speed density or mass air flow or carb> without AC..still be a bit of custom I believe. Jim

[ak1234]

Good idea .. I will try John @ AC.  I have an 88 HO 5.0L with EFI I believe that Mass Airflow ?  I'm thinking a 88 Mustnag kit should do it ..but I think last time a long time ago it requires an upgrade to the fuel system and the car should be sent to a TUNER to set it up after installed ?
   
   Thanks.

I have fitted a Powerdyne silent drive supercharger to the 302 in my MK IV that runs at 6 psi. Up to 9psi is available
   http://www.powerdyne.com/
   I believe it is the same type that was fitted to the superblowers.
   Took experts to get it to run properly and complete the modifications to the EFI etc. Now that it does run properly the dyno indicates 450 bhp.[:)]

Ron, might be mass airflow, might be speed density...the engine installs did not follow the serial sequence, year of mfg or perhaps the serials followed no sequence necessarily. If you have mass airfow, you are ahead. I'm told the speed density has a narrow window of improvement and has to get replaced for upper ranges. The other option is a positive displacement unit aka kenne bell, which yields better boost down low.Jim

JIm / Ak1440 .. yes powerdyne was the manufacturer ...I'm told the fuel system had to be tweeked or upgraded also and tuned for final peek perfromance.
   
   MAF or MAP not sure how to tell the difference ..is the MAF in line on the air intake ?  I looked for a pic so I can look at the motor tomorrow but nothing cearly shows the difference ?

Ron, I don't know how to tell visually. there a FORD performance site that might help. But, BA bought motors in somewhat large lots as consumed them slowly, so it is possible you have a speed density. Check the actual build date in the registry under the OWNERS club. Jim

Does anyone have any pics of the motors in SUPERBLOWERS with Supercharger units in place ?

   I will wilingly send you some photos of my Superblower set up as cars did vary from one model to another.
   
   The car in the photo may be ACSB 7005, which would make it a 1998 model. Mine is 7013 (Oct 1999) and there were problems with the supercharger set up. This was solved eventually, but not by the factory( I wrote an account in ACtion a few years back) and the car does now give out a genuine 355bhp but a number of mods were required to get in going 'on song'.
   
   Send me your e-mail and I will send some photos and an account of the work done to the car if that would be of help.

Ok couple things
   
   The SUper Blowers were supplied by Ford MotorSport.
   
   Also the Super blower cars had head gasket issues at 6psi boost and definately at 9 psi boost.
   
   Power dyne tells me the kit will require upgraded fuel system and other tuning items.
   
   AK 1440 that blower set up was by AC ?  The EFI unit I have never seen here in the USA and the blower has an intercooler which I also have never seen on a SUpercharger .. turbo maybe.
   
   Ian Rogers ..thanks I thinkw e are on the same page ... my info came right from the source ... and would love pics of a Factory supercharger.  ronmarl@optonline.net
   
   Thanks to ALl for your help

   I should have read your post more thoroughly. The supercharger piccies are of AK1440 an ex US supplied 1993 MK IV with a 302 efi  crate engine from the US. So it is not a SuperBlower as such.
   I had the powerdyne supercharger fitted in the UK which was not an easy installation. The replacement crate engine was highly modified and the initial detonation problems were solved by the intercooler. The engine also needed a very much upgraded fuel system. In fact it cost a small fortune to get it set up properly. Not sure if it was worth all the hastle it in the end. However, it really flies.....

Jbottini mentioned Kenny Bell – IMO an excellent alternative. Twin screw positive displacement 'chargers produce substantially more power from zero revs right up the range, whereas a centrifugal blower only starts to work above about 4,000 rpm - useful if your rev limit is 6,500 – 7,000, but the 5.0L is a relatively low revving engine and needs major mods to hold it together much above 5,300. Either way, full potential won't be achieved unless aftermarket heads are fitted (the exhaust ports are very restrictive on stock heads) together with free flowing inlet manifold. Also, when swapping heads replace head bolts with studs to avoid gasket failure.
   
   I believe the Kenny Bell kit includes bigger injectors and a second pump to cope with fuel demand, and a programmable chip for the ecu plus all the other bit required.
   
   An alternative using a twin screw is to go down the do-it-yourself route and obtain a second-hand Eaton, as used by Jaguar on the XJR – not quite as efficient as a Kenny Bell – but a lot cheaper. (I just happen to have one I might sell!) Get a tweecer to re-programme the ecu to avoid expensive dyno retune and you're in business!!!
   
   I had intended supercharging my Brooklands Ace, but in the end was forced to conclude there wasn't enough clearance under the bonnet - damned stiffener in the way.[:(!][:(!]

Max,
   
   Yes all of these suggestions basically one is better then the other.  My original intention was to keep the motor basically stock .. for driveabilty and originality.  But I see thats not really possible.  With a Centrifical Supercharger its going to take pulling the motor and upgrading it signifcantly along with all the upgrades that always go along with it.  My choice would be 9psi boost.
   
   I guess its killing me to cut up a 9000 mile car ..so I think I;m going to stick to my Pantera project.
   
   Thanks All Ron
