I just bought a stock `88 LX 5.0,AOD.I might keep this one for a while and want to do a couple mos,one being either 3.55 or 3.73`s,shift kit,and a K&N.Another being a blower if I can save up enough for one.I was thinking of a Powerdyne one,the 5 or 6psi one.What else would I have have to do to safely run it on the car? I`m told I really don`t have to change anything as its the basic kit.Also what kinda HP could I gain with this mod on a stock or almost stock motor?

Don't fear the gear! 4.10's for an automatic!! Along with a higher stall converter.Stewart

i my self own a 9psi powerdyne kit... just go with the 9# and 3.73's (frame ties and slicks are a must with that set up) you should be around 325-385hp depending on how u set it up. and the 6# kit aint werth the money. you wont get any real boost till just b4 the red line.. i run 24# injectors and a 255lph fuel pump but as far as i here the stock 19#er's should do the trick as long as the rest of it (sept pump) are stock.

Since your 5.0 is a non-California '88 you are going to have to convert from speed density to mass air before supercharging. Unless you are desiring a super easy install (no oil line to plumb) and super quite operation I would suggest going with a Vortech a-trim (~$1800, s-trim if you have more money). Too many people have had problems with Powerdynes (yes, I know some people have had good luck and results) plus there are guys with a-trims that run 10s (pullied different with engine mods of course)!  As for gears, the dominant opinion is at least 3.73s (as you can see I am going 4.10s :>).------------------

Tim is right. Unless you convert to mass air, forget the blower. Also, a second "yea" for a Vortech. I've heard no high praise for the Powerdyne unit. If I blow my 93, it'll be a Vortech A-trim. You can run an "A" with no major engine mods. Any more than 6 psi and you will eventually blow your head gaskets without some "improvements" being done to your engine.------------------

I really don`t have alot of money to spend.I like the Powerdyne because it`s quiet and no oil lines to run.And the 6psi one is alot cheaper,and I don`t want to hurt the motor too much right now.Frame ties are something I had already planned to do anyways.I plan on driving this car alot with the occasional stop-light or 1/4 mile run so I`m leaning towards the 3.73`s instead of the 4.10`s,I had them in my `89 LX 5spd and they weren`t too good on gas.

I recommend the Powerdyne. I installed a 6 psi version on my '88 LX sedan last year.
as mentioned, you will have to convert over from speed density. That will cost a few bucks. Also, I highly recommend having your cylinder heads worked on prior to installation even with the 6 psi model. I brew my head gasket almost immediately after installing the blower. I had to pay to have the blower removed and reinstalled. My main reason for the 6psi model vs the 9 psi was to avoid possible damage to the drivetrain. I just wanted something to give me a little more kick when cruising around. I installed a 3.55 rear on by 5 speed. I would not go w/ anything lower as your rpm's go way up cruising at highway speeds and you wouldn't even need 1st gear.(maybe an automatic has different gear ratio than manual)

Hey Steelman, welcome to M&M. If you get a chance, drop by Sam's Place and introduce yourself. Sam's is our lounge where we hang out and relax.As for the Powerdyne, like Dave said, I haven't heard anything good about them. That is, until I read your post. I won't knock them, because I don't have first hand knowledge. But when it comes time for me to plop down my chunk of change, based on what I've read over these past few years, Vortech and Paxton are the safer bets. quote:

DON'T FEAR THE GEAR! I used to think the same way, that the RPM's would be too high for regular freeway use. But I was convinced, after reading a lot of first-hand experiences, that 3.73's in the rear diff of my 5 speed GT would be okay for freeway driving. Heck, I'm even considering 4.10's now!!  I'll be turning less than 3 grand in 5th at 70mph, and lets face it...while MPG is important, it's not one of the first concerns when we start up our beloved Mustangs!!

With the AOD the highest you should bother going is 3.73s which would be a great compromise. Even with 4.10s with the OD you would be looking at 36-3800@ 90 mph (4500 without).------------------
