mustang supercharger

[1988montecarloss]

i found one of these supercharger kits for $500

what else would i need to put this on a stock 87 5.0?

or does everything you need come in the kit?

thanks for all the help ;)

Re: mustang supercharger

If the kit you are buying is complete as sold originally, then you should be good to go. But depending on how much power you're looking for, and how hard you intend to run the car, there are other considerations. A set of headers and freer flowing exhaust, and an upgraded radiator are items to think about. Some people go with much larger injectors like 42 #, and a custom tune, rather than the fuel pressure module that comes with the kit. Also, your 87 would be the speed-density EFI system if original, which generally doesn't like getting a bunch of mods without sacrificing some drivability ... but that can be converted later too if you decide to go with more stuff.

Re: mustang supercharger

i know this is off-topic but all of these should just bolt right in place, right?

and would this be all i needed for a whole exhaust?

Re: mustang supercharger

If you and the state you reside in are OK with no cats, then that set of parts should be fine. Otherwise, shorty headers like these are easier to fit with convertors:

You can make plenty of power with the shorty style, and they are a lot easier to install.

Re: mustang supercharger

The cats won't hurt you much for a street car. The STOCK cats are a mess but I'm running the MAC H-pipe and FMPP shorties and they setup seems to be fine. The blower kit is a good deal if it's complete and that's a nice set up - reliable power if you don't get greedy. Wish I had one.

Re: mustang supercharger

My brother has an 89 5.0 LX that he put a Vortex on. I can't comment on how hard it was because he installed it literally days before I got married and I had a ton of things to do and couldn't help.

What I can say from an observation point if this is on the low end of boost and they're telling you that 19# injectors will work : don't believe it! Even on the lowest boost setting you'll detonate and blow head gaskets like my brother did. He ended up putting GT40 heads and intake on when he replaced the head gaskets. He also upped the boost to about 10# IIRC. What a blast it was to drive like that ;D

Re: mustang supercharger

I'm running 24# on the 5.8 and was told that they would be OK for low levels of boost. I haven't gone there, however.

Re: mustang supercharger

I'd agree with that, 24 pounders should be fine if you decide to change them. FWIW back in the day when the Paxton kits first came out for the EFI 5.0 in the late 80s / early 90s I knew several people running them on stock engines with the original injectors. Once the F-150 Lightning 42# injectors became available for a reasonable price, and more people were doing custom EEC tuning, some started ditching the FMU on the Paxton and Vortech kits and going with the big sprayers instead.

Re: mustang supercharger

will a stock fuel pump be enough for bigger injectors??

Re: mustang supercharger

danger danger , burned pistons around the corner

I believe he's using 24# injectors

Upgrade fuel pump would be a good idea too, they are cheap enough for the Mustangs these days. You can get a decent Walbro pump for around $100 ... www.autoperformanceengineering.com ... genuine Walbro, not the Chinese copies on eBay for $60.

Re: mustang supercharger

so ive run across some edelbrock performer heads with a "stage 2" port job? and billet stud mount roller rockers for cheap. ;D

what would make more power? the 302 with the heads and a cam?

or with a supercharger on 7-8 psi with a cam?

also, what cam should i go with? i was thinking the e303
http://www.latemodelrestoration.com/item/M6250E303

...and what can these motors rev too?

[fast Ed]

Re: mustang supercharger

Blower at 8 psi without the cam would likely make more power than heads and cam together. My vote would be for the blower, upgraded injectors and a tune, exhaust, and maybe an MSD 6 BTM or similar ignition box.

The 5.0L HO EFI has a factory 6,250 rpm fuel shutoff in the PCM ... but the small heads and intake are all done by 5,000 anyway. Engine itself can take 6,500ish.
