Has anyone had any experience with a Vortech s trim on a 86 5.0 efi? good or bad ? My friend has an S-trim sitting around he just went to a 427 turbo engine in his mustang, He was saying if i put the money into the parts to mount it he would throw it on what you guys think?

Do you even have a h.o. motor?

The heads and cam will be quite restrictive for a centrefugal supercharger imho.

I wouldn't be against buying it and waiting until you can use it though. I'd at least do a quick h.o. swap and intake/exhayst just so that you can get a good bit out of it. You'll want a good fuel pump, larger injectors and maf/chip before you could really use it.

In my experience, there is no "throwing on" of a supercharger.

The cost of the head unit & brackets is a fraction of what it takes to bring the supporting systems up to snuff!

I had a Powerdyne supercharger on my stock engine for a few years before i went turbo. I made the brackets myself from some s metal and a chevy truck belt tensioner. It's definitely worth doing. Made way more power. The car ran 14 flat in the quarter on that setup.

I'd be worried about fuel...

I doubt the stock computer could compensate for it. 19lb injectors are almost maxed on a stock h.o. and they are on a mild setup. I doubt the 14#ers would have much over stock.

I have always wondered what a blower would be like on the s.o. cam though.

Blowers are not the hot setup. Turbo cars are where it is at. It takes HP to run a BLOWER. The new Vette uses 120HP to drive the blower. Turbo cars always make more HP than a blower. But and i know this will cause a BUZZ. Ford engines will not respond the way you would think with a blower. The heads are to small and they flow rather bad. Ok now you can POUND ME!!

NOTE a 21 LB injector at 43 With a 80% can sustain 260-270 HP Give or take a little. Not to many 302 engines that are over injected with 19 LB injectors Just saying!!

I do agree a boosted 302 would need bigger injectors than 19. Like 24 would be a ball park. As stacks points out a 19 is way to small for a big HP 302

My boss's stang only dyno's 260hp at the wheels with a blower and 19# injectors. He isn't limited by air...

I agree with you tom. But I think i'd go blower over a turbo, just personal preferance. I've always dreamed of a kennebell sitting ontop of a lil 302.

I had a wide band monitor on mine and it maintained stock air fuel (14.6) with no modifications to the fuel system right up to about 8 PSI on the charger. Although stock AFR is not considered ideal on boosted cars, it doesn't pose any threat to a motor with a compression ratio of 8.9:1. I know this because I performed a compression test on the motor after 3 years of abuse from the supercharger and it still had healthy even compression. When I first switched to turbo it would run lean as boost went higher. To remedy this, I swapped out the 14 pound injectors for 19s, dropped base fuel pressure, added an FMU, and a walbro 255. This was something I kind of rigged up with parts I had lying around to get the car on the road the night I finished the turbo install, but it runs so good I haven't had to mess with it since. Wanna see an 88 Thunderbird with no engine work and a $500 pieced together turbo kit spank a bolt-on LS1 Camaro? Check out my YouTube channel. http://www.youtube.com/watch?v=KKznNBTTzcEThis was on only 7psi.
You'd be surprised what you can do with very little. This car still stands up to a two hour round trip commute to work every day and endures 8 hour track days. The proof is in the pudding.
You'll be fine on low boost and you'll make tons of power for cheap!

I agree with you on that. Nothing impressed the car show guys more than a 671 sticking through the hood. Just an awsum feeling. But hands down a TURBO makes much more HP. Thanks

Very true. That's why I switched. Turbo has less parasitic losses and also allows you to run as much or little boost as you want with the turn of a . On the other hand, if someone was giving me a supercharger and offering to help install... that's a no brainer. You won't be dissapointed!
