Ingredients for supercharging!

[fivemustangs]

Hey guys, I have a few questions for all the pro's out there that know about supercharging. I have looked through stangnet but couldnt find a compleat list of ingredents to supercharge my 95 GT. I want to know how you did it and how your results came out. my set up so far is, trick flow stang 1 cam, trickflow intake, 30lb injectors, 75mm mass air, aluminum pulleys, 75mm throttle body, forged rods and pistons, fuel rail kit with braided lines and fuel pressure reg., long tube headers, off road X-pipe wit 40 series 2.5 all the way back. and 5 speed conversion. Just need to know if there is anything that I missed or let me know how you did it differently. :SNSign:

You might need a bigger fuel pump, possibly move up to 42# injectors depending on how much boost you are going to be running. Does the car still have the stock heads?

 

[FlyBy763]

As said before...youll need injectors and a fuel pump. Are you wanting to use a centrifugal blower or a Kenne Bell? Either way you should be able to hit low 400s HP with a blower.

 

[fivemustangs]

This is very true I should invest in a better fuel pump. The heads are GT40s with stronger springs so pretty much stock, Im going for the daily driver theme with some kicka$$ horsepower incase I need it. im not looking for full potencial so im hoping that the 30lb'ers will work for now. I was also wondering about fuel rails, all I can find for a fuel rail kit is 87-93 mustang's, will these kits work on my 95 5.0? I heard it wont clear the distributor, has anyone tryed it? also I bought a 76mm mass air not 73mm do you know how much HP that is capable of handling?
Thanks guys!

 

[FlyBy763]

Why do you want fuel rails? Wont help you any besides looks...Stock ones are good for quite a bit of power

 

[Venom351R]

Those fuel rail kits are expensive $500+. You would be better off putting that money towards the tune on the car after its boosted then dumping into something you dont really need.

 

[revhead347]

+1, I'm still running stock fuel rails.

For what you say you wanna do ........

Yes ... The OEM rails are more than adequate

Now ... About those tiny 30# inj's

They just ain't gonna cut it
unless
You work em with elevated pressure

They make a device for that called a FMU

While it works .......

My first recommendation would be to step up to 42's and a custom tune

A thought about using a blower to make power on a d d

All that h/c/i stuff is nowhere near as important like if you were NA

You might wanna rethink that TFS cam as it has a fairly good lope to it

Ok so cancel the fuel rails, do you have a good guess what they are rated at? also do you know if the 30lb will work with the set up until I buy the supercharger? and does anyone have pictures of there supercharged set up on there sn95? so I can see how hard it is to do the installation.

I tired the whole FMU thing, it was a nightmare trying to dial in my A/F ratio, it just wouldn't go where I wanted it to, I disconnected the FMU and tuned in my 24lb injectors to the desired A/F ratio pretty easily but they were then running at 115% duty cycle, lol not good. 42lb injectors and haven't had a problem since.

My previous Mustang was boosted. 95 GT w/ a Paxton Novi 2000 w/ about 10PSI. Your set up + boost would be making more then what I was b/c I had stock heads and stock cam. I was running 30# injectors and it was still going lean up top. I had to use #42's on a very mild boosted set up. FMU's are band aids for a lack of fuel issue. Your much better off going to the proper size injector then relying on FMU

 

[99FiveOh]

Do yourself a favor and just skip over the FMU thing, I tried it as well and got nowhere. I used a high pressure 255 pump and 42's on mine with an 80mm Pro M MAF and my car ran like a dream, but only after a tune! I ran a Vortech V1 S trim pushing 13 PSI and made 424 HP to the wheels with equal torque.

Here's a pic of my old setup:

 

[1fast95stang]

I have a procharger d1sc running about 14psi of boost, lots of things i learned. I have a custom tune on my 95 stang had about the same, some minor heads cam intake. Went with 42 lb injectors. Got it all installed and went to fire it up and the old tune was set for 24lb injectors and the car wouldnt start. With the new injectors the car would flood instantly. You need a bigger injectors, go with 42s and atleast a 255lph fuel pump. Dont go with a boost a pump. And also dont go with a FMU. You have to remember if your looking for lets say 450 horse power you have to remeber that if your making 14psi you dont really make alot of boost untill you hit high rpms. In my car at about 4900 the boost really kicks in a the car pulls hard for about 1.5 seconds then i have to shift, then it drops to low rpms. and im only making about 4-7 psi of boost. So you think you have 450 horse power, but you only have that for half a second at redline. With the 95 and the procharger i had many problems with backpressure. I blew the dipstick back out of the oil pan and also blew out the rear main seal. The procharger kit makes you have to add a breather cap to the oil fill to take care of the problem but something they didnt tell me untill i called with the problem. Also when buying a bolt on kit you have to remeber that the kit is made for a stock car. i had a modifed hood, wouldnt fit. had my motor pulled to have it bored, and when its put back together things dont go exactly where they are suppose to go and thats a problem. When installing its not just putting it in. Lots of fabing making things fit. Get an intercooled kit, if your going to spend that much money already do it right. and always go big. You might not use all the boost it can make but maybe 5 years down the road you want to build it bigger you would hate to have to buy a new kit. With my D1sc i can go up to 24 psi just change the pulley. Do YOUR RESEARCH there is alot you can learn from people like me who have already done this.

 

[99FiveOh]

Yes, I almost forgot about the dipstick blowing out! Even a breather filter didn't cure the problem completely for me, but I had a high mileage motor and some of that was blow by. I can't remember exactly when my car would start making good boost, but I can tell you it was a blast to drive all the time, wheather at high RPM's or street light to street light runs.

I can also say that I had ZERO problems running my S trim without any way to cool the air charge on it, kudo's to Tony at HP-Performance in Orange Park, FL. Also, the fit and finish of the Vortech kit was second to none, everything bolted right up exactly as they said it would. The hole in the oil pan wasn't near as bad as people make it out to be, the worse part was finding the damn drift punch big enough to get the job done, Harbor Freight Tools to the rescue! And don't listen to any of the rehtoric about Centrifical s/c's not making power down low, I could never keep my tires planted off the line and it's amazing how fast the boost does come on once you do hook up!

Figured I'd post this dyno sheet up since people like to reference them, and to give a good plug for the tuner since they did a phenomenal job with my car!

 

[ProKiller]

with what you got, you can install a supercharger but like everyone else said, you'd be better off getting 42# injectors and an 80mm Pro-M. C&L mass airs don't always agree with our computers. a 255lph fuel pump and a boost-a-pump will be perfectly fine for now. That setup with 42s will get you up to the 500rwhp range.

i've had my vortech for like 5 years now. only problems i've had have been with the engine not the supercharger. kept blowing head gaskets with the stock 302. switched to the 331 w/ cometic gaskets and haven't had a problem.

you don't NEED an intercooler but its not a bad thing to have. vortechs are cheaper than prochargers, so if money is an issure, i'd go with the vortech.

YOU WILL NEED A TUNE! don't even think for a second you can just install it and drive it. you will need a tune to make sure it runs efficiently.

old setup w/ 302 and completely factory vortech install:

current setup w/ 331:

I have almost 600 hp going through my stock rails, and I have never had a flow issue. That's also at 95 psi due to the dry nitrous kit. I imagine you can even go higher than that. The 30lbs will work until you get the supercharger, as long as you have a mass air meter calibrated for 30 lbers.

All this is VERY helpful, I think I am going to have to go with the 42 pounders, and I have been reading a lot about ford lighning 90mm mass air meters, has anyone installed one of thoughs? and tell me how much of a challenge that is, I know I need to get everything tuned in the end, I live in maine and luckly 1 out of like 3 dyno's in this state is only half hour away! I also wanted to address about the stock block and crank I have in engine, could this handle the boost up to 500HP on a stock block? also about the supercharger, should I get a internal lubed charger or one with oil lines? and if so do I need a bigger oil pan? and one last thing the stock t5 I have is a world class but can that also take the power? I will eventally be upgrading but until then........

 

[99FiveOh]

The stock block and T5 will handle the power just fine, IF you respect it and have one hell of a tune on it! It's important to stay conservative when using stock parts. A reliable 350 rwhp car is better than a fragile 500 rwhp car. My car was rock solid with the power I was making because of the tune. I really couldn't go wrong because the tune wouldn't let me. (as long as I monitored the essential systems and kept good fuel in it!)

Now as far as self contained or engine oil lubricated systems, it's entirely up to you. I liked the engine oiled Vortech system because I didn't have to worry about changing the oil in my charger all the time like you do with the self contained units such as the Prochargers. You change the supercharger oil every time you change your engine oil.

 

[fivemustangs]

Ya I was pushing for around 400WHP at the max a little less would be fine with me. Now every reply someone says something about the proper tuning, can you tell me a little more about that, when I take it to the dyno will they have everything to tune it? Do I need to get an electronic tuner for my car? Iv looked around and they are hard to come buy, does anyone know some decent brands that wont kill my wallet for 94 95 stang? and does anyone know what they tune at the dyno?

 

[ProKiller]

its your decision as to whether you'll want to be able to tune/tweak it yourself or have a shop do it. most shops will burn you a chip for the computer with the proper timing and fuel curves.

if your self tuning there's the AFM PMS, Tweecer, AEM, etc.
