I did the install today, E-bay didn't pay off. I have a universal bypass valve. The activation line on top of it, where does it go?
Where do I get the disc for thr FMU? What one needs to be in there with a 9# and 30lb injectors? Should the pully on the charger have a little slack it? If I rock it back and forth? Thank guys, I wanted heads buy I'll settle for what I have.

mike72678 · 02-24-2003, 01:35 AM

Be more detailed with your bypass valve questions and I will be able to help you out , it does not matter if it is universal as long as it is functionining properly , however , it may require a custom install . As for the fmu , throw it in the woods as far as you can and forget about it , I have heard too many storys about people not being able to get their boosted stang tuned right because of it , they are good for stock applications only , get a properly calibrated mass air meter or custom burned chip with a boost sensitive fuel regulator (accufab,aeromotive) for your set up and you will be much happier. And last , no , you should not have a noticeable amount of play in the supercharger pulley.

Belt Slack

No Belt Slack Is a Major problem In gaining consistent Times All Belt should exceded Ford Spec Yes you will waste allot of Belts But you want ET and Whole Shot? I have an 11 Psi procharger.
Also are you using Underdrive Pulleys?

30lbs Injectors are a Good Question but its a Relitave Question are you at sea level? Mountain? Desert? Pump Gas? Av Gas? Chat with your Favorite Wrench You Must have a Guru SVT tech maybe?

I agree about ditching the FMU. You don't need it. Throw it away, far far away. If you're running underdrive pulleys, toss them as well. You can't run underdrives with a blower...the pulleys will spin the blower slower which (I'm pretty sure) isn't what you want

. You should be ok with the 30# injectors and a 255 lph fuel pump. Just set the timing at 10* and FP to 40-42 psi as a baseline and tune it from there.

A dynotune and custom chip would be a good idea in the future.

On all But my Blower The Procharger I have Under Drive Pulleys According to the Following.

In Hawaii Bellow Sea level The Air is so thick that Less Drag from the rest of my Components Under driven Pulleys are better at sea Level Its ratioed

I dont really Understand All of the Underdrive and Overdriven Pulley techniques But the are serious and My SVT GOD

Knows allot about setting up an engine. And It can Change From one hour to the next . Also The Crank Belt that Drives the Blower Is always the same size My sub conponants that are belt Fed May be under driven or Overdriven according to a Ratio.

88workcar · 02-24-2003, 10:02 PM

I am not using underdrives, I am not ditching the FMU, I am not switching to mass air. I put the belt on today and just blew air out the side of the car, that is overwhelming!

On the bypass valve their is a port to put a line on. Is it a vacume or a boost line that goes there? And where do I put the other end? What disc should be in the FMU with a 9psi charger and 30lb injectors?

I want these questions ansewered, not what else I should do instead. Thanks.

mike72678 · 02-24-2003, 11:11 PM

you put a vaccum line to that port on the bypass valve , the vaccum will hold the bypass valve open and when the vaccum turns to boost , the boost pressure will in turn close the bypass valve so the air can no longer recirculate . If you want to know that info about the fmu , you are going to have to call the manufacturer , however they will probably reccomend not to use the fmu as well .

mike72678 · 02-24-2003, 11:14 PM

I forgot to mention , you can just splice a t-fitting int o one of the decent size vaccum line that go to the intake and run a line from that to the bypass valve . And , what are you talking about the air blowing outside the car ?

88workcar · 02-25-2003, 06:42 AM

Thank you mike, we just was interested to see how much air flow come out of the blower, It is bolted in the car but not tied in yet. So I put the belt on the blower and put the 90* pipe facing to the side and cranked the car, simply pumping air strait to atmospere.

Hozer 88GTConv · 02-25-2003, 09:26 AM

MM&FF had an article a few months back where they were tuning a blower combo and they too had to contact the FMU manufacturer for the correct disc. I wish I could be more precise for you, I feel your pain.

I understand your refusal to consider the chip option, however I must agree with some of the guys above that it is a good one.

Good luck...

88workcar · 02-26-2003, 06:40 AM

Thanks Hozer, It is a 6-1 disc that I need. Yes to all of you, There are better ways to do this. I am just starting out, the finance dept is closed for a while. I will be going with a TwECCer RT, that will come later. If a FMU was part of the kit it will be fine for me to start with. Do I need a BTM? Will the RT do away with the BTM?
