That's a test rig designed to push Eaton blower seals and Ford intake gaskets to the point of failure, correct?

Looks good. :)

Well, sort of. We'll see what breaks first. I'm surprised there's no interference between the exhaust pipe and jack shaft bracket. 57584

Todd, aka Roadhawg, was going to do a compound boost deal on his sc powered '95 Mustang. He's now undecided on whether to do it or go big block ........:eek:

Where are you planning to route the down pipe ? How is the clearance from the radiator and main cooling fan ?

Not sure about the down pipe yet, not sure which way ill have the turbo face. The way the turbo is in the last pic makes the discharge pipe a straight shot to the throttle body, the compressor being in front of the jack shaft would require a few bends to make it to the throttle body. Radiator fan clearance is fine with the turbo facing either direction. About 2" of room with this turbo kit installed on yhe last motor in this car. The downpipe will be 3" from turbine to the rear bumper. Should make for a quiet ride. Also adding a 3" electric exhaust cutout for when WOT.

Is that a 4.3l? What turbo?

It's a 3.8l. 01+ block, SC crank and finally got the 4 bolt main caps fitted after a year. Turbo is a cheap master power t76 with a small 60-something millimeter turbine wheel. got it for 200 bucks. It maxes out at 800lb/hr and I'm looking for more than that. But it should be fine for getting the setup operational...I hope.

65mm p-trim probably. I'd step up to a q trim turbo with the blower to prevent as much back pressure as possible, after you get it going.

57747 today I ordered two 12" pieces of 11/16 blank fuel rail, a magnafuel -8 regulator and a magnafuel -8 inline filter and motorcraft 160lb injectors from a grand marquis propane injected 4.6l. Edit.. It only shows one picture, I have two more to upload.

57749 that's all I've got for now. Still in the process of test fitting everything. Like I said, I'm surprised not much needed to be modified. Just a notch needed to be cut on the jack shaft bracket. Ps pump has the regular return port blocked off and a NPT 90 degree barbed fitting screwed into the back of the pump reservoir

Whar are you using for a MAF on your compound setup(blow thru)? How much boost from your blower and how much from the turbo? Going to be an awesome ride! Also how much total boost are you shooting for?

No more maf. Megasquirt uses map instead of maf. Planning on running 10psi from the m90 and an additional 14psi from the turbo so hopefully 24psi total, and bump up to 30psi combined if needed. Will be using a large air to air intercooler and meth injection to keep the intake temps under control.

You are going to have crazy boost. In a compound setup it is not added so you will have a ton of boost.

If you have 10 from the blower it will follow

10 plus 5 from turbo = 18.4
10 plus 9 from turbo = 23.4 ( your target boost level )
10 plus 12 from turbo equals 33.8

There is no chart for 10 and 14:eek:

With 10 from the SC your engine is about the size of a na 350ci. The trick is having a turbo that is only boosted to 9lbs of boost but will flow enough to supply the motor with all of the needed air if that makes sense.

Compound boost charts are easy to find.

Can't wait to see her running!:D

I hope this helps before you set your turbo to high and blow that motor.

Thanks for that info. I was not aware about more boost from less turbo boost but after thinking about it I suppose it makes sense. Like a bigger throttle body creates more boost by allowing the blower to breathe without a pulley change. I was going to start low and see what happens, then crank it up. I threw out 24psi as an arbitrary number, but the plan was to ultimately get up to 30lbs. No reason why, really. 30 just seems like a high number and maybe produce a high horsepower number too, hopefully. Lol

I have always thought a compound boost setup would be awsome so I have done a lot of research on it. You have a good plan. Start low, 5lbs from turbo and keep turning up the wick!:D

I have also done a lot of research on doing a compound setup (turbo feeding supercharger) and I'm looking forward to seeing how this project turns out. I agree that the best approach will be to supply the supercharger inlet with a relatively low amount of boost (4-5 psi), mainly to avoid having to cool the air charge prior to reaching the supercharger.

Through the years that I'm been thinking and planning this I decided that I will have a air to liquid intercooler between the turbo and blower to help control that heat.

Should I spray meth before the supercharger or should I mount the nozzle in the return plenum? Will spraying meth before the m90 cause issues with rapidly cooling the rotors/case?

aside from that, I have not touched my car all week. I did get an android s4 active and you guys should see this msdroid app. Its crazy how much you can do with the phone and megasquirt. Ill be using my phone to communicate with the ms3 to tune/datalog instead of my 17" 30lb ancient laptop. Makes things very convenient.

There is a thread that discusses this exact topic. I believe that best advice with to put it after the blower but I can't remember if it should go before or after the IAT sensor.

Depends on if you have coated rotors or not. If you have 94/95 rotors it will strip the coating and if you put it in the return plenum you want it as close to the ACT as possible. I wish they had an android binary editor app so I wouldn't have to lug around my laptop :cool:

Interested to see how this works out.

Not to be too much of a buzzkill but in the end the result is usually the compound system is very complex for adequate results. With a proper turbo setup you can reduce complexity considerably and have more torques through the rev range.

Hope you prove me wrong though, and props for trying.

In a mid mount setup with a oiless turbo it would be really simple when you are using the stock SC setup. Thats how I would set one up and one day will. I agree major props for trying and I can't wait to see the result.

By no means am I saying sompound is better, SC is better or turbo is better or this will be easy. My concern has always been the tune and having the properly sized turbo for the setup.

On a five speed, SC whine, turbo whine and a blowoff valve sound thrown into the mix would be an amazing sounding car!:D
