Originally posted by wozzoom I would think that the ACV bolts on the lower intake manifold would make a great mount for a bracket...assuming of course that you removed the ACV. the air-pump mount is a little to far forward to use as a primary support, plus the aluminum waterpump casting there is prone to breaking. that leaves the intake itself and the engine mount. |
Originally posted by wozzoom New question: Vacuum Source The Fuel Pressure Regulator requires vacuum to operate. Since the intake manifold is now pressurized under boost, the FPR will no longer function. Correct? Should the vac source for the FPR be re-routed? Where to? Before the SC? Next Question: Relief Valve Would the stock TII relief (blowoff) valve be enough for this setup? However the vacuum line to the FPR must be the same vacuum as seen at the injector tips. (after the throttle - same as stock) ed |
Above poster is correct, all the vacume line going to the FPR is doing is to equalise the pressure in the fuel rail and the intake manifold so as to achieve close to the same effective fuel pressure.
Ie, fuel rail at 0 vacume is at 40psi under idle loads/vacume it would be ~30psi, under boost it'd be ~50psi.. The stock one rises linearly, 1psi of extra fuel rail pressure per pound of boost in the intake manifold (similarly under vacume aswell, but the opposite, obviously.. :) ) (plucked some numbers outa my arse there since I don't even know the base fuel rail pressure.) |
hey guys sorry i havnt been on no access.
during vacation i made a new idler bracket, got my new idler on, and painted all pullies and baked them at 300 degrees. The reason the car boged in the vid is because it was ice cold, it had sat at school all day. I shot the vid between classes and only had three mins. I didnt let it warm up at all. that is why there is a little smoke in the vid also. here is something else very interesting you should all know also. Before i had my s/c on, at any shifts above 6500rpm i had a nice puff of blue smoke out the back, (worn oil control rings) but now with the s/c i dont have any noticable smoke at all! even at redline shifts. why is this, is it because the boost in the combustion chamber doesnt let the oil in or what, I dont know why but i know i like it Here are some pics of my progress. The pics are shity , but it looks very nice in person. Also, soon i am going to shoot a vid from outside of a run and also one in the inside so you can see the boost, tach and speedo. |

You guys think it would be possible to add a pulley on the main shaft and shift the charger forward a tad? I like PS and am trying to figure out a spot to run the charger off.

I suppose off topic, but as an alternative, what about mounting the SC on the drivers side where the power steering/ A/C bracket goes (went), mounting the TB under the SC with a 90 degree bend (with battery relocation and switching intake and AFM to opposite side), with output off the top running through a top mounted TII intercooler (maybe with a fan), then back down into a modified (sans TB) intake?
Rotard timing, run a rising rate FPR, SAFC, decent exhaust, wire/remove 6 ports, consider new fuel pump and injectors as necessary. Then blow engine, consider rebuid vs. TII block with S5 n/a rotors, porting and aftermarket fuel/ignition management. Thinking this would provide stable mounting, limit surge (with bypass valve), maximize validity of AFM readings (prior to new computer), provide an IC but minimize decrease in throttle response. Drawbacks would be PITA to get at sparkplugs and potential to cook ignition wiring. Not a whole lot of thought, just procrastinating/fantasizing. Any ideas? P.S. Maximum respect to young Mr. Brown, who receives the 2004 Mike G. award for innovation in the field of rotary power. |
How did you connect the intake and outlet piping to the SC? it looks like u used some type of adhesive.. I was wondering if a custom gasket would work as well?
|
so ya how bout some more infomation...that be nice
|

please make pics of the mounting brackets for the supercharger. thank you
|
i want a video
|
i just wanna see how he mounted the supercharger
|
dude zbrown just do a write up youll make about 100 bucks... shit i woudl do it in a sec.! 10 fc owners can send you 10 bucks vi apaypal... i mean it seems liek at least 4 balllers already bought the supercharger so help them out... plus your name will increase like your n/a rx-7!!!
|
hrm... I've been doing some reading about supercharging our 7's and have ran across some info mentioning dramatically increased wear on one of the bearings because of the supercharger pulling the eshaft in its direction... anyone know anything about this? I want to supercharge too( I have just about everything I need except injectors, header, and supercharger plus little bits like hoses and scrap metal)
edit: I also have a stock TII intercooler(need a hood... hehe) and I was wondering if I used that, would heat soak negate any gains?(or is heatsoak just a problem when not moving?) |

The video doesn't work anymore, i've already tried it. This project is awesome, there are (as always) room for improvements. Still awesome...just awesome. Hopefully by fall I'll be able to start a similar project. This summer i need to fix the cosmetics of the car.
|
video doesnt work? works fine for me. Nice work on the fabrication, I've decided that I'll be doing this modification myself, good job on everything
|
Okay, vid works. Z, I would still love to have a few pics of that mounting bracket if you ever get a chance to pull it out. I know you're working on a T2 intake manifold setup now but if you get a chance... :D

Hi , All
I was reading the forum and found this one on supercharging ......GREAT JOB . LOOKS GOOD. It's nice to see someone else that likes supercharged Rotarys. I have also. Here have a look see. http://members.cardomain.com/codeblue2 |

im not trying to be a dick, but what the hell is this supposed to be? ive been trying to figure it out for days now :( |

I just watched them too, someone must not of had their smoke or coffe, a bit shakey on the cam there. Ahh well. Find a dyno now ;)
|
Sorry to be a noob, but the NA FCs dont have LSD, or the same tranny / drivetrain layout as the T2s do they?
|
Na has a differnt trans, drive shaft, rear end half shafts, fly wheel and clutch than NA's
|
Have you considered making some of the parts then selling them ?
|
thanks sonicrat for hosting those
Sorry about the quality, It was one of my twin sisters who was running the camera. I cant connect at all if i drop the clutch even if i warm the tires up first. The first run was was a drop at 2500 rpm and the second was from a 5mph roll Here is a pic of the rubber i leave. I am getting a 4.3lsd and ditching the 3.9 open, you can see why Also i am working on intercooling my system because I have measured the temp on the intake pipe after some hard pulling with an infared Thermometer and it is at about 200 degrees F. I can feel the car lose power after it pulls a little bit because the manifold is getting heat soaked I have a track meet and have to go(It is the gayest thing in the world) I am going to buy a s5 tII complete intake system and adapt that to my n/a block. This will make intercooling an easy task because the throttle body on the TII Comes from the drivers side not the passenger side. I am going to hook up a front mount IC. I wont have a piping mess with the TII intake |
zbrown, where did u get ur bypass valve and Bov?
|
is the Eaton M90 the best fit for a 13b w/ 4 bridgeports. will it flow over the entire RMP range?
Anyone know what all of the factory Ford models came w/ this supercharger stock? What about a Bonneville 3800 SC? Might try this project myself Alfonso |

Anyone know what all of the factory Ford models came w/ this supercharger stock? What about a Bonneville 3800 SC? Might try this project myself Alfonso you're looking for the tbird super coupe from 89- a long time :-D or cougar xr-7. Those are not casted to the intake manifold. If you can find a 94+ supercharger that one is best. I think that the m90 would not move enough air for a good bridge... you'd be better off going with a whipple. you can get just the supercharger new for under 3k I think. check whipple's website. |

This thread is great and im definelty going to do the same to my car. I have the s/c and all the plumbing but still have a few questions. 1st, i would also like to know what blow off valve and bypass valve your using. I like the fact that yours is pretty quiet. The loud ones sound like the transmissions busting everytime you shift. 2nd, How the hell does your car not catch second like a champ, are you taking it easy when shifting? 3rd, are your auxillary ports operating?..I think im gunna use a RPM switch and the air pump from a lumbar seat but if it doenst matter than im not going to bother. And lastly this is my thoughts on an intercooler. Instead of an intercooler i was thinking of wrapping the exhaust manifold and making a heat shield to take care of some of the heat. I really dont wanna get into changeing over to a turbo intake. Any thoughts?
Oh yeah, seeing how your getting a new diff, how about a nice Burnout Video...Everyone LOVES burnouts :D |
Also will it be hard to use a Holly with it or is better fuel injected?
What size carb? The engine is a non turbo, Will it work? |

Any thoughts? If you want better boost from your supercharger, an intercooler should be on the upgrade path. You don't need worry the turbo intake swap zbrown is doing, its just what is working best for his setup. I would think having the supercharger mounted on the drivers' side would make plumbing an intercooler very easy. I think more people should be inspired by zbrown, and not copy his work as its a work in progress. If you NEED to copy him, then don't started cheapskating what he does. |

Oh yeah, seeing how your getting a new diff, how about a nice Burnout Video...Everyone LOVES burnouts :D now, why does he not need to actuate his ports? Because the purpose of the ports is to get air moving faster through the other 4 at low rpm's. This allows good bottom and top end. But, since the supercharger is forcing the air into the engine instead of the air being sucked in like it normally is, we want as much port area as possible at all times. |
monkey wants to change the design to not use a intercooler. He wants to follow zbrown's design, but doesn't want to follow the intercooler route because of the specific intake mods zbrown is doing.
A heat shield is not an alternative to an intercooler. |
The m-90 can be found on 89-95 t-bird sc's and mercury cougar xr-7's
|
I will mount my eaton m90 on the drivers side, and get a FMIC and custom pipe it.
NP. |

I'm waiting for my M90 to get here so I can see. |
There seem to be a few Eaton M90s for Mustang, ford 3.8L V6 on the eBay. Is that the one?

i wonder if this would work on my 85 GLS-SE:confused: guess I'll have to try it and see.
