So Very Supercharged

[somedude_001]

Did you already try the computer.. and know something we don't.

I absolutly commend the custom work you guys are doing i think its great! but the eaton M80 (i believe it was a m80) was used on a SHO and they don't flow enough i think the person made like 250~WHP with 10psi I don't rember exactly or i might be making up the whole thing. i definately have a video of one though.

as far as using the Tbirds management i think its a cool concept but i don't know how well a restrictive 3.8 compares to a high flow 3.0. just be carefull I would hate to see it lean out because the SHO engine will suck the life out of that blower.

I assume the Tbird computer has no provisions for seccondaries right? so they would be open all the time? I honestly don't think the SHO engine even needs secondaries to tell you the truth.

You can take care of the secondaries real easy. Just get an RPM module (you hook it up the same way you hook up a tach) , and make it so it turns the little electrical air valve on/off. (the air valve that releases the vac to open the secondaries when turned on, next to the vac cannister).
This way you can open the secondaries whenever you want based on RPM.

I would like to keep the secondaries. I have cams and it really helped with the low end torque. I am not gonna run the car up and down the streets until I have my EGT guage and so on. If it does turn out to lean, then back to the idea of the SAFC or something. I guess we will see. however, it isn't going to be done tonight because the machine shop didn't finish welding the cap for us...so tomorrow or wed for sure.

That Supercoupe blower certainly produces an interesting whine, doesn't it?

Yes it does.

The SHO motor outruns the original gen 1 M-90 with a stock pulley at about 5000 rpms. With an undersize (overdriven) pulley it still sucks all of the positive pressure at 6000. But it's still a blast.

SHO motor+ ANY forced induction= One helluva good time.

NCTaurusSHO = 3 'charged SHOs

based on what I have seen, the SHO eec will probably work just as good as the SCTB eec. did you try that first? if not I would try that to make sure it WON'T work before you go to too much hassle with a grafted-in computer.

the next step is a video of your Turbo SHO Vs. your Roots SHO. to definitely prove which is better.

 

[NCTaurusSHO]

we were jsut thinking about trying it with just the injectors and the supercharger first. (just a few minute ago actually) weird. probably gonna see how that works then go further with computer stuff.

 

[bobreimer]

pretty creative ..... how does it run?

 

[Mike Kopstain]

The two vehicles were Ford's first to use a MAF & DIS system. They use the same MAF, same DIS, and both use the same MAP (I believe). You really should have minimal tweaks to do to the Supercoupe PCM to get it to work. I can't beleive it fired up with no changes!

Forget the secondaries. With the roots blower they are just going to get in the way. Remove the blades and the shafts from the assemblies and just run them straight. If it were a CSC, turbo setup the secondaries would be a little more important but with the positive displacement blower you'll have all the torque you need with them gone.

Are you running a bypass valve on there? That really will help your gas mileage as well as take some strain off the blower. You don't get that cool whine at idle but you do save some stress on the rod bearings.

True, though there are still many key differences between the two calibrations that will keep the Supercoupe PCM from running optimally on a foreign V6 SHO configuration. What's more is that you will eventually need to retune the PCM (whether it be from the Supercoupe or the SHO) to achieve optimum mileage and maximum peformance from the entire setup.

OTOH, I definitely applaud you guys for both your ingenuity and your creativity. Keep up the great work!

 

[NCTaurusSHO]

thanks. We are hopefully gonna be getting it all done tongiht, and we'll try to post up some more video with it done.

BTW, yes, there will be a blow off valve-not bypass. We just did rod bearings a month ago. Remember, this is the one with the stage 2 cams, ported/polished heads w/ oversized valves, honed/extruded intake runners.. and so on. we are hoping for good results w/ the supercharger. it sure sounds like it will be a blast to drive.

 

[twr]

Stage 2 cams with a positive displacement blower?? Err... I wonder how well that's gonna work.

 

[NotSoSlowSHO]

Not very well Im assuming.

I didnt realize how modded the engine was.

That engine will probably be sucking the life out of that blower by 4000 rpm.

 

[somedude_001]

but it will be really fast untill then. if you are interested (i know a lot of your stuff is ona extreme budget) M112 blowers can be had pretty cheap off of cobras that are upgrading. my brother got his for $300

Yes, and they are 3 gen blowers I believe, much more efficient at moving air.

And the bypass is a good idea, there's no need to be boosting at idle. I love your creativity when it comes to these cars, we need more Dr. Frankensteins out there.

Removing the butterfly plates is also a good idea, but leave the shafts in to make it easier to keep the holes sealed up. Good luck.

(Lets say..for now... i was putting these mods on a N/A motor with a supercharger ) Adding cams, ported heads and intake runners on a N/A motor with a postitive displacement supercharger is shown to reduce the nuber of lbs.that a blower produces by about 2-4lbs. However, it does up the volumetric efficiency of the motor itself, which reduces the superchargers need to move air into the engine (doesn't have to work as hard) In turn, there are very positive results to be seen as long as you are able to bring your boost numbers back by making the supercharger spin faster than the crankshaft and to what it was originally without the mods...whether it be with a pully or other means. When we try it with this larger pully on first, if it does seem to fall flat after 4000K then we have a 10% pulley capable of 3-4lbs. more of boost. that should bring the supercharger to the speed that we need it. if not, then we'll get an even smaller one. -ashley-

I was under the impression from many, many, many SHO owners that you can't FI your car without upwards of 5000 dollars... looks like he did it with less then 2k . I'm really curious as to how much all the machine shop work costed you etc. As i'm coming across like 4k in the next couple weeks and if the price is nothing crazy id like to maybe try the cobra blower? I have a long cold, SALTY minnesota winter ahead of me, if this works out for you id love to start picking up a piece here and there over the winter! so definitely let us know!!

 

[NCTaurusSHO]

actually the jackshaft and coupler were 100 and the cap isn't much either having it welded up (picking it up today not sure how much). we did everything else our selfs .... no money at all other than that. all spare parts off of spare cars. all the bracketry was mad by paul, and we have an exhaust pipe bender and pipe here at our shop. free is the best.

 

[Brett]

Well i absolutely hate wiring, so id prolly have to go the tweecer route, but thats 500 dollars, with your setup (not being as mechanically inclined as you) id prolly be looking at a bit more then 1200.... which would be saweet. Any boost is good boost.

 

[NCTaurusSHO]

yeah, depending on what works and doesn't we might go the route of SAFC or something. we haven't gotten there yet.

 

[twr]

My point was with the overlap of the stage 2 cams you will be blowing a lot of a/f mix out of the cylinders into the exhaust.
