How much overdrive can you see in those pictures????



5% blower pulley
5% JS pulley


Not going to try this out yet untill i get the other bugs worked out :)

BTW thanks manny! worth the wait awesome work very awesome price!


With 10% OD (i think this is safe for now hehe) I can tell a huge diffrence off the line only about 1.5psi or so but it comes on ALOT sooner... 11.5psi or so i can see at the upper rpms.. I have the 10% crank pulley sitting there waiting for later when i run it i think i'll put the stock blower pulley back on for 15% total overdrive (i am at 10% now) when i get the 42's in id be tempted to see what 20% will do...

[thunderkid84]

as long as u dont dectect any pinging u can OD your heart out.

but i think 15% will be good until u do some porting to the blower. or lose some restriction in your intake system (i.e. Dbl IC, front mount, etc.)

i wouldnt be driving it too hard cuz ur injectors should already be close to maxing, if not already.

[fturner]

With a single IC and just a fan... don't even bother. Honestly, don't even try over 5% till you get a D-IC etc. The ACT's are going to kill you. Sure you'll snap of the line for the first 60ft, then your toast after that because the car pulls timing when the ACT's get over 120F.

Heck with a single IC, ported 94 blower with the equiv of 3% OD, pegging the boost gauge, and in this cold weather around 32F I hammer it and after the equivalent of about an 1/8th mile I'm seeing ATC's around 110F.

Have you gotten another blower for that car yet?

[CMac89]

Sooooo.......basically stock exhaust with 11psi and wondering why it's slow.

That's like me saying; I don't know why people call my pet a dog when it has hair, a tail, and barks.

On your list of goodies needs to be a good exhaust including aftermarket downtubes. Try to find a late model blower, too. I was running 5% OD and made 17psi. It made 270rwhp and 388rwtq with an intake, stock late model blower with an MP inlet, and exhaust. Stock intercooler and everything.

i 2nd that. these late models are awesome. with a 5% on my unported late model i made 15 psi even with the FMIC, ported heads, full exhaust.

[Jacob_Royer]

Exhaust consists of gutted cats no mufflers and the resonator still intact.. couldnt be that restrictive (yes i know th resonator is restrictive....)

[rzimmerl]

couldnt be that restrictive

Yes it is, including the pipe diameter

[Jacob_Royer]

I got a qoute the other day... Going to get new downtubes made with 2 glass packs in them for calming down the exhaust not e a bit.. a flowmaster Y into a 3/2.5" dual outlet flowmaster, 2.5" duals out of it and out the back.. run me about $250 for everything (have the muffler already) should be able to breath then!

[S_Mazza]

That is a crazy low quote. If you can get good work at that price, go for it!!!

That sounds about right for run of the mill non-mandrel bent stuff for around here, if not a bit high if you privide the mufflers.

I did dual exhasut in my truck, where I provided a specific muffler for the application, and they charged me either $150 or $175 for the whole truck minus the mufflers, in aluminized pipe. Sounds like a fair price, they didn't even spend an hour doing it, and onyl one guy worked on it.

They charged me $75 to replace pipe between the factory resonator to factory Y with 3" pipe; and replace the stock mufflers with some used flowmasters I wanted to try. I had to do the reaonator at amore backwoods place, as they had to remove something else at the same time;) again fair, only took him 15-20 minutes.

Next time I have any done, I'm gonna order some mandrel bent pieces of my own to tack together and have abuddy weld em up "right" Cus I must say none of the bends I have look very efficient.

This thing is starting to feel halfway fast!

[95_XR7]

Halfway fast? No need to rub it in. Your SC would absolutely destroy mine. You can't say something's wrong with it, unless you drive mine. There must be something wrong with mine now.

u didnt boost as much as i thought u would. but it definitely seems faster.

so its a total of 10% OD ?

[Jacob_Royer]

yeh 5% js 5% blower pully.. Once i get the injectors in im going to put the stock blower pulley back on and the 10% crank for a total of 15%... I opened the blower up crazy on the oulet...Probably to much... i make the v about 5/8" wider...

[Jacob_Royer]

What i cant figure out is why it pulls really hard in 3rd compared to 1st and second.. notice how hard it pulls when it shifts into 3rd?? boost even jumps up a bit you can see it go up... Maybe i need to change my tranny fluid?? cant i shift this thing safely at say 5500rpm or so with the cam i have?? shift points need moved up a bit..

[Mike8675309]

Run it on a dyno and check your power band. That would probably explain the feel you have based on the trans ratios. You'll also then be able to figure out where your ideal shift points would be for your current power band.

[mannysc]

i ran these two pulleys with a 5% blower pulley and a mp111 style blower and ported intake ported exh ported heads ported enlarged return plenum ,
modified stock exh and made 11 lbs boost at 2000 rpms and 18lbs boost at 5500, it never made any more than 18 lbs but my heads are really ported to hell and back.

oh yeah had 42 lbs injectors went 13;22 with this on stock short block changed cam but never ran it ob strip but boost went down to 15lbs with cam change,

no ping on 91 pump gas on 70 deg day .also no tune

bottom end is really absurd with 20% od and 327s in rear.

neat thing is nobody notices they are od pulleys because i made them from stock pulleys they have ford written all over them.

I agree, and actually...after I get some new injectors, and that FMIC installed I'm going to get it dyno tuned.

Sorry for the voices in #2, my little brother and his friend were with me. Also, these were on a warm night, and I wouldn't be surprised if it was pulling some timing. You can tell when I hit teh posted speed by when the video cuts off, or when I let off the gas.

[Jacob_Royer]

That does seem slower ? ? I would think it would be faster considering the late model blower/early model pulley and all the other stuff on there..

I have

stock injectors

stock maf

early model blower

stock IC w/fan

stock tb

stock tune

and a very half ~~~'d exaust with bad leaks near the manifolds

[Jacob_Royer]

227 RWHP & 318 RWTQ

Is this current? seems low for what you have done???

Not sure how current that is. That's the exact same thing I was thinking.
As far as it seeming slow, I'm guessing it's pulling timing. It's not spinning the 18x9's at all in the video's which it definitely does when it's cold out.

My guess is it's pulling timing, and I know for a fact I have a nice exhaust leak on the passenger side, right before my O2. (which accounts for that side running so dang rich.)
Also, I'm sorry to hijack, I was just pointing out. Your car may feel slow, but I bet if you put it on a dyno, or race the stang and the SC at the same time...the SC will win.

Btw, if I was you, I would definitely upgrade injectors, intercooler, and then get it tuned. Your air charge temp has to be extreme running 10%, and I wouldn't doubt you are close to maxing injectors, if you haven't already. That right there should definitely wake the car up.

[thunderkid84]

corey,

i really doubt you're pulling timing with only a early pulley on and a dbl IC. i think u need gears !! at least go 3.55. the lower gears will turn those 18's faster, making your SC get up and go quicker

is the a/c deleted ? get a shorter condensor and a fan and that thing will do almost as good as a front mount.

The reason I say it's pulling timing, is because thos videos were after day of driving, and it was still about 80* out. I didn't give the car a break at all. But yeah, looking at a front mount, and then shorter a/c condenser.

And Jacob, sorry about the hijack. Wasn't my goal.

yea sorry jake :)

i'd say the dbl IC is plenty for u right now. save your money and go with a shorter condensor and a fan. then put the money u save into gears.

[Jacob_Royer]

i dont care hijack away! :) I still think my car was faster stock than it is now :(

[mannysc]

I thinkyour blower case may be worn or rotors bad bearings my sc just lost boost and its bad bearings at rear of case . ireplaced them and installed different set of rotors my boost went up 2 lbs.

[sizemoremk]

My home ported blower was beginning to make weird sounds recently, in addition to a rattle at idle. When I first put my home ported on, it pegged the stock boost guage pretty quickly, then after a a few weeks or so the boost seemed to drop lower until it only got 12ish pounds according to the stock guage. I assumed it had a boost leak that I couldn't ever find and I never got around to testing it with a compressor. Or maybeb belt slip, or both.

The home port looked something like this shown below with a ported inlet I made up via scrap aluminum pieces and cutting the whole neck of the inlet so that the whole diameter was bigger. It seemd to seal pretty well as I re-powder coated it after spraying that copper spray over the areas I welded.

The blower looked like an idea I had awhile back for an easy method for home portin, but quickly found out manny already did blowers this way... It was fairly similar to the pics in this thread.
http://www.sccoa.com/forums/showthread.php?t=55015


I believe the rear bearings went bad pretty quick, as I didn't replace them after welding on the case (mistake:o). But I was impressed with my work until it started making racket and loosing boost. The blower noise recently got really bad so I parked it unit l swapped on the MPIII I just bought from Kevin a few weeks ago.

Oddly enough the car seemed much faster, but seemed only about as fast as I remember my home ported blower feeling when I first installed it. ALOT quieter now, hits the 15lb mark pretty quickly again but weather and traffic really hasn't allowed for a decent pull through all of 3rd gear. But from what I can telll on the low end, it really didn't gain all that much between my home port and the MPIII... Maybe a full pull will change my mind, that or a maybe an 85mm TB and larger cold air intake. I'm still runnign the 75mm and a MAC cold air setup. I still have to believe that with the 75mm TB, pulling the air from down in the fender well has to be better than taking it from the engine bay, air divider or not...

Didn't mean to hijack the hijackers ;) but I guess my point is that if the bearings are shot and the case is leaking in the rear, you will loose significant boost.

When I took my home ported off, just spinning it by hand yielded an aweful scratchy sound... That and the fact that the pieces of aluminum I evidently poorly welded into the sound ports popped out of one side (I fished it out of the top of the double IC)...

The MPIII sounds more sneaky, or menacing than the home port. The home port was louder, and whine was loud from time you went WOT; the MPIII gets about as loud, but it seems like it has to work up to the louder "whine levels".

[Jacob_Royer]

I thought about swapping a stocker on there and see what happens

I had a 75mm TB and 3" ZR intake with an MPII and pulled 360 rwhp with a non locking AOD....only gained about 10 rwhp going to an 85mm TB and 3.5" intake. The MPIII may benifit more from the larger TB because it likes to be overdriven more.

Man did the car feel strong this morning:D

This morning was the coldest the car has seen yet, 25 degrees (12 with windchill:() and pegged the boost guage and got sideways at about a 40 MPH roll:D:D:D

Unfortunatley I think at 25 degrees, my IAC gave out. I have my EEC tuner set to kick up to around 1000 RPM when A/C (or defrost) comes on and it was hard to start and continued to idle real low almost stalling at the stoplights even with the defrost on:(

There was a CEL, so I'll check the code this evening...
