Spacer increases plenum area..Now I dont think it will work under a stock hood

 

[OxmanWI]

S-Porting is an “efficiency” port job that’s performed to all of the M90's supplied with the AED kits.

What kind of numbers are we looking at after an S-porting job?

 

[A-Train]

You have...

AwdRocks,

You have a REV-II kit, period. Don't let anybody tell you anything different.

Slowpoke,

That is not the spacer I was referring to. This is the 1" plenum spacer I made for the REV-I kits. I still have a few left.



AwdRocks,

Obviously my spacer won't work for the REV-II design since they have the inlet entrace going through the rear portion of the plenum.

As for discharge temps on my 10 psi set-up. I'll see 160 degrees F. at WOT on a 90 degree F. day. On a 100 + day she will climb to 170. When it's 20-30 degrees F, I can hardly get the temps over 70 degrees F.

Josh,

All AED REV-I kits have S-Ports. Most REV-II kits as well. The newer REV-II blowers that are GEN-V Eaton M90 superchargers DO NOT have the S-Port since they DO NOT need it. The best of the best, so far is the GEN-V blower case that ALLEN uses.

ModCat do you have a REV-1 or 2?

Mine is a REV I and looks like the picture that A-Train posted below.

Nevermind, better that other guys see this so they can learn too...

This is the 1" plenum spacer I made for the REV-I kits. I still have a few left.

You made those? How much are you selling for?

EDIT: see post below

Couple questions....for the Allen guys since you’re here….

1) Can I port the runners in the REV-1 Manifold on the stock NPI heads?

2) Will an external polish job and power coating hurt any thing on the out side (for looks)

3) Can I port the Supercharger even if it has an already S-port?

 

[A-Train]

Brian,

The program could be adjusted if I had either a print from Allen Superchargers or a REV-II plenum to work from. Neither of which I have. If there is enough interest, I can start making the REV-II spacers.

I pulled out of the idea when AED went belly up. I figured no more new kits means no more new customers.

Then there is the material costs and machine costs. The spacer idea could be revisited if enough people were flashing the cash.

Josh,

The spacer increases plenum volume. It "can" fit under the stock hood if you cut all the bracing out (WHICH I DO NOT RECOMMEND), just ask Blown96bird. It will easily fit under a cowl hood.

Does it add power? Can't say for sure, we have never had anybody do a before and after test on a dyno. Should it help add power? Theoretically yes. Has it been proven in the past, yes. The idea was basically founded by Jerry W., with his personal tests on the Kenne Brown AED Crown Vics.

I will sell any remaining REV-I spacers for $200.00.

Good deal, wish I would have know that a month ago. It cost me $275.00 to have mine made up. $100 for the chunk of aluminum and $175 labor on the CNC.

Exactly what happened to Steve's set up when he removed his hood bracing? I ended up having to cut mine as well, but I only removed the center of the cross sectional area that was right over the plenum and left the remainder of the bracing there.

What about your hoses, do you have them in another path, i have mine over the top.......

 

[Mod Motor Cat]

I'm forced to build a custom inlet tube for my set up since going with the 75mm T/B and 90mm Lightning MAF, so since I'm doing so, I'm going to move the hoses a little further towards the front of the car and run them in front of the intake somewhere.

That's one clean MN12 you've got there. :thumbsup:

 

[A-Train]

What?

Brian,

I tried to sell you a spacer and I'm sure Mike Siska would have told you I had them for sale. Originally, they were $300.00 and that was breaking even. Now I just don't want them sitting around here anymore so I'll sell them at a loss.

$275.00 is not a bad price, don't feel bad.

As for Blown96bird's hood, I have no idea what happened to it, but cutting the bracing out surely weakened the structure. I know he also added a hood scoop as well.

OxmanWI,

You ran yours the way AED instructed you to. No problem there. The real PITA are the '94/'95 cars that need the wiring harness lengthened (the injector pigtails, etc.). All you need to do is, fix your wiring harness to flow away from the top of the cover and re-route the IAC hose and breather hose. A few elbows can fix that.

The spacer still won't clear the stock hood though.

Yeah I'll be getting a cowl hood before next spring, so i wont have to worry about that. Questions for ya on post #26.

Answers....

Sorry I missed them.

1) Can I port the runners in the REV-1 Manifold on the stock NPI heads?

YES. As long as there are the Coil-On-Plug provisions. You lay some Dykem lay-out fluid on the runner then the PI gasket on the runner. Then you use a scribe to outline the port shape. Then you need a good end mill to start the process. A CNC Makino could do it quickly. Once the port is close, you can drop back and punt and use a Dremel or Fordum to grind, shape and polish. Air tools work also.

2) Will an external polish job and power coating hurt any thing on the out side (for looks).

Polish job, no problem there. Any powerd coating or paint will retain heat in the plenum and runners. How much heat...hard to say but you can check with a infared thermogun before and after...although its too late by then.

3) Can I port the Supercharger even if it has an already S-port?

YES. Sure can, but it has to be done correctly. I recommend somebody who has experience, ports it. You want to create velocity to the inlet side of the blower. Do not just use a Dremel. Bad idea.

Porting and polishing the runners is a great idea and won't hurt anything since the runners are so short and boost builds so quickly.

Thanks for the help guys, I'm always learning some thing new and that's a good thing!

A-train I'll be contacting you soon about that spacer, how many do you have left?

 

[A-Train]

Not sure but I think...

I believe there are 4 left. I'll double check tomorrow when I get to work.

Let me know when you are ready. I've sold spacers to a few guys here and I know they were satisifed.

Rev II Spacers Say "I"

"I"

Ill take a RevII spacer. How much for an old buddy?

I think ill have to start a thread for group buy.

Questions:

Do you know how much the Gen-V blower cost?

A port job on my blower is $375, at least what ive investigated up till now... from Stein.

Will the GEN-V blower bolt right up to my RevII?

Is the GEN-V blower basically JUST the case the rotors sit in?

Here is my plan before the race kit. Once I have all this in line the race kit will be pretty much ready to rock and roll with its new fuel system.

But im confident that this setup would RIP:

1) Plenum spacer
2) Ported blower or GEN-V blower
3) 8rib pulley Kit
4) 3'' blower pulley
5) 8.5'' crankover pulley
6) Electric water pump
7) 60lbs injectors
8) BA2400 MAF

Those pulleys should net me about 10psi with my great flowing motor and exhaust, numbers come out to about 12-12.5psi, but if I could read on my gauge 10-10.5psi I think it will shred.

I'm also going to add a smaller nozzle in my plenum for the meth/water to bury those IAT's. The nozzle before the throttle body is not quite cutting the heat. So two small nozzles, one before and after the blower, a check valve before the nozzles and the safe injection for safety. Add timing and tune for the meth/water, should make this setup absolutely rip.

I don't see why I couldn't get another 80-90rwhp with this combo :thumbsup:

How much does the twin screw upgrade cost anyway? My current engine made 628 to the rear wheels with a vortech....Sadly I'm hoping for 400 MAYBE with the ported m90 and revised inlet.....Sad...sooosad

The race kit I think is right around $4,500. I only wish I would have known about it when I bought my little M90. I would have just bought the race kit and de-tuned it for my stock internals at the time. But even at that time I had no idea I would be this deep into the mod bug.

I'm hoping to be in the neighborhood of 600+rwhp when im all said and done with the race kit.

Why did you get rid of your vortech?

Yeah, I remember talking to you about a year or so ago about one. If I recall correctly the price was $300 at the time and I wasn’t far enough along with the car at that point to justify spending the money. I was also concerned that after shipping cost to Ontario, brokerage fees and the exchange rate, I could have had my own made for less money. Had they been $200 at the time we spoke, I would have jumped on it. It would have cost me about the same amount that it cost me to have mine built, without the added aggravation of running all over town trying to find a machine shop that would even do it for me. Ahhh well, It wouldn’t be the first time i've spent money I didn't need to on this project. .

How much does the twin screw upgrade cost anyway?

I spoke to Scott a few weeks back and he told me to upgrade to the Whipple from the current M90S would cost anywhere from $2,500-$3,000. His cost on the screw compressor alone was $1,800. Keep in mind though, that doesn't include the cost of the needed fuel system upgrades and Mass Air Meter that would have to accompany it. He told me that they were currently having problems with the company currently producing their manifold castings and they probably wouldn't be able to put a Race Kit together until late this year or early next year.

So my RevII manifold will work with the race kit? If this the same manifold that is sold with the race kit?
