Hey Guys. I'm new to this forum. I usually hang around miata.net, but I've realized that this is probably a better place to talk power, as most over there are narow minded irresponsible children. Anyway...

I'm putting a millenia supercharger on my 99 NB. I got the bracket that bolts the blower to the exhaust manifold made and installed on the vehicle. I've decided to run the blower unthrottled. This will increase throttle response, reduce intake air temps, and reduce the temps of the blower.

The blower has a 4" diameter 8 rib pulley on it. The millenia it came off of had a 6" crank pulley. I'm going to make a 8" pulley to go on the crank which would make for a 2:1 ratio. I was thinking of making it a 9", but I'm not sure. I'm worried I may be spinning it too fast. If I can, I'll go with a 9". I'm not sure what the things rated at.

It's a 1 Liter/ 61 Cubic Inch Lysholm Twin Screw with oil supply and return lines. If I knew it was rated at 16K, I could use the 9" pulley for a 2.25:1 ratio blower spinning 15.75K RPM's@the motors 7KRPM's.

I'm really wanting to go all out on this. MS II, WI, No intercooler for now, Supra Injectors, Walbrow 255 or just build another fuel system to replace the car's original. I hoping I can hit 250-300 WHP before I hit the nitrous.

I got some pictures but I can't figure out how to post them.

Here's a link to the thread on this at miata.net: http://forum.miata.net/vb/showthread.php?t=237266

Welcome to the forum that is one awesome build. I love watching DIY setup's like this. iweasel on the forum was doing something similar at one time, not sure what the blower was from though.
Why the walbro 255 though, many on the forum use the walbro 190 lph because the 255 is overkill. Truthfully with the right injectors and MS you shouldn't even need the FP in your '99.

What are you going to use for a tach input for MSII, 94-97 CAS or are you going to use Arga's circuit to make it work?

I figured I needed the 255. I could probably use the 190 I suppose. What's "FP"?

I'm not sure how I'm going to do the ignition. I was originally planning to do MSII with Ford EDIS-4. Now, I'm told it's possible to utilize the 99's pickup, but you have to do something and it's highly untested blah, blah, blah. So, I'm very uncertain. Would a CAS from a 94-97 work? I was told that MSII couldn't read that signal, but that could have changed.
What's Arga's circuit?

FP meant fuelpump, sorry for the acronym.
Don't use EDIS, it's not worth it. Truthfully i don't know why you want to go MSII. The only reason I would go MSII is so that I could run sequential injection and sequential ignition(if it's even possible, i haven't researched it.) I run MSI with a 94-97 CAS in my '99 using the stock coils with plans to run a set of Toyota COPs later on if my '99 fail me under high boost.

Arga was the first guy I know on the forum to run MSII in a miata, especially in a NB. He has some sort of circuit that inverts the miata's output I think but recently he might have figured something else out to make it so you don't have to do anything special because they changed the code to read it right or something. Now this is all be spewing out info from what I read but i'll try to find the link and to his recent writeup for you. He isn't running MSII-E, just regular MSII.

That thread is by him and has the link to his current MSII action.

I was thinking about the EDIS-4 since I have to make a new pulley to go on the crank, I could integrate the 36-1 wheel into the pulley while I'm machining it. If someone's got a way to utilize the factory ignition and let MS II control it, that's what I'll do. Yea, I had a debat on M.net about MS I vs. MS II and I decided that I would rather have MS II.

cjernigan

iTrader: (13)

For the resolution or what? I won't argue about it. MSI is easy and it works fine for my usage. Though in the future when MSII has a few more functions like MSnSE i would like to run it for sequential injection/ignition and the higher resolution.

patsmx5

iTrader: (16)

Yea, for the resolution. I figure if it's in any way going to help it run a little bit smoother/better it's worth it. For unknown reasons, I have the miata that runs lean. I made the situation worse by raising the rev limiter. Then I did a lot of head work to get it flowing and now it's running even leaner! I can actually turn off the nitrous bottle, turn on the nitrous system to come on at 10% using my controller, and add only fuel and it really helps.

I was set on MS I when I saw all the cool little features it has to play with, but I think I would rather get MS II and wait for new features for it. The more that buy MS II, the sooner things will be developed for it.

Sounds like a plan to me. Maybe Arga's stuff will help you. Become a member of that forum and download that MSQ to make sure you have it in the future.

iTrader: (16)

What forum do I become a member of? What's MSQ-MegaSquirt...?

cjernigan

iTrader: (13)

.msq is the filetype for Megasquirt when using Megatune.

I was saying you should go to that link i posted, check out that thread of Arga's. Then become a member of that forum because when you're a member you can see the files they have uploaded with the ability to download his recent .msq.

diyautotune.com is your place to get all your megasquirt products, I don't mind plugging them because they offer awesome service and they help ALOT on the forum and in the miata community in general.

Ah, si. Do you know how to post pictures on here? On M.net, you can upload them.

cjernigan

iTrader: (13)

The best way is to get a free photobucket.com account and then insert the "[img]" tags here. That way they show up as a picture instead of a lame link.

Otherwise in order to just upload them you have to be a supporting member. It's around 3.50 a month to do that. I still prefer the photobucket method though, it works really well and is free.

You don't even need the 190. The stock pump will do 300rwhp.

iTrader: (16)

Really? I've always been told it won't, but I'm all ears for not wasting money on parts I don't really need.

Note the proportioning valve has been moved to the other side of the maste cylinder. That was fun!

iTrader: (7)

Yes for 300 but if you run your spray the extra 100 then the stock pump is gonna be crying, and also i dunno how your aux pump is setup wether it picks up seperate from the main pump or what but that would help us understand it as well. As always i love your enginuity and if you wanna solder anything or run some direct port nos lines for my car lemme know.

cjernigan

iTrader: (13)

The only reason people swap their pumps out on here is because they have an older car and the pump is tired.
That NOS is badass, i don't know anything about nitrous, is that a dry or wet shot?

Lame plug:

You can buy my MSII CPU for $60 shipped. I was attempting to make it work with the 1.6 cas but With the COP's I couldn't get it to run right in the time I had. Now that school is in session I don't have the time to mess on the car and burn out more COP's since its my DD. The new cost for the CPU is $90+shipping.

The nitroius is direct port wet shot, 1 fogger for each cylinder. I installed a seperate fuel system for the nitrous. I installed a 3/8's pickup tube into the sending unit, a 300 Liter pump, dual parallel fuel filters, 3/8 hard fuel line to the solenoid, and all new relay's and wiring. The two systems only share the fuel tank.
It's and Edelbrock Performer kit rated at 50-180 HP. I have the 100 shot jets in it right now, but I'm tempted to put in the 140's. It has all stainless hard lines and the new E2 Stainless foggers as well. Pro solenoids too. I also have a Progressive controller and a 2-way MSD Digital adjustable Window Switch. The controller and Window Switch are in the glove compartment, the arming switch is in the ashtray, the Wide open throttle switch is under the gas pedal (out of site), the armed light is resessed into the air vent. Fuel pump is bolted to the front of the drivers side rear fender. Foggers are under the intake manifold out of site.

The car's original fuel system is stock, but It has a new OEM Pump.
