I am working on a project to supercharge my xB. My goal for this project is to make a VERY affordable S/C system and, once tested, make it available as a kit for other xB owners.

Here's the skinny....

The blower I'm using is a roots blower from early 90's GM products. It is the Eaton M62, I got mine off of a 1992 Bonneville SSEi.

How I will make it work on our engine.....

I am in the process of building mounts that will place the blower slightly above and in front of the valve cover. Once mounted there it will be bolted to a plenum of sorts which will take the boosted intake charge and plumb it into a tube towards the drivers side of the car. I'll run the boost through an intercooler in the bumper and back up into the stock throttle body.

I'm not shooting for HUGE hp numbers here, simply trying to make the xB a little faster and more fun to drive. I am shooting for about 160-170hp at the wheels.

Now I bet you are asking about fueling......

I have a friend in the electronics industry that turboed an Escort and he designed a circuit that controls a 5th fuel injector. This circuit is also adjustable to fine tune when it comes into play and how much effect it has.

The 5th injector controller reads the signal from the MAF and the O2 sensors and uses that infor mation to determine when to turn the 5th injector on and for how long. It's a relatively simple device that will allow me to squeeze out a little more power and not cause the idle CEL's that are common with larger injectors.

Here are a few pics of what me and my friend in this project have done so far.......

I've been following your progress over on the other board and it seems to be the safest bet for my automatic and internals as far as boost goes. (There's a really interesting ITB setup that I like too on this board) 150 is nothing to sneeze at in these cars. Good luck and too bad you aren't out in California I'd be a test mule for the auto. I would be willing to try to pass off the supercharger like it was from TRD,lol. Powdercoat it black like the older tacoma ones and slap on a TRD sticker. I don't think you'll get as many naysayers here as you got over there.

Sounds great in theory, hope all goes well for you and u r successfull. Keep us updated, and maybe...just maybe we will become new customers of yours!! Doesnt hurt to attempt something like this if u know what u r doing, luck! Oh, and 150-170 horses at the wheel? Are u nuts, that is haulin ASS in these cars, thats double what they come stock. I would giv a nut to have safe power like that in my box.

i still am against it. but hey lets see it work guys. good luck.

and 150-170 is not double the stock horsepower. maybe double the auto's hp.

but yes it will be fast.

one thing is i'd advise against the 5th injector. but that's just me.

:) Thats what i meant, stock above 100+ at the crank, 75-85 at wheels, double at the WHEELS, there, i will spell it out, everyone who has half a brain knows what i meant. Good day all!!!!

Regarding the 5th injector: it has to increase fuel to all cylinders equally- difficult task to achieve on a dry manifold (unlike carburator or TBI intake- it is build to move air only, not the A/F mixture). I think it will really confuse ECM alot about what's happenin'
I like this project. Why not just put the basic stuff together and then clean up issues with enrichment, etc as needed later

First to reply to you....

This kit will work the same on an auto car as it will on a manual trans car. This system does not reprogram or interfere with the stock ECU in any way. This system and the 5th injector controller simply compliment or work in conjunction with the cars stock ECU.

As for the 5th injector naysayers......

This system is modeled after my friends Ford Escort. He put a turbo on his 1996 Escort LX which is a standard OBDII system just like our xB's. The fifth injecter is places right before the throttle body and does a decent job at dispensing fuel to all the cylinders. I mean by the time the fuel is being added, the intake charge is at 8psi and moving through there rather quickley why wouldn't the fuel dispurse through the air well?

Anyways, back to my friends Escort.... That thing is turboed with this same 5th injector setup I am doing. He dynoed his car stock at 88whp. He dynoed his car after the turbo setup at 212whp and 262 ftlbs of torque! He took it to the drag strip, run it down the track and completely disingrated his differential half way down the track. He shut the car down and still had a trap speed of 100mph!

I didn't need to say all that, but what I can say is this system is tested and it works. I just have to adapt it to an xB.

hey man, thats cool! I wanna see it work!!! Sometimes, simple is better. Can we get more pics of it mounted, like a over shot?

Hmm, it does sound VERY interesting. Would it require the use of higher octane fuel? (Sorry if it sounds like a dumb question......
)

75-85 is not stock at the wheels horsepower.the difference may be negligeable but it's a difference.

auto's normally range from 74 to 86 and manuals from about 89 to 96

how do I not make sense? stock whp for auto's range from 74-86whp. but manuals range from 89-96. and 89-96 whp doubled is more than 150-170 whp. 89 doubled would be 178 . 96 doubled would be 192 .


last I checked 150-170 is different than 178-192 for manuals . his numbers are pretty correct for auto's but NOT manual cars.

At 8psi and about 150-160whp you would have to run premium. If you put a larger pulley on it and ran a more conservative 4-6psi you would have less power and probably not NEED premium. I would still run premium though.

And who gives a **** about the difference in hp between an auto and a manual xB, I mean really.

Any ideas on how much this unit will cost? I'm interested.
When I am done with this system and I have it operational on my car I will be offering up kits for sale.

The kits will include everything you need except the blower. It will be up to you to buy a used or remanufactured M62 blower to go with the kit. At any given time there are several of those blowers on ebay so finding one should not be a problem. There are also S/C GM forums you can probably find them in.

Anywho. I am shooting for a kit price of $900-$1100 depending on how much the prototype costs me to make. On top of that the blower will cost you $150-$250 used or about $450 remanufactured with a warranty.

The kit will include:
Blower mounts and plenum.
Intake plumbing
Intercooler
5th injector controller
Belt
Idler and Tensioner pulleys
Needed hardware

You supply:
M62 Supercharger

I have to say this is a pretty interesting idea. What kind of time frame are you looking at to get this thing into testing? I would love to see a vid and hear that whine (gotta love roots blowers). Very cool, please keep us posted on this.

Keeping you posted is what this thread is for, silly.... lol

My friend has his S/C mounted up already and is figuring the belt out. I am behind that, I have mounts built but the plenum isn't quite done.

I hope to have this on my car producing boost in August sometime, we will see. It's gonna take a little time because I have to go to my friends shop here in town to make the mounts and weld up the plenum. I don't have all the tools I need to make this thing.

I like the idea BUT, how are you going to retard the timing under BOOST, you have to pull timing out under a boost condidtion. How do I know, Im running a vortech with 18lbs in my 92 LX coupe car and I have to pull all the timing out under boost, ALL timing, under boost, the plug fires at ZERO degrees, at idle Im sitting at 19 degreee's advance. The VVT-I system advances and retards the timing based on Hydraulics (oil pressure), when you nail it the engine spins up creating more oil pressure thus more timing. The Escort has DDB2 but its a completely different fuel management system. OBD2 is standard but not all manufacturers implement it in the same way. Heres the ODB2 details for any one that cares.

Ctruss hopefully you guys have already done al lyour homework, Id love to see it work.

Adding a 5th injector may solve the fuel problem but then again, putting on larger fuel rails so you have plenty of volume at the rails for the stock injectors may work as well. The stock injectors will probably flow enough fuel for the horse power you are quoting. You dont need gobs of fuel pressure to make power, you need a lot of fuel (VOLUME) readily available whens its needed.
