I am wanting to put on a 70cc Supercharger and to address the fuel needs I was going to make a new intake manifold to mount the chager to and remove all stock efi. After that i was going to put one injecter per cly. in the new manifold and run it all with a Mega Squirt controler. The charger i think will put out about 6-9Lb of boost. Does this sound about right? Has anyone used the Mega Squirt on a Zuki? Also how did Calmini mount and run there supergharger (Photos would be nice!!!)?
What boost psi? Any info would be MUCH APRESIATED!

I'm just about to start the graft of injector
bosses to run the MegaSquirt for boost
enrichment, however I was planning on
keeping the stock injection for non boosted
idle, cold start, and cruise speeds.

Cal-Mini addressed the extra fuel by using
a side draft carb, and dumping the EFI system.

If I were to supercharge instead of the turbo, I
would use a SC Thunderbird supercharger, as it
could be remotely mounted (within reason) and
you can use an intercooler with it, most supercharger
system seem to bolt right on top of the intake with
no intercooling at all.  6-9 PSI boost will perk up your
ride. I just finished a Turbo setuo on a sandrail today
let me tell you 200 HP in a 600 Lb car will peel your
eyelids open, holy crap what a ride  

I was going to mount a Subaru wrx intrcooler on top the motor with the wrx hood scoop. I know not as efficent of a setup but COOL! air comming from a snorkel through a air box, to the cooler then thro. body mabey a neon(55mm) then to the charger. Will it work or what??

The zuk would look dam cool with the scoop!!!

No that won't do any good, when the air is compressed
it gets hot, then it needs to go thru the intercooler, but
I do think the WRX hood scoop would look cool, you
should see mine with a scoop on the hood from a Nissan
300 ZX Turbo, and yes it is fully functioning, not a dummy
muscle bump like the Mitsu Eclipse had.

So the charger has to be on the exhast side then the cooler too the intake. also i am taking about the wrx scoop not the normal little scoop, the scoop brings in the air to  cool the cooler . The cooler will be mounted atop the motor not in front of the rad like yours.

Your last post was a little hard to follow.
Are you going to use a supercharger
or a turbocharger?

they both do the same thing, but opperate
in a different manner.

if you use a turbocharger it needs to be close
to the exhaust system as it is exhaust driven.
A supercharger is belt driven so it can be
mounted in any location with enough room and
a way to get a drivebelt off the engine and around
the pully on the charger.

you can put a hood scoop on for engine bay cooling
but the real reason too have one is to cool the
intake charge before it goes into the engine.

I have not seen how the WRX intercooler is mounted.
I did consider putting it over the engine too. in the end
I put it up front for best air flow.

I have a Supercharger roots type 70cc belt driven.
The scoop will be monted to the cooler not the hood so the air will be forced into the cooler not the motor compartment ( Ie shaker hood of the 70's) works and cool. 2 for 1 .

This is how the wrx is mounted

the cooler is monted horazontaly under the scoop flat to the hood

the idea is definately cool but i think you should mount the intercooler infront of th radiator itll cool better that way and be more efficiant

plus the hotter your air is coming into your combustion chamber the more gas youll need to run to avoid detonation

The cooler is for a WRX 200+hp and it cools that why would it not cool a sidekick? Just asking want to get the facts right before I buy the scoop and cooler used.

Top mount intercooling can work, but keep in mind the WRX is also using a flat four instead of an inline four so it has more room vertically (in theory anyway).  If you do run a top mount I/C, I would recommend putting a heat shield under it between the hot engine as the heat rising from the engine will significantly reduce the ability of the intercooler to cool your intake charge.   I think if you're running a 3" body lift you should be able to get it to fit though unless the core on the I/C is really thick (which is bad for efficiency anyway compared to a big one in the height and width dimensions but thin on the depth dimension).  Also keep in mind that you'll get better air flow into the cooler if the opening is pointed toward the windshield since that's aerodynamically a high pressure area and you can get the same airflow into the opening with much less drag that way.  

It seems wrong at first I know but look at a cowl induction hood as an example of why it actually works..  An easy rule of aerodynamic basics with stuff is that if you're moving in the direction of the slipstream along the surface of an object, anywhere the surface moves up into the airstream a high pressure occurs, anywhere that the surface moves down away from the slipstream a low pressure occurs.  Therefore the base of the windshield on any vehicle will always be a high pressure zone.  This is going to be fairly pronounced on something like a Trackick or Sammy with a relatively flat and nearly vertical windshield.

I would suggest maybe looking at a WRX style scoop but rather than buying one specifically for a WRX, spend a little time working with composites (fiberglass is fine for this) and make your own because I think you're going to want a bigger one than the one on a WRX is in terms of width and length in order to have it work very good.  (basically match it to the size of your I/C).

If you were running a centrifugal style supercharger like a Paxton then for all intents and purposes the intercooler setup would be about the same as you'd do it on a turbo.  If it's a Roots blower, I don't know how you could intercool that without a very elaborate custom intake.

Basically you'll have to make a rigid piece for the supercharger to attache to, then duct that output into your I/C and then back into your intake.  It can be done I'm sure but using a roots instead of a centrifugal is going to make it a very big project.

For mounting the injectors the easiest way to do it would be to just take the stock manifold drill it where you want the injectors at and then get some injector bosses welded to it.  That's actually a pretty minor deal compared to just getting the blower setup when you consider the amount of space under the hood with a roots blower.

Since you have it already, it's worth looking at seriously, but if it was a situation where you were looking to buy a supercharger I'd definitely go with a centrifugal over a roots in one of our rigs.

Tracker_GT, I agree a Front Mount I/C is generally better but space is a limitation on our rigs, (even worse if you have A/C since the condenser is already in front of the radiator.)  Then again if Alaska101's username is any indication of where he lives he probably doesn't need the A/C so that might give him the option.

OK, the boost output is controled by the pully
size, either on the engine or the blower, to make
a system work well, not totaly a ricer killer, but
a definite kick in the pants increase, limit the boost
to 4-5 psi and forget the intercooler, you should get
about 120 HP and a lot less headaches from the
fabrication. if you go with a little more it will be fine
but you have to listen for pinging and modify the fuel
or the boost to keep it under control, mind you there
is a point where no mater how much fuel you inject
you still will get some ping, then you need racegas
or alcohol, both of which have their own problems to
deal with, racegas |removethispart|@ 4-6 $ Gallon, and alcohol fuel
use rate at 1.5 times that of gasoline, small fuel tank
on the trucklet, availability as well as price  

just zip tie the dam intercooler to the outside of the grill!   you'll have all the air you will ever want.   lata stu

Oh you i'm trying to ruin you thread but i just have to say it.  don't forget to put a huge decal on the side that sez, supercharged or turbocharged  lata stu

Look on the bright side, if you didn't mind the zip-tie method you could probably get a big Isuzu NPR truck or Ford Super-Duty Intercooler to fit.  Those Ford ones are massive, 39" wide and about 24" tall.  They seem to go pretty cheap on ebay too usually.

I think Wildgoody is right, try and keep it simple. I've just been looking at the inlet manifold with a view to modifying one to take two sidedraught injectors but the manifold is a complex item with the main water channel running through it and some sort of emissions set up too. What I plan on doing now is to bore out the stock throttle body from 45mm to 50mm and remove the stock shower type injector as it will restrict the airflow. I'm going to make a 1" TB spacer and drill and tap it to take an injector. If I supercharge it at a later date I'll fit a second injector in the spacer to increase fuel flow.
