another crazy idea
« on: June 23, 2007, 07:55:43 PM »
I have a 95 tracker with a 16V 5spd, and a supercharger off a 90ish thunderbird.  I also have one spare pulley on the front of the engine, so all I would have to do is fab up a mounting bracket and do a little plumbing.  with low boost I wouldnt need an intercooler.  because the tracker pulley is small, it wouldnt give me as much boost as the original application of the supercharger.  If the serpentine belt fits, meaning the grooves on the pulley are the same size and pitch, I think it would work. 

Question, how much boost could the stock ecu compensate for?

A smaller pulley gives you More boost than a larger pulley because it's spinning the supercharger faster.... But if you can get it to work, I say go for it, sounds awesome

supercharger??  won't that have to mount on the intake manifold?

smaller pulley on the crank, not the supercharger.  the circumference is about half of what the 3.8  crank pulley is

I'll put it where it fits and just run ducts.  youre right, the old roots type superchargers did  bolt to the intake, but this one has a duct in and out.

I don't think you understand.  A smaller pully on the crank will turn the supercharger FASTER.  Its just like a ten speed pedal bike.  Whenever you shift to the smaller sprocket you can pedal FASTER.  Also these small tracker engines are use to running 4000+ rpms on the highway...but if you can get it to work...AWESOME!!  ;D

A smaller crank pulley will turn the supercharger SLOWER.  Think of it like a ten speed bike, when the chain is on the bigger sprocket up front(i.e. the crank pulley), the sprocket on the wheel(i.e. the supercharger) will turn more revolutions in relation to the front sprocket. When the front sprocket is smaller, the sprocket on the wheel will not turn as many revolutions in relation to the front sprocket.  Or, think of it this way, you can calcualte your drive ratio by dividing the diameter of the crank pulley by the diameter of the supercharger pulley. The closer to a 1:1 ratio, the slower the supercharger will spin in relation to the crank pulley. Slower speed=less boost.

I concur - a smaller pulley on the crank will spin the supercharger SLOWER. A smaller pulley has less circumference and that means that less belt will be moved around it per crank revolution.

Crazy - not at all. Plenty of people here in NZ have done this to Vitaras  ;) I was actually talking to a friend about this only yesterday - he needs more power  >:D

I just got my turbo install done and with all the extra heat I make I wished I had done a supercharger instead!!! good luck

Sounds like a good idea to me. I'm not sure how well it will work with the standard pulley though. As I understand it the supercharger size and speed needs to be balanced to the amount of air flowing through it. If the airflow of the Track/Kick engine is less than the donor (most likely!) then you would need to spin the supercharger faster to gain an equivalent amount of boost.

I keep thinking about this for my new build but it would be a way off yet if I decide to do it. My new one has the 2.0 J20A engine and something like the SC12 (4AGZE) or SC 14 (1GGZE) superchargers used by Toyota can be picked up pretty cheaply. I like the idea of instant low down and linear power delivery plus they are clutched too.

all this talk about superchargers and turbos is makin me want to do it to my tracker to. how much do you think it will cost for a turbo?

   Not much if you hit up a junkyard and make your own exhaust manifold or modify a header.It realy isn't that tricky except for getting the fuel right.
