Supercharged mk1

[ausgolfer]

well the toyota runs one with that charger...... but might be able to get away with it. Still got the issue with the changing of the fuel and ignition stuff to handle boost.

yeh true. so what would i change? i'm thinking of going electronic ignition if that would help.

[thestu]

so like this....

but would i need a BOV or a valve of some sort...because when the throttle snaps shut where does the vacuum go?

[DVR68U]

yeah like that pic, ,you can put the bov after the intercooler. or maybe even before it . and it will still be under boost when the throttle shuts .

its off a 4AGZE motor yeh. its fair small can run up to 6psi i think. thats ok high revas wouldn't make much power anyway...stop making power about 5,800
anyway

Are you sure its from a 4agze motor? that looks like the smaller 300cc AISIN from a subaru vivio. check for dimensions here

Don't these things usually have an electric clutch?

You could wire it to turn off the blower when the throttle's closed or turn it on at full throttle.

The Jaycar HEI kit supports boost retard and can switch between two advance profiles from a switch on the dash.

the sc12 and sc14 from the toyota have the electric clutch.
Only problem is that i suspect that the charger that stu has is neither of these and infact an amr300 (which does not have a clutch) therefore a pressure bleed at closed throttle would be needed.

good luck with this one, part of me wishes i had have gone ahead with supercharging the 2e (using an sc14), but we cant always have things both ways haha
be interesting to see how this one goes

Yo thestu, very interesting idea here. I'm doing pretty much the same thing to my b1 passat. same type of supercharger but mine has the clutch on it. Not using the k-jet tronic system either. Just going to blow it through a dcoe. I'd like to discuss more indepth how your mounting it and what your doing with your crank pulley. I have an ADZ 1.8L in my beast so i'm think about running the stock belt system for that motor or to do something similar to you. Hope to hear from you, feel free to ask some forced induction questions, i know a bit about it as a mechanic.

cheers mate! i would love to learn a lot more about these things! like wether i have to run a bov or not. i will take some photos of the pulley that was made up also i need to know what some of the lines coming out of it are...any ideas? i shall take some more pics tomoz!

nah its constantly working. i am trying to find out exactly what it is...I have been searching and its not off a 4AGZE motor. io thought maybe it was one of the chargers off a nissan march but its bigger than those. i shall keep endeavoring to find out more.

[Preen59]

6 PSI should be OK without a cooler.. From what i've heard those puffers will do about 12 PSI before the bearings decide that they've had enough... Really, it just depends on how much over drive you're game to give it!

[vanders87]

Well I can tell you quite confidently you will be requiring a BOV. On overun your charger will still be producing boost so you need to waste it otherwise **** will hit the fan. I'll get you some more information on what you need to fit ect.

cheers mate. i'm still trying to find out what charger it is. i'm gunna find the model number tomoz and starting trying to fins specs

[McCosker]

hmmmmm, so if i were to try this with a carb setup i could just go ,

Carb --> S/C --> intake manifold/motor

Right?

with a setup like this i wouldnt be able to have a IC due to the fuel being put in the mix before its heated in the S/C. Also there would be no way i could run a blow off.
So who has done/seen a setup like this work well?

Im expecting to see alot more supercharged Mk1's after this thread is done.

[thestu]

ok so i can't find ant numbers on the sc!!! i think its an amr300 but if it is then there is no point using it!! because it doesn't put out enough to even wink at! so if its not i might get a harop supercharger!!
