Supercharged mk1

[ausgolfer]

so if its not i might get a harop supercharger!!

Might not be a good idea, might put out too much boost for the Kjet to handle, I think a toybota charger is the go for your application. Cheap/reliable/etc

Superchargers don't just run one specific boost pressure.. It depends on the rotating speed (which in turn determines the output volume) compared to the CFM the engine will draw.

It would be a bit of a guess at what boost pressure it would run at 1:1 or with overdrive, but the manufacturer should be able to give you a ballpark figure for you engine capacity. If worse comes to worst you could underdrive it. I've seen that done a number of times before with good results.

PS.. I like superchargers..Glad to see someone not going the shmurbo route.

I made up mounts to fit a similar but larger toyota supercharger off a 2l engine on my 16v and calculated that running it at 2.2 times crank speed would acheive 1 bar or 14.7 psi boost. I still have the mounts for it! But i sold the charger... I have seen a very impressive yet simple setup using a charger directly ontop of a modified inlet manifold with a downdraft 40mm webber on it. The drive belt was run off the cam gear with another gear mounted to the front of the cam gear. With 7psi it made 150hp on a 1.8 with standard internals. Go for it!

I seen a similar setup like this using K-Jet.

Was available as a kit. The blower looked like a very small 6/71.

I'm bugger if I can remember the name!

Update!!!

Was a Autotech Magnacharger kit!!!!

I've got the article on it at the workshop still.. I'll scan it and post it if you like.

ok so what i'm going to do is whip out what parts i have (and the charger i have(...mount the charger and get it running with the motor...belts hooked up and all.

get an intercooler made up...spewing i missed out on stu's one. then measure up where all the pipes must lead and hook them up.

would it be better to run solid pipes or flexible ones? by my calculations this sc should run at 5-6psi...and hopefully make a difference

You should get about 20 to 30hp from that i'm guessing, with good mid range and great bottom end.

Flexable or solid.. It really doesn't matter that much, however you are better off running solid tube as much as you can, with a few flexable joints where you need them. That eliminates a lot of the chances of getting leaks.

a newer more efficient charger than a an old toyota roots style will most likely give more boost than a Kjet turbo system can take....unless you shell out for porsche kjet injection parts.

if you use a more efficient puffer, that just means you can use a smaller one or decrease the overdrive to match the boost pressure you want.

careful stu - your charger ID

stu, that charger you have is not a toyota model.

the toyota SC-12 (1200CC displacement per rev) and the SC-14 (1400CC disp/rev) are much larger (and made by toyota).

the supercharger you have posted pictures of is, as mollins pointed out, the AISIN AMR300. this supercharger is only 300CC displacement, and hence you will need to run a very large overdrive to make any boost (or even keep up with atmospheric pressure).

AISIN is part of FUJI heavy industries - who make subaru. the 'charger is from a 600cc viveo which was sold only in japan. there are a few kicking around - i once bought one on ebay.

since its got such a small displacement, it is unlikely to be of any use to you (unless you plan on downgrading to a small block 1.1l engine or something)

this is what i was getting at before!!! i never said it was a toyota charger...i had a sneaking suspicion it was an AMR300. i'm going to see what i can get off ebay and prob get a 4agze charger...that was off a 6 cylinder 2.0lt so that should be able to make some power

i am not sure how much bigger they are...i mean anything would be bigger than what i have

[abreut]

The 4AGZE one is the smaller of the 2 toyota superchargers. It is called an sc12 and it pumps 1.2l per revolution, the bigger one is the sc14 which pumps 1.4l per revolution. I recommend you get the bigger one (which was off a 2.0l 6 cyl crown, you can get them for $250 to $300 from jap wreckers/importers usually.

The crown motor only had about 127kw but it didn't use an intercooler and didn't run much boost. As an example I used one of these sc14 blowers on my old 2.0l 8v and got 112kw@wheels (so over 150hp @ wheels) at about 9psi. So that should give you an idea on what is easily achievable out of one of these.

sweeeet! thanks for the advice. i'm trying to find some for sale now

so how do you change the amount of boost on a supercharger?

and i will be running a cooler

different pulleys AFAIK

cooler means you should be able to pump a few more psi than without a cooler on std internals.
