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!

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.
