isnt it better to have a lower comp ratio?

low comp and boost dont go together, it makes baby go boom boom

edit: stupid me.... your right low comp is good high comp is very bad. should think about things longer before i right crap.

Chances are the oil is still in there. It's supposed to last the life of the supercharger. You'll see on the back end (opposite the pulley end) There are a couple of bungs. One in the bottom, and one in the side. The bottom one is a drain, the side one has a dipstick on the bottom of it. The S/C12 off the 4AG-ZE has a yellow wingnut on the dip/fill bung, whereas the S/C14 just has a bolt hex on it. The oil is usually bought from toyota. It costs more than 30 year old scotch. They only take about 130 odd mls. Just unscrew your fill bung (With the blower vertical, IE over and under, rather than side by side) and see how much oil is on the dipstick. If you find that your blower is using oil, it's time to find a new blower. I've never heard of anyone rebuildoing one of there units. I'm not saying it can't be done, just that I don't know anyone who has.......

thanks ill look at the pully size and find out how big it is. also a14forced where did u get the oil dont care wat it costs if it needs it ill get it. 1200rallycar i have not got a carbi as yet but the bloke i bought the setup from is sending it to me by the looks of things it had a 32/36dgav on it why u ask??

what are you doing for a carby fella? did you get one with the kit?

They run a special toyota oil. It smells like silicon, and costs sh1tloads.

Have just put a sc14 on an A15 in my Morris Minor and found that the main problem was too much boost. I did have a 135mm pulley on the crankshaft which was putting out 11psi, now I am down to to 115mm pulley which seems better but still have to retard the timming as it was still pinging at full accetoration. May try a smaller pulley in the near future, I hear 4-6 pounds boost is about best.

if so wat oil would u use. ill take a look and see if there is one

There is oil in the gear case at the end, there is usually a screw in dipstick to check fill level.
