Rookie Posted January 17, 2013 Share Posted January 17, 2013 It might be that your return spring isn't strong enough to close the throttle properly with the boost? Quote Link to comment Share on other sites More sharing options...
mark105 Posted January 17, 2013 Author Share Posted January 17, 2013 That is something Markku mentioned also and is entirely a possibility. So will need to look into that. Also what oil do you put into these super chargers? As i should have checked it but didnt and it looks to be empty. Is there some cheaper just gear oil i can put in it as opposed to the super expensive stuff i havent seen but been told about. Quote Link to comment Share on other sites More sharing options...
KIRK Posted January 17, 2013 Share Posted January 17, 2013 canola oil Quote Link to comment Share on other sites More sharing options...
Rookie Posted January 17, 2013 Share Posted January 17, 2013 Apparently you should use a light weight oil, but I dunno, seeings as it is a small sc12 you could use the oil they recommend for that. Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted January 17, 2013 Share Posted January 17, 2013 Just thinking- from memory I think in my shed iv got a small bov. Ur welcome to it if wanted ( just adjust spring pressure and use it as boost release valve with no actuation hose on the top Quote Link to comment Share on other sites More sharing options...
Yowzer Posted January 17, 2013 Share Posted January 17, 2013 The toyota supercharger oil is probably the type you want, but that shit ain't cheap. Apparently you can get the HSV stuff from Holden which is essentially the same stuff but way cheaper. Otherwise some 0W30 diesel oil.

Rookie Posted January 18, 2013 Share Posted January 18, 2013 ETA to burnouts? Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted January 18, 2013 Share Posted January 18, 2013 I may have some of the toyota blower oil. (As may a friend who onsold his blower.) It's very odd stuff. It feels very funny between your fingers, and has a very strong silicon rubber smell. Try find out how much of it you need. Is your carby a dashpot type carb? If it is, and the dashpot isn't returning, you'll be getting a very rich condition indeed. 20psi wont hurt when you convert to methanol. Once it's ride-able, take it for a hard boost, and do a full throttle engine cut to get a true handle on mixtures under load. The scooter guys call it doing a plug chop.

mark105 Posted January 18, 2013 Author Share Posted January 18, 2013 I dont think it is a dashpot type carb. At a guess it is a 35mm mikuni bike carb with the big round slide and spring to push it down. I dont think it will hit 20 PSI when you see the video it comes close but is still at about 17 or 18 PSI and im thinking that will be its limit. So it will be fine. Plug chop sounds good, will make sure to give that a hoon when its going, ETA till burnouts im not sure, this weekend maybe but have got heaps on also so will see.

KIRK Posted January 18, 2013 Share Posted January 18, 2013 those the valfs making that clatter or just video + garage weird noise? take off inspection plate/breather and see if the ends of stem are worn on angle. they get like that when guide is worn I think and sound way clatter spec. this Tecumseh I had was like that. intake valve slopping around all over the place and it also did that thing like yours when it would keep reving when throttle closed.

mark105 Posted January 18, 2013 Author Share Posted January 18, 2013 yeah i think it is rattly valves but has never run on till now i have slapped boost up it. Im thinking it is the carb still causing high idle. Quote Link to comment Share on other sites More sharing options...
