pusherman Posted May 11, 2011 Share Posted May 11, 2011 option 2 sounds more suitible i think id rather run low boost and get to drive my car regularly, so is it big pulley or small pulley for less boost. Quote Link to comment Share on other sites More sharing options...
kpr Posted May 11, 2011 Share Posted May 11, 2011 was just example. but yeh better off to start with lowish boost. i realize its a bit of a knob since have to change pulleys to change boost. small on crank, big on supercharger will give you less boost. ran roughly 1 to 1 ratio, when had sc14 on my 4age. would run 7psi max. that was with big na cams. i would suspect at least 10psi on your average 1600. so you'd probably want t underdrive it a bit if wanting to go below 10psi. sc12 with a sc14 pulley would get you less boost than a straight sc14. can't remember what the deal was swapping the pulleys over tho Quote Link to comment Share on other sites More sharing options...
427carguy Posted May 21, 2011 Author Share Posted May 21, 2011 Thanks to the fucking earthquake iv only just got around to mocking my super charger up. Looks like its going to fit pretty well tho. Quote Link to comment Share on other sites More sharing options...
pusherman Posted May 21, 2011 Share Posted May 21, 2011 plenty of room there for it ay. looks like its going to work. my plan is mounting mine on the intake side, but looking at that putting it over the exhaust is probally best plus will leave room to get to dizzy when needed. im now thinking what carby im guna use im currently running twin dellortos but im thinking a holley jeted back so it doesnt flood the shit out of everything, would this work? what else would work?

RUNAMUCK Posted May 21, 2011 Share Posted May 21, 2011 Looking good Hogan. I'd definately suggest you consider header wrapping the top part of you headers, and foam lagging the supercharger discharge pipe then going over the foam with that pure aluminuim foil tape to keep the pipe from getting too hot as it crosses over the motor. Are you planning to run the 32/36, or a single sidedraft carb? im now thinking what carby im guna use im currently running twin dellortos but im thinking a holley jeted back so it doesnt flood the shit out of everything, would this work? what else would work? I run a holley on my s/c datto. It runs fine, and uses less fuel than it did with the 32/36 weber. Although to run properly, I had to do a few modifications to make the carb drawtrhough compatable.

keltik Posted May 22, 2011 Share Posted May 22, 2011 a few modifications to make the carb drawtrhough compatable. This is relevant to my interests for future possibilities Quote Link to comment Share on other sites More sharing options...
427carguy Posted May 22, 2011 Author Share Posted May 22, 2011 im going to run a draw through set up with a side draught carb, but i think it will be a bit of trial and era. Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted May 22, 2011 Share Posted May 22, 2011 a few modifications to make the carb drawtrhough compatable. This is relevant to my interests for future possibilities On a holley you need to externally reference the power valve(s). I also had to fit a small spring kit to my accelerator pump check needle to prevent the air speed through the venturi syphoning fuel out the discharge nozzles.

Jayesky Posted July 5, 2016 Share Posted July 5, 2016 Anyone have any more updates of these supercharger builds? Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted July 6, 2016 Share Posted July 6, 2016 Hogan got his esky running, But he never got it tuned properly. I sold my supercharger kit to a bloke who Is as keen as I was when I started out. I have two more blower set ups that i plan to build. SUPERCHARGED! because.if it doesn't have a belt, you're probably wearing a dress...... 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted July 6, 2016 Share Posted July 6, 2016 Why not run a single big SU carb? A 2 inch off a jag or something similar they can also handle blow thru duties if you decide later on you wanted an intercooler in there. I ran a supercharger off a lancia volumex on a triumph 2 litre 6 cylinder with mechanical injection made some gorgeous sounds when it ran right which was about 70% of its short life as a skid hack. 1 Quote Link to comment Share on other sites More sharing options...
Gaz Posted July 6, 2016 Share Posted July 6, 2016 Look into running 1500 rods (or pistons can't member which) to drop compression. Quote Link to comment Share on other sites More sharing options...
Jayesky Posted July 7, 2016 Share Posted July 7, 2016 Mines well underway at the moment. Iv got a sc14 from an estima and a dellorto 40mm side draught. Manifold for intake is being laser cut currently and will be underway with the supercharger mounts this weekend. Also managed to score me a high flow fuel pump that's a direct Bolt on replacement for factory which is a bonus 3 Quote Link to comment Share on other sites More sharing options...
Bangbug Posted July 7, 2016 Share Posted July 7, 2016 From a datsun 1200 website.... I thought they were non-crossflow, but I digress from digressing.Looks cool......... but that's a lot of compressed fuel/air mixture!!!!!!!I'd put in a blowUP valve in there.There is/was a chap in Waitoa, Waikato who had a flat track something maybe a Fiat, pretty sure it was a Fiat 4 cylinder.It was supercharged draw though that looked very built for purpose.His nickname was Nigger Crusher, though I'm not sure anyone actually called him that.They were different times the 90's.Wonder how much of a bastard a flame arrestor would be.... in conjunction with the blowUP valve.Happy tinkering.

kyteler Posted July 7, 2016 Share Posted July 7, 2016 They are non-crossflow, there's tape over the exhaust ports. 2 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted July 7, 2016 Share Posted July 7, 2016 Shit that's a tidy set up. What was the username of the guy with that? 1200.com used to.be my second home once upon a time. But I'm not sure I recall seeing that before. With the carb hung that far over to the side, the accelerator pump check needle Is gonna unseat, and the pump nozzles are gonna dribble.

HighLUX Posted July 7, 2016 Share Posted July 7, 2016 Thought you wanted to have the intake with fall to the engine to avoid pooling of fuel in the intake? Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted July 7, 2016 Share Posted July 7, 2016 It pays to over engineer the supercharger mounting bracketry Make em good and strong. Quote Link to comment Share on other sites More sharing options...
