can anybody with sc12 and sc14 tell me the dementions of it and also if anybody has just pics of the supercharger thanks

dude do a google search for SC14 or something, there's a page with dimensions on it, pretty easy to find. from memory they're roughly 30cm long, and 20-25 wide

also with the xtra injector bro - you dont need a aftermarket ecu to run them at all - alot of high 11 second cars use a hobbs switch, and just feed power / fuel hoses to the injector and hobbs switch. when the hobbs switch reaches its desired psi - it will then allow the injector to start pumping - a nice cheap alternative which does have its advantages and disadvantages. not getting off topic here. but with that twin throttle body setup the xtra injector setup on each cant be that bad at all considering that on a normal vl it would be a xtra injector trying to spread evenly to 6 cylinders, but in this case only needs to do 3 each instead which lowers the risk considerably. damn that was long lol

good thinking though, if you did just add one extra injector, it'd have a hard time spreading the mix evenly, the middle runners would recieve more fuel than cylinders 1 and 6 would for sure, not such a wonderful thing. twin throttle bodys with an injector in each would make it much better, but could stress the fuel pressure a little?

what should one look for if buying one

a blower? as little play in the vanes as possible, they should be nice n tight. if you can turn it, make sure it's nice and smooth. hard to tell condition really without opening it up, but they usually last for ages, the SC-14 is quite durable.

http://www.rodshop.com.au/superchargerb30.htm "We have been testing the kit on a VL Nissan and everything has proven 100% reliable and dyno runs have been performed with the below results (see graph to left). On a totally stock motor with only the decompression plate fitted an 80kw reading went to 110kw with no computer modifications. No other modifications have been tested." Some original photos have not been recovered yet.

thanks for that, might want to check the other pages of this thread though. this has already been shown.

Edit: I was in kind of a bad mood when I wrote that, sorry. But yeh, its not in the thread, and even if it was who am I hurting by posting it again? If you're gonna say it wastes bandwidth or it makes the post too long, you're hypocritical because you made a post to point that out, leading to me making this post...so we now have 3 unnecessary posts instead of one. Anyway, I wouldnt get the kit of CRS, @$2000 its a rip off imo. It does give people some ideas on how to set up a blower though and some idea on what gains an sc14 would give.

good point! looks as though that pic has been removed. yes i agree the CRS kit is a little expensive, particularly so in that it only uses and SC-14 which you can get for 250-300 bucks anyway. they appear to have modified the drive pulley on the blower to accept a Vee belt of the type used to drive your air-con compressor. then i believe (although it's hard to tell from the pics) they have just run it off the air con drive belt on the crank. that's exactly what i was planning to do with my setup, that pulley is roughly 16 cm in diameter, thus boosting around 8 or 9 psi i hope. the only tough part will be paying someone to modify the blower drive to accept that belt, might cost a bit in machining expenses. however i think this will be better in the long run in terms of belt slippage, i have decided to do this in preference to attaching another pulley to the power steering pump so that i can run more boost, without the slipping problems. just my 2c if anyone else is thinking of doing this. p.s. is that my car in your avatar? Some original photos have not been recovered yet.

That kind of supercharger would be usefull only for low end to medium torque. I bet that higher in the rpm range the sc14 would struggle since they are originally from a 1.8L engine.

agreed, that's why running a larger drive pulley with 200% blower overdrive would be needed. it will still struggle above 5000 i predict though, but then again if i was going for top end power i'd buy a turbo! or perhaps both.....

yeh and I've heard that the teflon coating inside the blower comes off at 10,000 rpm, so you cant spin them faster than that

SC14's are from a 2L engine

Yes, they are from a 2.0 Litre engine. But a better comparison is that they efficiently flow enough air for about 160Kw on the stock Toyota engine. Provided your power goal is about 160Kw it will work fine, the engine size does not really come into it. They will produce about this power level on just about any reasonably sized engine. What they will not do is produce much more power by turning them faster. A lot of guys have difficulty understanding this. The efficiency falls rapidly at higher blower RPM and higher boost levels. So driving it harder is not going to get you much extra power.

for all those who pm me looking for photos this link still exists http://au.msnusers.com/stromysworld

I know a guy that had one of those superchargers on a injected 5 litre holden motor (From a VP V8) in a old monaro *chuckle* He made me put a blow off valve on it and he reckons he loved it. I tried to tell him that you would have to seriously overdrive the charger to keep up with the v8, but that it would be hot air, but he didnt understand. All he saw was the jump in revs and supercharger sound when he blipped the throttle when he finally got it "going" Then last week he rang and said he got it dynotuned. I said "did the dyno guy laugh at you? " he said "yup." I said "did he make you take off the charger?" he said "yup." Dyno guy reckons the charger at full throttle and full revs, was actually holding BACK the v8. It was holding it back around 20kw. At full noise and throttle, the manifold pressure was around 4psi, and the temperature was 80 deg C. They took it off and straight away the motor made more power.

haha funny ****. Someone on another post said he used a plumback BOV with a sensor on the TPS. As soon as you lift ya foot the blower turns off, when you put ya foot down it turns on. How would one do this?

TPS signal wire would have to be tapped, it only measures full throttle and no throttle. once you had the signal wire, you'd hook that up to a relay of some sort controlling the blower power feed. not too hard, but i'd still prefer an on/off switch in the cabin.

yeh thats got me thinkin. I heard the blowers dont like to be engaged/disengaged at higher RPMs so haveing sumfin like that could shorter the life of the blower, or at least the clutch could it not??
