I saw it on ebay and drooled.. http://cgi.ebay.com/ebaymotors/ws/eB...sPageName=WDVW

1400cc/rev with electric clutch on the pully.

Switchable boost anyone? Let me know what you think ??

zbrown, You Have Started THE Trend!! You are a Rotary Legend in the making!

 

congrats....enjoy....

 

i thought a roots type SC was oil-less? i am also thinking of making this a project sometime in the near future, and am wondering about what type of SC to use. i hadn't thought about the MR2 blower. they are not as easy to find than the ones used on American made vehicles. i should start a thread on the best type of blower to use on a NA 7...

 

this must be the new craze around here...

nice buy btw

 

From a recent AutoSpeed article on superchargers...

The supercharger fitted to the 1G 2.0-litre straight-six is essentially a larger capacity version of the 4A-GZE’s SC12. Coded SC14, the 1G-GZE blower is the same width and height as the SC12 unit except it is 31cm long overall. The other major difference is the lack of an oil dipstick – the SC14 uses a conventional oil level inspection/filler plug. With the same 57mm OD outlet pipe but displacing 1420cc per revolution (220cc more than the 4A-GZE supercharger), the SC14 is fitted to the Japanese-market Toyota Crown, Chaser and several other models. Unlike the 4A-GZE, the supercharged 1G-GZE wasn’t equipped with an intercooler – this helps explain why it makes the same 125kW peak output as its little cousin. This is a better supercharger to pick if you want a little more power than the SC12 can provide – we guess that around 170kW would be a safe limit.

 

neato, and has the intake and outlet pipings too so you can just clamp onto those if they are near the right positions.

 

Cool find, good luck installing that thing..

 

I did some research online about it. when you shut off the clutch on it, it will automatically bypass so air can flow freely.. I can't wait till some getto honda pulls a rev at a light then i switch on a suprercharger and see there eyes fall.. ( i'll end up not racing just smiling. hehehe )

 

That's not how it works. It's only disconnected at very low load (idle, decel) to reduce parsitic losses. It is absolutely not meant to be left off while driving normally. You'd strangle the engine.

And nobody's going see or hear it when idling so all the Honda driver is going to see is you flicking a switch. Not exactly scary...

 

eh, I'll stick with my Vortech supercharger....

 

has anyone done a "how to" write up on installing a sc?

 

Reading the auction though it seems to be operated just like an AC clutch.

Those toyota supercharges have a nasty reputation for destroying the electronic clutches if you do it at anything over idle speed...

Not JUST chocking the engine, you will kill the clutch.

Just thought i'd add this to NZconvertibles info above.

 

It does, but that doesn't mean you can switch it on and off as you please, for the reasons WhiteFC and I have mentioned. In fact without an EMS with configurable outputs (so it can be switched in and out at the correct time), you'd probably just have to leave it engaged all the time.

 

you could make a bypass valve that opens up when you switch off the clutch, it wouldnt be hard at all, but you'd still be left with the killing the clutch problem.

 

A bypass vavle that would be able to facilitate the ammount of airflow required for a motor at WOT would be either, Expensive or Extremely Bulky

And you'd _still_ end up killing the clutch.......

Basically don't try and disenguage the blower at anything above idle RPM or Load that's all I have to say..

Oh, other than the fact that that you will most probably end up overdriveing this blower if you try to run any sort of decent power....
They're only just efficient on a 2ltr engine... now your putting it on a bigger engine and (presumably) trying too make a bit more power than the 1g-gze engines came with.
Probably not a brilliant idea... Might aswell just turbocharge it.. Whooops did I say that? Sorry... must've slipped out.



*edit: removed redundant term from above post, I should realy stop posting after i've had a few brews*

 

i would hope this 1400cc/rev would create some boost. even if i do leave it on all the time. there has already been some people that have gotten good boost from smaller displacment chargers..

 

i picked one up from a mercedes v6 engine that has the clutch.
the dimensions of the actual eaton m62 sc that is used in the mercedes are 11.5"x7"x5". i think it will fit better being its shorter.

 

this one looks interesting. what are your basic plans? follow Z's strategy?

 

Corky Bell's "Supercharged!" book, which is available from most online retailers. It doesn't cover rotary engine applications, but it is still a great book for non-engineers who want to know more about superchargers and installing a supercharger on an engine. Here is a review:

Just to add to this, I would like to point out that the blower in the Mad Max movie was fake. Please do not try to copy everything you see in movies.

for updated pics look around http://68.14.88.108:85 Beware dial-up users most are 2Mb or more.. I just finished a 'full' interier swap, which included making it a 2+2 (I know it's useless but this it not my everyday car, and the back seat makes it look more like a sleeper.) :evil: I have not cleaned or vacumed yet waiting untill I'm finished.. All the Charger brackets I made with just a air cut off tool, die grinder, and tourch. The tubing is aluminum tubing that I got off a Saab Turbo, along with the botch air bypass valve. The one peice of tubing right after the MAF is gavinized steel because of the welding.. (No access to TIG, Just MIG) I will keep updating about once a week or so.. Wish me luck Guys...

 

those pictures are waaay too big. theyre nearly twice the size of the screen. do you not have a way to shrink em?

 

yes i do. but is it not nice to see every detail?

 

How much boost are you planning on acheiving? Wouldn't it have been a better idea to aim for a 2.6-3l charger, instead of the smaller?

(Edit...Remove off topic)

 

I'm looking at the brakets that you fabricated... They look a little whimpy. What keeps the unit from moving 'front-2-back'?
