supercharger set ups

[nunit]

wondering if you guys could post some your supercharger set ups with specs im doing a little research on the idea and i cant find too much due to the turbo ranking first in forced induction any help and pics would be greatly appreciated.

I've seen Eaton setups, and the DLI kit a few times. I'm doing something a little different, using an IHI twin screw compressor with a T4.

there are some interestung builds...but ready to bolt on kits are not that cool. dli was kind of ok, but whay to expensive.
a did some supercharger setups, some for watercooled engines and my own vintage 36er supercharger engines.i am addicted in 36 .

it all depends on what you wont.
if you wont up to 130 hp, sell a AMR500 from aisin...these are out of the MA09 engines( i also have a holder so sell)
this is how my amr500 system look like.


kind of the same is possible with an sc12...also aisin but from a toyota. i didn't build an engine with this blower, but hte toyotaguys use them up to 250ps so its good for bigger engines.

at he enfd ther is also my 36er amr300 blower. i dont know how about the sc12 and 14 but the 300 and 500 are build with teflon impellers. i used them with E85 through the supercharger with no problems.
all the aisin blowers are good to 14 psi. the amr300 up to 20psi but with intercooler and a perfekt engine only up to 95hp.
at the end it depends on you what you like. if you have money go with "rotrex supercharger" tiny as hell + very efficiency.
eatons are really good with low boost but also can do 14and more boost, but i would not suck fuel through them if i could.


i just can say i could build every supercharger into a bug with cooling. but a turbocharger will ever be best if max. power is important. and for a supercharger it will be best to have higher compression and less boost.
the supercharger is a good link between N/A and turbo. drivable like a N/A without setting in of high power at one point .
but more power and tourque than the N/A ..for sure not that big like a turbo can do. i drive 15psi on a nearly stock 36hp engine at daily driver, idle like a clock at 500 rpm if the old 6vgenerator wasn't that bad. max power of stock engine was at 3400RPM now near 5000RPM.
her is an old video of the characteristic . bad handy sound. sorry.

supercharger are not a good option because there is not that much room in a bug so it is not that common.
i could write more and more about that but ask if you have questions.

thanks for the post very informative. i think im going to run a similar setup with the sc12 and the sidedraft ive got a 1776 already and while it runs well i want more torque once i get my taxes back ill hop on ordering parts andill be sure to post a build thread im currently in welding school so i have access to every type of welder and metal tool imaginable. ine thing im definitely looking at is megajolt for the ignition and possible water injection to keep it cool anyone sell megajolt kits for the type 1 from the power u described this sounds right up my alley im more about down low torque than maximum horsepower.

[my_medusa]

than its the right way to go.
full megasquirt will be open much more potential,..intercooled and and an.
but the setup like "joel" did can hold costs down and its easy to do.
in my eyes the sc12 is a bit huge for a 1776cc but not bad. it would be a just bigger torquer with 2.0-2,3l.
friends of mine from finnland have a projekt wich a 2,3l typ1 and the sc14

if you have questions about the sc12 setup try to contact joel from the aussi forum.

The original application for the SC12 blower was on a 1600cc Toyota engine, so the sizing should be OK for a similar displacement VW engine, no?

I bought one of eBay a while back, will eventually try to do something with it along the lines of Joel's setup, but probably with DIS at least so that I can get the blower to tuck down tighter to the engine case. Personally I'm a big fan of Roots type blowers for a low rpm driver type car. A previous car I owned was a Ford Thunderbird Super Coupe, that had a 3.8L V6 with an Eaton M90 blower. Rated for 330 lbs./ft. of torque at 2500 rpm ... with a few bolt ons it was putting down 340 torque at the wheels at 2700.

ive already got a ms computer but i dont know if it works i dont think i have the funds to do a supercharged and fuel injection conversion at this point i could do blow through webers but i like the simplicity of joels set up the dis would make for a cleaner install and more spot on timing once i get my funds together ill see if i can swing the fuel injection.

[my_medusa]

yes it was from a 1.6l engine. but had stock 170hp with low boost,higher rpm, intercooler, 16 valves, very high VE...
so with a 1776cc there is alot to do to get 170HP. and with joels setup "suck trough"....i like it too, beause its vintage and you can drive without boost by using the pedal softly....but with that setup you need alot of work to do to get that 170hp .
joel had about 80hp on his stock 1600cc and i think about 100hp on his 1776cc. so the supercharger is underdriven...good for the supercharger, but its not needed to have such a big blower then.
the blower can make 200 hp out of 2,3l easy on low rpm. with less work then to make 150 out of the 1776cc.
there is no problem to use it on a 1600 or 1776 it definitly will work but the blower can do alot of more.
1200cc per revolution...thats alot, a eaton M64 makes 1050cc per revolution and was on stock 2300cc mercedes engines with 190hp. alot of germans put them on 1,8l g60 engines and was wonderung that the performance was not much bedder than the g60...you don't need to think to big...but for sure you can

[Alexander_Monday]

Autorotor twin screw 3150, Megasquirt MSII, MegaJolt for ignition at first (already using, so 1 less thing to worry about)
then hand over ignition to MSII, water to air intercooler, Q45 MAF & throttle body, custom dual fan cooling shrouds.......
Slowly plodding forward. Make a piece, modify it, make another, etc...etc......
Hope to finally have it going this spring.

if you have questions about the sc12 setup try to contact joel from the aussi forum.

Im on here as well, just not real often

the SC12 will be fine upto id say mild 1916 at the most
it pumped 10psi into my 1776 fine, the only reason i took it off was the cam in that engine really didnt agree with the blower down low

i wouldnt run one over 10 psi without some form of water injection

the only other real problem i had with mine was it didnt fit under the decklid without standoffs which was fine in summer but through the cooler months the engine never got upto temp

[my_medusa]

hi joel..good to know that you are tere too. now you going subaru engine?is that right?
you told its good up to mild 1916cc thats not really true.
you forgott that you nearly spin your blower 1:1 that supercharger is minimum good up to 12000RPM
the toyota guys also go over 200hp. with a intercooler and efi i will say ok 20000cc is a usefull max. for that blower.
but you are right 10 psi is really a good boost level for this blower and this setup.


nunit want a tourquer low rpm if am i right.

and hallo mr. monday...impressive;)
this will be a pure drag engine right?how much cc?
kind of same setup that "rennkaefer" use on his 2,9 typ4 just different kind of blower. i would love to here the sound when its done...twinscrew will make some horror sound

how much boost you wont to push into it? am i right that the beltsystem is pk6? will this be enough?
i like your setup with the throttle befor supercharger, i think that will make it more drivable on the strip.
really good. keep on going.

[Alexander_Monday]

this will be a pure drag engine right?how much cc?

Midlife crisis weekend warrior . 2110cc in this incarnation.

how much boost you wont to push into it?

8PSI to start then go from there.

am i right that the beltsystem is pk6? will this be enough?

Yes pk6. 6 rib is what it used in a previous life on a V8, I have quite a variety of 6 rib pulleys, Jan-Erik at JM Tech didn't seem concerned, and I am going over budget soon, so that is what I am starting with.

So for a mild street 1600 or 1776, I wonder if it would be better to overdrive the AMR 500 unit, and possibly have too much heat buildup (maybe remedy that with a methanol injection setup), or go with an underdriven SC12? The smaller AMR 500 would certainly be easier to fit anyway.

@alexander_monday
sounds good to me, also with the pk6 in that boost level.
keep on going, like to see that thing on the track

@faster ed
at first your thinking is totally right.the amr500 will make a hand full more heat(maybe 5 F) and maybe needs 2-3 more hp when he is at a high rpm in compare to a sc12 on low rpm but same flow, depends strongly on the charts and what they will say but it also could be zero on both or a bit less. but i think it will take 2 more hp and 5 F when the supercharger is driven near its max. it all depends on how much you want.
i think too, that the amr500 is abit small for a 1776cc but it more depends on how much hp at which boost it makes.
boost is more a heat maker than the more rpm.for example eatons makes about 40 F more heat from 4000-14000rpm
but 70 F from 5-10psi. and small blower like the amr500 makes not so high jumps in heat on more rpm like bigger ones.
the smaller a supercharger the more efficency is possible in compare to a bigger of the same kind and often even on higher boost.and the smaller a roots is the earlier he can make boost.
in this case here its more important that you can close the bonnet
and when you think in this system...carb-->supercharger-->engine. low boost is needed because intercooling is not possible.
joel had about 80-100 hp at 10psi in this case i would use the amr500.
its not a judson so no heat pump and is not overdriven with 100hp.
i use it on a 1200cc. and it comes from a 1000cc engine.
i also used the amr300 an a 1200cc with water injection and so i can handle 15psi without a sec. oilcooler. just the original 36hp cooler.
don't forgett that typ1 have very bad volumetric efficency, so a stock 1600 makes 50hp. for deliver volume for 50 hp a amr500 just needs 4500 rpm. for 100hp 9000rpm ..the max is at 15000rpm. this is without needed power for the supercharger! a sc12 would for 100hp need about 3500rpm.....i never have seen flow charts for aisin supercharger, but eatons only start at 4000RPM. in real a sc12 will be driven nearly 1:1 an a 1776cc stock typ1 and with motor rpm of max. 5000-5500 you will lose abit in compare to a amr500....which is driven at about 13000 rpm at 5500.
but on a tourquer you mostly will not hit max rpm and there the smaller supercharger will be much more efficency...on a racer it would be different.
a supercharger should compare th tho output of the engine in NA. the original toyota 1.6 will not put out 50 hp as an sucke



so what did i want so say
ahh.....the amr500 doesn't make really much more heat than a sc12 on that engine
and it depends on what you want out of the system.

sorry for my bad english guys

[fast Ed]

Don't worry, your English is better than some people for whom it is supposed to be a first language.

With the distributor and maybe the mechanical fuel pump out of the way as well, I'm thinking that the SC12 could be mounted low enough to give adequate clearance without the engine cover standoffs.

How much power did you end up making with the 1200 topped by the AMR 300?
