Post subject: | Please help me Supercharge |
Hi all. I've just purchased a second hand AMR300 Aisin Supercharger. I am planning on setting it up as blow through. The problem I have is that I don't know what pully ratios will give what boost. I have tried the Aisin site but could get no info there. Please any one who has delt with this before can you help me. ![]() |

By blow through, you mean "supercharger - carbie - engine"? All superchargers I have seen on Mini's are suck through ones, so "carbie - supercharger - engine". This also means you can use a standard type carbie, instead of a metro turbo type one (which is blow through). |

Post subject: | Blow through set up. |
I have a 35mm Weber which I was going to set up for blow thruogh (Supercharger-carbie-engine). The only reason I was planning on going this way is it's whats recomended in the Vizard book. Would it be better to set this up as suck through? Cost isn't the major concern, I'm more interested in performance. |

I've seen a weber in a suck through setup. You've gotta go putting special seals and stuff in a blow through carbie because of the boost. As for performance, i'm unsure if either has an advantage over the other? |

It's more a matter of preference I thought. Both can achieve good power but a blow through setup can be harder (Vizard said that the Janspeed Metro turbo setup was the first blow-through setup he had driven that had real power). Guess you way up the pros and cons of each design and decide - blow through you need special seals on the carbie and suck through you need a carbon seal on the supercharger (?? at least you do on a turbo) |

check out my page, http://www.cardomain.com/id/supercharged850 ..... is yours the same supercharger as mine??? If it IS the same, yours will have a 55mm pulley on it. You will require a 97mm pulley to produce the factory boost level of about 8psi. You can find an almost perfect pulley on a Nissan N13 Pulsar water pump. This pulley measures 94mm in diameter, and can be mounted over the mini's original water pump pulley, or you could modify it to fit the crankshaft.... This is what my supercharger came off, a Subaru Rex VX 660. Its a 4wd, 660cc, supercharged, micro car. Ugly yet cool..... This site has more info (in japanese) http://www.geocities.co.jp/SiliconValley-PaloAlto/3756/project/frame.htm The engine model can be either EN07Z ( thats - E N zero seven Z ) or EN07X. Below is a belt and pulley diagram for the engines. I hope your Japanese is up to scratch!!! ![]() If your supercharger is NOT the same as mine, ignore ALL of the above.... Enjoy *edit: picture links updated |

Brilliant ![]() It was your car in the cardomain sight that lead me to this sight. Yes I'm pretty darn sure it is the same so all your info is very helpful. Just wondering as I can't really tell for sure from the photo's if you've set up for suck or blow through. What sort of seal work did you have to get done on either the charger or carbie? Cheers |

i'll just reword a bit of my previous post so that there is no confusion.... Supercharger has a 55mm pulley. 97mm pulley is required to drive the supercharger's 55mm pulley so as to produce the standard 8psi. The same supercharger is also fitted to other Subarus, eg: Pleo, Vivio. My system is suck thru ( and still incomplete ), the seals are normal on the carby, carbon on both faces of the supercharger, normal on the inlet manifold. I did some measuring of my pulleys today and got a shock.... The N13 pulley isnt 97mm, but actually 86mm, so it would infact drive the s/c at under 6psi. Its still sufficient though.... The s/c drive pulley on my waterpump is 107mm, so the s/c would be driven at closer to 11psi. I am not sure where the 107mm pulley originates from. Here is a couple pics of the drive pulley setup, using the N13 86mm pulley over a standard mini water pump pulley.... ![]() ![]() ![]() ![]() |

oh, and also, did you know the AISIN supercharger also doubles as the AISIN washing machine water pump!!!! True! |

in the previous photos you can see the supercharger pulley being smaller than the water pump pulley. That s/c pulley would drive it at around 6psi. It can also be bolted to the waterpump. Below is a pic of the pulley i am currently using to drive it at 11psi. It is noticably larger than the water pump pulley, but i had to cut the centre out of it and WELD it to the water pump pulley, cos it did not fit. Lots of work to do this..... ![]() |

a webber carb can be used, but its a bit bulky for an already cramped setup.... you'll need a split pipe if you intend on using both sides of the 45. too bulky...... i know the kit you are referring to, i've seen it in action originally on a 998 .....the kit consists of the blower (larger than mine, off a toyota 4AG-ZE), a couple brackets and a couple pipes, but you would soon find there are many more things to pay for after that.... Its not a case of bolting it to a hot 1380 and away you go.... it requires a totally different cam, lower compression, modified distribuitor, etc etc.... the motor would need to be built to suit the blower. I would personally stick with an unboosted 1380, cos the cylinder walls are gonna be wafer thin. You'll break it easily with boost. The total cost would also be a bit crazy. For the same price you could fit a Suzuki G13B twin cam in it..... with more power ![]() p.s. i'm guessing i beeped while driving past??? Cos i do everyday around 2pm.... notice the green roadster in there???? ![]() |

What oil did you use in the AMR300 and how may cc's? I have one and just looking at mounting it on my 998. Thanks |

i think your running a completely different s/c to s/c850's setup, i think that aisin 300 is a small one, so 300cc per revolution vs (sc12)1200cc per revolution, might want to check that, i'm going weber 45 with mine, i was told that because its forced a bit of a ristriction on manifold isn't going to make a huge difference so i might be looking into a goose neck, its only to make installation a little easier, |
