Vmax Scart supercharger?
Turbo Mini Forums

i saw an advert for the Vmax kit using the eatonM45 charger from the bini it looks a pretty impressive piece of kit and i was wondering if anyone has any experience of it?

im going to be building a 1293 and am tempted by doing this modification (sorry its not a turbo im turning it more into forced induction minis forum! lol)

pretty sure there was a thread on this not long ago dude, stuart from VMAX was on here posting about it aswell. just do a search for it and you should find it.

8PortChris has the Vmax kit fitted to his 1380.

Yes he has :) :)
Do a search :) there's some pics

Here for the craic..

Supercharged Arden powered

I am in the process of building a blow through Eaton M45. Looking at the blower map, the charge starts getting very hot with the boost. The blower manages about 60% adiabatic efficiency at most.

I am putting my alternator (RX7) where V-Max has put his blower and the blower where the alternator is. This then blows through a Rover TD intercooler (There isn't much space left) and into a carb (which I haven't modified yet). The bracketry fouls the dizzy and so I have got rid of it (!!!!!) and will be using the "Megajolt" el-cheapo programmable ignition. (Haven't got the bits for that either). I am sticking with the grooved belts as per Bini Blower and am looking to make my own crank pully/trigger wheel myself (don't know what size yet).

Looking at the whole characteristics of the blower and what Vmax is up to, the 1380 might be the wise choice as too much boost will get get everything mega-hot. I am debating this myself having looked at what rate this happens at. From what I have gathered from the compressor map, I think 12PSI is pushing it. I heard one report that the intake pipe was condensing moisture out of the air....I suppose this was just adding to the charge heat.

1380 might be the go as I hear it is very impressive. But, the limits on heads are a push. Looking at 11cc pistons (don't think you can turn the bowls out at all) a 2cc head gasket. I think a 35CC chamber is required for an 8:1 (don't have my notebook handy). I'm aiming to mill my chambers out circular to match the piston bowl. If I can get close to 35cc, I will use a 1380 pistons, otherwise I will go 1293 at 15cc dish(18 is too much, I think).

My Bini blower cost me ?90 with 5 miles on it.

The amount of modifications I have had/have to do, I am not bothering with a test engine (which could be stupid/expensive) dictate it's going to be a while before I'm ready.

One thing which I did semi-consider was getting a Mazda Miata/Millenia supercharger from the states, they go for about $100 (plus shipping) and are twin screw design (about 80% adiabatic efficiency) can boost up to about 35psi if you need it. 1 litre pass and they are quite compact as well.

My logic with my head is to get the biggest chambers having a chat with a head designer, it appears that the chamber beak is not that important, so after milling out large circular chambers, I am going to assume as I am not running a turbo, I don't need the massive heat conduction of a fat exhaust valve, retained boss, so I am going to remove it like a race head, run big ports, and a big bore lagged LCB. (Curious why V-Max has chosen to us a freeflow with one of his designs). From what I gather, the exhaust should be sized the same as a 2L car !!!! I am going to use MG Metro sized quality valves with the 3 angle mod. Since I will be using a standard A+ crankshaft, I won't be revving the tits off it, so from the best of my judgement, I will be using a Piper Ph2 cam which looks a bit like a fast road 266 with more exhaust duration and lift. I reckon from my semi-informed hunch, it looks like the cam to use. I think I will be also running 1.3 rockers.

I'm looking for something with maximum torque and a 6500 rev limit, first seeing how a 2.76 (from a Auto Metro) goes with a 2.54 first gear.

The engine is all over the shed at the minute, I will tell you how I got on.

Stu+Pinch of Salt, as usual.

Bugger off, I'm getting there.

sounds a really interesting project hedgemonkey i think ill go with the vmax kit when the time comes around,
those bini superchargers are everywhere i worked for the company that does all the s works cylinder heads and we had so many of them lying around packed in boxes! so tempting to take one.

i am tempted to use just a 1275cc and rebuild it and then bolt the kit onto it aim for around 95bhp

It's not as easy as it looks. So far. I thought it would be a whack it on and go for it thing. If I wasn't on a personal challenge thing, I would buy the kit.

Bugger off, I'm getting there.

Would love to see pictures of how it's all coming together. The VMAX kit has always caught my eye. Might have to save up some worthless US dollars to buy it :)

My mate Johnathan here in Worthing has had his 1380 upped with a VMAX charger, goes like hot snot.

Hahahah...not just snot, but HOT snot. :)

Whats the power on a 1293 charger over a 1293 turbo both with the same spec ie cam carb pistons c/r

1293 Turbo mini

I don't think the Dodge Charger was ever offered with a 1293. Just teasin of course.

That's an interesting comparison. 1293cc engines with turbo and with the Eaton M45 Supercharger. Guess they'd have to be blowing the same boost then eh?
