So has any of you used the eaton m45 kit then? i would like to get a view of the two kits and what sort of problems and performance you have gotten from them.

 

thanks

Ive got the vmax eaton kit, main inlet situation is rubbish. If I had my time again I wouldnt have it, now looking for some alternative. Other people have moved away from them too.

Using a hif44 carb on it, by the way.

i really like the look of the sc12 kit but there is very little information about them and even less about the results people have had. whats putting me off the sc12 kit is trying to get the charger.... 

[Gr4h4m]

As the kit for the sc12 is made in Aus, there are less people here running them. I was the first in the uk. Search on ausmini.com and there is loads of info. If you create an account on ausmini Pm user 92, be who makes the kit he will tell you everything you need to know.
I had a build thread on my local club forum but the site was closed down so it's all gone.

Here is a very old pic of the engine, sc12 kit and a 38mm bit carb, but you can use a hif, the inlet is much much shorter.

I have been looking at sc12 supercharger kit.
I like it.
What bhp do you think I would get out of it on my engine?
my engine spec is Rob Walker 1293,stage 3 head, megajolt, turbo clutch, piper 270 cam.
At the moment it is 81bhp at the wheels.

Times it by 1.4

I make more ATW on my 1060 that you do with your 1293 however, on a suck through system the ceiling is about the 130-140 mark (At the fly). I say this as I haven't seen anyone publish higher figures...

 

No my 998 has been developed a little, in that I have a cam that works well and the inlet is well matched in terms of throttle body size, I run water injection, etc.

 

Overall simple stuff as there is a load of data on peoples spec and what works well, on the Ausmini forum or from Ben the builder of the kit. Sounds like you have a good base but I guess you might need to do some work to lower your CR and if you can't get it from the head new pistons will be an expensive upgrade, and it won't be a bolt on kit....

I spoke to Graham Russell, who grinds the cams for Calver, about the sc12 kit his response was..

 

" they just dont produce the power they should".....he also went onto talk about how he put one on the dyno, then got onto the maker and quized him about the lack of power, the maker said that his dyno must be out of whack..etc..etc..If Graham cant make one work, then there are not many who can. The sc12 will work, but it seems the pully size is the issue.

 

Also, he doesnt like the way the some kits run the belts over the harmonic balancer..

I'm not sure anything in this post is helpful. You clearly haven't run the kit.

You can get what ever size pulley you want to run boost from 7-12 psi, anything over 12 psi is out of the range that is efficient on the charger.

I haven't seen a widely produced kit what doesn't run the belt from the crank. The eaton, sc12, sprintex kits all run from the crank pulley.

The suck through the power ceiling of all of the kits is around the 130-140 mark. I will say my small bore produces some healthily power, and did out of the box. Over the years I have made it more efficient.

So when the kit originally went on, my car had 33 bhp ATW, I bolted the kit on and with retarding the ignition still using the dizzy, having a custom needle made plus I had a few cc's put in the head to reduce the cr but no other changes it went to 61 bhp ATW, on and engine built in 1969. Now that to me was a big power jump for a bolt on kit. I don't recommend running the kit on a dizzy and should have gone straight to the mapped ignition.

I will say one thing about the sc12 over the eaton, I haven't lost any rotor coating and I've been running the kit since 2007.

The truth about all superchargers esp in the suck form is they will never be as efficient as an turbo when using an intercooler. We just need to get a turbo kit that you can buy as a ready made bolt on without needing bulk head mods and I might give one a go.

I sorry but I can't stand posts that are just I don't like bla, bla, bla when people clearly haven't run the kit, it's just not fair on the readers.

hi quick few questions

 

what cooling modifications have you had to make?.... im presuming there must be some 

 

And would the sc12 kit work with a servo brake system? or would the servo be in the way of mounting the carb?

 

thanks

Hi I run a 2 core rad from minispares and a two blade fan. But then I had to run these when I started to mod the car before I bolted the charger on.

It has a port on the inlet manifold to run a servo but I'm not sure how the fit? You are best to ask the bloke that makes the kit or have a look on ausmini.com
The bloke that makes the kit is called Ben and his ausmini username is 92, he is a very helpful chappy, I would guess someone on ausmini will run a servo mini

[mattywood]

92 on ausmini also makes a kit to use the sprintex supercharger which I am told is much better than the sc12.

[Grahamxx]

100 bhp and forced induction is easily achievable without too much of a high spec. decent head, cam and some forced induction 10 psi and you should hit 100 easily 

I'm interested in your power figures here. I've had my supercharged mini on 2 different rolling roads and only 93bhp at the wheels was achieved, I've made everything correctly, smoothed and purges all the welded joints for better flow, boost is 10psi, but what are you doing to get 100bhp at the wheels? are you using a carb or fuel injections?? This isn't a dig, just interested......

Does anyone in the UK import these Sprintex kits? And is there any experience/information available about running these.

They use these superchargers. a 150 I think. http://www.sprintex..../superchargers/ then you need the kit from 92 on ausmini
