sc12 intercooled suck through system??
Turbo Mini Forums

hi

I've got an sc12 supercharger for the 1100 engine im building, but im not sure whether to go with the kit available form ben in australia or to do something different and make it work as a blow through system using the metro turbo plenum and carb etc.
The main reason i'm looking into other methods other than the kit from australia is that it cant be used with an intercooler.
This got me thinking today and ive come up with a plan to use the australian kit and create a chrarge cooler for use with it.
The plan would be to remove one end of the inlet manifold, weld a small flange on and bolt on the charge cooler design shown below.





The idea being that the core is made up of lengths of brake pipe and screwed into the plate using brake pipe fittings.(obviously the pipes would need to be formed around the bolting points for the supercharger

i would be interested in your thoughts ands opinions (will it work??)

Looks interesting. I'll be ordering one of Ben's kits soon.

The only problem I can see with what you're planning there is space. The manifold for the carb comes of the back of the manifold and folds round where your red arrow is.

There's a good picture in Gr4h4ms build thread on mini adicts.

It might work better going in the top.

doubt itll work, not enough surface area will be passed over from the carb to inlet, especially at high rev's, the inlet charge wont be in contact with the cold parts long enough to effect a noticable change, imho ofcource. a modern thick ally heater core fed with cold water would be a better solution i'd think? though you will need to redesign that plenum pictured, as the charge would be very uneven.

as above really, sorry.

Intercooling a suck through setup is not a good idea. If the system is efficient, you'll have fuel condensing on the cooler and puddling in the plenum.

are you looking at mega boost? like 20psi if so I would look at a turbo.

7-11PSI mine works nicely. Ben has run water injection via the bung on the carb manifold.

My car has got about 60 ATW from a 998 and all bolt on.. anymore power and everything would need upgrading. for me it was power per £ or $ :0 plus if anything goes a 998 is only £50 so cheap power for the money.

Plus the guy that makes this kit is a top bloke you get a top service even with him being on the other side of the world.
They have been running this kit in AUs and NZ for a good few years now.
+ with the $ to £ conversion its a very good value kit and those manifolds are ceramic coated. So its down to how much power you want.. ultimate power turbo is the way to go but with any very high power engine you need the bank balance to match. Its not the price of the turbo conversion its have a strong engine to withstand the boost..
Car still puts a smile on my face and at a wife friendly price.

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

I couldn't agree with gr4h4m more. Ben is a top bloke. He always answers my stupid questions. His kit looks top quality and he will change small things for you.

For now, I'll be running the kit on a standaad 1275 block, stage 3 head with MG cam. I'll be looking for about 100 bananas at the wheels from 11 -12 PSi. Which is plenty for my first go at forced induction.

yea mine is awesome - runs very well, I just need a bit more fuel - it leans out a little now and then on standard fuel pump

You should be running an ellectric pump with a preasure regulator. You need a constant 3PSi.

I'll be using a SPi mini tank in mine.

yea i know - its on the cards, mini almost never gets driven so is not a problem at this stage

hi
apbellamy
what dia fuel lines will you be running? i guess you'll be running a fuel return aswell? not really thought about the fuelling for the supercharged motor but i guess it similar to the turbo setup but without the variable pressure regulator??

I run a standard tank with a 3 psi facet electric pump.

Gr4h4am are you running standard fuel lines aswell??

I'll be running new either 8 or 10mm each way (feed and return) between the SPi tank and a Metro Turbo fuel preasure regulator. I will either just leave the rising rate pipe open to air or blank it off.

As it's suck through the preasure coming through the carb is constant.

I've also got a spare SPi tank...

might be interested in your spare tank if youre thinking about selling it? how much would you be after?

yep std fuel lines with a filter and regulator

is 3psi enough? i was pricing pumps yesterday a 4-5 psi pump is about 15 dollars extra and am wondering if its worth it, is a regulator needed? Im going to have the engine out over winter to do the head, clutch and fuel system (and oil leaks) so am just getting everything together now

i too have a Spare SPI tank and lines if anyone else is interested.
