Boost, Blow Or Freeflow.

[GJM85]

planning on the build of my 5k if i can ever find one. Browsing ebay there are currently 4 better than average forms of induction available.

 

1.Turbo prepped webber and manifold with sealed plennum

2.Centrifugal supercharger to suite standard k motor

3.Single sidedraft 40mm webber

4.Twin sidedraft 40mm webbers (also available in 45mm)

 

My intent, give a 5k a full build with the good gear but need to decide on induction before I do so. Any advice, pros and cons and estimated outputs would be much appreciated.

 

Cheers.

I'm a supercharger fan personally

looking to supercharge a 5k. seems to be the best bang for my buck whilst keeping a degree of originality.

Anyone know the ideal cam specs for blown k motor>?

I will be watching this thread, as i already have a 5 k with twin webbers, so i would love to have a turbo setup along with the webbers :dance:

well played but the blower i'm talking about will blow the skin right off it.

Jaygore, blowing through webers can be done and done well but is a tedious exercise. I can't really think of anyone doing that in aus, maybe a on alfa specialist.

 

As for supercharging a 5k, there are a few ways to do it. Mainly it comes down to an efi or carbie choice. Blown 5k's ate real torque monsters and plenty of fun. Kickn5k has a blown injected intercooler setup with a custom blower cam in his ke11, it makes just shy of 100kw at the wheels and sounds like a 20b crossed with a NASCAR. It's loads of fun and easy to go back to stock if ever needed.

 

Mind you, don't say no yo turbos, far more scope for improvement down the track if you feel the need and similar to setup etc.

Thats only half done at the moment. I need to add turbo info to that article yet.

 

 

 

Anyway, as theNobbler said don't discount turbos yet. Superchargers can destroy gearboxes just as quick as turbo (if not quicker because of reaching full torque quicker), it really just comes down to how you drive it.

 

As for cams with a SC. You want something pretty mild if not just a stock one. If you go too big the SC will hit full boost and you'll be suffering "cam lag" until it winds up a bit.
