CAM lift and duration

For anyone who wants more detailed information on how camshaft parameters affect the way engines work:

I'm still reading this, this article is either confirming or teaching me stuff, so I thought I'd spread the knowledge around =)

This link is for people who aren't up with the acronyms / terms

Also the factors of load, and fuel makes engines perform differently.

What I'm thinking of doing, but I'm not going to do this until I'm financially settled, so this will probably happen around 2010 =)

Increase compression to at least 11:1 (12:1) if possible.
Replace Rocker arms to have high ratios and retool cams to suit
Titanium Conrods and rebalanced, knife-edged crankshaft.
Replace all small cast iron components to billet steel.
Raise rev limit to 12k rpm with the appropriate cams =)

*smiles* I'm gonna be annoyed if anyone copies this and pulls it off before I do =)
Mind you, they'd have to be rich to blow this sort of money when they can just turbo it =)

er raising the compression is already on my shopping list...

its either that or put a hairdryer on it.........

haven't decided which way to go yet still trying to do NA mods that don't cost a fortune but problem is i'm running out of options....

So are we expecting the full job from UAS anything soon?
All the uprated engine internals to keep the car NA and mabe even oversized pistons to increase capacity?

yep...

going to take some time though...

details have gone off to a race cam builder for analysis...

i'm sure we can make gains...

one thing though is i'm going to run them in my car for a few months first to make sure there are no design faults and other car's don't have their internals broken...

a brake upgrade kit will be out first... still deciding exactly how to build the kit but it will be a lot easier than the CAM's...

Cool! I'll definitely be waiting for it! What sort of parts will be developed?
A detailed breakdown will be good, plus of cos...the $$$.
I am in Singapore and will need to freight it in.
