Head upgrades

[losh1971]

I don't think it quite works like that. I know an SC sucks some power to drive it, to create extra power. Can't remember if an SC uses 25% of it gains to actually drive it but it's something like that. More load on the engine means less economy.

one would think logically that with turbo/supercharger = more air = more fuel = ratsheet economy obviously

A turbocharger uses waste heat to spin the compressor so at low rpm you actually get a pumping gain.

It's clear your mind is made up with the head work so go that way.

As for not having the skills you've proven you have decent mechanical understanding so don't undercut yourself.

I did a turbo kit on my inline 6 falcon when I was 20 after only having changed oil in a car prior. I just jumped on forums reading and asking questions just as you already do.

But if you want heads done then do then and dont worry if people keen suggesting engine swaps. Same deal with a 304 and everyone harping on LS swaps. I never will.

I think Losh needs to just drop a 5L V8 in the old girl and stop trying to destroy the V6 with extra horsepower, save going bigger every few months.

I love the Holden V8 as opposed to LS. They have a unique sound with the right set up. I've been told fit V8 and bin the V6 but like you say if you're happy with what you have, then why not stick with it? V8 would be nice but unless it's factory fitted it works out cheaper to buy a whole new car with one already fitted than mess around pulling 6 and fitting an 8.

V8s have their set of problems and retrofitting is a costly exercise. I'm happy with what I have and I find it rather fun increasing the HP of the V6.

Long as your internal parts are upgraded as well or over time it will self destruct.

Yep and like I said already, I have have new, stronger timing gear, both crank bearings new new stronger rockers and will have fresh heads. The stock piston handle mild boost ok and I can only assume they are in good nic because I only go through 1/2 a litre if that of oil every 5k change. Be nice to replace cam bearings but no one here AFAIK can do that with the engine in. It
would have to go to the machine shop for such a job.

Would solve the water pump issue plus more torque at the same time = win haha!

Nah just add boost losh.
Like I said whatever your graph looks like add boost on that setup and it'll look identicle just further up on the power scale.
