I know there is all kinds of shit about these independently in the search, but I was wanting to know, specifically, considering my goal of 230hp(crank), which will give me the most useable power. I'm not sure how to word the question, but I'm wanting to know if, say, a full radius valve job will make the power curve broader, or just make the top end a little better?

I may be making a decision on this in the next week or so, so I don't want to go into this with the "this is the most expensive option, so it has to be the best" mentality. Are there benefits other than cost savings to getting the 5 angle? The 3 angle?

Thanks!

well there are 2 theorys

1 being the smoothest transition for airflow. meaning less turbulence when air is entering the chamber.

that would mean the full radius valve job would be best.

another theory is more for a turbo car but the more surface area that the valve seat has the more heat it can transfer outa the valve yet again would mean the full radius valve job would come out on top.

a poorly done full radius job wont out perform a normal 3/5

i cant remember which ford motor came witha full radius valve job from the factory and people actually made power by usgins a 3 or 5 angle valve job.

You can have it cheap, fast or good. Pick any two.

If you want it cheap and fast, it's not going to be good.
If you want it cheap and good, it's not going to be fast.
If you want it good and fast, it's not going to be cheap.

So you're saying that if I get it cheap and good, it won't be as fast then? Good info Bill! More please!

Tyipcally, going from a 3 angle to a 5 angle to a full radius valve job will increase flow at each step, but also cost progressively more.

In terms of what is better for mid range or top end, simply put the more "angles' the better flow, which should help everywhere but your main goal will be top end with that valve work.

It just becomes a matter of HP per $$$. More HP = more $$$.

Since you ae planning on 230hp crank, I'd save up some $$$ and go for the full radius work.

That and a lot of practice I think. What was that quote of your in English again sir? I went to FreeTranslation.com and it said something like "it all does broth" wtf kinda a quote is that? LOL.

WAIT! I FOUND IT!

tutto fa brodo. (L) from the Latin words tuttonomar, meaning "to lose," and fa Brodoconimous, the early Latin equivalent of "to Brian."

LOL. I'll be sure to wave to you as I pass you son.

I believe the translation is roughly: Every little bit helps.

Ah, that was the other translation.

Mike has it right.

"Tutto fa brodo" - equivalent to saying in english "every little bit helps"

It's one of those idiomatic expressions that are so common in Italian with some verbs (Fare being the verb in question, which means "to do" or "to make")

In Italian, literally it means "everything makes the broth." It's a saying which means all the ingredients you add to the broth of a soup helps make it better.

So, as it pertains to modifying your car, every little bit helps - "tutto fa brodo"

"Tutto fa brodo."
