SO, will the custom head flow Lots and Lots and Lots of air, or more approaching 2 metric crap loads?

I continue to enjoy this thread and the ideas it presents to the community as a whole...

Can't wait to see the outcome...

I put a stock one on a bench 3 or 4 years ago when I was working on an 8v. I didn't do a complete 'full on test' but the numbers were impressive - 300cfm is quite possible.

I have played around with 16v heads that have been flowed by the experts and the numbers are quite impressive.

Not sure how you do a "full on test" but I found much better numbers

Chris White

The bench I use is computerized and runs a series of tests at different vlave openings. I didn't run the full test and I also did not make a custom air horn...so it wasn't a 'real' test.

And yes, I would belive there is a lot of potential in the head...other wise I wouldn't be playing with them! Unfortunatly PCA club racing also feels that way and has assigned a 20% 'handicap' to the 16v vs the 8v.

Series of tests?

Ive seen with you anything is a possibility.
What sort of intake system are you planning. ITB's ?

Will this motor be built as a 48hr limited life motor, or something more dependable?

[QUOTE=evil 944t;6933259]You can program it to test at as many specified valve openings as you want. Getting it to flow as small openings is as important as max flow at max openings. Flow as small openings will tell you more about valve seat and port design around the valve area.

[QUOTE=Chris White;6933321] So, Basically the same "tests" you normally perform on a flowbench but the computer does it for you. Yes, seeing I have flowed every Porsche head for our cars, I'm well aware of how to test a head and what to look for.

It will have ITB's. It will have a limited life span on some parts. It is high revving so, some parts will have to be inspected often.

[QUOTE=evil 944t;6933354]Yep, push the button and it does the rest....
I figured you knew about head testing...just tossing some info out there for the rest of the folks! Some people get fixated on the max lift flow numbers...

[QUOTE=Chris White;6933455]I'll have you know, there will be no technical content on my thread. Please keep it to a minimum or start your own thread

How much power do you expect to see all motor ?
What size turbo are you thinking
and is this going in the red car..

[QUOTE=evil 944t;6933585]OK, which sucks more - a stock 16v head or head from a $1k hooker...

$1k for some head better make you unable to move for a week cuz ur still goin

I wish good head was that cheap here, amazing head work which Chris has seen first hand out of Montreal requires "carte blanche" on time and cost.... Results are definitely worth it if cost isn't a deciding factor
