Good info Doug!!

Those numbers suck though!

 

[PSDPlayer]

Yeah. The ported numbers are better, but those numbers are my secret. I paid 318 dollars to get the stock vs ported with stock valves and valve job. So I gave you the 159 dollar stock numbers for free.

 

[Hamilton Cams]

Doesn't give you a lot to work with. However I'm all about somebody making power with stuff that shouldn't. That is what it's all about!

CFM @ what PSI?

 

[UNBROKEN]

This is a tech forum....leave the bullsh!t out of it.

 

[Robts]

Richard.....Just having a little fun with Doug....He is so senstive about things

 

[GRotman]

CFM @ what PSI?

28'' of vacuum.

Sorry Richard , wasn't trying to clutter Doug's thread with bull****.
just having a little fun.

So what lift are the stock cams at?

 

[PSDPlayer]

.2296 times 1.40. Or something like that. .32144 inches.

I know a good flow number on a ported intake is almost 200 @ .500 lift, anyone know what a good flow number is for the exhaust side?

 

[PSDPlayer]

A wee little bit of porting got 142 at .600.

 

[hpprose]

When I installed my heads, I only got the intake side numbers. Didn't even think to ask about the exhaust....

 

[PSDPlayer]

Occasionally those are important on vehicles with power adders driven by the exhaust.

We just ported my head and did a sweet valve job. I wish I would have known my new turbos were going to take so long. I would have loved to figure out the new flow numbers.

Why did you skip that step?

 

[Wrightman]

Why did you skip that step?

Because we were in a hurry to get it back together and then other things held us up. Basically we're retarded.

 

[hpprose]

If you are retarted, so am I. Did the same thing

 

[Scooter's Roofing]

probably because he wanted to get the truck together ASAP

Question(s)

Ok so how was this test done?(Like in lab somwhere, or how?)

Were the lift number generated off a stock cam?

How do these compare to say a Duramax or Cummins?
