Anyone compared the skunk2/ HRD head to another one from maybe RLZ on a flow bench?

How does it compare? g00t ch1t?

 

i doubt it. don and i HAD the only P72 head in the country to my knowledge, even though there are a slew of PR3 heads out.

Call Skunk2, or go to their website, they have flow numbers posted on the PR3 head. Im sure its 290+CFMs

 

I saw the #'s on their website, but would prefer third party figures - as different benches read differently...

I'd expect close to 300cfm at .500 lift..... but it's throughout the range that I'm interested in as well... that and a good comparo of a top ported head...

 

RLZ beats those cfm numbers correct??

 

I understand what you are looking for Ken. My best advice would be to :
Measure the costs of a fully ported head from RLZ
Measure the costs of a CNC Head (PLUS CORE) from Skunk2
Figure out which one flows the best for your application
Talk to Don

good luck sir!

 

I've seen the HRD port and I've seen some of RLZ ports.

I would do RLZ for a smaller motor as Brad can tailor the head to your needs. (smaller than 2.0L and less than 12.5 CR).

On a big NA motor the HRD head is looks real good.
