Looks like @DOC_Race and OCD have more in store for us. I wonder how this will compare to the other ported heads available:
Doc Race ported cylinder head
- Thread starter doublespaces
- Start date
they arent that bad. Whats ridiculous is that metal valve covers compete with a head porting for price
I saw the flow numbers and yes our heads truly do sucked. No wonder you gain so much with porting and cams lol
Another option just so I don't have to deal with VAC is a win in my books.
If this includes an oversize valve option with all Ferrera components then I'm down. I have a need for 8500rpm for my end goals
Isn't the stock DME hard limited to 81xx RPM lol
What about the lifters?If this includes an oversize valve option with all Ferrera components then I'm down. I have a need for 8500rpm for my end goals
If that's true, then N54 hydraulic lifters are more robust than the M5x / S5x lifters that tap out right above 7000 rpm. Interesting.
The S5x is using way more complicated designs to accommodate variable valve lift. Something that the N54 doesn't have and isn't burdened with.
While I'm not sure what the N54's lifters are capable of, I've been down this road with the 4G63 back in the early 2000's. I over-ran those lifters and had to have custom machined solid lifters made. Been there before, it doesn't scare me
.
I agree, but I doubt it.
OCDWorks isn't inexpensive to start with and you are going to have their mark up on it and then Doc Race's mark up. Two hands in the kitty before it gets to the end customer vs. say ABR whom I assume does it all in house.
That being said more competition is better for the customer.
Is ABR still considered good, after what happened with them and Phuong's car on the MMP group? Honest question.
Standalones are like $3k+ IIRC? I might be looking into this avenue in the future when I swap in some Schrick cams, I should have a head capable of almost 9000rpm. What are the other benefits of a standalone ECU? Could it be coded for more security with port injection? (shuts down on misfire)
gonna PM you don't want to clutter the thread. If mods want the info out there let me know and I'll post it.
The main reason i would use one is dual clutch control.. further detail here
