The results of the acceleration of stage 3 cams at 11-12000rpms with stock rocker arms. As we thought, the stock rocker arms is <11000 rpm capable and below 4.5G accel. We test it to these rpms again, and we couldnt finish even the dyno. We will put our billet rocker arms and continue the test to 12000rpms.

Love watching this thread. The stuff you do and work on is insane!

Building ultimate stock 4g63 race heads. Titanium valves, beryllium valve seats, hand blended finish work, flow test / velocity feet-set / x-ray / pulsed checked. From brand new castings ready for race.


Stage 4 pics after vacations, u want believe your eyes.
I have so many parts to show u and i have no time.

After vacations we have:

stage 4 cylinder head
custom Wrc/lm intake manifolds single and dual throtle +1000hp/2000hp 12.000rpms
Custom billet cylinder head
2500hp setup for 4g63 engine
Race exhaust manifolds - collectors from 316/inconel/Ti
11-19blade compressor wheels
sequential gearbox
padleshift systems
our ecu system
2500hp bolt on fuel system
our new understroked 4g63 1889cc high rev high output engine methanol project.

Airplane is coming and I haven’t even packed my bags. (i wish i had a dyno there)
Have nice holidays

Wow, beautiful.

 

I gotta wonder, this head and cam work obviously makes huge power at lower boost levels when the turbo has ample airflow capacity.

But does it really gain much once you start pushing the airflow limits of a given turbo?

Or is the idea simply to put a bigger turbo on there to keep up with the new engine flow capability and just keep shifting the powerband to the right?

Funny how Extreme Tuners was getting bashed to hell until they starting showing us pictures of shiny car parts lol.

 

03whitegsr. making engine efficiency gains everywhere no matter boost or turbo.
for every engine there is a purpose, and specialy ratio intake to exshaust we make or VE.

stiguykiev. there is no nation or diferent places. there is only one join us. passion for tuning.

 

What kind of "normal" parts do you guys offer for us mere mortals? The guys that can't afford berriliyum and titanium for engine internals. Stuff that's still better then the average, but not what is in some of the pictures on here.

 

the stage 2 cast cams are around 1000$, and can make 550whp on a stock evo 8(9) turbo...
enought for you mere mortals?

 

But isn't that 550whp on a like 13:1 compression engine?

 

To run the valve acceleration rates that Spryos does on these cylinder heads, he needs very light valves (Ti), which require Copper Beryllium seats, which don't last very long. Furthermore you'll need some serious rocker arms, & solid lash adjusters. I think the key difference here is that he's making RACE parts for RACE cars. Not better than OEM parts for people who drive their cars to work and back.

I'd love to put his cylinder head on my engine... the question is can I afford it.

 

Sure you can!

 

Spryos,
how much for a set of your cams that retain MIVEC functionality on the Evo 9's?

I'll be using +1mm stainless intake valves & Inconel exhaust valves, Kiggly valve springs & retainers, and currently factory lash adjusters and followers.

I currently have a set of FP4R's that I'm taking out and I'm looking for something on the order of S3's or FP5R's to put in.
