Every now and then I come across something truly impressive. This represents some of the work of Extreme Tuners in Athens, Greece, and the name is no joke. Pushing limits requires funds and skill, and these guys have both. All they do is build and tune engines. The entire lengthy discussion can be found here (http://forums.evolutionm.net/evo-dyn...ne-2007-a.html), but unless you feel like reading quite a few pages of posts, I'll post the highlights here.

FWIW, this is some of what they've done:

2006 - N/A ford cosworth 4cylinder 16v engine 119cui: 416hp -11,900rpms
2007 - Ford cosworth 4cylinder 16v Turbo engine 120cui: 1280hp 47psi (custom triple ball bearing 80mm turbo 119lbs/min)
2007 – Mitsubishi Evo 8 4g63 4cylinder 16v Turbo engine: 1416hp – 57psi (custom quad ball bearing 82mm turbo 132lbs/min)

So, getting 700whp/L from 2.0L @ 8500rpm is no small feat, but what do you need if you get bored and want to shoot for 2000whp?


Cast Garrett compressor wheels (right) tend to come apart above 50 psi. CNC billet aluminum wheels (middle) are stronger, but why not be different and use your own CNC billet titanium (left) compressor?

You'll need a turbo big enough for the job, which in this case is a 108mm twinscroll T4 turbo, with custom quad ball bearing CHRA and 100psi capability.

To get enough airflow at 12,000rpm(!) to get the job done, you'll need a skillfully ported head, complete with titanium valves and copper-beryllium valve seats:
Image
Image
Image

And you're going to need a set of camshafts to handle the rpm and withstand tremendous ramp pressures, so why not a set of hollow titanium billets with DLC at only 234 grams each?
Image
Image
Image

And since there is no aftermarket rod up to the task, just ask for a set of billet mmcs-titanium connecting rods at 286g each. Rod/Stroke ratio is 2.07:
Image
Image

For pistons, a set of custom beryllium pistons with DLC fits the bill, and since methanol is the fuel, 13:1 SCR is fine:
Image
Image

A strong piston pin is needed as well:
Image

Toss in a custom titanium billet crank:
Image

A set of 9000cc/min injectors:
Image

And since a factory 4G63 block probably wouldn't hold up, just CNC machine your own from billet aluminum:
Image
Image

No head gasket is used:
Image

And to put all that power to the gearbox, one needs a suitable multiplate clutch:
Image

Yes, it is smaller than a cam gear:
Image

An example of very efficient turbo manifold design from one of their recent projects:
Image
Image

And last but not least, a dynosheet from this car, running 'only' 48psi and hydraulic cams:
Image


Since some of you are wondering what this costs, I know the Ti rods are around $3250 each, and the Ti crank is around $31,000. They are now working on a CNC billet cylinder head and carbon fiber
turbine housings. These guys have good connections with F1 parts fabricators.

Thats all that can be said. Thats truely crazy and awesome. Love all the High end Fabricated parts. :thumb:

Making a whole new block is just awesome. :lol:
