For my first post of this new blog, i will introduce to you a work of art from some of the most extreme car tuners that appropriately name themselves Extreme Tuners in Athens, Greece, and the name is no joke. Pushing limits requires deep pocket and high knwoledge and skills, and these guys have it all. What they do is producing state of the art engine with massive horsepowers. 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.
The list of cars that they have completed is nothing short of amazing:
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)
Getting 700whp/L from 2.0L @ 8500rpm is one hell of a job, to be getting a mere 10 hp itself is considered to be a great achievement, 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?
A really massive turbo is needed, which in this case is a 108mm twinscroll T4 turbo, with custom quad ball bearing CHRA and 100psi capability.
Custom ported head, complete with titanium valves and copper-beryllium valve seats:
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?
Custom set of billet mmcs-titanium connecting rods at 286g each. Rod/Stroke ratio is 2.07:
For pistons, a set of custom beryllium pistons with DLC fits the bill, and since methanol is the fuel, 13:1 SCR is fine:
A strong piston pin is needed as well:
Look at those sexy looking custom titanium billet crank: Drool
Even the stock fuel injectors for the 4G63 engine is being thrown away for this set of 9000cc/min injectors:
The stock 4G63 block even tho considered to be one of the best if not the best in the industry is being dumped for this custom block made from billet aluminum:
And to put all that power to the gearbox, one needs a suitable multiplate clutch:
Yes, it is smaller than a cam gear:
An example of very efficient turbo manifold design from one of their recent projects:
And last but not least, a dynosheet from this car, running 'only' 48psi and hydraulic cams:
Most definitely one of the great Engineering achievement in the automotive industry.
