Great bit of engineering and engine building!
copied from a local car forum..
Taken from here 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[/URL]), 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? http://img43.imageshack.us/img43/4817/compwheels.jpg 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. http://img97.imageshack.us/img97/5795/gt47killer.jpg http://img541.imageshack.us/img541/2928/turbo3.jpg http://img232.imageshack.us/img232/3429/2000hpturbo.jpg 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: http://img686.imageshack.us/img686/8733/cylinder5.jpg http://img5.imageshack.us/img5/3448/cylinder.jpg http://img94.imageshack.us/img94/4258/cylinder1.jpg 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? http://img820.imageshack.us/img820/1...taniumcams.jpg http://img13.imageshack.us/img13/1205/titaniumcams1.jpg |
Some serious kit there!!!
|
Yeah thats some serious kit with a bet a very serious pricetag.
|
wow that is some serious power from a 4 pot motor ,i bet the titanium bits cost a small fortune .i would love to see the prices .:top:
|
Truly awesome work there!!!
|
I know of one well known Subaru tuner who is building an engine on a par with this for Time Attack next year :king:
Development is king at the moment, why stand still... ;) |
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.
have you seen the rest of the pics? billet block, multiplate clutch smaller than the cam pulleys/iphone 9000cc injectors :cry: |
:woaw: holy fuck!!!! now thats a big turbo. very impressive stuff
|
|
awesome stuff
|
anyone got a link to there other threads pics ,
top link didnt work trist ?? |
Fair play lots of work and money gone into this, but was the graph for this not posted and it made the square root of fuck all in terms of power until like 9-9.5k then it spooled and was all over by 11k. Apologies if I am thinking of wrong one.
Seem to be a suspicious amount of Greek cars making well clear of 1k hp too......:? |

They are drag engines though, don't run normal fuels or anything like that.

I posted up some piccies and graphs of the 400bhp n/a cossie engine a few years back as someone was telling me it was impossible to get over 300bhp lol
Its in a mk1/2 escort if i remember rightly |

That is a interesting thread on the evoforum!
And again the question comes into my head..why do they run such a high comp ratio 9.1 and way above (with good results), where our yb`s running low comp?!? |

That can`t be the only reason, as some of those rev not that much higher?!?

piston speeds (combination of geometry and engine speed) fuel type (102 ron wants higher CR than 95 etc) boost cam profiles But in the case of the YB specifically, its the way that it makes massive midrange torque and lower power output (ie its not a natural revver) than tends to lend itself ok to lower CR |
Stuff of dreams and big money F1 price tags all the way
|
But only at running a good amount of boost, whereas them higher cr. engines need a lot less boost to get the similar figures.

Bugger someone beat me to it
|
:blabla::blabla:
there so good we should view them twice!! |
Last week I dyno another 2ltr engine 16v cosworth with almost same combo, we didn’t use methanol and we had with q16 1035hp crank at peak 29psi. This week we will use methanol to this setup and boost it till finish the turbo. |

there is a lot of threads on different forums over the years from this guy all claiming the same things...highest horse power etc. who pays for all the fancy bits beryillum pistons ...those rods wouldnt fit in an evo engine.....titanium crankshaft is bollocks too....f1 still use a steel crank!!! and time on all these builds...what about blow ups??..you'd be talking over hundred thousand on this evo engine alone.... read through it and he doesnt answer questions asked if the poster seems to know his stuff.....then after a while disappears from thread.and all these engines are in greece....hardly any prices discussed....a lot of bullshit me thinks.i dont doubt they do good power but not what he claims.
1360 bhp cossie engine...really.......why do we have so much trouble getting to 800bhp?? the 412bhp N/A cossie...and only 200 lb torque.....cossie engines do not rev like that claims a 1500 bhp 8 valve volkswagen engine too somewhere. |
Very impressive looking engines and parts, if the claimed figures are true it's simply amazing! :cool:

. As for the rpm.........its modified :cry: |

Whats the problem with the torque? Ever seen an F1 engine?
As for the rpm.........its modified :cry: is it really modified?? and here is me thinking its bog standard!!!!! some of the 90's f1 engines were only doing 12500rpm and this guy has a cossie engine nearly doing it?? |
how else do you think hes gonna get alot of power out of an N/A engine unless he revs it hard.
what were you expecting, it also to push out 350lbs of torque!! f1 engines only produce 250lbs of torque but 750bhp.....god they must be slow! hes not gonna be running the same rod to piston ratio, it even mentions i think the overall cubic capacity is slightly less than a stock one. also hes running 3bar of boost on a GT45, what sort out power did you expect him to come out with, methanol isnt like 109ron fuel we run over here |
I'll sum up and say HOLY SHIT!!!

yes exactly..about 200lb...with all their technology.

Wake up pal, f1 engines will do nearly twice the power and twice the revs ( they are all developed from engines that did ove 20krpm before the tech freeze ) So this guy is nowhere near. As for doing 11k rpm...a stock honda that meets emissions laws in the uk can rev to 9k prm so another 2k rpm with a lot of cash thrown at it isnt exactly mind bendingly impossible now is it? |
You seem to be missing the point that dug is making based on the lower end of 90s F1 engines which is vaguely comparable technology, not on modern ones with have utterly nothing in common with a YB, they dont even run valve springs for example and their tolerances are so close they cant be run without preheating them to the correct temperature.
Anyway, such arguments are pointless, im sure a lot of the parts made for this engine are pointlessly overspecced or possibly even miss specced, but its an interesting build none the less and if I ever win the lottery i'll probably be doing similar with a "everything I can think of" type build as well, such things are no doubt enjoyable if you have the resources even if some aspects of the build arent actually pointfull. |

After all BDA's in race trim often rev above ten grand, and they're prehistoric! I know a litte about f1 engines and their pneumatic 'valves', tolerances and heat cycles, I was merely pointing out power outputs And a 1994 engine is in now way comparable tech to that cossie, also they used much more hi tech exotic materials than they are allowed to now. No berylium alloys these days, just the latest MMC's I had a bike made from MMC in 1994 :cry: Anyway, i'm glad we agree argueing is pointless and that the cossie power output it feasible :clap: |
Love the picture that shows the turbo adjacent the fly wheel, the turbo is the same diameter PMSL!!
