Wow. Incredible!

[QuinnsterKID]

Cleeeeean. Nice build. Have you had a chance to dyno this beast yet?

[getslideways]

any videos?

Awesome build.. Those turbos are crazy I have been in a larger frame GT car and when they're tuned right it's a wonderful feeling under full throttle.

Great build, nice choice on the coilovers I have the same ones. That's also about the only thing my car has in common with yours haha. Is it just me or does the acceleration of these cars get faster and faster in 4th and 5th gear?

[WESLIFE]

Looking good!

[das4]

this is a quality build! monster result

[erykv1]

wow amazing. thanks for sharing!

what kind of exhaust manifolds are those

-edit- totally missed that you mentioned that in your first post! sorry.

680 HP & 720 NM on 95 octane Euro pump fuel and methanol injection at 2.0 bar

any videos?

1.2 bar 500 hp: https://www.youtube.com/watch?v=NR7Q7U7xdR0

Haha thank you, have the exact same feeling, really fast at the 4th gear and even faster at the 5th

wow amazing.

Wagner Exhaust Manifolds


Next step will be 2.5 bar with new upgraded cams and ferrea +1 mm valves.

Wow that car hauls! You need some serious real estate on the highway to stretch it's legs

[Tec_Nine]

Awesome build, looks very strong and well done. Props

[landfill]

Nice!

Just to point out 680 is chp and 559 is whp? It's usually the other way around here when it comes to dyno numbers vs performance :)
Maybe a little skimpy dyno but Acceleration is mental!

What's the turbo specs, turbine side?
What mahle pistons?

Thank you; 19 wheels with slicks will hopefully enough for traction

It is a MAHA MSR500 Dyno which measures correctly imo. Here in Turkey crank hp is more important than whp, in US the opposite :)

Here are the dbn files of 5.5 sec 100 - 200 run

100 - 200 kmh:





When we will finish the setup with the camshafts and valves there will be less lag hopefully . Just with a better shifting and less lag the car can reach 5.0 secs between 100 - 200 kmh.

Specs of the GTX2867:

COMPRESSOR WHEEL INDUCER: 49.70mm
EXHAUST WHEEL EXDUCER :53.90mm

Brake disc size?

My point exactly, you'll find many "600whp" cars here but with much slower times. But even European standards I'd say you have extremely fast car for the power. Unless you have weight reduction.
A/R for turbine housing? Peak tq is quite high rpm.

340 mm

Agree with you, 0.82 A/R , on the last chart that I've posted, between 3.7 and 4.2 sec the car cant accelerate smoothly, after the cams we will rev 8k rpms and solve this problem. The only weight reduction was back seats, but the setup also weights much more than the oem (inkl. me 1700 kg with oem front seats and half tank)

[aysix]

0.82 is really big, considering the GT2871 eliminators for this setup i've seen have an AR of 0.71

[Mikse]

Exactly what turbine housing are those because they look like eliminator housings (machining looks identical with DP flange etc.)? Home-brewed?

Also curious about this.
