I also have some accel runs but nothing official. Please understand, the reason why you can post street racing vids on this site is probably because your in Russia and not in the US (I'm assuming)
but I'm not trying to get banned.
Ok man )) I,ll see you videos ! Thx !

The log makes it even more impressive! 500rpm/s ramp rate, floored at around 2500rpm, full boost 4000rpm.

Hands down for the job done and thanks for sharing bud!

I see videos. You have a realy fast car . I think you have around 650whp by superflow dyno . Your 100-200kmh accel was around 5.2sec by racelogic, becouse gps speed is lower than speedometer . For example, when we check our evoX accel we have 200kmh on a racelogic when we have 215kmh on speedometer )))
P.S. What specs was in that GT-R ? In Moscow, high hp GT-R mk3 stage2 with exhaust, actuators, injectors and intake on 98octane have 870 engNm torque and 660 engHp by superflow dyno. 100-200kmh accel this GT-R's has a 6.0-6.3 sec.

So far this is one of the most impressive turbos I've seen as far as for what I want out of a turbo. The more results I see on it the harder it is to be patient until this summer. The fp red comes up short of what I want to do and seems like with the 8374 I can reach my goals and retain the spool up I want for daily driving which is what I do most. How is the daily driving with where u are at with this turbo? I'm not sure about going as far as u have because I'm trying to avoid messing with the fuel system and screwing up the smoothness I have now.

Honestly the car drives great. The only thing that really gives it up as a "built" car is the clutch, both the noise and the slight howl it makes moving from a stop give it away.
My wife doesn't even know it has the power it has, it drives that normal.

Would love to hear more about the waste gate and actuator setup. I think I remember reading you tried different setups. I am getting ready to purchase this kit. Thanks

I now run a Turbosmart actuator with 3 springs totaling 26psi base pressure. I originally ran it with around 4-5mm preload and got around 26psi with 0% WGDC.
I now run around 8-9mm preload.

Be careful with boostoff preasure... It will make you a surge effect when you'll have a light acceleration on high gear mooving. I think 25psi is an optimal boostoff preasure..

P.S. Tell me plz what ignition advance in the peak of horsepower ? And give us acceleration video
I'd give you my numbers but I can't seem to find a place where the speed limit goes to 200 Klm per hour.
