Can you supply the Engine file please 
If you can tell me where to find it 
C:\Users[YOUR NAME]\Documents\Automation\Engines
don’t forget that most real-life engines make max power before the fuel cut
okay heres a challenge…give me as much power as you can at 12,000rpm push this engine to breaking point!
turbo counts?
non turbo and also stop using 98 leaded I swapped to 100 Octane and I tweaked the engine a bit and I was hitting 255bhp
but sure I dont mind if that monster is turbo charged or not give me a turbo special with well over 400bhp
hit about 277 with a bit og tweaking, max hp for turbo is about 515, can get higher because the intercooler becomes the weak part, 27-28psi is max and it can make much more with a bigger intercooler
impressive to get 515bhp but still its a usable engine not like a 866bhp engine that I have thanks to The Tom who built it which is impractical because of its 8128km range…
Here’s mine, maxed quality control as the engine from the anime was a rally group B motor anyway I don’t feel like it’s cheating too badly.
My 1.6L turbo whit 581 HP and 492 NM. I dont build N/A engines. Only turbo engine.
Hey… ok it’s actually not 4a-ge but it’s still Japanese 
My Honda B16 engine
Honda K20
Honda F20c
And also i made the old Honda S800 high revving engine
(originally this comes from 1966 with 791ccm 10k+rpm and 70hp at 8k rpm)
This thread is getting derailed too much, I believe.
The engine in Initial D was a racing engine “detuned” so that high octane petrol from ordinary station could be used.
The racing class was touring cars, not Formula Atlantic as some seems to think.
Formula Atlantic engines were based on the more common 16 valve 4A-GE, NOT the 20 valve drawn in Initial D.
Just to put the thread back on track. I made an attempt. Using the right tech year and jpn premium fuel. I just got valvefloat at 11k rpm but a lot of power for a 1.6 NA
or if the imagefile won’t load dropbox.com/s/k52092412sqf815/4age.jpg
The engine was a race engine, so the quality/tech sliders can be quite far to the right. Maybe 10-12, or more.
For the head they were at 15
