Standard injector limit

[tk80]

My 33 gtr has very mild mods (exhuast/power fc) and after a tune it made 230awkw. The guys tuning it said the standard injectors were at 90% duty. What's the max power i can get out of the standard injectors and what size should i look at upgrading to?

Will upgrading the injectors allow a more aggressive tune, and if so, how much extra power can i expect?

surely someone out there knows the limit of the injectors............???

But to be serious, the standard injectors run out of go somewhere between 250-300rwkw

yep, at 253 rwkw mine are pretty much maxed. that is with a very rich top end (for track friendliness). possible leaning it off a smidge up top might drop the duty cycle back down a bit and get me to 260 or even 270rwkw. but i would think that would be the max.

Rule of thumb for 85% max injector duty in a cylinder engine, injector cc's = bhp

370cc's = 370bhp

370 bhp = 276 kw

276 kw - losses ~55kw = 221 rwkw

PS; if you had done a search you would have found this calculation ~221 times. The search button is your friend.
