Don't know you mean by standard as in the ones that come on the car or produced for a rb26? Anyway I have r34 N1's and running 1.1 bar we had well over 530hp but need to dyno again as it has had work since then. Thats on a built 2.7 though.
I mean the same type/size turbos as the car left the Nissan factory.

Your N1's sound cool though! :thumbsup:

i have [email protected] running 1.35bar. could run 1.4 for a bit more power but i went with dano's recomendation and stayed with the safer 1.35.
Not sure what that would be at flywheel though.. maybe 480-490?

I have just over 400 with an Impul ECU and decat. The power and torque curves are very good and it feels that way when driving. Not much below 4000 but climbs smoothly up to 8000 and I leave it there.

I would like more but the car feels bombproof and I don't think I would notice another 50 for fast cruising which is all I do.

Pintio,

So what spec is your engine, (apart from the stock turbos), to see ~480-490?

Manifolds, cames etc etc?

that looks cool, peak power is about 1000rpm before mine, does it drop off quite a bit by 8k? how much boost are you running?

you are running .05 of a bar boost less then me but have much more fueling going on and cams and it seems you are running at a guess in the region of 30-40fwhp more then me..

Sorry that was a type-o :(

520fwhp at 6800rpm, 1.3bar. Limiter isnt a lot higher.

That's really nice Mikster.

Hopefully I hope for something similar in the new year, the only difference is I currently only have 555cc injectors. They may have to go if they are my limiting factor though.

theoretically your injectors should be able to flow upto 550ish flywheel hp. if you are running standard turbo's even if uprated i dont believe they would max your injectors out.

Cheers for that, hopefully I'll find out in the next month or so. :)
