Stagea Autech

Hey anyone know what size injectors and airflow meters are in the stagea when is standard.

I just got mine tuned with a power fc and its at 95% injector cycle on 14psi making 190kws?

Does that sound right. I would have thought the r33 GTR engine would put out more????

what are the AFR's? sounds pretty low to me.

mine makes 205awkw on 11psi.......and it's an RB25det

oh and in other helpful info, the GT-R injectors are 440cc and should be good for 300kw

How long did the tune take and where are the charts!

[Verms]

I'm picking the car up tonight after work. will hopefully have charts and upload them later on!

Just looks too low to me. Does it feel fast? My RB25DET with an R33 turbo highflowed by GCG was making 245awkw. Unless there is an obvious fault I would suspect poor tune. Do you want to PM me the name of the tuner/workshop? AFRs look conservatively rich but that's not a bad thing. Apart from fuel supply timing would be the obvious thing to look at. The difference between a good tuner and somone who just knows how to operate a PFC can be huge.

It has conservative AFR's (perhaps a bit conservative) so some of the power is to be gained by leaning it back towards 12:1 but I suspect there is more to be gained in ignition timing to wake it up earlier.

RB26's respond well with adjustable cam gears so if you are getting it retuned then investing in some time on the dyno setting them up can reap some good rewards.

Unfortunately sitting here in our loungerooms we don't have all the info so there may be other issues hence the need to take the car to someone with a known history of great results with RB's and PowerFC.

Hei good to hear you got an autech. Did you change your cam gears? My rig runs everything on standard exscept for the power fc, cam gears. everything else is standard. My signature says it all. Where are you located at?

[Verms]

Well i can think that maybe the car had alot more work/bolt ons and i wonder if the importer or the compliancing workshop threw some less than standard parts into it to sell it. I think i might try and get some bigger injecters, fuel pump and fuel pressure reg then maybe look at getting different airflow meters. what are your injectors running on your standard autech?

[stasis]

Shouldnt be. You can take a look at the engine compartment and look at the nuts and bolts wheter they have been opened before. As for the injectors and the fuel system all is standard. If i remembered correctly the injecors are running close to max.

Here is the thing. For my rig parts that i ave changed for increase peformance. Drop in replacement k&n filter, cam gears in/out, 3" exhaust system, power Fc and that was it. I got 236kw @all wheels. I was running mobil fuel when tuned. Everything else is standard, fuel system, engine, boost controller, clutch.
