Ballpark 300rwhp. All of the hp figures out there are skewed due to different dyno's reading different things.

how do i kno that it is maxed out
Re: rb20 maxing out MAF? (DawgMode)
do you have an upgraded turbo?
cause you arent going to max out your MAF on a stock one.

you know youve maxed it out when it feels like you hit a brick wall under full boost (car suddenly stops)

That's only true if you have a stock untuned ecu (which you probably would with a stock MAF'd RB20), but there are a couple of things that could cause that. You need a way to read what the ecu is seeing, and stock nissan MAF's top out at 5.15v. Like posted above, you ain't gonna do that with a stock RB20 turbo. And actually my number is a little low. Maybe low 300's rwhp.

LOL, yeah, you're going to need a bigger MAF. Z32 MAF should do the trick nicely. Don't forget you'll need a way to tune for it, along with the bigger injectors. Stock RB20 ECU's are burnable, so if you can find somebody to do it for you, that's a cheap option.

Re: (DawgMode)
Didn't know you had a SAFC. You can change the settings for an AFM with a SAFC, but I'm not sure how well bigger injectors would work with one. Tuning that size turbine with bigger injectors on a SAFC though is a topic for a different thread. You need a real way to tune. SAFC's are for stock turbined "tweaking", not 400rwhp+ serious hp making turbos.
Re: (Cjmartz2k)
yea they are..what are u talkin about..my friend has a 1jz making 560rwhp on just afc and 800cc injectors....

Re: (DawgMode)
when it gets cold around here the 25 would always creep up to 14lbs and start to break up. I always thouht it was running lean....after reading the voltage on my SAFC at WOT I soon realized that the maf was maxing out... Car dynoed 275whp at 12 so that 300 to low 300 is probably right. And yes you can change the setting in the afc with a diffrent maf.
