Holly crap!!! Wish I had my rex tuned, had a vf39 and it wasn't half as fast...Howmuch PSI u running? Stock trans?

[acnexs]

@Sky9ine im running 20 psi and yeah the trans is stock holding good so far! Tuning makes a big difference!

Sweet man did you keep the stock fuel pump and injectors?

[acnexs]

@KFLY67 yeah man!! ... stock fuel pump and injectors.

Even on an 06+ wrx the 565cc injectors are hardly adiquiet. Injectors duty cycles hit 85%+ with sti/16g turbos on 91-93 octane. It's considered unsafe to hit 75%+ IDC, you hit about 125% IDC With e85 meaning you need 700++ cc injectors to run e85 and a vf22, 30, 34, 39, 43, 48 or other sti/equivalent variants. I've also calculated you need 240lph fuel pump to flow 1000cc per hour. Meaning the stock 140lph fuel pump can only flow 600cc per hour.

@topher5657 2006+ wrx's come with bigger injectors than they did in past years. the injectors are good for all the VF turbos and 16G turbos, anyhting bigger than that, you'll want bigger injectors....getting my vf39 wednesday, going to be using Cobb's vf39 map until i can get it protuned.

@christom yup just the vf39 and bolts on plus the tune.

[AW2005STi]

what year is your WRX dude?

[christom]

what all is done to the car with the vf39?

[topher5657]

I read that you were utilizing the stock injectors and fuel pump with the vf39. Aren't you maxing out the injectors and pump? Or is everything good to go since you got it tuned? Brutally quick car! Nice vid.

[theungrateful34]
