    Anyone with similar mods? trying to get a HP range where I should be?

    I have a 2009 CTS V SEDAN AUTO. Previous Dyno was with a air raid CAI and conservative tune. I was at 475 RWHP on a mustang dyno. I ran an 11.7 on stock tires at 119.8 MPH with just a tune and air raid, so it's seems to be a strong car. My current set up is the following...

    New era. CAI
    Green long filter
    Brake duct mod-Ram air directly into the air filter
    Brand new stock blower, new everything, snout.
    v hat, blower, etc...courtesy of the dealer to get rid of marbles.
    LPE solid isolater
    Kooks coated headers
    Full kooks mid pipes with high performance cats
    SLP loud mouth mufflers
    2.35 upper pulley-13-14lbs of boost IM GUESSING.
    Weapon X track attack HX
    Dual catch cans
    93 octane fuel

    GOING IN FOR A FULL DYNO TUNE ON A DYNO JET MONDAY. What do you guys think the RWHP will be when my tune is complete? I'm looking for a range so I have something to just give me an idea.. Also, any chance with the new set up I could break into the 10.99 at the track. I was doing 11.77 to 11.91 all day last trip to the track on stock tires.

    do you have injectors? i'm guessing you will run out of fuel way before 566rwhp.

    i guess we'll all know monday.

    and so we are in complete understanding, i didn't mean what the fuel pump can deliver, but rather what the stock injectors
    are capable of. capiche?

    The stock injectors are EXACTLY THE SAME ONES ON THE ZR1 corvette. But I guess they don't make 638hp.... lol

    I was told I do not need injectors unless I'm going to go with e85. Otherwise I'm good will room to spare. As jessie stated we have the same injectors as the ZR 1

    I wonder if it's possible to put smaller injectors on a stock 2013 CTS-V and get the same HP due to leaning it out a little bit and get better gas mileage? Maybe low end throttle response might be a little better too due to it running so pig rich stock?

    Injector size is changed by fuel pressure on our engine setup in THIS car.
    It lowers the Actual injector flow rate at low hp and at idle by modifying the pulse width of the fuel pumps to make it a lower desired fuel pressure, in most cases 30psi, down from the 65-72 it does at full throttle.

    this way the injector always stays in its sweet spot where it has a lot of resolution and control/accuracy.

    Changing to a smaller injector would be a waste of money.

    i think you're blowing smoke. the zr1 is 630 hp and or 530rwhp.(same as my car and i'm at 90%) with added boost, headers, & intake he's gonna be over 95% on those injectors. i dont give a crap, it's not my car but it's silly to play around in the most important aspect of tuning IE: fueling. mike maz, who's doing your tune?

    Instead of saying I'm wrong, call the dealer, ask them the part numbers for both injectors, then come back to this post and apologize...

    If you are at 90% injector, your "tuner" didn't set up to request more fuel.. People have been making 600 rwhp with stock injectors since the cars have come out in 2008. My red one was on the Dyno the second day I had gotten it making 600 rwhp.. On stock injectors. The "fuel injector" issue is just a sales thing for some one to be selling expensive injectors to people that don't know better... 600 hp and higher is when you will run out of injector.. Do some reading...

    I'm confused, are you 530 HP or 634?

    According to his mod list in the header, he has a 2.55 pulley, which would be 530-550hp. NOT 634, he is probably posting his at engine numbers which are still a bit high. Even though recaros probably add at least 50 butt dyno hp...

    I have the charcoal Recaros, they put out 75hp, you must be quoting the saffron ones. Those are 25hp less. Or, he could have installed a Flux Capaciter.

    i dont have headers, just a 2.5 and cai. i listed hp as all manufactures do. do your own math to determine rwhp/tq. i never said the 52lb injectors werent on both cars. all i said was good luck with your tune. and your smart ass know it all replies are why you will never get my business you knuckle dragging hillbilly.
