    Fuel pressure

    Is the "NO" in my post easier to read now? :shrug: A/F lbs/hr needed 10.5000 41.19 10.6000 40.802 10.7000 40.421 10.8000 40.046 10.9000 39.679 11.0000 39.318 11.1000 38.964 11.2000 38.616 11.3000 38.274 11.4000...

    Fuel pressure

    NO! If you have a 42 lbs/hr injector that is rated @ 39 psi and at WOT you have 10 psi boost with 39 psi fuel pressure you have a 29 psi pressure differential and your injectors are flowing a max of 36.22 lbs/hr. The question becomes how much fuel does your engine need? I calculate that a 4.6l...

    Fuel pressure

    The presssure increase is correct. OK 42 lbs/hr are only 42 lbs/hr at their pressure rating below that they flow less and above that they flow more. At what pressure either psi or bars is your injector rated 42 lbs/hr. Then we can calculate what they flow at 29 psi (2 bars). Stan Edit...

    Fuel pressure

    As stated fuel flow is based on pressure differential. If you have a 42 lbs/hr injector that is rated @ 39 psi and you have 10 psi boost with 39 psi fuel pressure you have 29 psi pressure differential and your injector now flows 36.22 lbs/hr. On my web site Calculate Change in Fuel...

    RPM's and max HP output

    Same idea different torque curve. I do not have the best of torque curves, not sure where I got it. This is for '00 PI engine and shows shift points at a higher MPH. This should be similar to my '00 GT. Edit: This is the same torque curve wheel torque as in my graph above but I scaled it so the...

    I will give you the price as the web site maybe list price, but for flow numbers that ad does not agree with the web site. The Stage I numbers from the ad are listed as stage II and the flow numbers I posted are listed for the stage III. I did find this. Do not use livernoise cncn 3 vlave...

    Trick Flow 2V N/A 408hp on Horse Power T.V.

    I started out by saying I do not have any numbers for ported Trick Flow 2v heads. So I show both heads as stock. Lets just say if the head porter can not improve the TF heads from 241 cfm to more than 260 cfm there is a problem. I believe someone on here said 291 cfm on the intake for ported...

    throttle body spacer

    The factory system on my '00 GT is a cool air system. Meaning it gets its air from outside of the engine compartment. What system did you install that immediately increased your car 2 to 3 around town and around 4 on the freeway? :shrug:

    just back from the track

    at 6000 RPM with 4.10:1 rear gears with stock size rear tires (245-45-17) 4th gear (1:1) is 111.85 mph also remember that his 112.49 mph is an average and he will be running faster at the strip.

    Went to the track tonight; Got some problems/questions

    It tell me where the car was slower. from 0 to 60' it was .04 slower than your other run but from 60' to 330' it was only .01 slower than your other run but from 330' to 660' it was .09 slower. Which gears were you in and did you change shift RPM? :shrug: 2.16 2.20 60' -.04 6.32...

    Went to the track tonight; Got some problems/questions

    1) why don't you post the 60 foot and 330 foot time for the different runs. 2) what was the weather like today verses the other runs 3) are the 2 tracks at different altitudes just to make sure the cams are timed right what is your cranking compression

    Trick Flow Twisted Wedge Heads Cams and Intake NA Dyno Results

    What i said was With a forged crank available and possibly cheaper than a properly balanced cast crank it might be the way to go. The point being that a cast cranks strength is not determined by RPM but by load it has to handle. A stock engine with a 200 HP shot of nitrous will produce...

    Trick Flow 2V N/A 408hp on Horse Power T.V.

    What amount of boost will you be running? :shrug: Anywhere from 800 - 1200 HP (flywheel) depending on parts and boost level and still be very streetable :D

    Trick Flow Twisted Wedge Heads Cams and Intake NA Dyno Results

    You do have an interesting view on crankshafts. :shrug: There is no reason a cast crankshaft if properly balanced can not be spin to 10,000 RPM safely. The limiting fact is not RPM but how much HP / torque that it can safely handle. :eek:

    Trick Flow Twisted Wedge Heads Cams and Intake NA Dyno Results

    With ported heads you will see peak HP at an even high RPM. Your limiting your RPM also limits the HP you can make.

    NITROUS PERFORMANCE PROBLEM

    The manual says to use those jets with what bottle pressure and what fuel pressure? Since I do not see a location what was the air temperature and do you have a bottle warmer?
