Jim,Jim Vaccaro said:Mark,, That sounds like awesome setup.
Pete, It will all come down to who uses the bigger shot..
I am changing to 50lb Inj. Keeping boost at 13 but i'll run a bigger shot then you
Pete will help me set it up i am sure...I am a bigger tipper
We really don't care precisely what the air/fuel is, just whether we are on either side of stoichiometric and that is EXACTLY what the OEM narrow-band HEGO sensors are good for. The Zone-5 controller will kill the juice if the HEGOS show that we've crossed over the 450mV stoichiometric point. Once the juice is interrupted, it will not come back on until the system is rearmed.nitrous pete said:The prob with ther sys is the a/f is not accurate, with the zone 5
For a good a/f moneter it cost 1500.00 atlest, that system will
turn off when it shouldent, etc. Just from what I have seen , maby someone figured it out ? or has a better a/f , or they dont use the a/f finction, ? Compucar
Well, we're going to run a 50shot (or maybe even a 35hp) off the line to cool the intake charge and *switch* to a 100shot once I get traction (IOW, the stage1 solenoid will turn off and the stage2 will turn on so the total *on our car* will never exceed 100hp). This is all going to be dry. I was a little unclear in my post about the total that we're going to spray. However, I did say that the '03 Cobra pump was good for 150hp with 50lb/hr injectors assuming one is making 550bhp off the juice. Sorry for that confusion.nitrous pete said:OK I believe you , I just dont uses it , They did not work for me!
I have better luck with Compucar , Nos , and set up all functions through the DFI sys, Or the chip I use , I have used 60-80-100
hp dry No prob. 150 wet, I hink u said. have fun I had many Issues with it. Non Return ! Let me know when U dyno, I know the #s will be hi . I did it 740 TQ , No dought ! But try to go down the track, U should have seen Jim W/the wet sys.
I too agree it works, No the dyno, But not at the track, :shocked
Maby with a return fuel sys.
Thanks Pete. You are totally right. I have a number of hardcore drag racer customers running wet kits on their returnless cars and they are all having fuel pressure issues with 100hp wet shot or higher. As a result, they can't get the air/fuel dialed in with any precision (after all, in order for the PCM to know how much the injectors flow, the fuel pressure has to be known and constant)This is what prompted me to design this system.nitrous pete said:No , its all good, I thought u said it was wet. Sorry
A dry sys . will work fine. I may have read it wrong.
I had No luck with wet systems, they all had good hp at the dyno
but on the track , I went slower. fuel issue .
Good luck,. I know you will run good. have fun shifting with all that power. it feels like a 8 sec. ride. Peace
Hey Pete,nitrous pete said:Cool , I know you will have good luck with it, I love the dry sys,
Sometimes I miss interpret, stuff ? . Let me know how it works
Dyno # track times whatever you do, I'll tell you this my car likes 60hp, Any more and the dyno does wacky, tires spinning, Just because it comes on so hard, So a progressive sys will be great !
60 then 80-100hp whow ,I may try this also.
