Re: VORTECH dyno today (corvette184)
Hey,
A thought just came to me..... What size injectors did your kit come with? Perhaps they have something to do with your dip, maybe they are exceeding their duty cycle?
Just another thought.
BTW, please do get some gauges. If you are on the ragged edge with your fuel system, the gauges would be an excellent tool, heck you may find during normal street driving that your fuel delivery is hopping all over the place. Dyno tuning is a terrific tool, but real world dirivng is what you do day in and day out.... Sure would be nice to know how things are going.
Lastly, I did the install about a week ago of some gauges (look for posts elsewhere in this section)..... If you need any tips/advice or additional pictures to reference, please do not hesitate to contact me! :cheers:

You need racetronix fuel set up and some torco from jbsblownc5 here on the forum. That combo will keep your pressure up and the octane for higher rpms as the boost climbs. :thumbs:

Re: VORTECH dyno today (blown in n.c.)
That's what I would recommend too. My fuel pressure was dropping under boost too. I installed a Racetronics pump and now the fuel pressure is stable.

Re: VORTECH dyno today (vetterdstr)
i am running 42lb green injectors......i am only dropping to 53 psi on my fuel pressure.......would that be enough to lose that much power.....and then would the power come right back up if it was low pressure????? :confused:

Re: VORTECH dyno today (corvette184)
Your injectors are probably well suited to your application, but I'll bet anything you're experiencing low voltage to the stock pump when the pressure drops off like that. Looks like a Racetronix should be in your future, though maybe the Kenne Bell Boost-A-Pump would resolve the issue too.
Perhaps others with more knowledge will chime in here. I just know from conversations with Andy, he mentioned it was best to do the fuel pump first and then get the Kenne Bell later as needed.

Re: VORTECH dyno today (JakeL)
Too much timing at those RPM's causing minor KR and timing to be pulled I'd guess. Causing the dip. Could be fuel pressure also. Def need an aux pump, in-tank or boost-a-pump if you care about your engine.
Congrats on the blower!
Watch the tune carefully.

Re: VORTECH dyno today (MelloYellow)
i am going to install a racetronix pump as soon as i can....also put some nice valve springs and retainers in her......i would like a few extra RPMS....and johan already sent me a new tune with more fuel and some more timing....the first tune only had 17 degrees at WOT.....maybe we can get these numbers up around 500 rwhp :crazy: :crazy: :crazy: i will keep you all up to date......

Hi Yano,
Where did you get that hood on the Silver Z06?
Thanks,
Matt

The front is the Tiger shark and the hood is the new Halltech Stinger. The photo is actually a photoshop by Bkuper. But I now have the front end on, and the hood is on its way in about 30 days.

Sounds good, man I will be thoroughly impressed if you can eek out 500 from your combo. So, are you dealing directly with Johan? How long will it take to get another tune?
