more fuel pressure up top. just a thought.

 

Are you thinking of racing with a highly modified (machined) engine?

 

DistantPulse actually installed this on his car, but without changing to a much larger fuel pump you will not see any benefits...

 

good to know. Can't believe how hard it is these days to just get more fuel on newer cars. What about a boost a pump and a 255? or a 1:1 regulator and a 255 for that matter?

 

???........

 

Stock tunes w/ no bolt ons are pig rich, this is true for the srt4, magnum, old cobras, srt6 etc.

You slap on some bolt ons (pulley, intakes, etc) and it leans everything out and you get some great numbers. (cobras pick up 75 horse with a tune and a pulley)

But as soon as you want to go further, past the stock fuel system, its near impossible to get more fuel then the stock setup wants to give.

Sorry bout the confusion.

 

Any interest in helping out on some shoots? I can teach you the ropes- and will have plenty of work if you decide to become an editor!

 

We tuned one of these cars with this fuel system on it and even maxing out the injectors, couldn't get under 14.8 AFR. When we went to 90% duty cycle, it got down to 14.6, but that's just dangerous so we dialed it back to 80%. We ended up going with larger injectors. Customer should have results this week.

Not sure of his SN, sorry Pete, but he's from CT and worked with my bro at Ultimate Edge.

 

It was probably Bowlman169.

...at what RPM in what gear did you see 14.6 at 80% duty cycle?

 

Between my INMotion tune and the fuel mod that Rob and Woody have come up with I was able to drive the AFR into the 10's with a 181 pulley. The determining factor is boost any time you go above 18.7psi the car starts to lean out. In the end I was able to get a flat AFR of 12.5 in all gears at all rpm's to red line. I know that if I had been able to keep the car till this fall when the air temps dropped I would have hit the 11's In the heat I was running consistant 12.1's and even hit a 12.04. When I started pulling the parts off the motor I found a broken vacumn line so who knows how much that was slowing me down.

 

They did the runs in 4th and 5k and up were lean. Under that it was safe.

This was with stacked pulleys, Needswings intake manis, SL55 intake, custom exhaust, and everything else!

 

This is so very wrong. When i put on the pulley and intake the computer was adjusting the the afr to about 10.8 rising to 11.2 at redline. Way richer than stock.

 

Agreed..

I dyno'ed my mods every inch of the way...

From bone stock - to - bolting on the 185mm / SL55 / Iridium Plugs and keeping the factory tune - I GAINED +52 HP and +74.13 RWTQ and AFR was about the same (10.5 to 10.8) VS Stock @ 5800 RPM and 21 PSI - the bolt-on mods alone did not make my SRT6 run lean...

Tuning gave me an average gain of +25.8 RWHP and +18.1 RWTQ @ 5800RPM (Rock steady 12.5 AFR to 6150 RPM at 21 PSI) with my bolt ons...

The only way I can possibly run lean is in some really dense cold weather (Which I don't see in CA - but I do run a sea level) - or adding crazy mods - - or going back and overleaning the tune...

22 pulls that dyno-tune day and not one IAT overtemp (with the factory HE, IC and pump) not on CEL...

 

good god, 10.8.... really?
thats in the plug fouling range, I wonder how many converter failures there have been due to loading them up with that much unburnt fuel

 

a 5 minute phone call from eric at ultimate edge to us would have done the trick

 

I don't think the system you offer was the problem. I think it was a consensus they all came to after the dyno time. My bro would have more info on it.

 

So what kind of product cost are we looking at to replicate XRay's results without too much chopchop.

 

Glen, I am actually working again! Yay! lol, but I might be interested in this if this doesn't work out. I was a video tech geek in high school and never followed through with it. I have experience with editing and film although everything I used back then is out of date now. lol.

 

Damn buddy, I thought you went the way of the dodo bird. Glad to see you hanging around.

 

HaHa! Yeah, im still lurking from time to time. I have not done a thing to the 6 after my frustration with the fuel issue. Unfortunately, I cannot go Rob's route as I am not going to purchase a zeitronix anytime soon. We still need to hang sometime at track or whatever man!
