Looking for a dyno graph for anyone running the SC1 cam with a Procherger.
My torque seems low with a peak of only 457 and 350 at about 3000rpm Just trying to get a comparison. The low end and mid range feel weak and the car will dead hook 2nd gear with Eagle F1 until about 5000rpm and then will start to break loose. I am thinking some if not all of this is in the tune.
Thanks guys,

Does anyone out there even have anything close to compare to?

here's mine, similar numbers but with a ls6 cam, stock 6.0 heads.
on stock bottom end. i think the torque numbers are low because its
tuned conservitive to keep the motor alive.
talk to who ever tuned the car.
the pic is not that great but you should be able to read it.

Thanks Blown TA,

Do you or anyone else have a pic of the lower end of the graph 1500-4000rpm?
Just feels sluggish down low. Will your car break second with ease on street tires?

na, thats the only one i got. my car is automatic, but i never dead hook
and thats with 295/35/18 bfg drag radials on the steet or track.
who tuned your car?

Mike at Rapid. I did talk to him and he is willing to work with me. My ltft are almost always positive so I am sure that is were some of my problem is.
What does your fuel pressure drop to under WOT? I was down to 44, the next day it was 52 and at idle it is always 58-60. I emailed racetronix last week and they still have not gotten back to me. This is probably contributing to the ltft's being all screwed up. Mike had them spot on when he did the tune. Also were is your AFR under WOT. Mine is 11.2-11.6 and then begins to lift to about 12.0 at 6200.
Is your car really responsive in the low to mid range? Mine just does not feal like its coming out strong.
Sorry for all the questions I am just tryimg to get a gauge, never had a blown car before so this is a totally new experience.

my fuel pressure is 58 idle, about 55 wot, with a BAP and alky.
my airfuel is idle 14-15, wot 10.5-11.1 about.
but its responsive and pulls hard.
if your fuel is down to 40 psi, thats def. a problem, you could be leaning out
at wot.

Did you have a BAP when you did not have the alky inject. Im wondering if I need one now or if I just have a pump problem. What pump are you running? Do you think the ltft in the positive down low would make the car feel sluggish. Oh, what timing are you running down around 1500-3000 and at WOT? Are you using you MAF or are you SD? Is there any chance you could send me a copy of your tune so I can compare where I could be off?
Thanks again you've been a huge help.

the bap is just a temp. fix, until i upgrade the fuel system, i got the alky and bap at the same time. alky will help. i am still running the maf.
i dont know the timing or the ltft, i let my tuner worry about that.
i would just bring it to your tuner, let them check the tune on the dyno and fuel system.

Here is mine with the FM7 cam and 7.5-8psi running 19 degrees of timing on pump gas.

That is around 400rwtq at 3000 RPM and 500rwtq at 4200RPM.

Blown TA,
It just came from the tuner 60 miles ago. Its not easy for me to get there 2+ hours away and a day off work. So I am trying to figure this out my self without getting in to deep. What pump are you running?

Lss1power,
I tried to buy the same cam you have but Futral would not return my calls or email so I settled for the SC1 which has nearly identical specs. 224/232 .581/.595 114 +2. Should this cam with a good tune come pretty close to mirroring your graph.

Does anyone have a tune I can look at?

i am running a welbro 255, which i think is the same one that
comes with the racetronix kit.

I have my LS1 Edit tune you can look at. Numbers and mods in sig.

DarkFormula

iTrader: (80)

Or not, I forgot about the sig limits.

P-1SC @ 12psi
'02 LS6 cam/springs
Regular bolt-ons
Stock bottom end
Stock LS1 intake
Dual 255lph fuel pumps, in-tank and in-line
Delphi (at the time) 50# injectors, 70ish psi fuel pressure at WOT, 60ish at cruising

My current tune that I'd offered above has the new tables for the Mototron 60s I'm running now.

Dark Formula,
Could you email it to dws6@comcast.net
Thanks alot

Anyone have a tune I can look at. I am using EFILive.
