You did the C32 contingent proud with your 12.6x all motor ET. Well done.

 

Got my tune (TVT) and going to the track tomorrow as part of the West Coast Shootout.
I'm bringing my Code 3 pulley along and plan to do a run or two with it. I'll report back if I get the same results while running a crank, and a crank and SC pulley.

 

Allow me to add a few points. I had a 178 and then got the code three, tried it and got the ok ok ok ok time to shift already. Got a Zetronix at Needswings and bingo the problem became self evident.

My Air / Fuel levels were in the 17 to 1 range. Over 18PSI the fuel map could not keep up and the A/F went to hello its time for a tune. I spoke with James at INMOTION and he will tune the map after I give him the :Air density, temp of air, Boost versis RPM versis A/F data sheet. This I will do after I finish a big crossfire project that Iam trying to get off the ground for the winter.

Simply put with my cooler charge and higher boost, the fuel delivery is taxed beyond its capacity. I even get misfires due to lean misses and the power loss keeps the top end greatly lacking for acceloration. Over 18 PSI is not recommended until you do something to augment the fuel system.

Just talking, Woody chillin on the weekend......

 

I think we're going to need more than just a tune as I had Jerry retune my ECU for high boost when I first installed the combo. I believe the MAP and/or fuel system needs to be upgraded as well. I think the first place to start would be a 3 bar MAP sensor w/ retune. It will still work with the 0-5V signal, but ECU recalibration will be absolutely necessary. The stock MAP just cannot read high enough, and the ECU doesn't know what to do when MAP output voltage approaches 5V anyway. A 3 bar MAP won't reach 5V until about 29 psi which puts 23 or 24lbs well within the ECU's range. (Just my .02)

Please keep us posted on your results! I have gone back to running just the ASP pulley for now with great results on the C32 (a few hundred pounds heavier than the SRT6).

Well, ran with the 181 and the code 3. Unfortunately I was unable to get a good time because all I did in two attempts was spin.
As far as I could tell there were no issues with the way the car ran.

I too am now running just the crank pulley until the great minds around here figure out the correct way to run this combo.

My main reason for going back to the stock SC pulley before leving the track was pulley bearing failure. I figured that I'd be driving 4.5 hours home I didn't want the bearings to be subjected to the extra rpm's for that duration.

That's another problem the great minds have on thier plate.
