Alright, as a continuation of my Introduction Thread
Only mods between dynos are a LSJION ported head and Option B. I also did some tuning on my own.
*NOTE* When reading the AFR, keep in mind that the WB being used is actually 0.4 AFR lean, so a 12.1 AFR is actually a 11.7 AFR. I just didn't want anybody thinking I was running the car that lean...
Started off by using the *EXACT* same canned ZZP tune that I had on the car last time.
Results were +4whp and +4wtq with gains as high as +6hp/+8tq all along the curve.
Next up is the same ZZP tune with a correct MAF calibration and the stoich adjusted for E5 ( 14.41 )
Results were +6whp and +4wtq with gains as high as +9hp/+7tq along the curve.
After that run, the car started to get heat soaked and I didn't gain anything more peak from my own tuning.
The car drives better than it ever has with the head. All aspects of driving it improved. It definitely feels stronger during WOT acceleration from 4k to 7k, and the dyno backs that up.
However, I believe that having the stock CB on the car has become a major restriction. Every other part of the exhaust flows well. It's a ported head into a BADMAB header, into a ZZP 3" to 2.5" DP, which connects to the stock CB. With the ported head on, the car only dropped 0.5 psi of boost. That tells me that there's a problem with flow.
I believe that the 2 1/16 opening to the resonator and the 2 1/4 bend over the rear suspension are the main culprits.
I plan to install a ZZP 2.5" CB in the near future, then tune for it and see the results on the dyno before I start running E85 and shooting for 300whp.
Here is a composite of best runs for my car.
Low run: 3.0 pulley, DP, ZZP tune
Middle run: 2.8 pulley, header, same exact ZZP tune.
High run: 2.8 pulley, modified ZZP tune, ported head.
Anyway, I hope this info helps someone, and I will post further dyno results in this thread as they come up.
