This will be S mode. S# will be a 92 octane tune via a boost reduction in the map, and a global timing reduction of the Cobb Access Port. I mode will be gas saver/snow mode/waste gate. Here's the dyno graphs - 1st is the last after a long series of pulls. It was heat soaked. 2nd is after a 20 min cool down. I think the later spool and torque on the 2nd graph is due to the SS headers and turbo being cold. It certainly spools faster on the street. 383/390- 385/377 - 25 PSI tapering to 21 at redline Tuned by Jarrad at PDXTUNING in Portland OR.

Wow, I'm confused on why peak torque is so high in rpm range.

My car's dyno sheet showed it spooling about 1000 RPM later than it really does on the street, so in cases like this I just assume it's more about the dyno than about the car.

I just pulled the few VD runs I had, and , spool/PT wasn't that much better. Maybe 250 rpms or so.
I wasn't nearly as knowledgeable about tuning and turbo cars in general back then so, I wasn't out tuning all night seeing what I could get the setup to do. I didn't keep this turbo long before I had Jarrad pop some forged pistons in the motor and at that time I upgraded a bunch of other items too, including and FP Green. Same car, it's just been transformed now a few times. This is the latest version https://forums.nasioc.com/forums/sho....php?t=2890091 Edited to add - that dyno has never loaded my car the same as the street. I always boost more the second I'm off that thing and on the street. I was recently on that dyno and had to turn up the boost from my road tuned settings. It was off (low) by several PSI. In the end it's just a tool. I enjoy doing most of the tuning on the road, and hitting the dyno to fine tune the timing. |

What would you like to know?
I think at this time I was running everything T'd into a single little K/N filter under the car. Big mistake as Ting all those lines into one improperly sized line the exits out of a tiny little filter is a disaster when you take a long sweeping turn at 100+ mph and so much oil comes out the line can't handle it so it blows the lines off your head port. Ask me how I know. If you're going to do a DIY setup - just upsize the dump line accordingly, and don't restrict it with a tiny cotton filter. |
