In Topic: Let's Talk About Turbo Sizing, Trim, A/r And Exhaust Back Pressure Ratios

As I alluded to before, I think there is an issue with ignition timing... I also think a standalone would be a good move, better than going bigger on the turbo, at least for right now.

My car is not too crazy, but its powerband is super linear and with stock manifold/heads/cams. The difference between it and every other Motronic setup I have run is that it has consistent adequate timing advance in the high RPM range. This is observed easily in the driving experience ;) Next time anyone is in FL, feel free to stop by and I will show you.

I think this all comes down to compressor-turbine wheel sizing. I would suggest either a mild clipping of your current turbine wheel, or trying out the TD06 wheel. You could always jump ship and get on the Garrett-based families of turbos so you will have more easily comparable data to others on our platform.

Another thing to keep in mind is that the more ignition timing advance you are running, the less combustion energy is going to end up going past the exhaust valves. I have always thought your setup 'seemed' to lack top end timing, but you have been very thorough in your attempts to accurately document your live timing so I cannot really say that as a serious suggestion :P

Another aspect of combustion energy getting past the exhaust valves is your exhaust cam opening angle, and perhaps retarding your exhaust cam timing a little will help keep the combustion event in the cylinder where it belongs. What cam timing are you running currently? I'm guessing the higher duration Enem cams will open sooner than stock, I wonder how much more so?

Just some food for thought and possibly trying to open up the scope of this discussion a little ;)

Yeah, especially after I moved out and my sister was still there, that place was pirate hipster central. My condolences to the neighbors!

At least my shenanigans centered around cars.

Back when I was in Orlando, we ran a different kind of meet, but to me a good venue would be Orlando Speedworld... You couldn't all park in a row and take a picture with your camera resting on the ground (unless you met up before), but you sure could see whose cars are actually quick ;)

Pros - Get to race, lots of beer, get to see cars that are truly fast
Cons - none?

Just trying to heckle a bit... You guys know I love you.

PS-- Moving to the Tampa/St Pete area pretty soon, also might pick up another RWD project. Still have the 850, still not driving it, still just sitting and gets started up periodically to flush some new crappy gas through the lines :lol:

Drop into RWD and say hi to TFT... We gave him a nice new life here and a place to call his own ;)

I am self-banned from tbricks OT so my main use for the site is reading about Kenny's latest transmissions:runs ratio at the track, and looking at all the noobs who weren't around when I was more active there.
