(02-06-2018, 05:58 PM)R-3350 i would be interested in the effects with much more fueling. also would be interested in the BSFC with the new chambers.
Adding more fuel is just one way to make more power. The more timing you can run the better, but the stock PCs only fill so fast so they are limited to about 26* of lead time.. Increasing the diameter of the burn holes allows the PC to fill faster, thus reaching ignition temp sooner, allowing injection to happen sooner.
I went a step further and advanced my cam 10* so I am building pressure even sooner. I am currently at 28* and will go to 30* as soon is it gets warm out.. (too cold to work one the car lol). There is a considerable amount of power that can be had by tuning.
Once I find the limit timing wise and settle on a number, I am really tempted to dyno it. I would be really happy if I could see 160 ish at the wheels with stock elements. I have heavily modded the governor (eliminated the high speed governor spring and torque control function) so it does not back off fuel as it revs up.
Larger elements deliver fuel faster, so I will be interested to see what kind of timing I can run when I switch to 10mm elements.
