Speaking of fuel swirl and distribution....
Over the winter.... last winter that is I made 2 changes to the engine setup. One were the coils. I went with a "different" inductive coil. The second was the injectors. I went from some "Marren American Style" (basically propane injectors) sized 750/1000 to some Paul Yaw ID 725/2000. I intend to throw my old LS1 coils back on as well a a bunch of other's to test the ignition system and various coils. It will also be interesting to compare this years dyno's to last. The distribution will be much more even across the chamber with the new injectors. I'd be curious to see if it leads to more torque and the ability to run slightly leaner as well. Eventually I'll get the thing together and on the dyno for these tests.

Went back to the dyno one more time on pump gas to see what slightly higher boost would effect. Still under 20psi. About 18.8psi peak going to 16 psi redline. Definitely stretching the fuel system to the upper limits. 535rwhp / 406rwtq. The methanol system is almost finished now, so that will be the next very soon!
