Ebay GT45 + 5.9 Magnum + E85 blow thru
Documenting this for my notes. This is my log from my good run last night. I made 4, but this was the only one "worth writing home to mom about". The others were just skating exhibitions coming out of the hole.
So, I can't get this thing to build and hold boost. Must be the cheapo Ebay wastegate and/or controller or the spring. It's supposedly a 10lb spring but it was as lite as the 5lb I had in it before. I'm swapping the spring out next for a stiffer one.
In the log, the lite yellow is the car at the light on the 2-step, building boost and then as it goes down and gets darker green, 1st gear, 2nd gear and finally 3rd is the darkest green. I might be off on some of the shift points though. 9.2psi in 1st coming out of the hole off of the 2-step was the max. After that it just settled to around 6psi. 5626RPM was as high as I twisted. I set my shift light at 5500.
So on the balance, it's making decent times and great trap speed on low boost and low RPM but I'm leaving a lot on the table. This thing has a 6.9x in it easily with better traction and a few more pounds of boost and should still be a decently reliable JY/Ebay turbo build.
Oh and finally, the DA from the track. This was from this morning but when I checked last night it was essentially the same. Kind of funny that the track is literally 3' above sea level but the DA puts it closer to 2400'!
