Stock crank. No pins. No orings. No fill.
I put in the 160# High Imp injectors today and started tuning them for pump gas. Seems to idle and drive the same once I got them dialed in.

3.5". The plumbing is 3" from the turbo to the IC and steps up the 3.5" with a coupler at the IC. Comes out of the IC 3.5" into 3.5" tubing to the TB where it steps up to 4" with a coupler.
It looks like I need to wrap the exhaust pipe that is near the fuel tank. I drove the car to the track last night (about 25-30 miles) and while I was idling in line, the pump overheated. Basically I am boiling the fuel in the tank which causes it to cavitate the pump and overheat.

I was having some frustration with the 160's acting up suddenly while at a steady RPM/speed. The part throttlevalues in the fuel table were so low that a +/- 1 increment would yield over a 20% change in AFR. I dug into the AEM manual again and found a function that "optimizes" the resolution. It basically doubled the resolution. I then lowered the base fuel pressure from 58psi to 42psi, did some work to the offset table and now they seem to be behaving consistently. Switching to E85 will also effectively increase my resolution.
Finally went back to the track Friday night. First time out on the AEM computer and the 160's. These injectors have me second guessing myself. Not sure if maybe my offset table needs a little more work. Seems like they are perfect everywhere and then everything gets out of wack and leans spot appear that I can feel in the driveability. This is also the first time that I have gone down the track on pump gas and with the exhaust all corked. I made 3 passes. Each gear started off on the lean side (12.5) and ended up on the rich side (11.0) with a perfectly smooth curve.
It was starting off over 13 on the first pass. I guess my adjustments were too soft. Just doesn't look right on the fuel map.
First Pass was a 10.00 @ 136.13 w/ 1.41 60', 9.98 @ 136.84 w/ 1.45, 10.08 @ 137.1 w/ 1.51. Bald Mickeys, 12 psi, 13* timing thru 2 mufflers and a single 3" exhaust.

We are having our East Coast ( West Palm Beach, FL ) private track rental at Palm beach International Raceway on November 7th for our local forum (need2speed.com).
We are really going to bust *** to try to get me ready for the event on E85. LoudmouthLS1 is letting me borrow his injector driver box and BonnarLS1 is going to run up there and grab it tomorrow morning from Devon. LS2Formula and I are going to install it Sunday along with the new 3 bar MAP sensor and the low z 160# injectors. Hope to max out the turbo and maybe see some 8.6's @ 160 ish MPH. Will likely be the death of my little TH350 transmission.
Big thanks to Loudmouth, Bonnar and LS2formula for knocking out a few of my excuses today.Devon supplied the injector driver box. Joe picked it up if BFE North and brought it out to BFE West. He also supplied the 160# injectors. Steve installed the driver box, my fuel gauge, the new pigtail for the new MAP sensor and got my linelock working again. Just gotta switch to e85 and retune. Should be no sweat.
