Looks like a good hit.

Where are you ET and MPH wise compared to before you pulled compression out of the engine?

.. Both are currently about the same as before and I'm still working on the tune AFR's a bit on the rich side on purpose and I haven't even moved the timing yet I did go from 4.33 gears to 4.10's and the air here is still pretty bad I was hoping for a few more runs that night but someone broke a diff on the starting line so I packed it up ..

….. Raced last night and the performance was off a bit … fast forward to this afternoon … I pulled the car out to wash it and when I went to pull it back in the garage , it would not start … quick check indicated the fuel pump wasn't running … pulled the pump out and hot wired it to a battery and it was singing loud … checked the wiring pass-through and found the fuel pump pin nicely black … so I made a new bulk head pass through out of a nylon toilet seat screw … drilled 2 holes through it just larger than the diameter of the pump wires and ... Voila … it runs … sealed it with some RTV and put the other screw into a small container of E85 to see if I make napalm out of it or not …..

….. Pics of the fuel pump bulkhead connector … note the black pin on the left … also a pic of what became my new bulkhead wiring pass-through … plastic toilet seat screw …..
On the last pass Friday night , the datalogger indicated that the fuel pressure had dropped to 31psi from 45 at 5500 rpm and up … not sure how much this cost me in performance yet
but I'll find out at Wednesday TnT … and here I thought it was the air that was killing ET …..
