Put 155 miles on the car yesterday. Still lots to do but I'm increasingly growing happy with the car.

Sounds like she is ready to let loose. I bet youre chomping at the bit to turn the boost up.

Yeah i'm ready to get after it. I still need to find out why its dropping FP at WOT but that will likely be something small.

Why does the rear camber look all fucked up? Looks like that bitch belongs back in chingchong with the tops of the wheels tucked in like that.

I haven't adjusted alignment since i changed the whole rear end setup and it was -1.8 before as it was not a dedicated drag car. It doesn't really look like that in person though, The pictures make it look way worse. ill be going 0 or -.5 this weekend.

Ron what mechanical fuel pump are you using? and what did it cost you? The placement looked nice.

This is actually the oil pump for the dry sump system. It does have a provision for driving a mechanical fuel pump off the rear of it. Be pretty simple to put a Waterman at the back. You'd just have to use a front plate mount instead of the side motor mounts. This one is from A.R.E and is made to bolt to the LS blocks using a bot hole near the top front of the block and the 3 bolts holes one the bottom of the block used for holding the a/c. My dart block doesn't have the bottom holes, so they are drilled and tapped into the pan rails instead.

I was going to put a Waterman in the front cover of my 6.7 Cummins but it stuck out just a little too far and there wasn't room to move the radiator and intercooler any farther forward. Seems like a good idea though if they hold up over time.

Exactly what issues ?

I've had a pair of 044's in mine for about 10 years now, they've been solid the entire time, and that's with a less than ideal supply line from the tank itself

I think you'd rather work on your car than drive it. Not saying that's bad, just an observation. :-)

Nope. Drove mine all year. Only "repair" was an alternator replacement-and that was done in "Mexico." LOL. Someone who lived 5 minutes away had a replacement.


The build is enjoyable, but USING the car is always better!

Is it going lean, or are you just seeing the gauge bounce around a bit?

I just over think everything and constantly think how i can/could do it better. That often puts my car back on the lift. I defiantly DONT like working on it. Im assuming that some extended down time with E85 damaged the pumps a bit. the pressure spikes to about 50 on WOT and then drops to 30ish. I think one pump is going out and its back feeding into the other and no i dont have check valves

What pumps? I haven't looked into the root cause yet but I went really lean on my last pass the other week. Holley hp-1800 pumps. I tested each individually to make sure they both turn on. Going to look into it further tomorrow. Still drove home almost 100mi so I don't think anything was hurt.
