Correct, BUT... I'm not 100% that the gauge is correct. It moves too fast for me to see it with absolute certainty, while driving.


I like the idea of checking the sender voltage and checking, I'll also go back and check battery voltage in the log.


I checked the gauges at idle with the vac hose off... so that would be a mechanical gauge at 43psi, power logger at 43psi, and the gauge at 43psi at the same time. I can only assume that isnt chance.


I'll shotgun it with a new fuel filter just out of principal.

like what is the tolerance band on the reported output? I've not seen one.


I've also not seen a better method to log fuel pressure. I am open to suggestions though!  :chin:

Thats sort of what I figured, and I get 43psi at 43psi on the gauge... I'll check for the offset that Mike mentioned, but it would be super weird if those lines crossed right at 43psi. All good tests though.

I drove the car all the way to Warren for the employee car show today. Everything seems to have survived... need A/C in a bad bad way though.

Does anyone have an autometer electric fuel pressure gauge plumbed into your powerlogger? I want to make sure I'm doing this right. Watching the gauge I seem to be keeping up with boost, but in my data log it looks like I'm about 15psi fuel per 20psi boost. I'll change the fuel filter this weekend to play it safe, but I figured I better make sure that the data logger is set up correctly.


I didnt think to have the wife record video of the gauges with her phone, but just from watching I would guess its close.


AFRs in the 10-12 range, bringing the alky on around 5psi, and I have it set to run full pump current at 20psi. No KR, but I've got the timing pulled way back, only 15* at WOT. I'm trying to be conservative.  :icon_redface:


I'm not really stumped or anything, but I'd be happy to take a second opinion on some logs just to make sure I'm not missing anything. Admittedly I've driven the car more in the last week than I had in the previous 7years. Man it feels good to have the car back out on the road!

I really dig that underhood... no clutter!

yup, had to do it when the fabric got replaced.


EDIT: turns out the vanity mirror is shorting, took it apart and couldnt see any obvious arcing or anything. So we'll roll without any lights in that for now.

here's what I found, I've been unplugging things and poking around to look for the issue. So it looks like the headliner needs to come down to find the short. I forget, where is the harness that goes up to the roof with the dome light in it? I might unplug it as a field fix, I'll unplug the cig lighter also to see if that fixes it. I have continuity to ground at the vanity mirror plug also, so I fear the whole wiring up there is shorted to ground.

Nope, Brad, you are right.  The cooler would probably be beneficial in the conditions that Gavin mentioned, or if you were continually hot lapping the car, but about all it does for the average guy is making the coolant run about ten degrees hotter.


Since you probably use your car about the same as I do and in texas, I'll consider the oil cooler not required... and I've already deleted it. Tired of chasing oil puddles around already.


New problem is that I realized why the under hood light wasnt working, same reason the radio and dome lights werent working. Now to track down the short that is causing the blown fuse.

Finally got around to watching the video log. Car sounds and looks good!


Got your grill spring in there too...  :cheers:

One conversation that will never die, oil cooler discussions. :rofl:


man I searched for one to get the scoop and couldnt find much... my bad.

I put 2 bungs in mine, one near the heater box, and one under the floor in front of the test pipe. They say 2 feet from the turbo, but thats not really possible for us. has to be on the top 1/2 of the tube to prevent condensation from killing it.

Whats the logic on deleting it? Just the reduction of leaks/threat of  hose failure? I can only assume that the conditions that warranted the use of an oil cooler were driving patterns that I would not see (i.e. davis dam, extended hard track use, nurinburgring, etc) On the other hand, I already have the stuff and would hate to remove something that was required to protect the engine.
