I wouldn't be opposed to meeting one day, my schedule is currently very tight, I have several automotive projects going on, a business startup in the works, and several other endeavors that should not be taken on at the same time.


in car related news, I took the car to the dragstrip last night, and about a week ago. I wasn't going for a amazing time on the first night, but I was pretty stoked when I cut a 12.749 on my first pass, and a 12.789 on the second.



there's a ton left in the short track, and it's been suggested that I shift earlier to get my ET down. peak boost was 8 psi on the first pass, and just over 10 on the second. the engine was leaner than I would like on the first, so I richened it up a bit, on the second I spun pretty bad off the line. unfortunately I was only able to make 2 passes each time out.

Last night was a bit of a disaster, but nothing failed in a catastrophic manner, and I drove home, so I'm OK with that. it all started when I enabled my electronic boost controller and started trying to dial in the bias table. I wasn't going for a record or anything I was just there to tune the car, unfortunately, it was way busier, and it was over two hours between my passes, and I went straight back to the staging lanes after the first pass.

The first pass was absolutely terrible in every way. staged, green light! Bog hard on the line. get less than 1/2 way down and it's going lean, and I missed 4th gear... to say it was frustrating was an understatement... reviewing the datalog back in the staging lanes, the car was going lean up top pretty bad, luckily boost peak was 4 psi, and it didn't hurt anything. on the whole drive to the track, I was also tuning the car and datalogging, and stopping to make corrections wherever I could, I had noticed lean spikes on the top end, and been adding to the VE table where applicable to lower the spikes. my VE table was beginning to look pretty odd compared to the last track day, I should have seen that as a flag and stopped right there.

14.98 ET, I don't care about the rest of it, it was a terrible pass.

pass number two, My VE table is now something like 20% higher in some points than it was the from the morning when I got in the car and drove to work. down low, it's pretty much the same, but above 5000 RPM, it's way different... launch was better than the first pass, but it spun some. and I got out of it about 3/4 of the way down the track when I saw AFR's going lean AGAIN. erg. I got my timeslip, 14.22... pulled up trackside and reviewed the datalog, again, going lean in the same spots...everywhere else is fine. I revised the tune, drove home, and when I got fairly close to home, I goosed it a couple of times, and saw the same lean spikes, they actually got a little worse, coming on lower in the RPM range.

at this point, I'm thinking either the fuel pump, relay, or short in tank hose is failing and leaking fuel internally once the engine starts getting into boost and raising fuel pressure.

I have one of rodney's fuel tanks here, and I think it's time I start putting something a little more robust together.

I'm going to make a sending unit to install one of these into, which will pass WAY more electrical power, in a safer manner than running anything resembling a stock bulkhead passthrough.

I might also try and cram 1/2" supply and return lines to future proof the setup, but I'm not sure that will be required unless I start running E85 (I might).

Thanks, it pulled nicely, but a new fuel system should make a massive improvement.

I'm currently working on this:



the big hole will house a bung for this fitting from ballenger motorsports:

The next biggest hole is for a -8 AN fitting for the fuel feed, and the two smaller holes are -6 for the return line, and the tank vent.

it's designed around using a 4" tube, it will bolt into the tank after cutting the existing lockring assembly out, and installing two semicircle inner bolt rings that will allow the new top sandwich the tank. between the new top, and the bolt rings. 4 of the 20 bolt holes in the top ring will hold the bolt ring halves, the other 16 will all hold the top . the new connector has six 2.8mm positions, and should be more than capable of supporting 2 pumps, and the level sending unit. I haven't yet decided whether I want to run two pumps or not. this time tomorrow, I should have all the hardware to run two pumps, and honestly, I would prefer two smaller pumps instead of one large pump, because I can use a trigger from my MS3 to start the second pump based on boost level or RPM, which should reduce fuel heating.

Up until this past year, I was having to outsource parts like this. I now have a inexpensive CNC Plasma cutter, and handle jobs like this in house as much as possible. I recently produced header flanges for the 3x00 engines, and LZ9 for WOT-Tech, and am about to make a sign for a local (to me) business.


prior to making the sign, I wanted to tune the machine for the material, in this case, 10 GA steel, so I decided to use my tank parts as a trial to make sure I get a nice, clean cut.











I haven't started work on the pump mounts, or the level sender bracket, but I should be able to make that fairly quick. I'm also waiting on a few parts that I don't have yet, and I also need to get another pump if I'm going to install two.
