RedFive Posted March 24, 2007 Share Posted March 24, 2007 So I was on the last leg of my trip back from California and I was trying to avoid filling up a 3rd time. This last bit of my trip is very windy mountain roads for many many miles. I noticed that I was losing power. At first I thought it was just around 4000 RPM, but I'm pretty sure I narrowed it down to the turning. I guess my gasoline was sloshing around to the sides of the tank and not getting to the hose in the center. But my gauge said I had somewhere around 1/8th of a tank. Is that not enough to take serious turns with? Is there some other problem I'm not thinking of? Quote Link to comment Share on other sites More sharing options...
A. G. Olphart Posted March 24, 2007 Share Posted March 24, 2007 Fuel level may have been the problem, but if you were climbing hills in the mountains at the time, it could also be a plugging fuel filter. <> Quote Link to comment Share on other sites More sharing options...
savageskaterkid Posted March 25, 2007 Share Posted March 25, 2007 If I drifted my old truck with less then quarter of a tank, it would slosh to the sides, and lose all power Quote Link to comment Share on other sites More sharing options...
RedFive Posted March 25, 2007 Author Share Posted March 25, 2007 I replaced the filter...hmm...roughly a year ago I think. Quote Link to comment Share on other sites More sharing options...
mom'sZ Posted March 25, 2007 Share Posted March 25, 2007 I don't mean to point out the obvious, but the oxygen contain is less at high altitudes and pressure is less so cylinders don't get packed as full. Generally speaking the higher in the mountains you go the less power the engine makes. Does sound like you just let the tank get a little to empty for spirited cornering though, especialy if your car is fuel injected. Quote Link to comment Share on other sites More sharing options...
RedFive Posted March 26, 2007 Author Share Posted March 26, 2007 I'm aware that horsepower is a function of mass flow rate, but it's unrelated to my problem. I think it may be my fuel pump because it was happening again today for a little while with a full tank. Plus now my pump is making a high pitched whine noise. I have all the parts for my turbo conversion but I just haven't done it yet. Will my turbo fuel pump work with my NA motor if I end up having to get a new pump?

RedFive Posted March 29, 2007 Author Share Posted March 29, 2007 Nobody knows if you can use a turbo pump with a na engine? Quote Link to comment Share on other sites More sharing options...
hughdogz Posted March 29, 2007 Share Posted March 29, 2007 Nobody knows if you can use a turbo pump with a na engine? Hey RedFive, If you simply look it up in a catalog like MSA or Black Dragon, you'll see that they are different parts. MSA catalog says NA is ~$200 and turbo is ~$250. I assume the turbo has a higher flow rate. I'm just guessing that the turbo one will work just fine, it will return the extra fuel to the tank.

Clifton Posted March 30, 2007 Share Posted March 30, 2007 Do you have a 240z fuel tank and are running efi? If so that's your fuel slosh problem. Yes you can use a turbo fuel pump on an n/a motor as long as it is efi. If you are going turbo and need a bigger pump, get an external Walbro. Much cheaper than the mSA pump and will have enough volume for 500+rwhp. Quote Link to comment Share on other sites More sharing options...
