Hard right turns cause fuel shutoff? '95 GSX

Going to work the other day, I was on a tight onramp and pushing my '95 GSX (5-speed) pretty hard through the turn. Almost completely through the turn, the car lurched as if I'd hit the rev limiter, but I was only at around 4k. I figured that, my fuel tank being below quarter and the extended long hard right, I may have moved the gasoline away from the pickup or something. It did the same thing to me this morning with over 3/4 tank on a different, longer but not as tight sweeping right hand turn. It lurched when I rolled into the throttle coming out of the turn this time.

Is this a fuel shutoff, or is there something else that could cause this? Car runs fine on a straight at any throttle position. I haven't found a hard sweeping left that I can experiment on yet.

Thanks for any help in advance...

It's possible the fuel sloshed over, but I believe the pickup has a box around it to prevent that. You may have hit fuel cut. Do you have a boost controller with stock injectors? Where you at full boost?

The car is totally stock save for the air filter and intake kit that the previous owner installed. No aftermarket boost controller.

I was not at full boost either time, and actually only in a slight powering effort, holding the car at around 4.5k the first time in 2nd, 4k in 3rd the second time. The first time, it seemed to cut off before even powering out of the turn. If I have the opportunity, I will check either or both situations again today to try to get more information.

These are both quite long turns (wide 270-degree cloverleaf onramps), if it matters. The first isn't as wide and has a nasty last little right hook, and that's where it cut off.

Getting off the gas and back on seemed to cure everything, but I was almost out of the turn by then as well. I do have an OBD-II scanner here, maybe I'll have to hook it up and see what's really going on.

Thanks,

Jim

Well, a long turn could do it. The pump is on the passenger side and under the rear seat. If you ever take it out, you will see that the tank has a little sheet metal box around the pump that has slots in it. This is supposed to keep the fuel around the pump in tight turns. There should always be fuel in there because it can't escape the box (the slots don't go all the way down). However, a long turn might be long enough for the pump to drain the little be that remains. I don't know, but I've never had that problem, even under 20 PSI of boost and with 720 injectors.

I have experienced this as well in a '95 GS. Long right hand off ramp but only a total of 180 Degrees. I had just installed strut tower bars over a stock suspension and wanted to test the setup. I entered the corner at 65 and exited at 45. About half-way throught it my car started lurching. I saw no warning lights on in the dash. I didn't know what was going on. About a week later on of my bulbs that illuminated my speedo died so I removed the instrument cluster and decided to check the other bulbs. I found the my low oil pressure light was also blown. Replaced it as well. About a month or so later I went around the same corner and low a behold the same thing happened the only thing different was now my oil pressure light came on. I pulled into the convienent store and check. I was about a quart low. Filled it up went down the road came back and the car went iinto the corner at 65mph and exited at 58 with no lurching.

Upon further examination (with a Chiltons manual) I found the my oil pickup is on the right side of the pan. Hence hard right turn oil gets sloshed to left side away from the pickup.

Hope this helps

Thanks for the info! I'll go check and see if my low oil light is toast...

Low oil light functions, but that doesn't mean that's not a problem. Oil level seems to be fine. I'll keep tabs on it.

Just spent all day washing/waxing/cleaning/interior reinstalling/vacuuming the pig. Not the warmest day in SW Pennsylvania, but it needed done. I bought it a few weeks ago and it doesn't look like the previous owner ever washed or waxed the thing. Even after washing and hitting it with a buffer with Meguiar's paint cleaner, then a hand-applied coat of wax, it's still not very smooth. Oh well.
