Car Dying on Right Turns

[etxxz]

I've been having this problem for a while and cannot find out what it is...at first i though i was getting oil into my intake manifold (my ae86 had that problem) since there's a tube going to the manifold from the crankcase...then i though fuel pump? idk i changed the filter and there's a whiny noise when i drive the car hard. FPR? My sparks are fine and i'm pumping 89oct. I Need some suggestions we had an event today and there was not 1 run where this ddint' happen to me.

Basically when i go on a hard right turn, the car will bog, loose all power and eventually go again...here's an incar vid of today's event

Nice little drift there at the end. haha

Did you have a full tank?

What happened to ur wiper? I see bad things happening if you accently hit the lever.

Sounds like you are getting fuel starvation. Since the fuel pump is on the passenger side of the tank, you can get starvation on right turns if you are running too little gas. If you haven't already, try adding more fuel next time.

I had major issues below 1/2 a tank so I went to a fuel cell with a surge tank and my problem is solved.

Yea, I thought the EXACT same thing. And, I know it's happened before to me autocrossing. (but I had a wiper on)

[Brew]

I have the same problem when autocrossing with less than half a tank. How much gas did you have?

Simple fix: Always run with a full tank and keep a jug nearby to refuel.

Solo I?

I've had this problem twice. One problem has a logical explanation, the other doesn't.

My coil pack bracket broke, the coil pack fell down and was swinging around, and the wire burned through against the exhaust manifold, and when it touched it (right hand turns) it grounded out and killed the power, felt like fuel starvation though).

The other was my fuel pump relay. Yes, believe it or not, when I made left hand turns, power cut out, and it was caused by the relay. I swapped it back and forth several times to make sure it wasn't a coincidence. I put a new one in, hasn't done it for 3+ years. I have no idea...

I think this is more of a problem on early cars (two pumps) than on later ones.. I've run mine down to the light during an autox and never had that happen.

[etxxz]

I had above 1/2 a tank during the whole event so this is ruled out...infact i filled up on 93 just before we started. I've always had a whiny fuel pump but idk if that's the problem since it survived multiple events and multiple 200mi+ hwy trips between 3500-4500rpm. How can i check. our cars have FPR's right? where is it and how can i check it?

the wiper situation was just becuase it was obstructing the camera's view since i mounted my 5mp digicam in between the headrest and the pass' seat and it help up untill the memory ran out! that last turn was 3rd gear btw *_*

open test and tune day. no class since its the first auto-x event i've been to

My wires are fine but i'll have to see about the relay sounds like wierd problem maybe if something was broken inside the relay

I bet good money that it is the fuel pump. I was starving at over 3/4 of a tank last year before I replaced ALL of the fuel pumps and the fuel filter (87' model). This has been a problem for almost all of the Spec E30 racers. We consider them wear items.

Replace the fuel pump/pumps depending on your year and your problem will be fixed.

I learned that lesson the expensive way . . .

I dare say that there is water in the fuel. This sounds silly and perhaps this is a long shot. The water could be sitting in a little "pocket" at the bottom of the tank and when the car shifts around while turning, it causes the pocket of water to get under the send unit.

[etxxz]

well...its not the relay, there is no water in the tank because then the car would bog from time to time and not just only on right turns. i'm gonna have to get a new fuel pump and i'll report what happens...if you notice during the begining of the video that whiny noise is my fuel pump...that's how loud it is

bad camera position, too low. nice lil drift though.
