    Restructuring Forum

    in Announcements

    Posted

    We are in the process of reorganizing forum structure. In effort to ease general forum traffic, most of the stickies/pinned topics are being moved to the FAQ sub-forum.

     

    The FAQ's are now locked from new threads being created, but you may reply to existing threads. Staff will move threads into the FAQ's as needed.

     

    The bulk of the move is complete, but there is still a great deal of housekeeping yet. We ask for your patience and hope that it helps future navigating.

     

    Thanks,

    Staff.

    Seriously scary race car driving....

    1) I have no particular respect for this driver, based on the video alone.

     

    2) I couldn't care less about the danger to himself.

     

    3) He's breaking the rules and that should have consequences.

     

    4) His distraction elevates the potential consequences for his competitors.

     

    5) His competitors know they are putting themselves in a hazardous environment, and that's a choice they make. No one is holding a gun to their head.

     

    6) I see worse on public roads almost daily.

     

    7) His cage is pink.

    Now how come I never hear that in respect to BMW M3's ?

     

    You can consider this your first complaint then :wink: While I'm not on exactly the same page as BLOZ UP, I will tend to agree with him that semi-trailing arm is not on my list of favorite features. I've owned a couple M3's. In stock configuration, the semi-trailing rear is just okay. They can be modified to favor certain characteristics, which is something they did with the DTM cars. For example, stock sweep angle is 15 deg. DTM cars ran around 11 or 12. Production Nissan cars use something closer to 25 deg. The DTM cars were also built for adjustable camber, toe, and roll center. If I ever own another E30 M3, I will seriously consider some of the 'advancements'. My current daily driver is an E36 M3. While not a huge leap in rear suspension design, It does suit my tastes better.

    Fuel tank Question

    The fuel pump i have must be the problem then.

     

    I suppose that depends on how you look at it. I like the stock EFI pump. It's mostly quiet, reliable, and when run at low pressure will provide a LOT of fuel. It would serve you well with the proper regulator. If you'd rather keep your current regulator, then you need a different type of pump. There are plenty of electric pumps available for your application. Try jegs.com and summitracing.com. That'll get you started.

     

     

    Anyone know about the t56 hose i need as well... The one i orderd does hook onto my wilwoods 7/8's master but the connection going to the slave is a quick connect. I hate making new posts just over single questions.

     

    I believe that topic has been discussed a few times here.

    Maybe I'm getting too old for this. I had to read it several times, and I *think* I know what he's saying, but I can't be certain.

     

    Dunlop, could you clarify a few things....

     

    What year of Z?

    What fuel pump and where is it located? (saying "stock" doesn't mean anything)

    Carb'd or injected?

    Too funny, I to sometimes think I want one. Not sure why though. It may be because my uncle bought one brand new and let me drive it... before I had my license :wink: At the time I thought it was a stunning car. And to a young man, use to driving pick-ups on acreage, it was damn fast. I quickly outgrew my desire for one, but the last few years, I've had an itch.

     

    Let us know if you scoop one up.

    Lost fuel pressure. Pump runs but gauge reads 0psi

    The Aeromotive FPRs use a steel ball on an aluminum seat for the valve. It doesn't seal tightly, but it does regulate well. They note the issue in a technical bulletin on their web site also.

     

    I'll fess up to my lack of experience with Aeromotive FPR's. But still... check valves are constructed by that description and they seal 'fine'. Why is this an issue for these regulators?

     

    Also, the OP said "for a SPLIT second the goes straight to 0 very fast". If this is true with a functioning check valve, that seems like a pretty large shunt, doesn't it?

    After doing a little bit of research, it turns out that aeromotive fpr DO NOT hold fuel pressure after the pump is done priming.

     

    Incorrect. A properly functioning FPR will hold pressure just fine after a prime. The loss in pressure after a prime is because there is no check valve stopping the fuel from back flowing through the pump. Or you have a leak.

     

    But, now I'm beginning to understanding what you meant in your first post... the pressure drop to 10-15psi was occurring after the pump stopped running, correct?

     

     

     

    Today, I hard wired the pump is stayed running the entire time, I made adjustments on the FPR and the gauge read accordingly.

     

    So, you're saying the 0 pressure reading you were reporting was with the pump off? But when it's on, you can reach target pressure?

    Is it wiser to just pick up some quick steering arms for the 280Z instead?

     

    The quick knuckles change the geometry of the steering. Installing them is moving away from Ackermann. It's in ongoing argument, but I think you'll find more knowledgeable people pro-Ackermann than anti. Myself, I would prefer to lengthen the arms, if the option were there, simply because I believe the S30 is lacking in this area (close to parallel steering).

    Theres no way its the FPR, I bought it brand new, it has had 5 starts on it and 1/2 mile of driving on it.

     

    Sorry, but that doesn't make it infallible. If you want to test it... pinch off the return line (back to the tank). If the fuel pressure comes up, the regulator is fubar. If the pressure stays down, you have a delivery problem... pump, pump wiring, plugged lines/filter, or a leak. Of course, this assumes the gauge is working correctly. And, Joel is correct, it should never have dropped to 10-15 psi.

     

    And please please please post descriptive subject titles.

    I'll probably add a heat shield below the filter.

     

     

    Interesting concept though, please post some feedback on fuel pump noise once you are done. ;)

     

    It's a lot quieter than my last triple isolated Walbro (rubber+rubber+low durometer plastic). I'd say it's about 25% louder than a stock Datsun EFI pump. At idle, you can't hear it from inside the car. From the outside, you can hear it while standing next to it, but not 8' away. With the engine off, pump on, the tank has a bit of a ring to it. Rubber isolation would probably have taken care of that.

     

     

    It probably would have been easier to just keep the BMW Ron! :D

     

    :mrgreen: I still have my M3 to play with when the Z isn't demanding my attention. It's a fun car. Sometimes I wonder while I'm still playing with these old things.
