    looking for a 77 280z , in san diego

    in Cars Wanted

    Posted

    I have a 260Z 2+2 with 240sx 5 speed, that has whole bunch on new parts (read my sig) and I just recently got a TT so kind of being loosing interest in the 260Z. Rebuilt engine, 4 piston calipers in the fronts, sway bars, Eibach springs, Illuminas struts, new interior, etc. email me if you are interested (zolorin@gmail.com)

    Fuel mileage on L6's

    in 6 Cylinder Z Forums

    Posted

    phantom,

    not sounding like a jack ass but you should have tuned your carbs a bit lean -- it does help. I am an aerospace engineer and I had 2 240Zs

     

    first one 73 -- with five speed (early) and 3.9 diffy

    going to florida and back to san diego I would compare mile marker indicators and my gauge (it would be off by maximum 2% i.e. 5-6 miles on 300 mile tank)

    I averaged 24-25 mpg going crazy (average speed of 80-85 mph)

    I got 28 mpg going 65 mph (there were two sections like that)

     

    second one is a 71 with late five speed and 3.36

    I managed to get a 28 mpg going average 85mph from SD to San Francisco

    the odometer with within 1% error of the mile indicated by state (mile markers)

     

    Also I aways fill the gas tank to the same level --- 6 inches from the top of the filler neck -- can't get any more fuel (say within 0.1 gallon error)

     

    also there are 16 gallons in a 72 tank

    1 gallon is unsuable period.

    2nd gallon only if you are flat and level

    other 14 no problem

    and don't ask how I know, let's just say I have had enough expereince on that matter.

     

    My current one 260 2+2 is in high teens (work in progress)

    R200VLSD into R200

    in Drivetrain

    Posted

    Here in san diego there are very few R230 since cars don't die from rust so for the R230s to appear it will take some time. I did came across a R200VLSD (or I think it is) an Infinity with VG30de engine. The test that I did was spin one tire and observe the other and see if it rotates in the opposite direction, and if yes then it is open otherwise ask questions. So this one did not spin backwards which means that it could a VLSD.

    So the first question is, is it an R200VLSD?

     

    Second question is

    I have R200-3.36 (they do exist and 37:11 is a proof enough), I want to make it into the R200-3.36 VLSD. Is it possible to use the guts of the VLSD and stuff it into the desired ring and pinion say from my desired R200?

     

    What else do I need (halfshafts come to mind) etc.

    16 mpg???

    in 6 Cylinder Z Forums

    hm 16 is a bit low

    I have L28 with E88 (domed pistons) with CR of 8.5 and with proper tuning it is possible to get 26 mpg at 80mph on average. in town 19-22mpg so 16 is not the best nor it is the worst.

    the slightly higher CR does not really effect the gas milage that much unless you went from 8.5 to 10.5 (then you are more efficient) and thus saving gas.

    UN Oil for Food

    in Non Tech Board

    Posted

    If Kofi Annan will not resign and they find many leads showing that Oil for Food money were used to fund the insurgenets. US should do the following

     

    1. stop funding UN

    2. evict UN from their office in NYC

    3. veto everything in UN

    4. ask UK to join in stop funding UN

    5. don't provide troop support

    6. and if everything else fails ask the nations that are helping the US to quit UN and start their own organization

    another 4-wheel 5-lug disk conversion =)

    Trust me it will cost you more then 1200 to do that

    240sx calipers (200-250 -- rebuilt)

    rear rotors ($60-70)

    brackets, ss hoses, ebrake, etc ($250-300)

    Front Rotors ($60-80)

    Front Calipers (200-250)

    SS lines front (60)

    So far $830--$1000 unless you use used calipers but then you need a rebuild

    and then you need the convererters or custom hubs to 270 and up up up

    so cheap way yes it will cost you around 1200 - 1300 but that is for the cheapest conversion kit, you might also change the front bearings (and possibly the rears) so it will add another 100-300 on top then a master cylinder for another 120-180 on top

    Understanding Compression Ratio????

    in Miscellaneous Tech

    Posted

    I have not posted on the hybridz forum for the longest time, so lets get back to the question.

     

    Static compression is if you assume that you would fill the cylinder fully with air and then close all of the valves and then bring the piston from BDC to TDC in a very slow manner (adiabatically). Now assuming no heat transfer (and this is what trully adiabatically means) from the compressed air to the outside the pressure will follow ideal gas law such that p1*V1=p2*V2 which means that the pressure will rise proportionally with the volume decrease

    So if volume is reduced 10 times then pressure is up 10 times hence Static CR of 10:1.

     

    This is cute but worthless in the sence that the engine is not compressing in the slow manner but does it very fast some times (7000 rpms is fast) So there is a velocity contribution to the pressure build up, so it can actually increase from being 10:1 to 11:1 or even 12:1 if you compress really fast.

     

    Now to make this more complicated you have cam overlap and timing where the valves open and close which allow extra air to get in some cases or bleed off the dynamic pressure at others, that is why you run a lumpy cam if you have insane amount of CR.
