    :( Sorry to hear that man. Those keepers are little bitches to get back in! I assume you've poked around with a little extendable magnet to see if you can pick it up?

    Perhaps, but we all know that politicians will say one thing during the election cycle and do something else when elected. I just wish the news would lay off on the nonsense bullshit and actually have real discussions. This interview with Sanders is a perfect example, and I'm glad he called the interviewer out on it: http://www.nytimes.com/2015/08/23/magazine/bernie-sanders-has-heard-about-that-hashtag.html?_r=1

    SW exhaust manifold

    Alternator speed will be reduced to 80% of the original speed. At 8krpm with the new pulley, the alt will be spinning the same speed as it was with the old pulley and the engine running at 6,400rpm. :)

    If the fuel was cut, the engine should stop revving higher. The question then is did the ECU simply not respond to the rising RPMs quickly enough, or did it not cut at all? I would expect a significant change in EGT and AFR if it did actually cut.

    Getting into a bit of an unrelated tangent here, but "Pistons must be manufactured from an aluminium alloy which is either Al-Si ; Al-Cu ; Al-Mg or Al-Zn based." The material itself isn't anything special, it's just the design and tolerances they hold that make it work. There's nothing but engineering cost and reliability stopping us here :lol:
  7. ozzimark
    It certainly can be done, but wear is gonna be an issue. For reference, a piston out of a modern F1 engine, 98mm bore. These guys are putting out north of 300bhp/L with a design life of around 2,000 racing miles between engine changes.
  8. ozzimark
    How do you plan on routing the belt to make the alt spin the opposite direction then? Or am I just missing something obvious? :lol:

    If you've got a higher output alternator, have you considered going to an electric power steering pump? :)

    :tup: Looks like he managed to put all the required vacuum fittings on there too, that makes life easy Can you take a shot inside the runners looking at the transition from the runner to the mounting flange, near the injector bungs? It looks like there are some sharp edges around there that could use some smoothing out.

    Out of curiosity, where do you think I stand on those issues? Ultimately, the way things are going now can't remain. There have been enough societal and technological changes that requires a substantial change to the way the government functions for a proper balance. Right now, I feel like the government is stuck in the past, and is too stubborn to find a way to become more useful to the people it serves. What should be done to fix it? No idea. Maybe put more engineers into offices of political power :rolleyes:

    Going through the questions, some of the "common" poll results are surprising. Many are in favor of mostly legal abortion, while being strongly opposed to the death penalty? :huh:

    Saw a relatively large group of modified Volvos driving around on Goat Island today, mostly with canadian plates. Was an interesting sight to randomly come across while visiting Niagara falls with the gf's family :lol:

    LGspeed, the RSI manifold is topmount, and unpainted stainless steel.

    Ah, I forgot you swapped the compressor wheel. You should update your sig
  16. ozzimark
    Don't worry too much about the size of the compressor itself, compare the compressor maps. 20G, 1 kg/s = 132.3 lb/min, so the peak flow is around 42.5 lb/min The GTX3076 flow map, peak flow of about 65 lb/min The important thing to note here is how the 20G isn't really suited for boost pressure over 2.5:1, or around 20-22psi. If anything, the GTX3076R is too big, the GTX3071R is probably a better match :)
  17. ozzimark
    If you're eying the Garretts, Mark was getting a reasonable amount of boost by 4000rpm with his 0.63A/R GT3582R on an older 2.3L engine, I don't recall the exact number off-hand though. The GTX3076R will flow just as much and should spool 200-400rpm sooner.. at the expense of being a really expensive turbo :rolleyes:

    The manifolds should bring top end VE up quite a bit. Aside from that, I've always felt it is best to go as large as you can get to idle smoothly; the lower the IDC is, the less time the injectors are spraying at the back side of the closed intake valves.
  19. ozzimark
    If airflow and AFR remains constant, IDC will increase to 89-90% at 7500 rpm. If you get more air or run a little richer, it's gonna be even higher IDC. Past 80-85% at those RPMs, the injectors are basically saturated anyhow; there probably isn't enough time for the pintle to close all the way. You'd have to know the actual rise/fall time of the injector to be sure, but I'd say you're running dangerously close to the limit of those injectors. That intake manifold looks pretty good. I gotta get in touch with Nathan soon :D
  20. ozzimark
    I may just get on TB and ask him about it. Did he tell you the runner length, diameter and plenum volume? Or give you an estimate for its target RPM band of highest resonance? :D
  21. ozzimark
    Woah, Nathan is building you an intake mani?! Man, I'm jealous.
  22. ozzimark
    RSI makes manifolds: http://yhst-26451710505916.stores.yahoo.net/850tuhe.html I was gonna make some for myself, H and Ben, but as was said earlier in the thread, just don't have the time to fabricate the design we came up with. <_<
  23. ozzimark
    Damn Greg, that sucks. I hope he makes it, and sees justice served to his attackers.
  24. ozzimark
    This seems to be happening all over the place. Thugs/Gangsters wanting the "respect" for being badass, so they go for the kill anyway, or some shit like that. :rolleyes:
  25. ozzimark
    You know better than this.... power rating for a clutch? How much torque were you putting down, low 400 ft-lbf?
