    2006 H3 Cold air intake

    never claimed to be all that bright... i just understand how transmissions work in addition to how an engine's powerband affects the way it responds to different loads. for the circumstance at-hand: going uphill increases workload, and if you're at too low of an rpm to make the necessary...

    2006 H3 Cold air intake

    another situation i've found is that even on flat interstate around here, we sometimes get 50-60mph wind. if it's in the face, we find ourselves dropping the H3 to 4th just to hold 65mph (because it's the aerodynamic equivalent of trying to drive 100+).

    2006 H3 Cold air intake

    for reference: the specific example i gave is for a 3mi 6% grade with a 65mph speed limit. my dodge: 20psi of boost at 1700rpm in 6th gear results in EGTs 100° higher than 10psi at just over 2000rpm in 5th. that increases how long i have to sit and idle in the driveway while it cools down so i...

    2006 H3 Cold air intake

    ¿que?! a 3.5 & 3.7 look exactly the same. the only difference is 2.5mm bigger bore, correcting the 3.5's head deficiency, and an extra 22h/17tq. they were both under-powered, but downshifting is all relative. even the alphas downshift on hills... so do i in my 700hp car... and shoot, my...

    Wheel fitment question 20x10

    different vehicle, but a guy i was recently talking with was having a weird vibration at a specific speed (67mph on his car) no matter how many times he balanced his aftermarket wheels/tires. turned out his wheel center bore was ever-so-slightly too big (.5-1mm ish), so he wrapped a thin...

    AC OFF without ENG HOT

    which also involves buying an angle grinder to make a socket i don't foresee another use for. neighbor had a 15mm crowfoot. still took a bit of finagling to get the right angle around the heater hoses & needed a cheater bar on the ratchet... but i got the sensor swapped yesterday. started out...

    AC OFF without ENG HOT

    haha... sounds a lot like the single-purpose item i just said i was trying to avoid & don't have the other tool to make.

    ALPHA conversion!

    2006 was the last year of full-size silverado/sierra with a stick - and the newest they ever had under the hood were Gen3 engines & 0411 PCMs. 09-12 colorado/canyon had the same engines & computers as H3 alphas... but were only automatic (manuals were 2wd 4cylinders). the only vehicles that...

    AC OFF without ENG HOT

    what tool gets this done in 20min? farted around with this for an hour & none of my wrenches are short enough to not hit the firewall, and the wire prevents putting a socket over it. is this one of them "gotta go buy a set of crowfoots" situations? even if i had a grinder, i sure ain't...

    ALPHA conversion!

    keep in mind this is infinitely easier for the automatic trucks than the stick-shift ones... as in i'm only aware of ONE guy who successfully tuned a 5speed v8 swap H3 (H3T, actually).

    BFG,s AT KO3

    70k+ miles on our Cooper AT3-XLTs with ~1/8" still remaining above the wear bars... and they've gotten us down all the trails, snow, & mud we've wanted.

    H3T Stainless Steel Brake Lines For Hummer H3 & H3T

    toss some Russel speed bleeders in the calipers while you're at it. sure makes brake jobs much faster & easier.

    5.3 swap...c125 and c3 connector pinouts needed

    is that a late Gen 3 engine? not used to seeing the blue/green 0411 PCM connectors in an H3.

    what rear shocks are you guys running?

    like i said before - "proper" pressure is determined by your tires' load ratings/indices & how much weight is riding on them. if you run stock-spec tires, use the door sticker data; if you changed tire specs, then you need to do more research. a C-range 35 needs different pressure than a...

    Tranny Recommend?

    the computer needs a similar build's VIN to make the engine programming work - hence the 2010 H3T Alpha to match the 2010 engine swap. having only owned one two-pedal vehicle in high school, i ain't an auto transmission guru... but i'm pretty certain your v8 swap also required a trans swap (or...

    what rear shocks are you guys running?

    i just put Bilstein 4600s all around on my wife's, and they're a little softer than expected. they feel great riding around but still get a little raring back & nose diving when you start/stop moving. i've got them on my dodge 2500 & had them on my previous sierra 1500 (all three with 33-35"...

    Roll Call. What motor is under your hood.

    2009 5spd with the original 3.7 @ 173k ...spent the last 4yrs & 70k debating whether or not to attempt the elusive v8 swap (given i've only seen one guy who got it working right)

    How do I know if I have the plastic shift fork?

    i'm in this camp. that's why forums have search functions.
