  1. You know Steve, thats probably the look that defines me...

    Oh for sure - you're a racer at heart and I enjoy seeing that underhood. That's what I meant when I said, your truck has a very genuine sense of integrity, or honesty about itself - there's no complication underhood, it's just straight-up here to kick your ass! LOL. IMO yours is all about execution, not necessarily 'form'. I would continue on that theme, everything done so that servicing components is straightforward and quick, to assure the vehicle can be back into action "before the next round" as it were. I wouldn't change what's in your engine bay, take this as constructive criticism - I would just arrange wires, hoses, components so that everything is uncluttered and easily serviceable; if it needs to be there to make the truck run, make it so that it doesn't slow you down if you have to service something else, just some "uncluttering" to make the truck really look "purposeful" rather than an "unfinished project". I would encourage you to continue that and make it "the Racers' racer". When you are at the track and the old guys look in your engine bay and tell you 'wow, that's simple - I could work on that' I take that as a very high compliment. Everyone there customized their vehicle (you included); but even inside that group, there's a sub-group of folks/trucks that when you lift the hood they just have that barely-legal or outlaw vibe, and your truck is among those - I wouldn't change that, your truck IMO was the most 'unapologetic' one there. Even people that know nothing about cars look at your engine bay and kinda wonder, is that even street legal?! Keep it up. :thumbs:

  2. Your questions - no, transmissions are never slowed down to increase reliability (it's mostly the opposite).

     

    A transmission cooler will not reduce line pressure noticeably.

     

    Yes get the truck tuned - the driveability is more likely torque management or traction control rather than the transmission build.

     

    Your trans guy is misinformed, after installing a shift reprogramming kit in a 4L60 you must get the PCM tuned, specifically you have to set adaptive shift timing to 0.2-secs or 0.0-secs (disable adaptive shift timing).

  3. I'm very sad to hear this, and I agree with you I find there are very few people that want to do what it takes to really keep something nice, and those uncaring people make it very hard for those of us that choose to take good care of what we have. I don't have any life experience to draw from on your situation, but I don't believe there is any time period etc for making a claim, I would not be afraid of your insurance agent (I have found them to usually be really good people) and ask them what they recommend. I am sure that living in Oakland you are already paying a fortune in comp/collision, the underwriter is probably expecting this from the area that you live in. The sucky part is that to repaint a door will probably cost less than your deductible, so you will be paying for the repair (or most of it) anyways. See what your agent says is my advice.

  4. Nice pictures! 2BFAST...breathtaking underhood shots, nice work!

    I have to add - Brian's truck is special. I've seen my share of show rides, and I was completely prepared and ready for lots of bling when he was raising the hood. But still, I gotta say I literally gasped when the hood was raised, pictures do not hit you with the same gutteral impact you get when that hood first comes up. And I've only experienced that with a couple of vehicles I've seen. My favorite part though is the interior. I really think Brian's effort has a real future as a feature vehicle. Brian and Dan's efforts really show.

     

    Mr. P. :)

  5. Nice pics. You didn't get any close-ups of the fastest truck there. Oh well, I will be back next year :)

    :( Sorry - I really didn't take many pictures because of the weather, normally I take tons of snaps. Seriously next time we meet-up, maybe next time I come to KS this summer, we'll definitely do a show-n-shine. :thumbs: IF we had been able to USE the track I would have for sure gotten the fastest SS on video!

     

    Mr. P. :)

  6. Yeah it's a C3/Denali AWD; to bind-up like that suggests either front axle and/or transfer case issues. If you have to have someone rebuild the front axle that's $1400-1600; I have no idea what the refurbish labor/parts are to do the transfer case. You might be able to tell him you'll give $9000-9500 for it, since it needs major repair and have it fixed. But I would not blame you for letting it go either. From what you share, yes I agree with you the drivetrain of the truck as well as bed and cab are most certainly original to the truck.

    Sunday's weather turned-out just beautiful - my fiance and I went to see the National World War I Museum, if you like spending time being a 'tourist' we definitely recommend it -

  8. Sorry to be late in posting these, I finally was able to make time and get them on the server; there are a couple really good photos here especially of Brian's truck (2BFAST), if you want the originals contact me.

  9. Just different opinions. It's all good.

     

    I've considered the small motor with a decent power adder to get the performance yet be easier on the petro.......

     

    Not sure on my direction yet, but that is half the fun (figuring out new combo and then building it and seeing how it runs).....

    What zippy and I expressed is not all that different, the base knowledge that we shared is identical and we repeated each other with one exception - Zippy added his real world advise that in the real world, with crap gasoline, it gets difficult to control mal-combustion once you get into really high cylinder pressures, and that he has found that a much more reliable and workable solution to be using a large displacement engine with moderate boost in street (pump gas) applications.

     

    I am sorry that your thread flared-up with some personal drama, zippy and I will take that off-line. Please do not take my statement as any disparagement about zippy, I have always respected and told everyone that I don't know many other people that have more real-world time working on these projects.

  10. Steve i have to disagree, i think. ...This ... should be a good conversation.

    I am going to have to go into the full discussion over the phone with you, because I only have a moment to reply here. But -

     

    Horsepower comes from torque (delivered over time).

    Motors do not make power, they make torque.

    Torque comes directly from airflow - it is fact that the VE curve of a motor is the exact same shape as its torque curve.

    Hence the more air you can process (i.e. the more VE) then you directly get more torque (assuming perfect AFR & spark timing).

     

    You are correct that the more 'stuff' you cram in the chamber, the higher the cylinder pressure - this is NOT boost, but rather the charge density in the chamber. Higher charge density = faster flamefront speeds = need for reduced timing. Nitrous has the highest cylinder charge density of all power adders, this is why it wants less timing.

     

    Boost is not cylinder pressure, or cylinder density; boost is "resistance to airflow".

     

    I care about the volume of air ingested, not the pressure of that air; now once that air is in the combustion chamber, then the pressure it builds as the piston comes to TDC will matter, because I will require less timing (it's mechanically more efficient). But PSI in the manifold IMO is not as important to me as (1) how much fuel you are using, and (2) is your observed AFR correct. Because to make more torque, you need more HEAT, meaning you need more FUEL, meaning (in-turn) you need more AIR, as in volume (grams) of air.

     

    Displacement does not matter. If you have a short block that is 1.5-litres of displacement and still can somehow 'process' 10-litres of air (along with a matching amoung of fuel) then guess what... you will make 1000+ ft-lbs of torque, just like any other 10-litre naturally aspirated motor will. This is exactly how Formula-1 engines run, btw.

     

    Now your questions about mechanical issues, yes you are correct: valve shrouding is an issue, motors actually do not like big diameter cylinders, but DO like unshrouded valves and to do this you need some minimum bore diameter in the build of the motor. Yes, high cylinder pressures will load more stress into valve seats and ring lands. Yes the crank stroke length will dictate spark timing in the engine (it is the primary variable btw). I agree that adjusting any of these mechanical issues will cause the displacement to change, that is a downstream consequence (the displacement change).

     

    The OEMs know this - look at the new Ford EcoBoost V6, this is the future. The old adage that "Cubic Inches rule!" is only a half-true, it only applies to N/A motors.
