    Broken Crankshaft Count?

    In the 13 years of being in the Dmax game I can tell you right now it is a design issue pure and simple. We have tried pretty much every single combo you could. Only the SoCal and Callies Ultra Billet haven't failed us yet in this manner. Both aren't that old so time will tell in the long...

    2016 C@C dual tank system help

    There is also an issue with the float arm catching the filler tube in the front tank iirc and causing a big issue as well with these trucks. Had a dealer send me a picture of this issue after a long battle with this same issue.

    Broken Crankshaft Count?

    Exactly, we have seen a ton of them broken with Fluidampners also. It is a design issue plan and simple. Block really needed to be 2" longer so the crank could have thicker throws. Marketing at it's finest...:rolleyes:

    Which Polymer Pistol?

    I'm a Glock guy through and through! Been carrying a G30sf for almost 20 years now and love the gun(honestly feel naked without it).

    What are you paying for Diesel in your area?

    $2.57 here yesterday in the Danville, IN area.:thumb:

    How much boost before you float the valves?

    60psi at 4500rpms is where my original lbz motor in White Lightning would float. 5200rpms with 40psi never had an issue. It's a combo of the two and the shape that the springs are in also that will determine when they start floating and you will know it quickly as it makes a really distinct sound!

    Twins with Twins, Anyone?

    This would be my guess because that is hell on gears being unloaded and reloaded, like someone who can't/shouldn't be drive a manual trany! Just takes the perfect situation to find the sweet spot and pop goes the weasel so to speak.

    86 Crew cab LB7 build

    This is going to be a sweet truck when you are done! My oldest son has an 85 GMC Sierra c1500 that we are doing a body swap with an 06 GMC Envoy XL with the 5.3L in it. That way he has the square body look with all the 06 features like abs etc. Keep it up boss!

    Low maf reading

    Sounds like the first sensor was junk but the maf calibration needs to be raised to match the intake you have on it since it is reading about half of what it should be at idle. That's where I would start with it.:thumb:

    L5P Banks and Edge dyno comparison

    Larry's is a 17 truck. Next will be the intake from Bank's for it.

    L5P Banks and Edge dyno comparison

    I'm with James, we did the Banks on our truck here and it is 100% stock with just the Derringer on it. Picked up 62hp at the tires and works nice. I think you would still see a nice gain from it James because it does increase the boost level 6psi over the stock setting which would benefit you...

    Updated/Current Oval Piston Roll Call!

    And on this whole subject against popular belief I personal found that not squeezing the quench area seemed to make it more manageable also as my first motor was 15.25:1 comp but I put the pistons are zero deck height with grade C gaskets. This allowed me to run more timing without causing any...

    Updated/Current Oval Piston Roll Call!

    The haze/smoke down low has to do with the difference in swirl created in the cylinder and the fact that the piston has less surface area so there is less heat available in the cylinder. On a 1400hp engine fuel only we didn't see any appreciable difference from the cast ovals to forged round...

    Question: Triple Turbo Reccomendations

    I give that a thumbs up!

    Updated/Current Oval Piston Roll Call!

    Been north of 1700hp with them and deep in the 5's in the 1/8th with them. The only major thing between them and a round bowl is at low engine speeds/low airflow they are smokier, engine dyno testing has shown a too close to call on power differences to decide one way or the other. If you...

    Motec vs Bosch

    I use the both the Bosch 15.1 and the New 25Sport standalone systems and absolutely love them for the full control and endless data that can be collected. I have zero experience with the motec stuff unfortunately. The Bosch stuff isn't cheap but when you are doing epic shit you really do need...
