In diesel performance, reaching triple-digit horsepower numbers is usually tied to turbocharging, fueling upgrades, and robust transmission/traction.","simplifiedExplanation":"That’s the power level the guest is known for—about 3,000 horsepower. Making that much power on a diesel usually takes serious modifications, not just a simple tune."}},{"startTime":253.9,"endTime":259.6,"type":"concept","title":"horsepower to the tire","url":"/glossary/horsepower-to-the-tire","quote":"And we had 2500 horse to the tire that we knew it was going to do.","canonicalId":"concept:horsepower-to-the-tire","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Horsepower to the tire” (often abbreviated as WHP) is measured at the wheels, after drivetrain losses from the engine to the tires. It’s commonly used in diesel and drag communities because it reflects what actually propels the vehicle down the track.","simplifiedExplanation":"Horsepower to the tire means the power that actually reaches the wheels. It’s different from engine horsepower because some power is lost through the drivetrain."}},{"startTime":386.1,"endTime":390.5,"type":"term","title":"break the beams","url":"/glossary/break-the-beams","quote":"understands what it's like to break the beams on the very last day.","canonicalId":"term:break-the-beams","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Beams” refers to the timing sensors on a drag strip that detect when a car passes. “Breaking the beams” is how elapsed time and speed are recorded for each run.","simplifiedExplanation":"On a drag strip, there are sensors that time your run.

In high-power diesel builds, the connecting rod must handle extreme cylinder pressures and heat without bending or failing.","simplifiedExplanation":"The connecting rod connects the piston to the crankshaft. When an engine makes a lot of power, the forces inside the cylinders get huge, so the rod has to be very strong."}},{"startTime":850.1,"endTime":870.9,"type":"part","title":"wrist pin bushing","url":"/glossary/wrist-pin-bushing","quote":"...It has a very nice wrist pin bushing in it.

When it “blows,” high cylinder pressure and heat can force combustion gases into the cooling system, often triggered by overboost and aggressive tuning.","simplifiedExplanation":"A head gasket is a seal between the engine parts. If it fails, the engine can start mixing fluids or losing compression, and it can quickly get worse."}},{"startTime":1192.4,"endTime":1192.4,"type":"term","title":"head studs ARP 2000","url":"/glossary/head-studs-arp-2000","quote":"And then we offer head studs ARP 2000, ARP 625 custom-aged.","canonicalId":"term:head-studs-arp-2000","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"ARP 2000 refers to a specific ARP fastener material/grade used for head studs. Upgraded studs help maintain clamping force under high cylinder pressures, which is important when you’re running big boost and aggressive fueling.","simplifiedExplanation":"Head studs are stronger bolts that clamp the engine together. ARP 2000 is a specific strong material/grade meant to handle high power without the head lifting."}},{"startTime":1210.8,"endTime":1217.1,"type":"term","title":"boost test","url":"/glossary/boost-test","quote":"boost test, valves adjusted, like it's all done right to last another 150, 200,000 miles.","canonicalId":"term:boost-test","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"A boost test verifies that the turbo/boost system is producing the expected pressure and that there are no leaks or control issues.

It helps confirm there are no leaks after the repair."}},{"startTime":1263.2,"endTime":1268.8,"type":"term","title":"compound turbos","url":"/glossary/compound-turbos","quote":"with compound turbos and a 14 millimeter stroker pump","canonicalId":"term:compound-turbos","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"Compound turbos use two turbochargers in sequence/combination to improve boost response and efficiency across a wider RPM range. On diesel builds, compound setups can help achieve very high power while managing turbo lag and exhaust energy.","simplifiedExplanation":"Compound turbos use more than one turbo to get better airflow. The goal is quicker boost and more power across the rev range."}},{"startTime":1318.9,"endTime":1322.0,"type":"term","title":"roll cage","url":"/glossary/roll-cage","quote":"Do you want interior?

For racing and sanctioned events, cages are often required and must meet specific rules for materials, design, and mounting.","simplifiedExplanation":"A roll cage is a metal safety frame inside the truck. It helps protect you if the vehicle flips or gets hit hard, and race rules often require one."}},{"startTime":1364.9,"endTime":1371.8,"type":"term","title":"time slips","url":"/glossary/time-slips","quote":"Or it could be a bad boy that you don't care what it looks like at all. You care about time slips, distance pulled, dino graphs, things like that.","canonicalId":"term:time-slips","priority":0.5,"confidence":0.9,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"Time slips are official race results showing elapsed time (ET) for a run, typically used in drag racing. The speaker contrasts show-truck builds with race-truck builds, where time slips and repeatable performance are the real goal.","simplifiedExplanation":"A time slip is the paper (or digital record) that shows how fast you ran in a race. Race trucks are built to produce consistent, measurable results like that."}},{"startTime":1364.9,"endTime":1371.8,"type":"term","title":"dino graphs","url":"/glossary/dino-graphs","quote":"You care about time slips, distance pulled, dino graphs, things like that.","canonicalId":"term:dino-graphs","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Dino graphs” are dynamometer (dyno) plots showing power and torque curves over engine speed.

That matters because driveshaft failures can happen in any direction, and full circumferential containment improves capture.","simplifiedExplanation":"A 360-degree loop wraps all the way around the driveshaft. If the shaft breaks, it gives protection from multiple directions."}},{"startTime":1668.5,"endTime":1675.7,"type":"part","title":"CNC ported","url":"/glossary/cnc-ported","quote":"...a $8,400 cylinder head that was brand new.

The speaker’s key mistake is that their nitrous system didn’t activate, which directly affected their results.","simplifiedExplanation":"Nitrous is a system that adds extra “boost” to make more power.

In diesel/race contexts, dyno rules often specify how RPM is allowed to rise and how much load is applied, which directly affects how safely an engine can be pushed.","simplifiedExplanation":"A dyno is like a treadmill for a car. Instead of driving on the road, the engine runs while a machine measures power, and it can also apply resistance to simulate driving load."}},{"startTime":5012.7,"endTime":5035.6,"type":"term","title":"boost pressure","url":"/glossary/boost-pressure","quote":"...how fast the turbo can spool up at RPM...
