FROM CHATGTP: "WHY DOES A BLOWER MOTOR LOPE?" : Blower cars, have a distinctive "lope" in their engine idle due to the interaction between the camshaft profile and the forced induction system. Here’s a breakdown of why this happens: Aggressive Camshaft Profiles: Many blower cars use camshafts with aggressive profiles that have a higher lift and longer duration. This means the valves stay open longer and open wider, allowing more air and fuel to enter the engine and exhaust gases to exit. While this is great for high-RPM power, it creates instability at low RPMs, leading to the uneven, loping idle sound. Vacuum Fluctuations: The aggressive cam profile can cause fluctuations in engine vacuum at idle. Normally, a naturally aspirated engine maintains a consistent vacuum at idle, but in a blower car, the vacuum can be inconsistent due to the overlap of the intake and exhaust valves being open simultaneously. This overlap, combined with the supercharger's influence on airflow, causes the engine to "lope" or have an uneven idle. Supercharger Load: The supercharger itself can place a load on the engine, particularly at idle. This load can cause the engine to drop in RPM slightly, creating an uneven rhythm that contributes to the loping sound. Fuel Delivery and Tuning: The tuning of a blower car, especially if it's running a rich fuel mixture at idle, can exacerbate the lope. The richer mixture combined with the supercharged airflow can make the idle more erratic. In summary, the lope in blower cars is primarily due to the aggressive camshaft design, the interaction between the supercharger and engine airflow, and the specific tuning of the engine. The combination of these factors results in the characteristic loping idle that is often heard in high-performance supercharged vehicles.
Sick! Remember when you said in your last video that you would buy a jetski? My preferences have changed. I want a big boy like that, ‘cause, 152??? Insane and cool. The maximum I reached in a regular speedboat was 10 to 40 knots, seriously I almost fell asleep while riding. Great video, keep it up.
That's a kneel down jet-ski. lol. My 50yr old brother with a prosthetic leg tried my Superjet for the first time last week. He fell once. Picked it up quick. You're on a much smaller hull though. Ill give ya that. 550's are awesome little skis! My 6 year old daughter (now 10) started on a 440. I miss that ski.Anyways, keep up the riding! Cheers.
Hey man, we're out here in the desert southwest and ride stand up's all the time. You know why? Because they're addicting, so much fun to shred and a great workout! Keep jamming, it only gets better! 💥
I remember my first time on a jet ski at Lake Powell & if you fell off, they would keep going around in a circle so you could get back on it. My cousin didn't tell me that & I was swimming around trying to ketch it & wore my ass out swimming for it.
