Can any of you tell me what the factory rev limit is?  And at what rpm and speed?   Had a problem when opening up my 02 Silverado 5.3L got it up to 100 or so mph than the motor seemed to just shut down for a split second, i thought that something blew but it drives fine.  i haven't since brought myself to get it to try to duplicate the problem and thought that i might ask if anyone encountered the same problem

Thanks

Rob :D

What does your speedo go to?? My 2001 Blazer went to 100 mph and the computer would limit the truck to 99 mph. It was a 5-speed and I tried it in 4th and 5th gear, it would do the same thing. GM limits the speed by cutting fuel or spark (not sure which) to limit your speed. I think some were even limited to 95 mph. Reprogramming it with one of the aftermarket programmers will take care of it.

My old 96 s-10 would shut off @ 94. 5 speed 4.3.

 

Seems like I had the 'rado up there before, but can't remember when it cut out, seems like it was below 100 though.

rev limiter determines how many RPM's you can get on a gear.  this is not the same thing as the top speed limit, which can also be changed in the computer.  with the hpp3 you can set your top speed to 128 MPH and your rev limit from 5500-6200 RPM

The trucks are electronically governed to shut fuel off at 98 mph, stock tires aren't rated for higher speeds. Stock rev limiter is 5800 I believe but not sure. I used my HPP to raise my speed limiter to 110 and raised my rev limiter to 6100, shift points are set for 5984 from 1-2 and 5984 from 2-3.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
