What is the tradeoff between horsepower and torque?
By comparing the results, we can get a good idea of the performance tradeoffs for these two camshafts. The greater horsepower increases the top speed by about 1.5 mph. However, due to the reduced torque, the maximum grade in high gear drops from 6.9% to about 5.4%.
What is the formula for torque on a horse?
The equation for Torque is: Tq=Force X Lever Arm Distance. So it is the amount of force applied over the length of the lever arm measured from the fulcrum to where you applied the force.
How many horsepower does a 5.3L Cam have?
The final mods included a set of 1 7/8-inch, long-tube headers and FAST XFI management. Run with the stock LM7 cam, this 5.3L combination produced 359 hp at 5,300 rpm and 384 lb-ft of torque at 4,200 rpm. After establishing our baseline, we proceeded to perform the cam swap. Off came the coil packs, valve covers and factory rocker arms.
What’s the weight limit for a super stock tractor?
Heavy Super Stock tractors at the Regional level must weigh 8,000 pounds for diesel and 8,300 for alcohol. There are also different vehicle weight rules for modified and stock tractors in the Light SS Class, which weighs 6,000 pounds and Grand National Open SS tractors also have an 8,000 pound weight limit.
How much compression do you need for a low RPM car?
Generally, for a low rpm street engine, you could be safe at 0.040-inch or slightly tighter. High rpm race engines with steel rods will fit into the same clearance but aluminum rod engines must use more clearance (perhaps around 0.050-inch) to accommodate the growth of the aluminum rods.
How to calculate the torque of an engine?
When you choose torque, this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine. For example, if your engine has 350 horsepower then the torque would be 367 foot-pounds, at 5,000 RPM. GO.
How is engine torque related to swept volume?
This is not the whole story, however, because actual engine torque is also directly proportional to swept volume (CID). In formula form: TORQUE = VE x CID. Therefore. even though the maximum torque on a 455 occurs at a lower rpm, the 455’s torque is 13.7% greater (455-400 x 100)/400 than the 400’s torque.
What should the compression ratio be on a 64cc engine?
If your engine has these pistons, expect the compression to be around 8.0:1 which is at least 1.5 ratios away from where it needs to be. The easiest way to improve compression is with a set of 64cc chamber cylinder iron Vortec heads and that 0.015 head gasket, which will push the compression up to 9.0:1
