Engine stress??? TQ VS RPM????
Re: Engine stress??? TQ VS RPM???? [quote
With less peak horsepower but a flatter torque curve, you can run a milder gear and stay in each gear longer. And the engine with the most transient power (the power to accelerate under load over an rpm range) will be the one that wins the race, not the engine with the most peak hp.

Yes...thats really what Im getting at. I have mentioned peak HP just as a reference...but the goal is basically a flat line of TQ from 3000-6500 of say 600 ft/lbs. Thats a very broad usable range. But if my way of thinking is correct...or at least close...the motor should last a longer time than one that sees 750 ft/lbs at 3000 rpm and tapers down to 475 ft/lbs by 6500 rpm. The peak HP # is just a result which looks impressive
I am not really asking for a blessing...just info and theory on engine stressors and ways to make the most usable power while keeping reliabilty at its highest.

Re: Engine stress??? TQ VS RPM???? Well, the way that I look at it is the control of the nitrous flow is very critical. With a solenoid, you will get an almost instaneous flow of nitrous, and a jump in cylinder pressure that shock loads components. Maybe with a stepper motor, or a servo, you could control the flow of nitrous so that just the right amount is released at any given rpm. Kind of like a water spigot, with a dc electric motor attached. Anyway, my two cents.
Good Luck

Re: Engine stress??? TQ VS RPM???? 2 items for consideration
#1 Nitrous puts a **** load of cylider pressure down low in the rpm range.
#2 it takes 550 foot pounds of tourqe per second to produce 1hp
so if you had no cylider pressure from the nitrous you could dump it anytime you choose,but this is not the town known as perfect and if it was possible then you would not have to turn rpm and if you can get a cam to bleed of like you want then i want that cam!!!!!!
What it all boils down to is V.E.a shitty motor will be able to go lower in the RPM range and gain more than an engine thats built to hanlde the bottle

Re: Engine stress??? TQ VS RPM???? "What kind of simulator was this. This was the kind of concrete engineering type of info I was looking for...thanks...Al "
