Limiting factor for RPMs?

[TC]

Maybe if you actually did some kind of hotrodding YOU could have your own recipes? I think I speak for the majority here when I say "we are tired of TC giving out other recipes with which he has ZERO practical experience"

This is where your wrong and just lying, I have 27 years of experience, remember I've been doing this stuff since I was 16 years old......... What you refuse to acknowledge is I've already been in the scene and I'm on my second time around.......... Sure a lot has changed, but a lot hasn't........ And basically you talk a lot of "Expertise" for a guy that has NEVER built a car.........

Put it this way, why do some of the fastest naturally aspirated cars on the planet(NHRA ProStock) run a 3.6 inch stroke on the crank to achieve 500ci's??.......... Why do they runs such a short stroke??

[TC]

The REAL magic is a Torque Converter. You can take a weenie 300 ft-lbs (not feet per pound, lol) and turn it into 1500 ft-lbs at the wheels, this is why automatic cars are always faster than sticks, right? because 1500 ft-lbs is more than 300 ft-lbs!! y'all just need to get off your asses and start wrenching!

L. M. F. A. O. !

Please read both of these, before making yourself look even more foolish.......

I don't doubt that you've been trying to impress people with knowledge you do not have since you were sixteen. That part I totally believe.

is "been in the scene" secret code for "don't do anything?" 27 years with no accomplishments does not trump 10 years with a ton of bonneville records, drag week wins, etc. And don't even start with the "hasn't built his own car" bullshit unless you're ready to use that same logic on Austin Coil or Steve Petty or anyone else who tunes race cars but does not have one of their own. I.e., shut up already, we've all heard your big boasting claims yet... where are the cars? Every time you share something awesome it's something "a friend of yours" did, then later when we all find out your "facts" were wildly off, you blame that buddy instead of admitting that you are full of crap, all day, every day.

Put it what way? you do realize that I am not even arguing with you? I've tuned a Pro Stock engine and I know more about them than I need to. And a heluva lot more than you, even though that makes you mad.

Don't bother with the lecture on anything car related, I wouldn't take you seriously if you ran the last speed shop on earth.

TC you are just wrong on What made Ricks Car Work, it was not RPM. It was weight per HP made. I followed the car very close and talked to them at several tracks. They took rules that where weighted to try to get Cars like his to be competitive, same with the duel SBC injected cars, then when they where they started taking the weight breaks away to the point the car could not handle the weight and still live.

I know that motor had a funky bore and stroke, just not sure on the actually numbers, I heard it spun over 11,000 rpm, any truth to that??

And you can't say it's not impressive, he had to use a Small block head and you can't get any real port size out of one of those especially back in the 90's, hell the Hemi Ports were probably twice as big........... And like I said the weight was based on Cubic Inches..... Also like you said he made more HP/CI....... that equates to more energy pushing down on the piston which in turns spins the crank faster, now figure that you need X amount of crankshaft revolutions to get you down the quarter mile and the faster you can make those revolutions happen the faster you get down the quarter mile.........

All this coming from a guy that fried 3 MS3 units in one day...........And how many engines have blown up that you worked on??..... I know of at least three that are documented on the net...........Probably more........

Brown Cloud??...........

A great example of why you shouldn't be giving engine advice. This statement is so full of holes it's ridiculous. PLEASE STOP TRYING.

Then explain it, and quit trying to look like the expert that has never built a motor in his life......... Tell me how is HP created and what causes it to increase......,....... What is happening to the crankshaft that is making the dyno read more HP.........

And seriously people allow you to work on their cars??......... You must be one hell of a BS artist.......

Proudly I killed TWO megasquirt 3 CPUs (and probably an Expansion card too). And since I work on racing engines - not the kind YOU claim to have build, but actual running engines that are competitive - they break. A heluva lot more than three have broken... but you don't know about those because you aren't exactly part of my inner circle :-)

Anyways, when did this thread turn from "RPM limiting factors" to "captain Derps-a-lot tells us all about fast RPM-ing"

[dieselgeek]

Let's end this thread with what we all KNOW is a fact:


Alex doesn't know what he's talking about.


The rest we'll just have to leave up to the readers to decide. LOL

...Put it this way, why do some of the fastest naturally aspirated cars on the planet(NHRA ProStock) run a 3.6 inch stroke on the crank to achieve 500ci's??.......... Why do they runs such a short stroke??

Why? Because they're limited to 500ci and they need the bore to optimize unshrouding of the valves. That's why the short stroke... not to "rpm faster."

BTW... what exactly is "rpm faster?" I'm betting your explanation is gonna be worth a couple of snorts. Give it up dude... you always end looking like a jack ass.

[dieselgeek]

I have a weedeater that RPMs faster than my Honda driver. Thus, the weedeater is faster than the honda right? I bet it'll outrun a pro stocker.

by TC's logic, yes, your weedeater is faster than your honda.
And the little .21ci motor in one of my RC cars will outrun anything because it's good for about 25000 RPM. As we all know RPM is what makes cars fast

(torque and horsepower have nothing to do with it, the faster it spins the better! ;)

[JeffMcKC]

[BigBlockMopar]

How about weedeaters made by Honda?
Wouldn't they kick the world's butt like, seriously major?

[TC]

It's amazing that you people can't grasp this concept........ It's about the acceleration at which the crank spins, the more power you apply to it the faster it will spin, a shorter stroke travels less distance to complete one revolution than a longer stroke does, a longer stroke requires more power to complete one revolution in the same "time" that a shorter stroke would take, because it has to cover a longer distance in the same amount of time....... This is simple physics...........

This is all about TIME, because the faster(quicker) everything spins, equates to you getting down the quarter mile faster..........

The Shorter stroke has less distance to travel per revolution which allows the engine to see higher rpm's in a shorter period of time.....
