Cup cars now race and qualify with the same bullet.

 

Agree 100% the dirt guys don't get the credit they deserve. Been checking out what they run to pick up a few pointers and these guys are no bodies fools. They take a licking and come back ticking under some pretty severe conditions while making some really impressive power. More than you would think or the general perception of the sport dictates.

And hey......I've even got all my teeth, well most of them.

 

They actually have it easy by getting a new engine for every weekend... We use the same engines for months before refreshing, usually racing 2 nights a week.

I'm only missing my wisdom teeth.

I've been wrenching on Late Models for 13 years now and I feel like I just started with all the knowdge the guys around me have. I'm more in tune with chassis setup, but the engines we run are typically 780-800hp torque monsters. We also run some high revving small cube stuff at momentum tracks that have a little less power.

I agree that the conditions they run in are brutal. A pre-cleaner and a K&N filter don't stand a chance at holding back all of the dust these things come in contact with.

 

I think i remeber that issue...but i also remember an issure were big E's car was tested..that car ran low 11's at over 130..this was atleast 10 years ago..Now the motors make more power, the suspension is more advanced, and probly most important, the tires are far far better then 10 years ago..id say that if they set up the car for a 1/4 mile run theyd easily break 9 seconds. A mid 10 is almost garaunteed

yea these engines make 800+ ponies but they also make almost 600 ft pounds, and i really dont care were the power is, youll feel 600 ft pounds lol


Also just an FYI, theres a company located in NC, called musclemotorsports..They buy used Cup parts check thenm out to make sure there useable and sell them..they sell complete motors (slightly detuned to roughly 700) and theyll live all day in stop and go...

 

The oval track gearing in the trans/rearend would kill them in the 1/4

 

think about it..martinsville is a 1/2 mile paperclip...so from center of one corner to the center of the other corner is 1/4 mile..there corner speed is roughly 60 mph in the center of the corner. the speed at the braking point of the strait is roughly 120-125....

ok so now say that the center of the corner is actually strait and there at a standstill...now there isnt a braking point at the end of the strait and the center of the corner is strait..they wont reach 60 by the time they "get out of the corner" and so theyll accelerate though the starit and the corner...

they run like a 5.56 gear at Mville and hit 125 at 9,500

run like a 4.56 gear and itll run 140

 

Has anyone here actually driven a stock car?

 

my wife's car is stock?

 

If you ever saw the heads and intakes it would tell you a lot. I have a set of SB2's at the shop that Foltz did and the matching intake. They can do 400cfm on the intake (which makes more power than the 440cfm versions) and they run .750-.800" lift.

The last time I head that they were making just under 850hp on a 358 cube Chevy. Flat tappet lifters and a 850cfm based carb.

Especially if they have one of Larry Wallaces 440+ cube SB aluminum Mopars. Even then a dumb *** driver can grenade one, and Larry was the head engine builder for Penske a few years ago. I would say it's safe to say these guys can make over 800hp and do it at a lot lower RPM than a Cup motor. They also have more cubes and almost no engine restrictions.

Some are making close to that at the tires...for certain tracks of course.

 

Actually they are in the 700's to the tires.

 

Depending on the track. I remember a couple last year that were low 800's.

 

I know the drivelines are good but not 5-6% loss good.

 

That just means the motors are making more power than you think.

I wouldn't lie to you. This came directly from the dyno operator's mouth from one of the top teams here.
