First timer in Street Stock!

If you watch the video of the SP race my car wake up call was behind at the bottom of the hill every race but never lost a race. It looked like I was gaining speed in the flat while others slowed down. Just something to look at and think about.
 
Excellent! I'll take a look. Do you recall the heats they were in by chance?

Heat 3/ white lane, 13/ black, 25/ blue
Finals-- 1/ white, 3/ blue, 7/ black
 
Just watched the heats and yup, in nearly every one of them you hauled in the other cars. heat 25 of the first round was a good example where you made up nearly half a car between drop-in and finish line. It looks like alignment was right at the edge cause the rear would dance around just slightly for several heats, especially coming off the transition.

bracket,
the timer thing you are working on should prove to be use full i'm an old time motor cycle drag racer and the 300 foot timer was what we tuned our set up with. out side the box I think we must be to catch these guys.

I think I just need to find a way to hide a jet pack!

I think your missing my point,you had the faster car in those races,and enough speed to go by them. but if you take two cars that run the same times and one car is faster of the start he will most likely win the race as you would have to break thru the air barrier around him.Drafting only works if you can come up directly behind him and sling shot around him as a nascar driver would do. I'm not saying that the first off the line is always going to win the race but it is a very big advantage if all else is equal.
 
there is so much here that comes into play with having the fastest car and everything has to click. I mean you can have the fastest car and still loose the race all it takes is just a little piece of trash on the track to cause your car to wobble and you lost the race. A goof up in staging could cause you to loose a race cause nobody is perfect and no one will stage a car perfect 100% of the time. Besides, if you do have a car that comes off the line slow compared to other cars but gains speed going through the flat and you win the race. What do you do to the car to make it pick up speed at the start. what If you do something to the car to make it pick up speed at the start and then you loose speed on the flat and then your end result is slower. The only thing that matters to me is the end result. IMO there are too many variables to worry about anything other than the end result. One should concentrate on and perfect the basic fundamentals of building a car And do the very best job you can on wheel and axle prep and then luck on that day will give you the result you get. Don't try to think into it too much or you will drive yourself crazy. The people that are the fastest have perfected the prep process and the basic fundamentals of building a car. I mean ask John, I know of times that he was so busy that he didn't even get a chance to re prep his car from last race put them on the track and still run very fast. I can't do that, so that tells me that have have not yet perfected the prep process. I mean, a racer that used to race here called Donelson Gravity didn't even have a track, used a piece of glass from an entertainment center to tune his cars and kicked some butt on the track. Just my merkin dollars worth.

Agreed! I'm searching for the "perfect storm", I just don't know where to look so I think I need to leave no stone unturned. I think the fast builders have either a good plan or an intrinsic feel for what makes a car fast. I have neither right now, so I gotta figure it out, you know what I mean? I started with the basic setup from the "build a sub3" post and tweaked it a little bit but that only got me to 3.0002 and a sub3 badge after the time adjustment at the Nationals. I think there's more I can gain from optimising my mechanical setup and likely a larger amount I could gain from better wheel/axle prep but I have to start with one or the other and the mechanical setup seems easier to test to me!

Besides, if you do have a car that comes off the line slow compared to other cars but gains speed going through the flat and you win the race. What do you do to the car to make it pick up speed at the start.

One of the posts here about mixing graphite lube on the DFW and oil lube on the rears got me to thinking about a way to see if it would have less breakaway torque at the start. It would be hard to build two identical cars to race head to head so I thought this would be something a timer at one foot would show, among other things.

what If you do something to the car to make it pick up speed at the start and then you loose speed on the flat and then your end result is slower.

But with the incrementals maybe I would know if I hurt myself at the start or in the middle or in the back half of the run so I could try to fix it. If I only go by the finish line timer I would know it was faster or slower but I wouldn't know where I gained or lost.

The only thing that matters to me is the end result. IMO there are too many variables to worry about anything other than the end result.

I might not find anything useful, I might end up confused and lost in the woods, or I might catch up a little bit, either way I learn something and I had fun building the timers!

Agreed! That's why there's about twenty undrilled car bodies on the bench right now.

And do the very best job you can on wheel and axle prep and then luck on that day will give you the result you get.

Wheel prep is still Black Magic to me right now. I'm using the DD4H DVD and products and keeping it as a constant while I test the mechanicals. Once I get a solid mechanical setup I can try messing with wheel/axle prep.

Don't try to think into it too much or you will drive yourself crazy.

Might be too late for that advice..........

How about adding front and rear fenders?

DD4H sells rough cut fenders for a very reasonable price. The price listed on his web site is for a pair of fenders. All you have to do is sand them to your final desired shape and glue them onto the body. I used them on our Street Stock entry from the Nationals. The car's name is Mean Streak if you want to look at the fenders in the video.
 
Tmeyer,

Fenders will cut some time as I'm sure we all know by now. But even without fenders I should be able to get a car to run in the 2.97's. Right now I'm in the 2.98's without them, and I know I can be faster just by working on my wheel and axle prep some more.

Your cars are obviously super fast as you have a sub 2.97 badge and any advice you could give I would be all ears. But I don't think us sub 3 badgers really need to worry about fenders until we can crack 2.98. Its just one more thing that may or may not slow us down.

Having said that, I am going to be building 2 cars for the next event. One will have fenders one will not. I am running both because I want to see what speed I gain with my prep on a standard non fender car. My fender car will be the one that I am obviously trying to get my new badge on.

My overall goal is to get a non fender car to run mid to low 2.97's then I know I can start at least keeping up with some of you top dogs. I know I'm a long long way out from that, but its going to be a fun adventure getting there.

Looking at how many cars in the finals that had fenders I'm sure I'll need to add them eventually!
 
Bracketracer,

I honestly think its more in our wheel/axle prep man. I know I'm going to focus way more on that rather than adding fenders. Derby Dad posted a video I'm sure you have seen, that shows the time that fenders take off. That few thousandths of a second is not going to put us where we need to be, or even remotely close to it. Like I stated before I am going to make one car with and one car without fenders for the next race only because I think I will be close with the axle/wheel prep that I'm doing now to getting my 2.98 badge.

Not sure if you have the DD4H Wheel and axle dvd or not, but I bet just by perfecting that prep your car will do 2.97's with no fenders. Thats what I'm shooting for and then I'll move forward from there.
 
Yep, got the DVD before I switched to oil.

I agree that fenders won't bridge the gap from sub3 to sub2.98 but they do add a measurable benefit so I'll look into them after I get a handle on the alignment, COM, and wheel/axle prep. Which I expect will take quite a while!
 
You can break the 2.98 barrier with a basic no fender car.

In April I ran a car called Plagiarized. It was my first build and was a very basic car that was conservatively built. I think it had more steer than necessary and the weight distribution was not as aggressive as most.

It was purchased as a Dynasty Xtreme Build-A-Kit. extended axle placement with slots, cheetah V2 wheels, and 92x pro axles with groove.

I did not paint it and used Monokote Trim sheets for the finish.

All I did was follow the instructions on the DVD and used a tuning board to set the steer.

The April speeds were
2.9802 Heat 1 Lane 1
2.9794 Heat 23 Lane 2
2.9784 Heat 44 Lane 4
2.9768 Heat 80 Lane 3
2.9787 avg

Bracketracer, what color you gonna make your car next race? I want to know so we don't wear the same dress to prom again! I swear you cant tell our cars apart in the video!

FAIR WARNING VIZ!!!

The little guy wasn't with me, so I got to pick the color this time!
 
Wreckage from testing this month:


I wish I could say I found some speed after all this, but I got nothin'!

On the plus side, I did make a new tool to help polish the outer hub. I stick a dot of 12000 grit paper on it first then a polishing cloth after the Red Rocket. The tip is convex to protect the cone and I scrounged a knurling tool on ebay I wanted to try out. Whaddya think of it?
