rollsteer/stagger

This reminds me of the time gray did a video of holding a fence post against the tire while
Someone jumps up and down on the front end as a way of measuring bump steer

20K to win 100 lap race...

2 drivers lead most of the laps and ran next to each other for most of the race, until late when another got both of them and won (passed them about lap 87 or so).

Those 2 cars where the same brand and very close on set up and car A has X stagger while car B has Y stagger. X - Y equaled 2" difference. I don't know what stagger the winning car ran so can't comment.

So how do you make a calculation on which car had the right and which had the wrong stagger out of car A and B?

Hmmm.

Maybe they were both wrong......and that's why Z won!

Here is a puzzle for someone to try:

Say I have 4" stagger measuring off the car and 6PSI on LR tire and 10 in RR:

What is the true stagger the car see's?

How much does the stagger change from the RR and/or LR tires being loaded differently at certain points of the corner?

How much does my LR tire diameter change on the straight (higher wheel RPM), if I was using a "Wide" tire on LR vs a STD LR tire?

My RR tire is 92" in circumference, what is the actual rolling circumference with the static weight on the tire and what is it at max load at some point on the track?

something to think about....

At that point i figured one of 2 things is going on. A lot of delusion, or these guys that are really fast can tell that .010 mills can make a difference in a car, and can feel it.

Have been trying to figure out which one ever since LOL.

If you believe the myth (true or not, I have no idea - IMO it's myth) that been told to me so many times over the years by numerous people:

Bloomer is testing with a shock company, makes some laps comes in and tells the shock guy it needs 1 more click of rebound and tells him to add it on this corner. Well shock guys say even the best of drivers can't feel one click so he does 2 clicks. Scott makes some more laps comes in and rages on shock guy:

"I told you one click not two"


LOL......Shrugs

Note# this was supposedly on the almost full open range on the shock like the LR rebound where 1 click makes very very little change

That was Mr Furneys contention some 10-15 years ago. He always contended that you added an x amount of % to the static stagger based on different track conditions.

Cant use quotes, but Billet i have heard some strange things about Bloomquist. My brother watches him like a Hawk and he says he has brake bias / shut offs on all 4 corners. I dont know thou, obvously he is a special breed so who knows.

Im not much of an arguing type of guy, most of the guys i talk to tell me these type of things and i just nod and agree but in my mind i always wonder where reality fits in.

I've noticed it looks like his RR rarely sparks where his LR is like a flame thrower, wasn't sure if it was different pads on each side or just my eyes playing tricks or??? I think it helps keep heat out of the RR as well. I just didn't think that would be enough brake for most of these cars especially the brake dragging guys

[hucktyson]

That would only matter if his rear end is unlocked which is may be.

Perhaps he has an air locker?

So Mastersbilt Racer gets banned for saying some guy who Krom talked to is full of cr*p? Come on ModJr1... that's pretty lame!

i was curious what got him banned... Surely they deleted what he got banned for if it was that bad

[fastford]

I agree powerslide , swapped a lot of info with masters over the years , i have never saw him out of line , especially compared to some of the other BS that gets a pass on here.....how about an explanation please?

[Kromulous]

Yeah thats really lame 4m.net

MBR is a great contributor in the Tech section.

He knows what post it was, but he's not sure why that drew a ban. Anyways he got 30 days for it. (I think it was about a promoter, not that it was bad just something about one probably like saying something about rocket or another sponsor of the website.)
