Ground sensor on housing much better for this info, I can tell how hard I hit my tire within a thou........ just my .01% worth.

I agree with that also! Should we add tire temp too?? Big Grin

Watched Luke's video....

So, let's set the record straight on a few things.... first and foremost, he/Luke has worked hard on his driving and race program to the point he can make a living doing it which means he's a great racer! But this has absolutely nothing to do with what we are talking about here! And this guy would win driving anything! So hanging your hat on this fact is just plain silly with respect to this tread. There are many other folks who can tune a race far better than Luke and other great drivers who just can't drive! The two are not tied together.

Next, Racerdude, you need to retake chassis 101, then go back a watch the video again! The pinion angle he is talking about is totally different than what everyone else is here so it's apples and oranges. He is just referencing the pinion angle vs a horizontal line and or flat ground which he calls ZERO DEGREES. The driveshaft angle has no bearing with his reference to PA! Therefore the numbers he references have no bearing to other combo's with respect to how the rest of the world measures PA! And BTW, come on now, why in the hell would those two builders tell you swat even if you asked, and who says they would even be right! Why don't you call them and let us know how that goes just for kicks.

If your so dead set on following what Luke or anyone else is doing/saying, go try it yourself rather than waste time BS'ing here not to mention stating for others to go try it and report back to you! And a word of advice, just because something works on one combo doesn't mean it would for everyone else's. If you really want to flog this deal, get a data logger with a shock travel sensor and have at it.Then report back to us! Razz



That is why Luke is someone who American trusts to setup and tune their cars at the track. Call American and ask them if they have Luke set up their chassis

Next in the chassis 101, luke is using a different driveshaft so that he can run pinion angles that would put normal driveshafts in a bind to the point of breaking per the article I linked earlier

Next, I have called them. Which is literally why I am telling others to call them who are calling BS on this thread. So please, why don't you do something I already have.

Next, You said I should go do this myself and set up my car this way. I have done that and as stated earlier in this thread I have seen improvement from it. Have you tried it? Have you experimented with it? No? It is easy to say there is no difference on something you have not tried. This is why in this thread I said to go try it and then report back.

yes, you are right that something that works for one combo may not work for others

The thread was originally in regards to what the pinion angle should be on the car. My answer is around -1 degree to start

My further advice is that a pinion angle adjustment can and will make a difference in overall consistency in a car in a game that is often won by thousandths of a second


OK Last time..

American would be crazy not to have Luke's name associated with them even if he had Cole Trickle tuning abilities! In addition he himself states he's no expert. Companies love guys like you who will buy their stuff just because XXX has one.

This tread is about PA in the real chassis world. If you knew what that was, you would have worded your posts to reflect the facts about Luke's video and how his PA is not the same as everyone else's! But you had no idea.

Names seam to do it for you.

You are directing others to do something but held back what you already did and the info you received.

You make statements of your so called testing but provide no real results other than it made a difference.

Your answer to the original tread's question was one degree,, in who's world? You have never demonstrated you even know what it is...

So let me take all your provided info and apply that to my car....

But one quick question, are you using the Metric system or,,, to do all this?? Do I need a tape measure or a micrometer? Do you get all your info from the same guy that sold Jack his bean stock beans.... OK,, sorry, I got carried away for a moment.

It still blows me away that even some knowledgeable racers still are completely lost about what pinion angle actually is. Then we have differences and lousy information floating out there because people are measuring the wrong damn thing.

Driveshaft or driveline angle is quite forgiving, to a point. And 0 is not usually preferred for it.

Why would anyone care what a car's pinion angle is in relation to the earth? By itself, that is worthless data.

If you or I laid it out like Luke, RD (Racerdude) would not have given it a second thought.... but because a famous bracket racer said it,, well then....

Boy I hope Luke don't start posting about how to torque your fuel tank cap!!!!!!!

Sorry, I just couldn't resist,,, again... Big Grin

If he were J.C., I would do whatever he said without question. Anyone short of that.....well ya gotta use your head. I'm not saying that what Luke is DOING is wrong (I can't watch it). But I'm not sure he is explaining what he is really doing clearly enough that average Facebook browsers are going to get it. IMO, when you start getting into pinion angle, the majority of racers start thinking everything but what it is.

That is most efficient. But the needles don't move and thus neither does the lubrication. Agreed that isn't a real big problem quarter mile at a time.

With the bumps on the track, the suspension movement on launch and going down track, would zero really hurt anything compared to .5 degrees?
