Awesome information Alan! In 30+ years of following NHRA I don't think I've heard someone so willing to share information in a Pro class, really interesting info and thanks for coming on Moparts. Keep flying the flag, we'll keep rooting for you!! Also heard your recent interview on WFO radio, good job. (other members, you should check it out if you haven't already)

I know you're an engine guy, I try to pay attention to what's going on behind the flywheel.
I've been told that teams will cut certain proprietary bars out their old cars before selling them to prevent anyone from knowing their particular configuration. Truth or BS? How much are teams involved in the design of the chassis? Do they have they're own requirements/configurations that they like? Or do they rely on the builder to provide what's best? Do you use a certain amount of flex by design in the chassis or do you try to make it stiff and use suspension adjustments and components for desired changes and control? Between testing and racing, I expect these cars get a lot more laps than people may realize? How many runs will you typically get on a car before it's considered used up and sold?
If the results don't match the theory, change the theory.

I'm looking at upgrading my M/S 3" driveshaft. I have heard from some that the C/F driveshafts have helped with et. Have you found the same results? I wasn't sure how much it would help since the rotational mass is on such a small diameter.

I would say maybe years back somebody like WJ or bob Glidden might cut bars out but nobody would these days. I now Jason and Greg's cars probably have thousands of runs on them. Some teams might have their own way of building a car but mostly Jerry Haas does every car basically the same and they work.

I wasn't sure how much it would help since the rotational mass is on such a small diameter. I don't know of anybody in Pro Stock that runs a carbon fiber driveshaft. Pretty much every driveshaft I've ever seen here is a Mark Williams aluminum driveshaft.

Not sure if you want to answer this question....... can I ask how much weight is usually on the back tires, and if the left rear is much more than the right rear?
Thanks, Manny 1100 on the rear wheels. I haven't had it on scales for a while so I don't know how much is on each wheel. As far as a Hans I use a rage 3 I'm not even sure if they make that anymore it's actually molded into my seat so I don't even know its back there which I like.

What's your opinion of 4-wide? the 4wide seems a little confusing to watch but I don't mind it.
