Update to Jim Mulvey's project

I got the impression that the J-bar was already on the car from the previous owner. I can't imagine that they would put it on knowing that they were going to swap to a PHR later down the line.

No it had a TRI-4 bar before....no need for a J-bar. I wouldn't think anyway.......

Uhh.. Hello? Guys, if you have specific questions, just ask me. I'll do my best to find out the answers for you. As for the car, I'll take it for a spin--You know--in the real world. Brake hop is easy to test, right? I'll even ask Jim if he'll join us (or let me borrow the car) for the Pocono Track Day. If the car handles well, I don't care if the design looks good on paper or not.

That J-bar--as installed--only yields 1/16" of lateral deviation (to the left) in 2" of bump.

lol.. sorry for acting like you weren't in the room.. get us the scoop on what's up

I don't drive pieces of paper so I will be more concerned how it actually works in "real life".. Thanks for the info (now about them offsets.. )

[Steve Chryssos]

Well there you go. Jim read the thread, then called and said we can take the car to Pocono in May. It's an open event, so we'll be able to able to compare the lap times against a variety of different cars.

Now if we could only get Dennis to attend charm school.

I thought that was Dennis's version of charming???

Can't wait for the track report.. will the PHR be done by then or will the J-arm still be in place??

[Steve Chryssos]

The J-Bar will still be in place. Of course a full length PHB would exhibit less change. No $#!t. But the J-bar has such great packaging potential, that Todd wants to give it a try. Look at it. It's small, It's light, and it's in front of the axle. It leaves plenty of room for exhaust. So if the minimal deviation is acceptible, it stays.

well im probably at fault for asking

Yes, it is. The "bragging" photos of the suspension were posted here so here is where the critique should take place

.I'll critique that when it happens too. Based on what has been so far they will get that wrong as well.

No, it won't

Ahhh, probably not. Steve1969, that was a funny response, I almost laughed

Look, the bottom line is that the design obviously spent zero time on an actual spread sheet to see how it will respond dynamically (which is never wrong and should always be used as a starting point). It was about how pretty we can make this device that we probably don’t even know the name of. I hope it holds the axle place long enough to get it on and off the trailer. Maybe we’ll put it on a race track someday….of course as long as no other cars are there as one might throw up a rock chip or something.

OK, off soapbox. The design doesn’t work as installed, it doesn’t on paper and won’t on the track…or maybe even the street for that matter. It shour looks good though.

When someone uses the term "bragging" when someone is posting pics of thier car it just makes them sound jealous and bitter. The project update section is for.. well, updating info on projects.. If you think it's just the "bragging" section then why do you read it? I know you are a straightforward talking kind of guy so I am sure you will take this a constructive comment

So, what you are saying is that no matter what they do you will find fault with it since you know best.. gotcha.. way to keep an open mind

No, it won't

Maybe, maybe not.. I guess if they try it on the track and it does work then they can challenge your slide rule to a race.. If it doesn't work I suppose they might rip the parts out and try again. This is like the bench racers that argue theoretical numbers to determin who is faster.. lol..

Like I said, I found the TA to look sorta short, but I'm willing to let someone finish thier project and wait to hear the results. Also, I was able to voice a concern over the set-up without coming off like a "ass".. this is an ability that everyone doesn't have. Then again, with some people that's sorta charming. lol

Ahhh, probably not. Steve1969, that was a funny response, I almost laughed

You laugh?? wow, learn something new everyday.. but seriously, you can't expect to be so blunt and well.. (I can't think of a nice word to put in here).. and not expect people to make note of it. Your known for having a certain lack of social skills but you provide good insight and tech on the board so people have learned that "that's just the way Dennis is". Life would be boring if we were all the same. However, that doesn't make the way you phrase things any less "assholian".. Then again I can be an ass from time to time as well. I suppose it's a matter of degree

I am sure that with your vast array of degrees in mechanical engineering and your boundless experience on the track that you know best. I guess we can add your physic mind reading powers to that list since you seem to know what everyone is thinking.

Again, the trailer and rock chip comments just make you sound bitter against people with money or nice cars, which is a shame since I doubt that is the case.

See, we all need a little time on the soapbox from time to time.. It's funny how many "experts" we have on the internet. You do know you could have accomplished the same "critique" of the system without bashing on the owner or the people that designed it.. right? A few people may think that being blunt like that is "cool" or "being real" but most people just see it as plain old being rude.

So, lighten up and learn that you don't have to hit someone in the side of their head with a baseball bat just to get thier attention.

Based on what I saw looking through the photos of the work done thus far, that would be my guess as to the result of future endeavors

Maybe, maybe not.. I guess if they try it on the track and it does work then they can challenge your slide rule to a race.. If it doesn't work I suppose they might rip the parts out and try again. This is like the bench racers that argue theoretical numbers to determin who is faster.. lol.. I know a few of those "theoretical” guys, my boss is one. He has one of the fastest front engine cars running.

Harsh, maybe. I am tasked with keeping a very large fleet in operation everyday and it takes a few days to come down form ass-holio mode, since I only get 1-2 days a week off there just isn't enough time.

You laugh?? wow, learn something new everyday..sometimes, not often

Again, the trailer and rock chip comments just make you sound bitter against people with money or nice cars, which is a shame since I doubt that is the case.Just my futile attempt at humor

I don't do politics for that exact reason. If you don't want the truth, plug your ears.
So, lighten up and learn that you don't have to hit someone in the side of their head with a baseball bat just to get their attention. You have to admit , it does get attention quick though.

I’ll behave now…unless this gets pulled into suspension.
