I'd like to get a Robi Spec alignment next time he's in FL.

Not only do I hear they kick uber ***... the sticker shall be mad tyte!

And as we all know, a sticker as cool as Robi Spec's, is a good 15WHP across the whole band!

 

Looks like spelling is your speciality AL lol (cite cheking) . I never said David was crook. I talked to a few alignment shops in the area. they all agreed that there would be better 1/4 mile times with a good alignment. They also said the only way he could see that much gain on a dyno, is if the alignment was so F**ked up to the point where daivd was tearin up tires. they said it seem like he just trying to make a buck. not me you ***. I have buschur parts on my car and I enjoy them a great deal.

(enjoy to poke insults and make smart *** comments) LOL makes alot of sense AL

Whoa dude, real mature.

I don't care if you're poking fun at a friend over the internet, in this sector of the internet it's against the rules, do it somewhere else.

You haven't said anything beneficial to the topic at all in this entire thread, so just don't post in it anymore. I would expect more from a mod, this is just disgusting.

 

electricix,

Here is what you just wrote:

It seems as though whoever you spoke with has a forked tongue. Maybe their ancestry goes back to the same guys that lied to some of mine and stold their land, not sure

They say that a good alignment would better the 1/4 mile times. Well exactly how is that going to happen if it isn't making more power to the ground? I mean an alignment doesn't make the car lighter, right? So it has to make more power or roll easier. The rolling easier would then justify my thought on the dyno. Remember, on the dyno the car is pulled down onto rollers. In the case of an EVO on my Mustang dyno the front and rear wheels are between two rollers, meaning it has basically 2 rollers per wheel it has to run against. That is a lot of drag if you have each wheel pointing in a different direction. For an example of this put your car on pavement and push it in a straight line, then just turn the front wheels and try to push it, huge difference.

Also, I am tearing up tires. That's why I re-aligned it. I have a set of basically brand new Neovas on the car that are junk on the insides from the toe being so far off.

Thanks,

 

I cant wait to get my alignment.

Dave, you speak the truth and everyone cant grasp it!

 

Ok I have a legitimate question. This is not trying to cause trouble, it is really a legitimate question.

If the car is strapped down to the dyno, with the suspension compressed, how much is the alignment actually changing from the static alignment that is done at an alignment shop / robi /buschur?

Wouldn't it change drastically, at the very least the camber, with all the suspension compression?

I know every time I have my car on a mustang dyno the front and rear has much more negative camber when strapped down. I also know when the suspension compresses, the camber becomes more negative, which also changes toe.

 

The drawback to a strut type suspension is you lose camber gain in compression after a certion point this happens sooner in a lowered car. The evos rear multi-link in comparison continues to gain camber all the way to the limit of travel....they both add toe-in as the car gets compressed more and more so if you "overstrap a car on a dyno you will have higher friction losses...imo ymmv. As I think about Daves RS and the HP gains, I think with the whacked alignment he was needing to strap the car down tighter to keep it tracking straight. this + the extra scrub on the rollers really can add up to a ton of extra friction which robs WHP in a big way.

 

So wack alignment to the point of eating up his tires on the street correct? So people that have "decent" alignments that don't eat the tires won't have such a gain on the dyno since the alignment goes all out of wack once you strap the car down anyway, correct?

 

that would stand to reason, it might also be why new the Evo dyno #'s can be over 15% off one car to another....friction where ever you find it will kill HP

 

I love you're posts Dave, always something new and interesting

 

razorlab,

I agree, the car being overtightened on a dyno would squat the car and in turn could very well change the alignment. I never actually thought of that before. BUT, we do not pull the car down so hard that it puts much extra squat in it. My car is on the dyno right now actually for some turbo testing. When I release it I am going to measure before and after ride heights to see how much it is pulled, if at all.

Our tie downs are quite a bit behind the car and about 2.5' infront of the car. So it pulls the car forward/back more than straight down. Of course there is some downward pressure on it.

 

That would be good data to have David.

Of course, every dyno setup will be different, but since we are talking about your specific dyno setup in this thread, that data would be valuable.

I know for sure 100% my alignment changes on the local Mustang dyno that I use alot. The rear wheels actually tuck in the fender a tad when its strapped down.

 

Report me or shut up.... those are your two choices....

Keith

 

Crap, I got so excited with the new numbers from the turbo I forgot to measure the car. Sorry.
