The Upper control arms correct the caster don't they? New upper control arms have to be used with the ball joints.

Ahh yes... did not know you were doing the arms. You got that issue covered fo'show. :thumbsup:

First off all, I would not even think of going 200 MPH with only a 6 point rollbar in the car. Second, go back and read this thread from the start and take the advice given. Third, I know this is old school but, tape short lengths of yarn all over your cars body and have someone drive it on the freeway while you watch from another car. If you see yarn going anyway but straight back, that is an area that is creating lift and you need to minmize those areas.

Good luck and be safe.

Woodtufting... the cheapest aero testing known to man. Its an old favorite of mine, and all it takes is $3.50 in yarn and a gross of butterfly bandaid's.

I've done it when I was at Grumman, but never heard the term Woodtufting. It was referred to as Vector Field Analysis....but I like the term Woodtufting better!

My car will take 170 to go 200 mph then a Z28 Camaro, but being that the power is there, I somehow have to calculate how much more power I would need then the Red Z28 to hit 200 mph in the same amount of time and was running about 18 psi, or what he says is 750 rwhp in his car if I remember corectly. If that number is 170 hp, I need to fill with race gas and turn up the boost about 3-4 psi to make the same 200 mph standing mile. Is there a way to figure that out??
Also a 71 Chevelle aerodynamically has 8% lift at 100 mph as it came from the factory. I heard this is proportional, If so, would that mean I have 16% lift at 200 mph, or 608 lbs of total vehicle lift being It weighs 3800 lbs??
What do you think??

I am not sure about lift, but I think it was drag that increases exponentially with more mph, so rather than double, it may be more like 10x. I'm sure someone will chime in with better info.

I always thought drag was exponentially and lift was proportionally??? I could surely be wrong!

I am trying not to sound like a
 

D$(& head, but you have people here with a lot of expierence telling you what you need to do or at least what direction that you need to go and you are ignoring their advice.

I have no seat time trying to run over 150 mph but aero plays a huge role.

Stick you hand or your head out the window doing 30 mph and then do it at 100 mph...the resistance is exponential not proportional. The best example I can think of is in stereo sound. If 2 watts produce 5 db, it will take 4 watts to produce 6 db and 16 watts to produce 7 db...get the picture.

Not sure if you remember NASCAR a few years ago when all of the cars, shape similar to yours but with lots of wind tunnel work, were flying off the track. That is when roof flaps and restrictor plates started showing up.

I respect your dream of running 200, but you may need to rethink the vehicle to get you there. You can't get the power to the ground if the wheels are not touching the track....and no one has brought up tire that will not fail at those speeds.

Everyone is trying to keep you safe but it seems that you are turning a deaf ear.

Or not... I have heard everything, Whay do you think I am researching drag and lift?? Is there something someone wrote I dod not hear???
