Does having the roof off affect acceleration performance?
Hi Everyone,
I was curious to know what everyone thought about acceleration performance with the targa top removed? My feeling is from 0-60 the difference would be negligible but anything above that the hatch area would act like a parachute and diminish performance significantly due to the increased drag. Anyone have any thoughts?
Thanks,
Joe

Are you going to racing on the track? If not I would say Who Cares.. I think some us go to far in to this performance quest, (myself included) when we step back and think about it a min, what difference does it make if the goes 3 mph faster with the top on? Are you not going to be thrilled to be going over 130 mph anyway? How long do you think you will stay at top speed? You know what I mean.. 2-3 hp here and 1 or 2 there, yea it is always best to get all you can with-in reason, but diminishing returns on $$ spent as we squeeze more out it, I am happy as hell in my convertible with top down punching off from a roll or dead stop but I really like staying in 2nd and hauling down twisting road, I know it would be better handling as a hardtop BUT I don't want a hardtop I want to feel the air.. My .02cents (I had a little caffeine this am, so I am a bit chatty this am....lololol :cheers:

Well the reason I posted the question was because yesterday I raced an Fbody ramair from a stop. I pulled probably about 7 car lengths on him in the first 200 feet or so and we went up to about 130 mph. He never caught me I was just curious if I would have been further ahead if I had the roof on and windows closed.
My feeling is 3 mph faster can mean the difference between winning and losing whether on the street or track but I am very competetive

Mellow,
FWIW you can't race at any track without the roof in.
PS You said the other day you were driving a GrandPrix while the vette is in the shop. I remember when I met you on Dixie Hwy and I was driving a Grand Prix waiting on my 01 to arrive.

I would think that at 130mph in the coupe, you would have to hold on tight to keep from blowing out of the vette. The wind buffeting had to be intense.
