One time at the Drags this year (whilst I was in Brisbane visiting - Willowbank), their were two evo's racing, they were mates.. I think they were Evo 7's but maybe 9's.. cant remember.
I went for a chat as usual..
One Red, one white.. they had the same mods more or less..
The Red Evo was experimenting with Drag Times with the Wing on then with the Wing off..
He recorded quicker times with the wing removed, a noticeable difference too, both in ET and MPH, up to 0.3 sec quicker (in the 12 sec bracket)..
I was surprised at the difference.
Choice is yours.
"but now the secret is out, hehe"
Anyone else experimented with wing removed for the drags?
